Description

Display state control method and device

technical field

The invention relates to the field of communication technology, in particular to a display screen state control method and device.

Background technique

With the rapid development of communication technology, smart terminals are becoming more and more popular and become an indispensable device in people's life. People can learn, entertain and so on through smart terminals.

Currently, judging the proximity or distance between the smart terminal and an external object to control the screen of the smart terminal to turn off or turn on is a necessary function of the smart terminal. A smart terminal usually utilizes an infrared transmitter and an infrared receiver to detect the proximity or distance between the smart terminal and an external object. The infrared emitter emits infrared rays, which are reflected by obstacles to form reflected light. After receiving the reflected light, the infrared receiver judges whether the smart terminal is close to or far away from the obstacle according to the intensity value of the reflected light.

However, in practical applications, the external environment also contains infrared rays, for example, sunlight contains a large amount of infrared rays. Especially under strong sunlight, the infrared rays are more intense. At this time, the infrared receiver in the smart terminal will be affected by infrared rays in the external environment. When the user uses the smart terminal in a strong light environment, because the posture of the smart terminal is constantly changing, the receiving angle of the infrared receiver in the smart terminal is also constantly changing, which causes the infrared intensity value received by the infrared receiver to be in a fluctuating state, thus As a result, the screen of the smart terminal keeps turning off and on, that is, the screen flickers.

Please refer to FIG. 1 , which is a schematic structural diagram of a terminal 1000 in an embodiment of the present invention. The terminal 1000 is, for example, an electronic device such as a mobile phone or a tablet computer. It can be understood that the terminal 1000 includes but is not limited to examples of this implementation manner.

The terminal 1000 includes a panel assembly 100 and a housing 200 . The panel assembly 100 is disposed on and connected to the casing 200 . It can be understood that the terminal 1000 may also include a receiver. Correspondingly, the non-display area 100a of the panel assembly 100 is provided with an opening 300 for the receiver to emit sound. Area 100a. The display area 100b of the panel assembly 100 can be used for displaying images or for users to touch and manipulate.

Wherein, the panel assembly 100 may be a touch panel assembly, a panel assembly or a terminal panel assembly with other functions, and the like.

Please refer to FIG. 2 . FIG. 2 is a first structural diagram of the panel assembly 100 in the embodiment of the present invention. The panel assembly 100 includes a sensor module 11 , a cover assembly 12 and a control circuit 13 . The sensor module 11 is disposed on one side of the inner surface of the cover assembly 12 , and the sensor module 11 is spaced apart from the cover assembly 12 . The control circuit 13 is communicatively connected with the sensor module 11 and the cover assembly 12 . In this embodiment, the control circuit 13 is a main board, the sensor module 11 is a proximity sensor, and the sensor module 11 is fixedly arranged on the main board.

Wherein, the sensor module 11 includes a first signal transmitter 111 , a first signal receiver 112 and a second signal receiver 113 .

The signal transmitter 111 is used for transmitting signals to the outside. The signal receiver 112 and the signal receiver 113 are used for receiving signals reflected by external objects.

In some embodiments, the sensor module 11 may also only include the signal transmitter 111 and the signal receiver 112 .

The above-mentioned signals may be optical signals such as infrared rays and lasers, or sound wave signals such as ultrasonic waves. In the following, only the signal is an optical signal, the signal transmitter is an optical transmitter, and the signal receiver is an optical receiver for illustration.

In some embodiments, the first light emitter 111 is used to emit detection light with a wavelength greater than 850nm, such as infrared light, which is an infrared emitter. For example, the first light emitter 111 may be an infrared emitting LED (Light Emitting Diode, light emitting diode).

Correspondingly, the first light receiver 112 may be an infrared light receiver for receiving the low beam signal formed after the detection light is reflected by the barrier 70 . The barrier 70 is generally a human face, and is applied to a scene when the terminal approaches or moves away from the user's face during a call.

Correspondingly, the second light receiver 113 may be an infrared light receiver for receiving the high beam signal formed after the detection light is reflected by the barrier 70 .

Wherein, the low beam signal indicates that the light receiver reflected by the barrier is relatively close to the first light transmitter 111, and the high beam signal indicates that the light receiver reflected by the barrier is far away from the first light transmitter 111. The first light emitter 111 is far away.

The distance between the first light receiver 112 and the first light emitter 111 is smaller than the distance between the second light receiver 113 and the first light emitter 111 . Therefore, when the cover assembly 12 is far away from the blocking object, the light intensity change detection of the second light receiver 113 is more sensitive. When the cover assembly 12 is closer to the blocking object, the light intensity change detection of the first light receiver 112 is more sensitive. Therefore, in a specific application, the terminal can judge whether the terminal is far away or close according to the light intensity values of the reflected light received by the first light receiver 112 and the second light receiver 113 at the same time, which can greatly improve the accuracy of judgment. It is beneficial to improve the user experience.

In this embodiment, the first light transmitter 111 and the first light receiver 112 can be integrated in a first integrated chip to form a two-in-one chip. Of course, it can also be separately configured as two independent chips.

Wherein, the cover plate assembly 12 includes a cover plate 121, a first adhesive layer 122 disposed on the inner surface of the cover plate 121, and a second adhesive layer 123 disposed on the side of the first adhesive layer 122 away from the cover plate 121 . The first adhesion layer 122 completely covers the second adhesion layer 123 . Wherein, the first adhesion layer 122 and the second adhesion layer 123 constitute an adhesion layer.

The first adhesive layer 122 and the second adhesive layer 123 are arranged to achieve the effect of hiding the internal structural components of the terminal 1000 and the second adhesive layer 123 . That is, when the user observes the outside of the cover plate 121 , only the first adhesion layer 122 can be seen, but the second adhesion layer 123 cannot be seen.

Wherein, the cover plate 121 may be a transparent glass cover plate. In some embodiments, the cover plate 121 may be a glass cover plate made of materials such as sapphire.

Wherein, the adhesion layer may be an ink layer, or a coating formed of other materials. In the following, only the adhesion layer is an ink layer, the first adhesion layer is a light-transmitting ink layer, and the second adhesion layer is a light-shielding ink layer for illustration.

In this embodiment, the light-transmitting ink layer 122 is a light-transmitting ink layer for transmitting most light. The light transmittance of the ink layer can be set according to actual needs. Generally, the visible light (such as visible light with a wavelength of 550nm) transmittance of the light-transmissive ink layer 122 is between 2% and 10%, and the optical signal of the proximity sensor (such as a wavelength of 550nm) 850nm infrared) transmittance greater than or equal to 80%.

The light-transmitting ink layer 122 may include several light-transmitting ink sub-layers 1221 . For example, in this embodiment, the light-transmitting ink layer 122 has three light-transmitting ink sub-layers 1221, and each light-transmitting ink sub-layer 1221 is formed by spraying or printing a white ink. Of course, the white ink is only an example, and the light-transmitting ink layer 122 can also be designed in other colors according to different aesthetic requirements.

It can be understood that when the color of the light-transmitting ink layer 122 is different, the appearance color performance of the terminal 1000 is also different. For example, when the transparent ink layer 122 is white ink, the appearance of the terminal 1000 is white, that is, the terminal 1000 is a white model. When the transparent ink layer 122 is gold ink, the appearance of the terminal 1000 is gold, that is, the terminal 1000 is a gold model.

The light-shielding ink layer 123 is a light-shielding ink layer for blocking most light. The light-shielding ink layer 123 can be formed by spraying or printing black ink. The light-shielding ink layer 123 includes a first region and a second region. The light transmittance of the first area is greater than the light transmittance of the second area. The first region can be understood as a light-transmitting region for transmitting most light. The second area can be understood as a light-shielding area, which is used to block most of the light.

Wherein, the light-transmitting ink layer 122 covers the first area on the light-shielding ink layer 123 .

Wherein, the transmittance of the light-transmitting ink layer 122 to light is greater than the transmittance of the light-shielding ink layer 123 to light.

The aforementioned transmittance may include transmittance to infrared rays, transmittance to laser light, and transmittance to visible light.

In some embodiments, a first light through hole 124 and a second light through hole 125 are opened on the light shielding ink layer 123 . The first light hole 124 and the second light hole 125 are used for passing light. The first light hole 124 and the second light hole 125 form a first area, and the area on the light-shielding ink layer 123 other than the first light hole 124 and the second light hole 125 is a second area. It can be understood that the first light hole 124 and the second light hole 125 may also be filled with a light-transmitting material, and the color of the light-transmitting material may be the same as that of the light-transmitting ink layer 122 . Wherein, the first light through hole 124 may include a first light emitting hole 1241 and a first light receiving hole 1242 which are separated. The first light emitter 111 is opposite to the first light emitting hole 1241 , and emits detection light through the first light emitting hole 1241 . The first light receiver 112 is opposite to the first light receiving hole 1242 and receives the reflected light of the detection light through the first light receiving hole 1242 .

The second light hole 125 is opposite to the second light receiver 113 , and the second light receiver 113 receives the reflected light of the detection light through the second light hole 125 .

Wherein, the shapes of the first light emitting hole 1241 , the first light receiving hole 1242 and the second light passing hole 125 can be set according to actual needs. For example, it may be in the shape of a circle, a rectangle, a rounded rectangle, or the like. In this embodiment, in order to improve the ability of the first light receiver 112 and the second light receiver 113 to receive light signals and improve the sensitivity of the sensor, the opening area of the first light receiving hole 1242 and the second light through hole 125 can be made larger than that of the first light receiving hole 1242 and the second light passing hole 125. The opening area of a light emission hole 1241 .

Understandably, as shown in FIG. 3 , in some other embodiments, the first light through hole 124 can also be a larger hole, which simultaneously supplies the first light transmitter 111 and the first light receiver 112 use.

In this embodiment, the control circuit 13 is connected in communication with the first light transmitter 111, the first light receiver 112 and the second light receiver 113, and the first light transmitter 111, the first light receiver 112 and The second light receivers 113 are all fixedly disposed on the main board.

For example, when the panel assembly 100 is applied to a mobile phone, since the first light receiver 112 and the second light receiver 113 are at different distances from the first light emitter 111, the first light receiver 112 is closer to the The first light emitter 111, when the panel assembly 100 is close to the barrier, the second light receiver 113 receives little light due to the distance from the first light emitter 111, and the light intensity changes The value does not change much with distance. When the panel assembly 100 is far away from the barrier, because the reflected light is weak, the light emitted by the first light emitter 111 directly enters the first light receiver 112 by internal reflection, and the first light receiver 112 receives The base value of the light intensity value is larger, and the cover plate is farther away from the barrier, and the light intensity value of the reflected light is smaller, so the reflected light received by the first light receiver has no obvious change in the detected light intensity . The distance between the second light receiver 113 and the first light transmitter 111 is relatively far from the first light receiver 112 , so the light emitted by the first light transmitter 111 enters the second light receiver 113 through internal reflection. There are few parts, the basic light intensity value is small, and the light intensity change is relatively large after the reflected light enters the second light receiver 113 .

During the call process of the terminal, the control circuit 13 controls the first light transmitter 111 to emit detection light, and judges the light intensity value of the reflected light received by the first light receiver 112 and the second light receiver 113. Whether the terminal of the panel assembly 100 is close to or far from the face. When it is judged to be far away from the face, the cover assembly 12 is controlled to turn on the screen, and when it is judged to be close to the face, the screen of the cover assembly 12 is controlled to turn off.

Wherein, when the light intensity value received by the first light receiver 113 reaches the first proximity threshold or the light intensity value received by the second light receiver 113 reaches the second proximity threshold, it is determined that the terminal is close to the face. When the light intensity value received by the first light receiver 113 reaches the first distance threshold and the light intensity value received by the second light receiver 113 reaches the second distance threshold, it is determined that the terminal is far away from the face.

Referring to FIG. 4 , FIG. 4 is another structural schematic diagram of the panel assembly 100 in the embodiment of the present invention. The panel assembly 100 includes a sensor module 21 , a cover assembly 22 and a control circuit 23 . The sensor module 21 is disposed on one side of the inner surface of the cover assembly 22 , and the sensor module 21 is spaced apart from the cover assembly 22 . The control circuit 23 is communicatively connected with the sensor module 21 and the cover assembly 22 . In this embodiment, the control circuit 23 is a main board, and the sensor module 21 is fixedly arranged on the main board.

Wherein, the sensor module 21 includes a first light transmitter 211 , a first light receiver 212 , a second light receiver 213 , a second light transmitter 214 , a first ambient brightness sensor 215 and a second ambient brightness sensor 216 .

Understandably, in some embodiments, the sensor module 21 may also include a circuit board. The first light transmitter 211 , the first light receiver 212 , the second light receiver 213 , the second light transmitter 214 , the first ambient brightness sensor 215 and the second ambient brightness sensor 216 may be disposed on the circuit board.

Wherein, the first light emitter 211 and the second light emitter 214 are both used to emit invisible light with a wavelength greater than 850nm, such as infrared light.

Both the first light emitter 211 and the second light emitter 214 are infrared light emitters. Both the first light receiver 212 and the second light receiver 213 can be infrared light receivers. The first light receiver 212 is used for receiving the low beam signal formed after the detection light is reflected by the barrier. The second light receiver 214 is used for receiving the high beam signal formed after the detection light is reflected by the barrier. The distance between the first light receiver 212 and the first light emitter 211 is smaller than the distance between the second light receiver 213 and the first light emitter 211 . Wherein, the low beam signal indicates that the light receiver reflected by the barrier is relatively close to the first light transmitter 211, and the high beam signal indicates that the light receiver reflected by the barrier is far away from the first light transmitter 211. The first light emitter 211 is far away.

The distance between the first light receiver 212 and the first light emitter 211 is smaller than the distance between the second light receiver 213 and the first light emitter 211 . Therefore, when the first light emitter 211 is used as the sender of the detection light, and when the panel assembly 100 is far away from the barrier, the detection of the light intensity change of the second light receiver is more sensitive; when the panel assembly 100 When the distance to the blocking object is closer, the detection of the light intensity change of the first light receiver is more sensitive. When the second light emitter 214 is used as the detector light emitter, and when the panel assembly 100 is far away from the barrier, the light intensity change detection of the second light receiver 214 is more sensitive; when the panel assembly 100 is far away from When the obstacle is closer, the first light receiver 212 is more sensitive in detecting the light intensity change.

In this embodiment, the control circuit 23 can select one of the first light emitter 211 and the second light emitter 214 as the sender of the detection light, usually, the first light emitter 211 is used as the detection light When the control circuit 23 detects that the first light emitter 211 is abnormal or damaged, the second light emitter 214 is used as the emitter of the detection light.

In some embodiments, the first light emitter 211 , the first light receiver 212 and the first ambient brightness sensor 215 can be integrated on one integrated chip to form a three-in-one chip. The second light transmitter 214 , the second light receiver 213 and the second ambient brightness sensor 216 may be integrated on another integrated chip to form another three-in-one chip.

In some embodiments, as shown in FIG. 5 , the sensor module 21 may only include a light emitter 211 , a first light receiver 212 , a second light receiver 213 and an ambient brightness sensor 216 . The light transmitter 211 , the first light receiver 212 , the second light receiver 213 and the ambient brightness sensor 216 can be arranged on a circuit board.

The light transmitter 211 and the first light receiver 212 may be integrated on an integrated chip to form a two-in-one chip. The second light receiver 213 and the ambient brightness sensor 216 may be integrated on another integrated chip to form another two-in-one chip. The above two two-in-one chips can be arranged on the circuit board at intervals.

The distance between the two two-in-one chips is between 2mm and 12mm. The distance is the distance between the geometric centers of the two 2-in-1 chips.

The cover assembly 22 includes a cover 221 , a light-transmitting ink layer 222 disposed on an inner surface of the cover 221 , and a light-shielding ink layer 223 disposed on a side of the light-transmitting ink layer 222 away from the cover 221 . Wherein, the light-transmitting ink layer 122 and the light-shielding ink layer 123 constitute an ink layer.

Wherein, the light-transmitting ink layer 222 may include multiple light-transmitting ink sub-layers 2221. For example, in this embodiment, the light-transmitting ink layer 222 has three light-transmitting ink sub-layers 2221, and each light-transmitting ink sub-layer 2221 are formed by white ink spraying or printing. Of course, the white ink is only an example, and the light-transmitting ink layer 222 can also be designed in other colors according to different aesthetic requirements.

The light-shielding ink layer 223 can be formed by spraying or printing black ink. A first light hole 224 and a second light hole 225 are formed on the light-shielding ink layer 223 .

In this embodiment, the light-transmitting ink layer 222 located on the light-shielding ink layer 223 may be a light-transmitting ink layer. The light transmittance of the ink layer can be set according to actual needs. Generally, the visible light (such as the visible light with a wavelength of 550nm) transmittance of the light-transmissive ink layer 222 is between 2%-10%, and the light signal of the proximity sensor (such as with a wavelength of 850nm infrared) transmittance greater than or equal to 80%.

Wherein, the first light through hole 224 may include a first light emitting hole 2241 and a first light receiving hole 2242 which are separated. The first light emitter 211 is opposite to the first light emitting hole 2241 , and emits detection light through the first light emitting hole 2241 . The first light receiver 212 and the first environment brightness sensor 215 are opposite to the first light receiving hole 2242, the first light receiver 212 receives the reflected light of the detection light through the first light receiving hole 2242, the first environment The brightness sensor 215 detects the ambient light intensity through the first light receiving hole 2242 .

The second light through hole 225 may include a second light emitting hole 2251 and a second light receiving hole 2252 which are separated. The second light emitter 214 is opposite to the second light emitting hole 2251 and emits detection light through the second light emitting hole 2251 . The second light receiving hole 2252 is opposite to the second light receiver 213 and the second environment brightness sensor 216, the second light receiver 213 receives the reflected light of the detection light through the second light receiving hole 2252, the second environment The brightness sensor 216 detects the ambient light intensity through the second light receiving hole 2252 .

Understandably, as shown in FIG. 6 , in some other embodiments, the first light through hole 224 can also be a larger hole, which simultaneously supplies the first light emitter 211 and the first light receiver 212 And the first ambient brightness sensor 215 is used.

The second light hole 225 can also be a larger hole, which is used by the second light emitter 214 , the second light receiver 213 and the second ambient brightness sensor 216 at the same time.

Taking the panel assembly 100 applied to a mobile phone as an example for illustration, under normal circumstances, the control circuit 23 selects the first light emitter 211 as the sender of the detection light, and the second light emitter 214 does not work.

In some embodiments, as shown in FIG. 7 , the cover assembly 22 may only include a cover 221 and a light-transmitting ink layer 222 disposed on the inner surface of the cover 221 .

Wherein, the transparent ink layer 222 can be formed by spraying or printing special ink. For example, the specialty ink may be an infrared ink (IR ink). The transmittance of IR ink to infrared rays is greater than or equal to 80%, so it can pass through most infrared rays. The appearance of IR ink is black ink.

Wherein, a functional area can be set on the light-transmitting ink layer 222 at a position corresponding to the ambient brightness sensor 216, and ink that can transmit ambient light can be sprayed or printed on the functional area. This functional area is used to pass ambient light so that the ambient brightness sensor 216 detects the ambient brightness.

The display screen state control method controls the state of the display screen according to the distance state between the terminal and the external object. The distance state includes a far state and an approach state. The status of the display includes on and off.

The method for controlling the state of the display screen will be described below only by taking the sensor module as a proximity sensor, and the proximity sensor includes a signal transmitter and a signal receiver as an example. Wherein, the signal transmitter can be an infrared transmitter, and the signal receiver can be an infrared receiver.

As shown in Figure 8, the display screen state control method may include the following steps:

S510. Acquire a basic signal strength value, where the basic signal strength value is a signal strength value detected by the proximity sensor when one side of the display screen of the terminal is not blocked by an external object.

In practical applications, after the terminal is turned on and running, the infrared emitter can emit a detection signal outward. At this time, there is no object blocking one side of the terminal display screen. The signal emitted by the infrared transmitter to the outside is not reflected by the object. At this time, part of the signal emitted by the infrared transmitter directly enters the infrared receiver through the diffraction inside the terminal. The signals received by the infrared receiver all come from the diffraction inside the terminal, so the signal strength received by the infrared receiver is at a minimum. At this time, the signal strength value detected by the proximity sensor may be used as the basic signal strength value.

In some embodiments, after the terminal is turned on and running, the signal strength values received by the infrared receiver may be acquired multiple times, and the smallest one is taken as the base value of the signal strength.

S520. Acquire the threshold adjustment amount of the proximity sensor according to the environment state of the terminal.

Wherein, the environment state where the terminal is located represents the light intensity of the environment where the terminal is located. The environmental state may include a strong light environment and a low light environment. For example, the environment state under strong sunlight is a strong light environment, and the environment state indoors is a low light environment. The environment state may also include a plurality of gradation states divided between high-light environment and low-light environment.

The threshold adjustment amount is used to adjust the threshold of the proximity sensor. When the terminal is in different environmental states, the acquired threshold adjustment amounts are different. Therefore, when the terminal is in different environmental states, it has different thresholds. The threshold is used to judge whether the terminal is close to or far away from the external object, so as to control the state of the display screen of the terminal.

In some embodiments, as shown in FIG. 9 , obtaining the threshold adjustment value of the proximity sensor according to the environmental state of the terminal includes the following steps:

S521, when the infrared transmitter is turned off, acquire the detection value of the infrared receiver;

S522. Acquire a threshold adjustment amount of the proximity sensor according to the detection value.

In practical applications, the terminal can control the infrared transmitter to turn off, and obtain the detection value of the infrared receiver at this time. Since the infrared transmitter is turned off, all the infrared rays entering the infrared receiver come from the external environment at this time. According to the detection value of the infrared receiver at this time, the infrared intensity of the environment where the terminal is located can be determined, that is, the environmental state where the terminal is located can be determined.

The corresponding relationship between the infrared detection value and the threshold adjustment amount can be set in advance in the terminal. After obtaining the detection value of the infrared receiver, the terminal obtains the corresponding threshold adjustment amount according to the detection value. Wherein, the threshold adjustment amount may be a signal strength value or a percentage.

In practical applications, there is a consistent change relationship between the ambient brightness and the ambient infrared intensity in a strong light environment, that is, the greater the ambient brightness, the stronger the ambient infrared intensity, and the smaller the ambient brightness, the weaker the ambient infrared intensity.

Therefore, in some embodiments, the ambient brightness of the environment where the terminal is located may also be detected by an ambient brightness sensor in the terminal. Moreover, the corresponding relationship between the ambient brightness and the threshold adjustment amount of the proximity sensor is set in advance in the terminal. The terminal may acquire the threshold adjustment value of the proximity sensor according to the detected ambient brightness and the corresponding relationship.

In some embodiments, as shown in FIG. 10 , obtaining the threshold adjustment value of the proximity sensor according to the detection value includes the following steps:

S5221, judging whether the detection value is greater than the strong light threshold;

S5222. If the detection value is greater than the strong light threshold, acquire a first threshold adjustment amount;

S5223. If the detection value is not greater than the strong light threshold, acquire a second threshold adjustment amount.

Wherein, the strong light threshold may be an infrared intensity value preset in the terminal. The strong light threshold represents a dividing point between a strong light environment and a low light environment. That is, when the infrared intensity value in the environment is greater than the strong light threshold, it indicates that the environmental state is a strong light environment; when the infrared intensity value in the environment is not greater than the strong light threshold, it indicates that the environmental state is a low light environment.

After the terminal obtains the detection value of the proximity sensor, it may determine whether the detection value is greater than the strong light threshold, so as to determine whether the environmental state of the terminal is a strong light environment or a low light environment. In a strong light environment, the threshold adjustment amount acquired by the terminal is the first threshold adjustment amount. In a low-light environment, the threshold adjustment amount obtained by the terminal is the second threshold adjustment amount. Wherein, the second threshold adjustment amount is smaller than the first threshold adjustment amount. For example, the first threshold adjustment amount is 600, and the second threshold adjustment amount is 300.

In some embodiments, as shown in FIG. 11 , obtaining the threshold adjustment amount of the proximity sensor according to the detection value includes the following steps:

S5224, determine the interval where the detection value is located;

S5225. Acquire a corresponding threshold adjustment amount according to the interval and a preset mapping relationship, where the preset mapping relationship is a mapping relationship between an interval and a threshold adjustment amount.

In practical applications, the detection value may be divided into multiple intervals in advance, and information of the multiple intervals may be stored in the terminal. For example, multiple intervals such as (0, 200], (200, 400], (400, 600], (600, 800]) can be divided into detection values.

At the same time, the mapping relationship between the multiple intervals and the threshold adjustment amount may be preset, and the preset mapping relationship may be stored in the terminal. For example, the preset mapping relationship may be the mapping relationship shown in Table 1.

interval threshold adjustment (0, 200] 300 (200, 400] 500 (400, 600] 700 (600,800] 900

Table 1

After acquiring the detection value of the proximity sensor, the terminal may determine the interval in which the detection value is located, and obtain the corresponding threshold adjustment amount according to the determined interval and the preset mapping relationship. For example, if the detection value of the proximity sensor is 500, it can be determined that the detection value is in the interval (400, 600], and then the corresponding threshold adjustment amount is 700.

Continue to refer to FIG. 8 .

S530. Determine a threshold of the proximity sensor according to the base signal strength value and the threshold adjustment value.

In practical applications, after the terminal obtains the threshold adjustment amount of the proximity sensor, it may determine the threshold value of the proximity sensor according to the above-mentioned basic signal strength value and the threshold adjustment amount.

Wherein, when the threshold adjustment amount is a signal strength value, the value may be added to the base value of the signal strength as the threshold of the proximity sensor. For example, if the base value of the signal strength is 1000, and the acquired threshold adjustment value is 600, then the threshold value of the proximity sensor can be determined to be 1600.

When the threshold adjustment amount is a percentage, the signal strength corresponding to the percentage may be added to the basic value of the signal strength as the threshold of the proximity sensor. For example, if the base value of the signal strength is 1000, and the acquired threshold adjustment value is 50%, then the threshold value of the proximity sensor may be determined to be 1500.

S540. Control the state of the display screen according to the threshold and the signal strength value detected by the proximity sensor.

In practical applications, after the terminal determines the threshold value of the proximity sensor, it can transmit an infrared signal through the infrared transmitter when it needs to control the state of the display screen. The infrared receiver continues to receive the returned signal, and the proximity sensor detects the return signal. signal strength value. At this time, one side of the display screen of the terminal may be blocked by an object (for example, the user's face), or may not be blocked by an object. For example, when the terminal is in a call state, the signal strength value is continuously acquired. The state of the display is then controlled based on this threshold and the detected signal strength value.

In some embodiments, as shown in FIG. 12 , the threshold includes a first threshold, and controlling the state of the display screen according to the threshold and the signal strength value detected by the proximity sensor includes the following steps:

S541. When the display screen is in a bright screen state, determine whether the signal strength value detected by the proximity sensor is greater than a first threshold;

S542. If the signal strength value is greater than the first threshold, control the display screen to turn off.

In practical applications, the threshold may include the first threshold. The first threshold may be a high threshold. This high threshold is used to trigger the control display to turn off when the display is on.

When the display screen of the terminal is in a bright screen state, after the proximity sensor detects a signal strength value, the signal strength value is compared with the first threshold to determine whether the signal strength value is greater than the first threshold. When it is determined that the signal strength value is greater than the first threshold, it indicates that the terminal is in a close state to an external object (for example, the user's face), and at this time, the control display screen is turned off.

For example, if the first threshold value is 1800, and the detected signal strength value is 2000, then the signal strength value is greater than the first threshold value, and at this time, the control display screen is turned off.

In some embodiments, as shown in FIG. 13 , the threshold includes a second threshold, and controlling the state of the display screen according to the threshold and the signal strength value detected by the proximity sensor includes the following steps:

S543. When the display screen is in a screen-off state, determine whether the signal strength value detected by the proximity sensor is less than a second threshold;

S544. If the signal strength value is less than the second threshold, control the display screen to light up.

In practical applications, the threshold may include a second threshold. The second threshold may be a low threshold. This low threshold is used to trigger the control display to turn on when the display is off. For the same terminal, the low threshold is smaller than the above high threshold.

When the display screen of the terminal is in a screen-off state, after the proximity sensor detects a signal strength value, the signal strength value is compared with the second threshold to determine whether the signal strength value is smaller than the second threshold. When it is determined that the signal strength value is less than the second threshold, it means that the terminal is in a state of being far away from the external object (for example, the user's face), and at this time, the control display screen is turned on.

For example, if the second threshold value is 1600, and the detected signal strength value is 1500, then the signal strength value is less than the second threshold value, and at this time, the control display screen is turned on.

As can be seen from the above, the display screen state control method provided by the embodiment of the present invention obtains the basic signal strength value; obtains the threshold adjustment amount of the proximity sensor according to the environmental state where the terminal is located; determines the proximity sensor according to the basic signal strength value and the threshold adjustment amount. The threshold of the sensor; control the state of the display screen according to the threshold and the signal strength value detected by the proximity sensor. This solution obtains the threshold adjustment value of the proximity sensor according to the environmental state of the terminal, and then determines the threshold value of the proximity sensor. Therefore, when the terminal is in different environmental states, the threshold value of the proximity sensor is different, so that the state control of the terminal display screen is consistent with that of the terminal. The state of the environment in which the terminal is located can be adapted, so that the accuracy of the state control of the display screen can be improved, thereby improving the stability of the terminal.

The embodiment of the invention also relates to a display screen state control device. The display screen state control device controls the state of the display screen according to the distance state between the terminal and the external object. The distance state includes a far state and an approach state. The status of the display includes on and off.

As shown in FIG. 14 , the display screen state control device 600 includes: a first acquisition module 601 , a second acquisition module 602 , a determination module 603 , and a control module 604 .

The first obtaining module 601 is configured to obtain a basic signal strength value, where the basic signal strength value is a signal strength value detected by a proximity sensor when one side of the display screen of the terminal is not blocked by an external object.

In practical applications, after the terminal is turned on and running, the infrared emitter can emit a detection signal outward. At this time, there is no object blocking one side of the terminal display screen. The signal emitted by the infrared transmitter to the outside is not reflected by the object. At this time, part of the signal emitted by the infrared transmitter directly enters the infrared receiver through the diffraction inside the terminal. The signals received by the infrared receiver all come from the diffraction inside the terminal, so the signal strength received by the infrared receiver is at a minimum. At this time, the signal strength value detected by the proximity sensor may be used as the basic signal strength value. The first obtaining module 601 obtains the basic signal strength value through a proximity sensor.

In some embodiments, after the terminal is turned on and running, the signal strength values received by the infrared receiver may be acquired multiple times, and the smallest one is taken as the base value of the signal strength.

The second acquiring module 602 is configured to acquire the threshold adjustment amount of the proximity sensor according to the environment state of the terminal.

Wherein, the environment state where the terminal is located represents the light intensity of the environment where the terminal is located. The environmental state may include a strong light environment and a low light environment. For example, the environment state under strong sunlight is a strong light environment, and the environment state indoors is a low light environment. The environment state may also include a plurality of gradation states divided between high-light environment and low-light environment.

The second obtaining module 602 obtains the threshold adjustment amount of the proximity sensor according to the environment state of the terminal. The threshold adjustment amount is used to adjust the threshold of the proximity sensor. When the terminal is in different environmental states, the threshold adjustment amounts acquired by the second acquiring module 602 are different. Therefore, when the terminal is in different environmental states, it has different thresholds. The threshold is used to judge whether the terminal is close to or far away from the external object, so as to control the state of the display screen of the terminal.

In some embodiments, as shown in FIG. 15 , the second acquiring module 602 includes: a first acquiring submodule 6021 and a second acquiring submodule 6022 .

The first acquisition sub-module 6021 is used to acquire the detection value of the infrared receiver when the infrared transmitter is turned off;

The second obtaining sub-module 6022 is used to obtain the threshold adjustment amount of the proximity sensor according to the detection value.

In practical applications, the terminal can control the infrared transmitter to be turned off, and the first acquisition sub-module 6021 acquires the detection value of the infrared receiver at this time. Since the infrared transmitter is turned off, all the infrared rays entering the infrared receiver come from the external environment at this time. According to the detection value of the infrared receiver at this time, the infrared intensity of the environment where the terminal is located can be determined, that is, the environmental state where the terminal is located can be determined.

The corresponding relationship between the infrared detection value and the threshold adjustment amount can be set in advance in the terminal. After the first acquisition submodule 6021 acquires the detection value of the infrared receiver, the second acquisition submodule 6022 acquires the corresponding threshold adjustment amount according to the detection value. Wherein, the threshold adjustment amount may be a signal strength value or a percentage.

In practical applications, there is a consistent change relationship between the ambient brightness and the ambient infrared intensity in a strong light environment, that is, the greater the ambient brightness, the stronger the ambient infrared intensity, and the smaller the ambient brightness, the weaker the ambient infrared intensity.

Therefore, in some embodiments, the first acquiring submodule 6021 may also detect the ambient brightness of the environment where the terminal is located through the ambient brightness sensor in the terminal. Moreover, the corresponding relationship between the ambient brightness and the threshold adjustment amount of the proximity sensor is set in advance in the terminal. The second obtaining submodule 6022 may obtain the threshold adjustment value of the proximity sensor according to the detected ambient brightness and the corresponding relationship.

In some embodiments, the second acquisition submodule 6022 is used to perform the following steps:

Judging whether the detection value is greater than the strong light threshold;

If the detected value is greater than the strong light threshold, then obtain a first threshold adjustment amount;

If the detection value is not greater than the strong light threshold, a second threshold adjustment amount is acquired.

Wherein, the strong light threshold may be an infrared intensity value preset in the terminal. The strong light threshold represents a dividing point between a strong light environment and a low light environment. That is, when the infrared intensity value in the environment is greater than the strong light threshold, it indicates that the environmental state is a strong light environment; when the infrared intensity value in the environment is not greater than the strong light threshold, it indicates that the environmental state is a low light environment.

After the first acquisition submodule 6021 acquires the detection value of the proximity sensor, the second acquisition submodule 6022 can determine whether the detection value is greater than the strong light threshold, so as to determine whether the environment state of the terminal is a strong light environment or a low light environment. In a strong light environment, the threshold adjustment amount acquired by the second acquisition submodule 6022 is the first threshold adjustment amount. In a low-light environment, the threshold adjustment amount acquired by the second acquisition submodule 6022 is the second threshold adjustment amount. Wherein, the second threshold adjustment amount is smaller than the first threshold adjustment amount. For example, the first threshold adjustment amount is 600, and the second threshold adjustment amount is 300.

In some embodiments, the second acquisition submodule 6022 is used to perform the following steps:

Determine the interval where the detection value is located;

The corresponding threshold adjustment amount is acquired according to the interval and the preset mapping relationship, and the preset mapping relationship is a mapping relationship between the interval and the threshold adjustment amount.

In practical applications, the detection value may be divided into multiple intervals in advance, and information of the multiple intervals may be stored in the terminal. For example, multiple intervals such as (0, 200], (200, 400], (400, 600], (600, 800]) can be divided into detection values.

At the same time, the mapping relationship between the multiple intervals and the threshold adjustment amount may be preset, and the preset mapping relationship may be stored in the terminal. For example, the preset mapping relationship may be the mapping relationship shown in Table 2.

interval threshold adjustment (0, 200] 300 (200, 400] 500 (400, 600] 700 (600,800] 900

Table 2

After the first acquisition submodule 6021 acquires the detection value of the proximity sensor, the second acquisition submodule 6022 can determine the interval of the detection value, and obtain the corresponding threshold adjustment amount according to the determined interval and the preset mapping relationship. For example, if the detection value of the proximity sensor is 500, it can be determined that the detection value is in the interval (400, 600], and then the corresponding threshold adjustment amount is 700.

A determining module 603, configured to determine the threshold of the proximity sensor according to the base signal strength value and the threshold adjustment amount.

In practical applications, after the second acquisition module 602 acquires the threshold adjustment amount of the proximity sensor, the determination module 603 may determine the threshold value of the proximity sensor according to the above-mentioned basic signal strength value and the threshold adjustment amount.

Wherein, when the threshold adjustment amount is a signal strength value, the value may be added to the base value of the signal strength as the threshold of the proximity sensor. For example, if the base value of the signal strength is 1000, and the acquired threshold adjustment value is 600, then the threshold value of the proximity sensor can be determined to be 1600.

When the threshold adjustment amount is a percentage, the signal strength corresponding to the percentage may be added to the basic value of the signal strength as the threshold of the proximity sensor. For example, if the base value of the signal strength is 1000, and the acquired threshold adjustment value is 50%, then the threshold value of the proximity sensor may be determined to be 1500.

The control module 604 is configured to control the state of the display screen according to the threshold and the signal strength value detected by the proximity sensor.

In practical applications, after the determination module 603 determines the threshold value of the proximity sensor, the terminal can transmit infrared signals through the infrared transmitter when it needs to control the state of the display screen, and the infrared receiver continues to receive the returned signals, and the proximity sensor detects The signal strength value of this returned signal. At this time, one side of the display screen of the terminal may be blocked by an object (for example, the user's face), or may not be blocked by an object. For example, when the terminal is in a call state, the signal strength value is continuously acquired. Subsequently, the control module 604 controls the state of the display screen according to the threshold and the signal strength value detected by the proximity sensor.

In some embodiments, the control module 604 is used to perform the following steps:

When the display screen is in a bright screen state, it is judged whether the signal strength value detected by the proximity sensor is greater than the first threshold;

If the signal strength value is greater than the first threshold, the display screen is controlled to turn off.

In practical applications, the threshold may include the first threshold. The first threshold may be a high threshold. This high threshold is used to trigger the control display to turn off when the display is on.

When the display screen of the terminal is in the bright screen state, after the proximity sensor detects a signal strength value, the control module 604 compares the signal strength value with the first threshold to determine whether the signal strength value is greater than the first threshold. When it is determined that the signal strength value is greater than the first threshold, it indicates that the terminal is in a close state to an external object (for example, the user's face), and at this time, the control display screen is turned off.

For example, if the first threshold value is 1800, and the detected signal strength value is 2000, then the signal strength value is greater than the first threshold value, and at this time, the control display screen is turned off.

In some embodiments, the control module 604 is used to perform the following steps:

When the display screen is in the screen-off state, it is judged whether the signal strength value detected by the proximity sensor is less than the second threshold;

If the signal strength value is less than the second threshold, the display screen is controlled to light up.

In practical applications, the threshold may include a second threshold. The second threshold may be a low threshold. This low threshold is used to trigger the control display to turn on when the display is off. For the same terminal, the low threshold is smaller than the above high threshold.

When the display screen of the terminal is off, after the proximity sensor detects a signal strength value, the control module 604 compares the signal strength value with the second threshold to determine whether the signal strength value is smaller than the second threshold. When it is determined that the signal strength value is less than the second threshold, it means that the terminal is in a state of being far away from the external object (for example, the user's face), and at this time, the control display screen is turned on.

For example, if the second threshold value is 1600, and the detected signal strength value is 1500, then the signal strength value is less than the second threshold value, and at this time, the control display screen is turned on.

It can be seen from the above that the display screen state control device provided by the embodiment of the present invention obtains the basic signal strength value through the first acquisition module 601; the second acquisition module 602 acquires the threshold adjustment value of the proximity sensor according to the environmental state of the terminal; the determination module 603 Determine the threshold of the proximity sensor according to the basic signal strength value and the threshold adjustment value; the control module 604 controls the state of the display screen according to the threshold and the signal strength value detected by the proximity sensor. This solution obtains the threshold adjustment value of the proximity sensor according to the environmental state of the terminal, and then determines the threshold value of the proximity sensor. Therefore, when the terminal is in different environmental states, the threshold value of the proximity sensor is different, so that the state control of the terminal display screen is consistent with that of the terminal. The state of the environment in which the terminal is located can be adapted, so that the accuracy of the state control of the display screen can be improved, thereby improving the stability of the terminal.
