Description

Display state control method and device

technical field

The present invention relates to the technical field of terminals, and in particular, to a display screen state control method and device.

Background technique

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

Currently, judging the proximity or distance between a smart terminal and an external object to control the smart terminal to turn off or brighten the screen is a necessary function in the smart terminal. A smart terminal usually uses an infrared transmitter and an infrared receiver to detect the proximity state or the distance state between the smart terminal and an external object. The infrared transmitter emits infrared light, which is reflected by the obstacle to form a reflected light. After receiving the reflected light, the infrared receiver determines whether the smart terminal is close to or away from the obstacle according to the intensity of the reflected light.

In actual use, part of the infrared rays emitted by the infrared transmitter will directly enter the infrared receiver through diffraction inside the smart terminal, so that the signal detected by the infrared receiver has a certain basic value.

However, due to errors generated in the production process of the smart terminals, the basic values of the signals detected by the infrared receivers of different smart terminals are not all the same. Therefore, for different smart terminals, it is determined that the distance from the obstacle is different. That is, some smart terminals judge that they are in a state of proximity or distance from the obstacle at a relatively long distance, so as to control the smart terminal to turn off or brighten the screen; The obstructions are in a state of approaching or away from each other, thereby controlling the smart terminal to turn off or brighten the screen. As a result, the screen-off and screen-on controls of the smart terminal are inaccurate.

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

The mobile terminal 1000 includes a panel assembly 100 and a housing 200 . The panel assembly 100 is disposed on and connected to the housing 200 . It can be understood that the mobile terminal 1000 may further 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. Display area 100a. The display area 100b of the panel assembly 100 can be used to display images or be used for user touch manipulation and the like.

The panel assembly 100 may be a touch panel assembly, a panel assembly, or a mobile terminal panel assembly having other functions, and so on.

Please refer to FIG. 2 . FIG. 2 is a schematic diagram of the first structure of the panel assembly 100 according to the embodiment of the present invention. The panel assembly 100 includes a sensor module 11 , a cover plate 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 and the cover assembly 12 are spaced apart. The control circuit 13 is connected in communication with the sensor module 11 and the cover plate assembly 12 . In this embodiment, the control circuit 13 is a mainboard, and the sensor module 11 is fixedly arranged on the mainboard.

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 to transmit signals to the outside. The signal receiver 112 and the signal receiver 113 are used to receive signals reflected by external objects.

In some embodiments, the sensor module 11 may 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 may be acoustic wave signals such as ultrasonic waves. The following only takes the signal as an optical signal, the signal transmitter as an optical transmitter, and the signal receiver as an optical receiver for illustration.

In some embodiments, the first light emitter 111 is used for emitting probe light with a wavelength greater than 850 nm, 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 a low beam signal formed after the detection light is reflected by the blocking object 70 . The barrier 70 is generally a human face, and is applied to a scenario when the mobile terminal approaches or moves away from the face during the user's call.

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

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

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

In this embodiment, the first optical transmitter 111 and the first optical receiver 112 may be integrated in a first integrated chip to form a two-in-one chip. Of course, it can also be separated into two independent chips.

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

The first adhesion layer 122 and the second adhesion layer 123 are arranged to achieve the effect of hiding the internal structural components of the mobile terminal 1000 and the second adhesion layer 123 . Even if the user observes the outer side of the cover plate 121, only the first adhesive layer 122 can be seen, but the second adhesive layer 123 cannot be seen.

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 a material 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 of the light. The transmittance of the ink layer can be set according to actual needs. Generally, the transmittance of visible light (such as visible light with a wavelength of 550 nm) of the light-transmitting ink layer 122 is between 2% and 10%, and the optical signal of the proximity sensor (such as a wavelength of 850nm infrared) transmittance is 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 white ink. Of course, the white ink is only an example, and the transparent 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 of the mobile terminal 1000 is also different. For example, when the light-transmitting ink layer 122 is white ink, the appearance of the mobile terminal 1000 is white, that is, the mobile terminal 1000 is a white model. When the light-transmitting ink layer 122 is golden ink, the appearance of the mobile terminal 1000 is golden, that is, the mobile terminal 1000 is a golden model.

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

The light-transmitting ink layer 122 covers the first region on the light-shielding ink layer 123 .

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

In some embodiments, the light-shielding ink layer 123 is provided with a first light-passing hole 124 and a second light-passing hole 125 . The first light-passing hole 124 and the second light-passing hole 125 are used to transmit light. The first light-passing holes 124 and the second light-passing holes 125 form the first area, and the area outside the first light-passing holes 124 and the second light-passing holes 125 on the light-shielding ink layer 123 is the second area. It can be understood that the first light-transmitting holes 124 and the second light-transmitting holes 125 may also be filled with light-transmitting material, and the color of the light-transmitting material may be the same as the color of the light-transmitting ink layer 122 . Wherein, the first light-transmitting hole 124 may include a separate first light-emitting hole 1241 and a first light-receiving hole 1242 . The first light emitter 111 is opposite to the first light emission hole 1241 , and emits detection light outward through the first light emission 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 .

The shapes of the first light-emitting hole 1241 , the first light-receiving hole 1242 and the second light-transmitting hole 125 can be set according to actual needs. For example, it can be in the shape of a circle, a rectangle, a rounded rectangle, and 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 passing 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 emitting hole 1241 .

It can be understood that, as shown in FIG. 3 , in other embodiments, the first light-passing hole 124 may also be a larger hole, which supplies the first optical transmitter 111 and the first optical receiver 112 at the same time. use.

In this embodiment, the control circuit 13 is communicatively connected to the first optical transmitter 111 , the first optical receiver 112 and the second optical receiver 113 , and the first optical transmitter 111 , the first optical receiver 112 and the The second optical receivers 113 are all fixed on the main board.

For example, when the panel assembly 100 is applied to a mobile phone, since the distances between the first optical receiver 112 and the second optical receiver 113 are different from the first optical transmitter 111, the first optical receiver 112 is closer to the For the first light emitter 111, when the panel assembly 100 is closer to the barrier, the second light receiver 113 receives little light due to the long 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, the reflected light is weak, and 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 light. The basic value of the light intensity value is larger, and the cover plate is far away from the barrier, and the light intensity value of the reflected light is small, so the reflected light received by the first light receiver does not change significantly to the detected light intensity. . The distance between the second optical receiver 113 and the first optical transmitter 111 is farther than that of the first optical receiver 112 , so the light emitted by the first optical transmitter 111 is internally reflected into the second optical receiver 113 There are fewer parts, and the basic light intensity value thereof is small, and the light intensity change is relatively large after the reflected light enters the second light receiver 113 after reflection.

During the call of the mobile terminal, the control circuit 13 controls the first optical transmitter 111 to emit detection light, and determines the installation according to the light intensity values of the reflected light received by the first optical receiver 112 and the second optical receiver 113 Whether the mobile terminal with the panel assembly 100 is close to or far from the face. When it is judged that it is far away from the face, the screen of the cover assembly 12 is controlled to turn on, and when it is judged that it is 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 optical receiver 113 reaches the first proximity threshold or the light intensity value received by the second optical receiver 113 reaches the second proximity threshold, it is determined that the mobile terminal is close to the face. When the light intensity value received by the first optical receiver 113 reaches the first distance threshold and the light intensity value received by the second optical receiver 113 reaches the second distance threshold, it is determined that the mobile terminal is away from the face.

Referring to FIG. 4 , FIG. 4 is another schematic structural diagram of the panel assembly 100 in the embodiment of the present invention. The panel assembly 100 includes a sensor module 21 , a cover plate 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 and the cover assembly 22 are spaced apart. The control circuit 23 is connected in communication with the sensor module 21 and the cover plate assembly 22 . In this embodiment, the control circuit 23 is a mainboard, and the sensor module 21 is fixedly arranged on the mainboard.

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 further 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 for emitting invisible light with a wavelength greater than 850 nm, 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 configured to receive a low beam signal formed after the detection light is reflected by the barrier. The second light receiver 214 is used to receive the high beam signal formed after the detection light is reflected by the blocking object. The distance between the first optical receiver 212 and the first optical transmitter 211 is smaller than the distance between the second optical receiver 213 and the first optical transmitter 211 . Wherein, the low beam signal indicates that the incident light receiver after being reflected by the barrier is relatively close to the first light transmitter 211 , and the high beam signal indicates that the incident light receiver after being reflected by the barrier is far from the first light transmitter 211 . The first light emitter 211 is far away.

The distance between the first optical receiver 212 and the first optical transmitter 211 is smaller than the distance between the second optical receiver 213 and the first optical transmitter 211 . Therefore, when the first light emitter 211 is used as the detection light emitter, and when the panel assembly 100 is far away from the obstruction, the second light receiver is more sensitive to detect changes in light intensity; when the panel assembly 100 The light intensity change detection of the first light receiver is more sensitive when it is closer to the obstacle. When the second light emitter 214 is used as the sender of detection light, and when the panel assembly 100 is far away from the obstruction, the light intensity change detection of the second light receiver 214 is more sensitive; when the panel assembly 100 is far away from the obstruction When the obstruction is closer, the detection of the light intensity change of the first light receiver 212 is more sensitive.

In this embodiment, the control circuit 23 can select one of the first light emitter 211 and the second light emitter 214 as the probe light emitter. Normally, the first light emitter 211 is used as the probe 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 sender of the detection light.

In some embodiments, the first light transmitter 211 , the first light receiver 212 and the first ambient brightness sensor 215 may 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 can 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 transmitter 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 may be arranged on the circuit board.

The optical transmitter 211 and the first optical 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 2-in-1 chips is between 2 mm and 12 mm. The distance is the distance between the geometric centers of the two 2-in-1 chips.

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

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 is formed by spraying or printing with white ink. Of course, the white ink is only an example, and the transparent ink layer 222 can also be designed in other colors according to different aesthetic requirements.

The light-shielding ink layer 223 may be formed by spraying or printing with black ink. The light-shielding ink layer 223 is provided with a first light-passing hole 224 and a second light-passing hole 225 .

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

Wherein, the first light-transmitting hole 224 may include a separate first light-emitting hole 2241 and a first light-receiving hole 2242 . The first light emitter 211 is opposite to the first light emission hole 2241 , and emits detection light outward through the first light emission hole 2241 . The first light receiver 212 and the first ambient 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 , and the first environment The brightness sensor 215 detects the ambient light intensity through the first light receiving hole 2242 .

The second light-transmitting hole 225 may include separate second light-emitting holes 2251 and second light-receiving holes 2252 . The second light emitter 214 is opposite to the second light emission hole 2251 , and emits detection light outward through the second light emission hole 2251 . The second light receiving hole 2252 is opposite to the second light receiver 213 and the second ambient 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 ambient light The brightness sensor 216 detects the ambient light intensity through the second light receiving hole 2252 .

It can be understood that, as shown in FIG. 6 , in other embodiments, the first light-passing hole 224 may also be a larger hole, which is used for the first light transmitter 211 and the first light receiver 212 at the same time. And the first ambient brightness sensor 215 is used.

The second light-passing hole 225 can also be a larger hole, which is used by the second light transmitter 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, under normal circumstances, the control circuit 23 selects the first light emitter 211 as the sender of detection light, and the second light emitter 214 does not work.

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

Wherein, the transparent ink layer 222 may be formed by spraying or printing with 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 most infrared rays can be transmitted. The appearance of IR ink appears as black ink.

Wherein, a functional area may 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 in the functional area. This functional area is used to pass ambient light so that the ambient brightness sensor 216 detects the ambient brightness.

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

The following only takes the sensor module including a signal transmitter and a signal receiver as an example to describe the display screen state control method.

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 received by the signal receiver when the 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 signal transmitter can transmit a detection signal to the outside. At this time, there is no object blocking the side of the terminal display screen. The signal emitted by the signal transmitter to the outside is not reflected by the object. At this time, part of the signal transmitted by the signal transmitter enters the signal receiver directly through diffraction inside the terminal. The signal received by the signal receiver is all from the diffraction inside the terminal, so the signal strength received by the signal receiver is at the minimum value. The signal strength value at this time can be used as the signal strength basic value.

In some embodiments, after the terminal is powered on, the signal strength values received by the signal receiver may be acquired multiple times, and the smallest one is taken as the basic signal strength value.

S520: Determine a signal strength threshold corresponding to the terminal according to the basic signal strength value.

The signal strength threshold is used to determine whether the terminal and the external object are in a close state or a distance state, so as to control the display screen of the terminal to be turned off or turned on. In practical applications, after acquiring the basic signal strength value, the terminal may determine the signal strength threshold corresponding to the terminal according to the basic signal strength value.

In some embodiments, as shown in FIG. 9 , determining the signal strength threshold corresponding to the terminal according to the signal strength basic value may include the following steps:

S521, determine the interval in which the signal strength basic value is located;

S522: Determine a signal strength threshold corresponding to the terminal according to the interval.

In practical applications, the basic value of the signal strength may be divided into multiple intervals in advance, and the information of the multiple intervals may be stored in the terminal. For example, in the case where the signal receiver is a 10-bit receiver chip (10-bit receiver chip, the range of the signal receiver is 1024), the basic value of the signal strength can be divided into (0, 100], (100, 400], ( 400, 1000] and other three intervals.

After acquiring the basic signal strength value, the terminal determines which interval the basic signal strength value is in. For example, if the acquired basic signal strength value is 300, it can be determined that the basic signal strength value is in the interval of (100, 400).

Different terminals may have different signal strength thresholds. In this way, the terminal can more accurately judge whether it is in a state of approaching or away from an external object according to the signal strength threshold, so as to more accurately control the display screen of the terminal to be turned off or turned on. After determining the interval in which the basic signal strength value is located, the terminal may determine the corresponding signal strength threshold according to the interval.

In practical applications, for models with different panel colors, different colors of ink are applied on the cover assembly at the position opposite to the signal transmitter and the signal receiver. The transmittance of different colors of ink to the signal is different. Therefore, the amount of signal diffracted inside the terminal to directly enter the signal receiver is different. Therefore, the above-mentioned multiple sections may correspond to models with different panel colors. For example, the signal strength basic value interval (0, 100) can correspond to the black model; the signal strength basic value interval (100, 400) can correspond to the gold model; the signal strength basic value interval (400, 1000] can correspond to the white model model.

When the basic value of the signal strength acquired by the terminal is in the (0, 100] interval, it can be considered that the current terminal is a black model. When the basic value of the signal strength acquired by the terminal is in the (100, 400] interval, it can be considered that the current terminal is Gold model. When the basic value of the signal strength obtained by the terminal is in the range of (400, 1000], it can be considered that the current terminal is a white model.

In some embodiments, as shown in FIG. 10 , determining the signal strength threshold corresponding to the terminal according to the interval may include the following steps:

S5221, obtaining a signal strength adjustment amount according to the interval and a preset mapping relationship, where the preset mapping relationship is a mapping relationship between the interval and the signal strength adjustment amount;

S5222: Determine a signal strength threshold according to the signal strength basic value and the signal strength adjustment amount.

The signal strength adjustment amount is used to adjust the signal strength basic value, thereby generating a signal strength threshold. The signal strength adjustment amount can be a signal strength value. For example, the signal strength adjustment amount may be 80. The signal strength adjustment amount can also be a ratio. For example, the signal strength adjustment is 20%.

In practical applications, the mapping relationship between the interval and the signal strength adjustment amount may be preset, and the mapping relationship may be stored in the terminal. For example, the preset mapping relationship may be the mapping relationship shown in Table 1.

interval Signal strength adjustment amount (0, 100] (100, 400] 60 (400, 1000]

Table 1

After determining the interval in which the basic signal strength value is located, the terminal obtains the signal strength adjustment amount according to the interval and the preset mapping relationship. Then, a signal strength threshold is determined according to the signal strength base value and the signal strength adjustment amount.

When the signal strength adjustment amount is a numerical value, the numerical value can be added to the base signal strength value as the signal strength threshold. For example, if the basic signal strength value is 300, the interval in which the basic signal strength value is located is (100, 400], and the acquired signal strength adjustment amount is 60, the signal strength threshold value can be determined to be 360.

When the signal strength adjustment amount is a ratio, the signal strength corresponding to the ratio can be added to the basic value of the signal strength as the signal strength threshold. For example, if the basic value of the signal strength is 300, and the obtained ratio is 20%, the signal strength threshold value may also be determined to be 360 at this time.

Continue to refer to FIG. 8 below.

S530: Acquire the signal strength value received by the signal receiver.

In practical applications, after the terminal determines the signal strength threshold, it can continuously obtain the signal strength value through the signal receiver when the state of the display screen needs to be controlled. At this time, the side of the terminal display screen may or may not be blocked by an object. For example, when the terminal is in a call state, the signal strength value is continuously obtained.

S540, control the state of the display screen according to the signal strength threshold and the signal strength value.

The states of the display screen include off and on, that is, off and on. After acquiring the signal strength value, the terminal compares the signal strength value with the signal strength threshold value to determine the magnitude relationship between the signal strength value and the signal strength threshold value, so as to control the state of the display screen.

In some embodiments, as shown in FIG. 9 , the signal strength threshold includes a first threshold, and controlling the state of the display screen according to the signal strength threshold and the signal strength value may include the following steps:

S541, when the display screen is in a bright screen state, determine whether the signal strength value 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 signal strength 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 signal strength value is obtained, the signal strength value is compared with the first threshold value to determine whether the signal strength value is greater than the first threshold value. When it is determined that the signal strength value is greater than the first threshold, it indicates that the terminal is in a proximity state with an external object (for example, a user's face), and at this time, the display screen is controlled to be off.

For example, if the first threshold value is 400 and the acquired signal strength value is 500, then the signal strength value is greater than the first threshold value, and the display screen is controlled to turn off at this time.

In some embodiments, as shown in FIG. 11 , the signal strength threshold includes a second threshold, and controlling the state of the display screen according to the signal strength threshold and the signal strength value may include the following steps:

S543, when the display screen is in a screen-off state, determine whether the signal strength value 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 signal strength 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 light up when the display is off. For the same terminal, the low threshold is smaller than the above-mentioned high threshold.

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

For example, if the second threshold is 300 and the acquired signal strength value is 200, then the signal strength value is smaller than the second threshold value, and the display screen is controlled to light up at this time.

As can be seen from the above, the display screen state control method provided by the embodiment of the present invention obtains the basic value of signal strength; determines the signal strength threshold corresponding to the terminal according to the basic signal strength value; obtains the signal strength value received by the signal receiver; The signal strength threshold and this signal strength value control the state of the display. The scheme determines the corresponding signal strength threshold according to the signal strength basic value obtained by the terminal, so that a specific signal strength threshold can be determined for each terminal, and then the state of the display screen is controlled according to the signal strength threshold and the signal strength value. It can avoid that the signal strength threshold value does not match the signal strength value range actually received by the terminal, thereby improving the accuracy of the display screen state control.

The embodiment of the present 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 between the terminal and the external object. The distance state includes a far state and a close state. The status of the display includes on and off.

As shown in FIG. 12 , the display screen state control apparatus 600 includes: an acquisition module 601 , a determination module 602 , and a control module 603 .

The obtaining module 601 is configured to obtain a basic signal strength value, where the basic signal strength value is a signal strength value received by the signal receiver when the 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 signal transmitter may transmit a detection signal to the outside, and the acquisition module 601 acquires the signal strength value at this time through the signal receiver. At this time, there is no object blocking the side of the terminal display screen. The signal emitted by the signal transmitter to the outside is not reflected by the object. At this time, part of the signal transmitted by the signal transmitter enters the signal receiver directly through diffraction inside the terminal. The signal received by the signal receiver is all from the diffraction inside the terminal, so the signal strength received by the signal receiver is at the minimum value. The signal strength value at this time can be used as the signal strength basic value.

In some embodiments, after the terminal is turned on and running, the acquiring module 601 may acquire the signal strength values received by the signal receiver multiple times, and take the smallest one as the basic signal strength value.

The determining module 602 is configured to determine a signal strength threshold corresponding to the terminal according to the basic signal strength value.

The signal strength threshold is used to determine whether the terminal and the external object are in a close state or a distance state, so as to control the display screen of the terminal to be turned off or turned on. In practical applications, after the obtaining module 601 obtains the basic signal strength value, the determining module 602 may determine the signal strength threshold corresponding to the terminal according to the basic signal strength value.

In some embodiments, as shown in FIG. 13 , the determination module 602 includes: a first determination sub-module 6021 and a second determination sub-module 6022 .

The first determination sub-module 6021 is used to determine the interval in which the basic value of the signal strength is located;

The second determining submodule 6022 is configured to determine the signal strength threshold corresponding to the terminal according to the interval.

In practical applications, the basic value of the signal strength may be divided into multiple intervals in advance, and the information of the multiple intervals may be stored in the terminal. For example, in the case where the signal receiver is a 10-bit receiver chip (10-bit receiver chip, the range of the signal receiver is 1024), the basic value of the signal strength can be divided into (0, 100], (100, 400], ( 400, 1000] and other three intervals.

After the acquisition module 601 acquires the basic signal strength value, the first determination sub-module 6021 determines which interval the basic signal strength value is in. For example, if the acquired basic signal strength value is 300, it can be determined that the basic signal strength value is in the interval of (100, 400).

Different terminals may have different signal strength thresholds. In this way, the terminal can more accurately judge whether it is in a state of approaching or away from an external object according to the signal strength threshold, so as to more accurately control the display screen of the terminal to be turned off or turned on. After the first determination sub-module 6021 determines the interval in which the basic signal strength value is located, the second determination sub-module 6022 may determine the corresponding signal strength threshold according to the interval.

In practical applications, for models with different panel colors, different colors of ink are applied on the cover assembly at the position opposite to the signal transmitter and the signal receiver. The transmittance of different colors of ink to the signal is different. Therefore, the amount of signal diffracted inside the terminal to directly enter the signal receiver is different. Therefore, the above-mentioned multiple sections may correspond to models with different panel colors. For example, the signal strength basic value interval (0, 100) can correspond to the black model; the signal strength basic value interval (100, 400) can correspond to the gold model; the signal strength basic value interval (400, 1000] can correspond to the white model model.

When the acquired signal strength basic value is in the (0, 100] interval, it can be considered that the current terminal is a black model. When the acquired signal strength basic value is in the (100, 400] interval, it can be considered that the current terminal is a golden phone. When the acquired basic signal strength value is in the interval of (400, 1000], it can be considered that the current terminal is a white model.

In some embodiments, the second determination sub-module 6022 is configured to perform the following steps:

Obtain the signal strength adjustment amount according to the interval and a preset mapping relationship, where the preset mapping relationship is a mapping relationship between the interval and the signal strength adjustment amount;

The signal strength threshold is determined according to the signal strength base value and the signal strength adjustment amount.

The signal strength adjustment amount is used to adjust the signal strength basic value, thereby generating a signal strength threshold. The signal strength adjustment amount can be a signal strength value. For example, the signal strength adjustment amount may be 80. The signal strength adjustment amount can also be a ratio. For example, the signal strength adjustment is 20%.

In practical applications, the mapping relationship between the interval and the signal strength adjustment amount may be preset, and the mapping relationship may be stored in the terminal. For example, the preset mapping relationship may be the mapping relationship shown in Table 2.

interval Signal strength adjustment amount (0, 100] 10% (100, 400] 20% (400, 1000] 30%

Table 2

After the first determination sub-module 6021 determines the interval in which the basic value of the signal strength is located, the second determination sub-module 6022 obtains the signal strength adjustment amount according to the interval and the preset mapping relationship. Subsequently, the second determination sub-module 6022 determines the signal strength threshold according to the signal strength basic value and the signal strength adjustment amount.

When the signal strength adjustment amount is a ratio, the signal strength corresponding to the ratio can be added to the basic value of the signal strength as the signal strength threshold. For example, if the basic signal strength value is 300, the interval in which the basic signal strength value is located is (100, 400], and the acquired signal strength adjustment amount is 20%, the signal strength threshold value can be determined to be 360.

When the signal strength adjustment amount is a numerical value, the numerical value can be added to the base signal strength value as the signal strength threshold. For example, if the basic signal strength value is 300, the interval in which the basic signal strength value is located is (100, 400], and the obtained signal strength adjustment amount is 60, the signal strength threshold value may also be determined to be 360.

The obtaining module 601 is further configured to obtain the signal strength value received by the signal receiver.

In practical applications, after the determination module 602 determines the signal strength threshold, the acquisition module 601 can continuously acquire the signal strength value through the signal receiver when the state of the display screen needs to be controlled. At this time, the side of the terminal display screen may or may not be blocked by an object. For example, when the terminal is in a call state, the obtaining module 601 continuously obtains the signal strength value.

The control module 603 is configured to control the state of the display screen according to the signal strength threshold and the signal strength value.

The states of the display screen include off and on, that is, off and on. After the acquisition module 601 acquires the signal strength value, the control module 603 compares the signal strength value with the signal strength threshold value to determine the magnitude relationship between the signal strength value and the signal strength threshold value, thereby controlling the state of the display screen.

In some embodiments, the signal strength threshold includes a first threshold, and the control module 603 is configured to perform the following steps:

When the display screen is in the bright screen state, determine whether the signal strength value is greater than the first threshold;

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

In practical applications, the signal strength 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 on, after the acquisition module 601 acquires the signal strength value, the control module 603 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 proximity state with an external object (for example, a user's face), and at this time, the display screen is controlled to be off.

For example, if the first threshold value determined by the determining module 602 is 400, and the signal strength value obtained by the acquiring module 601 is 500, then the signal strength value is greater than the first threshold value, and the control module 603 controls the display screen to turn off.

In some embodiments, the signal strength threshold includes a second threshold, and the control module 603 is configured to perform the following steps:

When the display screen is in the off-screen state, determine whether the signal strength value 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 signal strength 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 light up when the display is off. For the same terminal, the low threshold is smaller than the above-mentioned high threshold.

When the display screen of the terminal is in a screen-off state, after the acquisition module 601 acquires the signal strength value, the control module 603 compares the signal strength value with the second threshold to determine whether the signal strength value is less 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 far away state from an external object (for example, a user's face), and at this time, the display screen is controlled to light up.

For example, if the second threshold value determined by the determining module 602 is 300, and the signal strength value obtained by the acquiring module 601 is 200, then the signal strength value is less than the second threshold value, and the control module 603 controls the display screen to light up.

As can be seen from the above, in the display screen state control device provided by the embodiment of the present invention, the basic value of signal strength is obtained through the acquisition module 601; the determination module 602 determines the signal strength threshold corresponding to the terminal according to the basic value of signal strength; The signal strength value received by the monitor; the control module 603 controls the state of the display screen according to the signal strength threshold value and the signal strength value. In this solution, the corresponding signal strength threshold is determined according to the basic signal strength value obtained by the acquisition module 601, so that a specific signal strength threshold can be determined for each terminal, and then the display screen is controlled according to the signal strength threshold and the signal strength value. state, which can avoid mismatch between the signal strength threshold and the range of signal strength values actually received by the terminal, thereby improving the accuracy of display state control.
