Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Electronic devices, such as mobile phones or tablet computers, are generally equipped with a light sensor to detect the light intensity of the environment where the electronic device is located, so as to automatically adjust the brightness of the screen. Taking a mobile phone as an example, an optical sensor is disposed in an upper region of the mobile phone. When the user is under the sun or in a dark environment, the light sensor feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions, such as increasing or decreasing the light brightness of the display screen assembly. In the related art, the electronic device is provided with the optical sensor, and the housing is required to be provided with corresponding holes for receiving the optical signal, but with the development of the electronic device, the requirements of people on the appearance and the operation experience of the mobile phone are higher and higher. The mobile phone has been developed towards the direction of the full-screen, and the full-screen mobile phone forms an ultra-narrow frame between the casing and the display screen assembly, and because the width of the ultra-narrow frame is too small, the ultra-narrow frame may not have enough space to open a hole, so that the overall strength of the frame is reduced even if the hole is opened, and further the reliability of the electronic equipment is low.

Referring to fig. 1 and 2, an electronic device according to an embodiment of the present invention may be a mobile phone or a tablet computer. The electronic device according to the embodiment of the present invention is described by taking a mobile phone as an example, but it is to be understood that the specific form of the electronic device 100 may be other, and is not limited herein.

Referring to fig. 3, the electronic device 100 includes a display 13, an infrared sensor 16, and a light blocking member 30. The display 13 includes a display area 1311 and a non-display area 1312, and the non-display area 1312 surrounds the display area 1311. The infrared sensor 16 is located below the display 13 and includes an emitter 161 and a receiver 162, the emitter 161 being configured to emit infrared light, for example, the emitter 161 emitting infrared light through the non-display area 1312. The receiver 162 is used for receiving infrared light, for example, the receiver 162 receives infrared light through the display region 1311. The light blocking member 30 is disposed between the emitter 161 and the display region 1311, and the light blocking member 30 is used to block infrared light emitted from the emitter 161 from entering the display region 1311.

It is understood that the display 13 includes an upper surface 131 and a lower surface 132, and that the display 13 is adapted to emit light for display through the upper surface 131. The display 13 is transparent so that infrared light from the emitter 161 is transmitted through the display 13 and, similarly, reflected infrared light is received by the receiver 162 through the display 13.

The transmitter 161 is used for transmitting infrared light, when the transmitted infrared light meets an obstacle in the detection direction, a part of the infrared light is reflected back to be received by the receiver 162, and the processor calculates the time from the transmission of the infrared light to the reflection of the infrared light, so that the distance between the electronic device 100 and the obstacle can be determined and corresponding adjustment can be made. In one example, when the user is answering or making a call, the electronic device 100 is close to the head, the transmitter 161 emits infrared light, the receiver 162 receives the infrared light reflected back by the head, the processor calculates the time from emission to reflection of the infrared light, and sends a corresponding instruction to control the screen to close the background light, and when the electronic device 100 is far away from the head, the processor calculates again according to the data fed back and sends an instruction to re-open the screen background light. Therefore, misoperation of the user is prevented, and the electric quantity of the mobile phone is saved.

Since the emitter 161 has a certain emission angle, even if the emitter 161 is located outside the display area 1311, there is no guarantee that infrared light emitted by the emitter 161 cannot enter the display area 1311. Therefore, the light blocking element 30 blocks the infrared light emitted by the emitter 161 from entering the display region 1311, and prevents the infrared light from adversely affecting the optoelectronic elements in the display region 1311. In one example, the light blocking member 30 is foam. Of course, the light blocking member 30 may be other non-light transmissive materials such as plastic.

In the electronic device 100, the receiver 162 serves as an input element of the electronic device 100, and the receiver 162 can receive an infrared signal and input the signal into the electronic device 100. The display 13 serves as an output element of the electronic device 100, and the display 13 can output display contents to the outside of the display 13 for a user to obtain corresponding information.

The housing 20 is used for accommodating the electronic device 100 to protect the electronic device 100. The casing 20 encloses the electronic device 100 by disposing the electronic device 100 in the casing 20, so as to prevent external factors from directly damaging the internal components of the electronic device 100. The housing 20 may be formed by CNC machining of an aluminum alloy, or may be injection molded using Polycarbonate (PC) or PC + ABS material.

In summary, in the electronic device 100 according to the embodiment of the invention, the display 13 enables the infrared sensor 16 to be disposed below the display 13 to ensure that the electronic device 100 achieves a full-screen effect, and in addition, the orthographic projection of the emitter 161 of the red light sensor 16 on the lower surface 132 of the display 13 is located outside the display area 1311 and the light blocking element 30 blocks infrared light from entering the display area 1311, so that the infrared light emitted by the emitter 161 can be prevented from affecting the operating stability of the TFT of the display area 1311, and the display 13 and the infrared sensor 16 can achieve respective functions without interfering with each other.

Specifically, the electronic device 100 further includes a battery 110 and a main circuit board 120, the battery 110 and the main circuit board 120 are both disposed on the same side of the casing 20, and the battery 110 and the display 13 are disposed on opposite sides of the casing 20. The battery 110 is used for supplying power to the electronic device 100, and the main circuit board 120 is configured to control an operating state of the electronic device 100, for example, the main circuit board 120 controls the display 13 to play video content.

In some embodiments, the display 13 comprises an OLED display.

In particular, an Organic Light-Emitting Diode (OLED) display screen has good Light transmittance and can transmit visible Light and infrared Light. Therefore, the OLED display screen does not influence the infrared sensor to emit and receive infrared light under the condition of showing the content effect. The display screen 13 may also be a Micro LED display screen, which also has good transmittance for visible light and infrared light. Of course, these display screens are merely exemplary and embodiments of the present invention are not limited in this respect.

Referring to fig. 4, in some embodiments, the light blocking member 30 is adhered and fixed at the connection between the display region 1311 and the non-display region 1312. In this way, the fixing manner of the light blocking member 30 is easily achieved, so that the electronic device 100 is easily manufactured. In one example, when the light blocking member 30 is fixed to the lower surface 132 of the display 13, a double-sided adhesive tape may be attached to one surface of the light blocking member 30, and then the light blocking member 30 may be fixedly attached to the joint between the display region 1311 and the non-display region 1312 by the double-sided adhesive tape.

Referring to fig. 3, in some embodiments, the infrared sensor 16 includes a package 163 for packaging the emitter 161 and the receiver 162, and the light blocking member 30 is fixed on the package 163 and located between the emitter 161 and the receiver 162. In this manner, the light blocking member 30 is fixedly installed, so that the infrared sensor 16 and the light blocking member 30 are fitted with the display screen 13 as a whole.

In some embodiments, the light blocking member 30 is a soft material, and the light blocking member 30 abuts the lower surface 132. Thus, the light blocking element 30 has a better light blocking effect, and ensures that the infrared light emitted by the emitter 161 cannot enter the display region 1311. In addition, the matching structure of the infrared sensor 16 and the display screen 13 is more compact.

Referring to fig. 5, in some embodiments, the light blocking member 30 and the package 163 are an integral structure. In this way, the material of the light blocking member 30 is consistent with the material of the package body 163, and the light blocking member 30 can be formed at the same time of manufacturing the infrared sensor 16, so that the number of parts of the electronic device 100 can be saved to improve the assembly efficiency of the electronic device 100.

In some embodiments, the front projection of the receiver 162 on the lower surface 132 is located within the display area 1311, and the receiver 162 is configured to receive infrared light transmitted through the display area 1311. In this manner, the receiver 162 has a sufficient spatial arrangement. Of course, in some embodiments, the orthographic projection of receiver 162 on lower surface 132 may also be located at a position corresponding to non-display region 1312, as shown in fig. 6.

Referring to fig. 3, in some embodiments, the electronic device 100 further includes a touch layer 12 and a cover plate 11. The cover plate 11 is formed on the touch layer 12, the touch layer 12 is disposed on the display 13, the upper surface 131 of the display 13 faces the touch layer 12, and the light transmittance of the touch layer 12 and the cover plate 11 to visible light and the light transmittance of infrared light are both greater than 90%.

Specifically, the touch layer 12 is mainly used for receiving an input signal generated when a user touches the touch layer 12 and transmitting the input signal to the circuit board for data processing, so as to obtain a specific position where the user touches the touch layer 12. The touch layer 12 and the display screen 13 can be attached by adopting an In-Cell or On-Cell attaching technology, so that the weight of the display screen can be effectively reduced, and the overall thickness of the display screen can be reduced. In addition, the cover plate 11 is disposed on the touch layer 12, so that the touch layer 12 and the internal structure thereof can be effectively protected, and the touch layer 12 and the display screen 13 are prevented from being damaged by external force. The light transmittance of the cover plate 11 and the light transmittance of the touch layer 12 to visible light and infrared light are both greater than 90%, which is not only beneficial to the display screen 13 to better display the content effect, but also beneficial to the infrared sensor 16 arranged below the display screen 13 to stably emit and receive infrared light, and ensures the normal operation of the infrared sensor 16.

In some embodiments, the display 13 is used for displaying light through the display area 1311, and the ratio of the area of the display area 1311 to the area of the cover 11 is greater than 90%. For example, the ratio of the area of the display region 1311 to the area of the cover plate 11 is a ratio of 95%, 96%, or the like.

Specifically, by setting the proportion of the display area 1311 and the cover plate 11, after the display screen 13 is attached to the cover plate 11, the display area 1311 can display the content effect in a large size area, so that not only is good user experience improved, but also the screen occupation ratio of the electronic device 100 is effectively increased, and a comprehensive screen effect is achieved. The non-display area 1312 can also be used to shield other components and metal traces underneath the display 13 to maintain the appearance of the product consistent. The non-display area 1312 may be printed with ink to increase the optical density of the display 13, so as to ensure the light-shielding effect and provide a good visual effect.

Referring to fig. 3, in some embodiments, the electronic device 100 further includes a first coating layer 14, the first coating layer 14 is coated on the bottom surface 132 and covers the emitter 161, the first coating layer 14 is used for transmitting infrared light and intercepting visible light, and the emitter 161 is used for transmitting infrared light through the first coating layer 14.

Specifically, the emitter 161 is usually mounted with a gap during the process of assembly, which results in a gap between the emitter 161 and other components, and visible light enters the gap to leak light. Therefore, in the direction in which the emitter 161 and the display 13 are stacked, the orthographic projection area of the first coating layer 14 on the lower surface 132 covers the orthographic projection area of the emitter 161 on the lower surface 132, so that the emitter 161 can be sufficiently shielded by the first coating layer 14 without affecting the normal operation of the emitter 161, and the effect that the emitter 161 is not visible when the electronic device 100 is viewed from the outside is achieved.

The first coating layer 14 transmits infrared light, so that when the transmitter 161 transmits infrared light outwards for detection, the intensity of the infrared light transmitted through the first coating layer 14 is attenuated to a small extent, or the attenuation degree does not affect the detection process, thereby ensuring the normal operation of the transmitter 161. The first coating layer 14 blocks visible light, so that the visible light cannot pass through the first coating layer 14, and the emitter 161 is visually shielded, thereby achieving the effect that the emitter 161 is not visible when the electronic device 100 is viewed from the outside.

In some embodiments, the infrared sensor 16 includes a proximity sensor, the emitter 161 is configured to emit infrared light through the first coating layer 1311 and the non-display area 1312, and the receiver 162 is configured to receive the infrared light reflected by the object to detect a distance of the object from the upper surface 131.

Specifically, in one example, when the user is answering or making a call, the electronic device 100 is close to the head, the emitter 161 emits infrared light, the receiver 162 receives the reflected infrared light, the processor calculates the time from the emission of the infrared light to the reflection of the infrared light, and emits a corresponding instruction to control the screen to close the background light, and when the electronic device 100 is far away from the head, the processor performs calculation again according to the feedback data and emits an instruction to re-open the screen background light. Therefore, misoperation of the user is prevented, and the electric quantity of the mobile phone is saved.

In certain embodiments, the first coating layer 14 comprises an IR ink having a transmittance of greater than 85% for infrared light and a transmittance of less than 6% for visible light, the IR ink being transparent to infrared light at a wavelength of 850nm to 940 nm.

Specifically, since the IR ink has a characteristic of low transmittance to visible light, the emitter 161 disposed under the first coating layer 14 is not observed based on the visual perception of human eyes when the electronic device 100 is viewed from the outside. Meanwhile, the IR printing ink has the characteristic of high light transmittance to infrared light, so that the emitter 161 can stably emit the infrared light, and the normal work of the emitter 161 is ensured.

Referring to fig. 6, in some embodiments, the transmitter 161 and the receiver 162 are separate structures.

In particular, since the transmitter 161 and the receiver 162 are separate structures, a compact arrangement or a dispersed arrangement may be selected when arranging the components, which is not only beneficial for the electronic device 100 to fully allocate the spatial positions of the components and apply the transmitter 161 and the receiver 162 with various shapes, but also beneficial for the transmitter 161 and the receiver 162 to provide possible positions for other components in the electronic device 100.

In one example, the split emitters 161 and receivers 162 are each disposed below a length edge of the non-display area 1312, as shown in fig. 6.

In another example, the split emitters 161 and receivers 162 are each disposed below a corner corresponding position of the non-display area 1312, as shown in fig. 7.

In yet another example, the split emitters 161 and receivers 162 are respectively disposed below both length edges of the non-display area 1312, as shown in fig. 8.

Referring to fig. 9, in some embodiments, the transmitter 161 and the receiver 162 are of unitary construction.

Specifically, the transmitter 161 and the receiver 162 are of an integral structure, so that line connection between split structures can be omitted, the reduction of line process flow is facilitated, the production efficiency of products is improved, and the production cost is reduced.

In the infrared sensor 16, as in the example of fig. 9, the transmitter 161 is located at a position corresponding to the non-display region 1312, and the receiver 162 is located at a position corresponding to the display region 1311.

In the example of fig. 10, the transmitter 161 and the receiver 162 of the entire structure are each disposed at a position corresponding to the width edge of the non-display region 1312.

Referring to fig. 3 again, in some embodiments, the electronic device 100 further includes a second coating layer 15 coated on the bottom surface 132 and covering the receiver 162, wherein the second coating layer 15 is used for transmitting infrared light and intercepting visible light, and the receiver 162 is used for receiving infrared light through the display region 1311 and the second coating layer 15.

Specifically, the receiver 162 is usually mounted with a gap during the process of assembly, which results in a gap between the receiver 162 and other components, so that visible light enters from the gap and light leakage occurs. Therefore, in the direction in which the receiver 162 and the display 13 are stacked, the orthographic projection area of the second coating layer 15 on the lower surface 132 covers the orthographic projection area of the receiver 162 on the lower surface 132, so that the receiver 162 can be sufficiently shielded by the second coating layer 15 without affecting the normal operation of the receiver 162, and the effect that the receiver 162 is not visible when the electronic device 100 is viewed from the outside is achieved.

The second coating layer 15 may also be an IR ink, which has a characteristic of low transmittance of visible light, so that the receiver 162 disposed under the second coating layer 15 is not perceived by the human eye when the electronic device 100 is viewed from the outside. Meanwhile, since the IR ink has a characteristic of high transmittance to infrared light, the receiver 162 can stably receive infrared light, and normal operation of the receiver 162 is ensured.

In some embodiments, electronic device 100 further includes a buffer layer 17 covering lower surface 132 and avoiding infrared sensor 16.

Specifically, the buffer layer 17 is used to buffer impact force and prevent shock so as to protect the touch layer 12, the display screen 13 and the internal structure thereof, and prevent the display screen 13 from being damaged due to external impact. Cushioning layer 17 may be made of foam or rubber or other soft material. Of course, these cushioning materials are merely exemplary and embodiments of the present invention are not limited in this respect. The purpose of avoiding the infrared sensor 16 during the process of providing the buffer layer 17 is to prevent the buffer layer 17 from blocking the signal received by the infrared sensor 16, so that the infrared sensor 16 is not affected during the process of receiving infrared light.

In some embodiments, electronic device 100 further includes a metal layer 18 overlying buffer layer 17 and avoiding infrared sensor 16.

Specifically, the metal layer 18 is used for shielding electromagnetic interference and grounding, and has a function of diffusing temperature rise. The metal layer 18 may be cut out of a metal material such as copper foil or aluminum foil. Of course, these metal materials are merely exemplary and embodiments of the present invention are not limited thereto. In addition, avoiding the infrared sensor 16 during the process of disposing the metal layer 18 is to prevent the metal layer 18 from blocking the signal received by the infrared sensor 16, so that the infrared sensor 16 is not affected during the process of receiving the infrared light.

Referring to fig. 11 and 12, in some embodiments, the electronic device 100 includes a housing 20, a functional device (not shown), and an optical sensor 40 disposed in the housing 20. The housing 20 defines an opening 22. The functional device is disposed in correspondence with the opening 22. The functional device includes at least one of a microphone, a speaker, and a socket. The light sensor 40 is configured to receive light passing through the opening 22.

In the electronic device 100 according to the embodiment of the invention, the opening 22 originally formed in the housing 20 is utilized to enable light to enter the optical sensor 40, so that additional openings are avoided in the display 13 or the electronic device 100, normal operation of the optical sensor 40 is ensured, full screen of the electronic device 100 is facilitated, and user experience can be improved.

It will be appreciated that the electronic device 100 typically has a plurality of openings 22 in the housing 20 to allow the functional components to function properly. In another example, the housing 20 of the electronic device 100 is provided with an opening 22a, and the speaker of the electronic device 100 is disposed corresponding to the opening 22a, so that the speaker operates normally. In yet another example, the housing 20 of the electronic device 100 is provided with an opening 22b, and the microphone of the electronic device 100 is disposed corresponding to the opening 22b, so that the microphone operates normally. In one example, the housing 20 of the electronic device 100 is provided with an opening 22c, and the socket of the electronic device 100 is connected to an external device through the opening 22c, of course, the socket 22c may be a charging socket or an earphone socket, and even the charging socket and the earphone socket may be multiplexed, and in the case that the charging socket and the earphone socket are multiplexed, the charging cable and/or the earphone cable may be adapted to the socket through a patch cord. The opening 22 of the present embodiment includes, but is not limited to, the above.

The electronic device 100 according to the embodiment of the invention utilizes the opening 22 formed in the housing 20 to transmit light to the optical sensor 40, that is, the opening 22 is reused without affecting the original function of the opening 22. In this way, the optical sensor 40 can be disposed inside the housing 20 without requiring a separate opening in the electronic device 100.

In some embodiments, the light-sensing surface 42 of the light sensor 40 faces the aperture 22. In this manner, the light sensor 40 receives light. It will be appreciated that when the photosensitive surface 42 faces away from the opening 22, no light is incident on the photosensitive surface 42 and is sensed by the photosensor 40.

Referring to fig. 13, in some embodiments, the electronic device 100 includes a light guide element 50 disposed in the housing 20 and between the housing 20 and the light sensor 40, wherein the light guide element 50 is used for guiding the light passing through the opening 22 to the light sensor 40. In this manner, the transmission of light to the light sensor 40 is achieved. It will be appreciated that the use of the light guide element 50 to direct light allows the position of the light sensor 40 to be no longer limited by the aperture 22, thereby allowing flexibility in the placement of the light sensor 40. In addition, this also helps to increase flexibility in layout of other components within the electronic device 100.

In some embodiments, the light guide element 50 includes a vertical portion 53 and a horizontal portion 54 connected to the vertical portion 53, the vertical portion 53 faces the opening 22, and the horizontal portion 54 is bent from a bottom end of the vertical portion 53 toward the light sensor 40. In this manner, the light guide element 50 is substantially L-shaped, so that the light sensor 40 is more easily disposed inside the housing 20. Of course, in some embodiments, light guide element 50 may have other shapes such as an arc shape. That is, the specific shape of the light guide element 50 can be designed and selected according to the specific situation of the electronic device 100, and the specific shape and structure of the light guide element 50 are not limited herein, as long as the light passing through the opening 22 is guided to the light sensor 40.

In some embodiments, the light incident direction of the light guide element 50 is perpendicular to the opening 22, and/or the light emergent direction of the light guide element 50 is perpendicular to the light sensor 40. That is, in some embodiments, the light incident direction of the light guide element 50 is perpendicular to the opening 22. Alternatively, in some embodiments, the light-emitting direction of the light guide element 50 is perpendicular to the light sensor 40. Alternatively, in some embodiments, the light incident direction of the light guide element 50 is perpendicular to the opening 22, and the light emergent direction of the light guide element 50 is perpendicular to the light sensor 40. Thus, most of the visible light transmitted through the opening 22 reaches the light sensor 40 after passing through the light guide element 50, so that the light sensor 40 has a high accuracy in detecting the ambient light.

In some embodiments, opening 22 includes a device portion 222 and a light-transmitting portion 224, device portion 222 is disposed corresponding to the functional device, and light guide element 50 is used for guiding light transmitted through light-transmitting portion 224 to light sensor 40. In this way, while light transmitted through the light-transmitting portion 224 is transmitted to the optical sensor 40, the mutual influence between the functional device and the optical sensor 40 can be reduced or avoided.

Referring to fig. 14, in some embodiments, there are two light guide elements 50, two light sensors 40, and each light sensor 40 is disposed corresponding to one light guide element 50. Thus, the angles of the light received by the two light sensors 40 can be mutually compensated, and the accuracy of dimming can be ensured. Specifically, when the top portion 24 and the bottom portion 26 of the housing 20 are respectively opened with the top opening 22d and the bottom opening 22c, two light guide elements 50, i.e., a top light guide element 50a corresponding to the top photosensor 40a and a light guide element 50b corresponding to the bottom photosensor 40b, may be respectively disposed at the top portion 24 and the bottom portion 26. It can be understood that when a user uses the electronic device 100 in the same environment, the angle at which the light sensor 40 receives visible light may change when the user tilts the electronic device, which may cause the brightness of the display screen to change significantly, thereby affecting the user experience. And two light sensors 40 are arranged, so that the brightness of the display screen 13 can be accurately adjusted, and better user experience is guaranteed.

In some embodiments, the outer perimeter of light directing element 50 is coated with a black coating. This prevents loss of visible light emitted from the outer peripheral surface of the light guide element 50, and reduces the accuracy of the optical sensor 40 in detecting ambient light.

In some embodiments, light sensor 40 comprises an ambient light sensor for sensing ambient light, and a processor for adjusting the brightness of the display screen based on the intensity of light sensed by the ambient light sensor.

Specifically, when the user is under the sun, the ambient light is strong, the ambient light receiver feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to enhance the brightness of the display screen to adapt to the light intensity of the current environment, so that the content of the screen viewed by the user is clearer. When the user is in a dark environment, the ambient light is weak, the ambient light receiver feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to reduce the brightness of the display screen to adapt to the light intensity of the current environment, so that the user does not feel dazzling when watching the screen content, and the optimal visual effect is provided for the user. Therefore, the method is not only beneficial to protecting the eyesight of the user, but also saves the electric quantity of the mobile phone and can further achieve the effect of prolonging the service life of the battery.

Referring to fig. 3 and fig. 15, a method for manufacturing an electronic device 100 according to an embodiment of the present invention includes the following steps:

s301, providing a display screen 13, wherein the display screen 13 comprises a display area 1311 and a non-display area 1312;

s302, providing an infrared sensor 16, wherein the infrared sensor 16 includes a transmitter 161 for transmitting infrared light and a receiver 162 for receiving infrared light;

s303, disposing the infrared sensor 16 below the display 13 so that the emitter 161 is located in the non-display area 1312; and

s304, providing a light blocking member 30, disposing the light blocking member 30 between the emitter 161 and the display region 1311, wherein the light blocking member 30 is used to block infrared light emitted by the emitter 161 from entering the display region 1311.

Specifically, the electronic device 100 employs the display 13, the infrared sensor 16 may be disposed below the display 13 in the case of a full screen, and the emitter 161 of the red sensor 16 may be disposed in the non-display area 1312, so as to prevent infrared light emitted by the emitter 161 from affecting the operating stability of the TFT of the display area 1311, so that the display 13 and the infrared sensor 16 may implement their respective functions without interfering with each other. The display 13 may be an Organic Light-Emitting Diode (OLED) display, and the OLED display has good Light transmittance and can pass visible Light and infrared Light. Therefore, the OLED display screen does not influence the infrared sensor to emit and receive infrared light under the condition of showing the content effect. The display screen 13 may also be a Micro LED display screen, which also has good transmittance for visible light and infrared light. Of course, these display screens are merely exemplary and embodiments of the present invention are not limited in this respect. In addition, the upper surface 131 of the display 13 is used for displaying the content effect through visible light on the one hand, and for transmitting infrared light on the other hand, so that the infrared sensor 16 normally emits and receives infrared light.

In some embodiments, the method of manufacturing the electronic device 100 further comprises the steps of:

a touch layer 12 is provided on the display 13. And

a cover plate 11 is disposed on the touch layer 12.

Specifically, the touch layer 12 is mainly used for receiving an input signal generated when a user touches the touch layer 12 and transmitting the input signal to the circuit board for data processing, so as to obtain a specific position where the user touches the touch layer 12. The touch layer 12 and the display screen 13 can be attached by adopting an In-Cell or On-Cell attaching technology, so that the weight of the display screen can be effectively reduced, and the overall thickness of the display screen can be reduced. In addition, the cover plate 11 is disposed on the touch layer 12, so that the touch layer 12 and the internal structure thereof can be protected, and direct damage of the touch layer 12 caused by external force is avoided.

In some embodiments, the method for manufacturing the electronic device 100 further includes, before the step S303, the steps of:

applying a first coating layer 14 to the lower surface 132;

step S303 specifically includes:

an infrared sensor 16 is disposed below the display screen 13 and covers the first coating layer 14 over an emitter 161, the emitter 161 for emitting infrared light through the first coating layer 14.

Specifically, the first coating layer 14 may employ an IR ink, and since the IR ink has a characteristic of low transmittance to visible light, the emitter 161 disposed under the first coating layer 14 may not be perceived based on human eye's vision when the electronic device 100 is viewed from the outside. Meanwhile, the IR printing ink has the characteristic of high light transmittance to infrared light, so that the emitter 161 can stably emit the infrared light, and the normal work of the emitter 161 is ensured.
