Description

Technical Field

[0001] This invention relates to the field of liquid crystal displays, and more particularly to a display module, assembly method, control method, device, and medium. Background Technology

[0002] Among related technologies, borderless full-screen displays, as a brand-new display technology, bring people a brand-new visual experience and sensory impact, and have become the goal pursued by display manufacturers. In order to achieve an extremely high screen ratio, the current method is to place the camera below the display.

[0003] While placing the camera under the display screen allows it to occupy the display space, the existing camera installation method results in low transmittance due to the screen obstruction, leading to lower image quality. Based on this, related under-display camera technologies propose to improve transmittance by reducing the pixel size or density of the display screen. However, reducing the pixel size or density will reduce the display quality and seriously affect the viewing experience. Summary of the Invention

[0004] The main objective of this invention is to provide a display module, assembly method, control method, device, and medium, aiming to solve the technical problem that existing under-display camera display module technologies cannot simultaneously achieve high image quality and high display quality.

[0005] To achieve the above objectives, the present invention provides a display module, the display module comprising:

[0006] Display screen;

[0007] A light guide plate, wherein a groove is provided inside the light guide plate;

[0008] A camera assembly, comprising a camera, a first conductive film with light guiding function, and a second conductive film with light enhancement function, wherein the camera is disposed in the groove, and the first conductive film and the second conductive film are arranged alternately along the shooting direction of the camera;

[0009] The control component includes a conduction control module and a drive control module. The conduction control module is used to control the conduction state of the first conductive film and the second conductive film, and the conduction state includes a transparent state and a fogged state.

[0011] Optionally, the inner wall of the groove is provided with a plurality of reflective particles, wherein the plurality of reflective particles are arranged unevenly on the inner wall of the groove.

[0012] Optionally, the display module further includes:

[0013] Glass front cover;

[0014] A frame is provided, in which the light guide plate is placed. The display screen and the glass front cover are arranged sequentially on one side of the frame along the shooting direction of the camera.

[0015] A glass back cover, wherein the glass back cover is disposed on the opposite side of the plastic frame from the camera assembly;

[0016] Optical adhesive is applied to the inner upper wall of the recess in the glass front cover for attaching the display screen. The optical adhesive is also applied to the top side of the light guide plate not covered by the adhesive frame and the top side of the glass front cover for attaching the glass front cover.

[0017] The present invention also provides a method for assembling a display module, the display module comprising a glass front cover, a display screen, a frame, a light guide plate, and a glass back cover, the light guide plate having a light guide plate body, a first conductive film and a second conductive film attached to the light guide plate body, and a camera placed in a groove in the light guide plate body, the method for assembling the display module comprising the following steps:

[0018] A pressing fixture is provided, the glass front cover is placed in the pressing fixture, optical adhesive is applied to the upper wall of the recess of the glass front cover and the optical adhesive is exposed to light to obtain cured optical adhesive;

[0019] Align the display screen with the cured optical adhesive;

[0020] After attaching the top surface of the frame to the other side of the display screen, the light guide plate is placed into the frame through the opening of the frame. The optical adhesive is applied to the top side of the light guide plate not covered by the frame and the top side of the glass front cover, and the optical adhesive is then exposed to light to obtain the cured optical adhesive.

[0021] After aligning the glass back cover with the cured optical adhesive, the glass front cover, the light guide plate, and the glass back cover are pressed together with a preset pressure using the pressing fixture to obtain the display module.

[0022] The present invention also provides a control method for a display module, the control method for the display module comprising the following steps:

[0023] In response to the camera activation signal, the first switching timing of the working state of the first conductive film and the second switching timing of the working state of the second conductive film are adapted to each other, and by applying a drive to the display area corresponding to the projection of the first conductive film and the second conductive film on the display screen, the liquid crystal molecules located inside the display area are controlled to be vertically aligned with the display area, so that the display area enters the display off state;

[0024] In response to the camera shutdown signal, the first conductive film and the second conductive film are de-energized, and the display area is put into the display on state.

[0025] Optionally, the step of matching the first switching timing of the operating state of the first conductive diaphragm with the second switching timing of the operating state of the second conductive diaphragm includes:

[0026] The first switching timing for controlling the working state of the first conductive film to be in a transparent state and the second switching timing for controlling the working state of the second conductive film to be in a transparent state are adapted to each other.

[0027] Optionally, the step of controlling the display area to enter the display-on state includes:

[0028] The liquid crystal molecules located inside the display area and the liquid crystal molecules located inside other display areas are controlled to tilt along the axial direction so that the display area enters the display on state.

[0029] In addition, to achieve the above objectives, the present invention also provides a display device, including a memory, a processor, and a computer processing program stored in the memory and executable on the processor, wherein the processor executes the computer processing program to implement the steps of the control method for the display module described above.

[0030] In addition, to achieve the above objectives, the present invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the control method for the display module described above.

[0031] This invention, in response to a camera activation signal, adapts a first switching timing of the operating state of the first conductive film and a second switching timing of the operating state of the second conductive film to the same condition. By applying a drive to the display area corresponding to the projections of the first and second conductive films onto the display screen, it controls the liquid crystal molecules within the display area to align perpendicularly to the display area, thereby putting the display area into a display-off state. Based on the high light-guiding effect of the first conductive film and the high light-enhancing efficiency of the second conductive film, the camera in the activated state can transmit light through the transparent first and second conductive films and the display area. The system captures high-quality images of the target user and / or target scene without reducing the pixel size or density of the display screen. In response to a camera off signal, it de-energizes the first and second conductive films and controls the display area to enter the display on state. By de-energizing the first and second conductive films and putting them into a fogging state without capturing images of the target user and / or target scene through the camera, the system avoids the situation where the brightness of the display area is higher than other display areas due to the transparent state of the first and second conductive films, thus improving the display quality.

[0044] The realization of the objective of this invention, its functional features and advantages will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0046] like Figure 1 As shown, Figure 1 This is a schematic diagram of the terminal structure of the hardware operating environment involved in the embodiments of the present invention.

[0047] The control method for the display module in this embodiment of the invention is applied to a display device, such as... Figure 1 As shown, the display device may include: a processor 1001, such as a CPU; a network interface 1004; a user interface 1003; a memory 1005; and a communication bus 1002. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display area and an input unit such as a keyboard. Optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0048] Optionally, the display device may also include a camera, RF (Radio Frequency) circuitry, sensors, audio circuitry, a WiFi module, and so on. Sensors may include light sensors, motion sensors, and other sensors. Specifically, light sensors may include ambient light sensors and proximity sensors. The ambient light sensor can adjust the brightness of the display screen according to the ambient light level, while the proximity sensor can turn off the display screen and / or backlight when the mobile terminal is moved to the ear. As a type of motion sensor, a gravity accelerometer can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity, and can be used for applications that identify the mobile terminal's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition functions (such as pedometers, taps), etc. Of course, the mobile terminal may also be equipped with other sensors such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, which will not be elaborated here.

[0049] Those skilled in the art will understand that Figure 1 The display device structure shown does not constitute a limitation on the display device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0050] like Figure 1 As shown, the memory 1005, which serves as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a computer processing program.

[0051] exist Figure 1 In the terminal shown, network interface 1004 is mainly used to connect to the backend server and communicate data with it; user interface 1003 is mainly used to connect to the client (user terminal) and communicate data with it; while processor 1001 can be used to call the computer processing program stored in memory 1005 and perform the following operations:

[0052] In response to the camera activation signal, the first switching timing of the working state of the first conductive film and the second switching timing of the working state of the second conductive film are adapted to each other, and by applying a drive to the display area corresponding to the projection of the first conductive film and the second conductive film on the display screen, the liquid crystal molecules located inside the display area are controlled to be vertically aligned with the display area, so that the display area enters the display off state;

[0053] In response to the camera shutdown signal, the first conductive film and the second conductive film are de-energized, and the display area is put into the display on state.

[0054] Furthermore, the processor 1001 can call a computer program stored in the memory 1005 and also perform the following operations:

[0055] The step of matching the first switching timing of the working state of the first conductive film with the second switching timing of the working state of the second conductive film includes: matching the first switching timing of the first conductive film to be in a transparent state with the second switching timing of the second conductive film to be in a transparent state.

[0056] Furthermore, the processor 1001 can call a computer program stored in the memory 1005 and also perform the following operations:

[0057] The step of controlling the display area to enter the display on state includes: controlling the liquid crystal molecules located inside the display area and the liquid crystal molecules located inside other display areas to tilt along the axial direction, so that the display area enters the display on state.

[0058] Reference Figure 2 , Figure 2 This is a schematic diagram of the structure of the display module of the present invention, as shown below. Figure 2 It can be seen that the display module includes:

[0059] Display screen 70;

[0060] Light guide plate 20, wherein a groove 50 is provided inside the light guide plate 20;

[0061] The camera assembly includes a camera 10, a first conductive film 30 with light guiding function, and a second conductive film 40 with light enhancement function. The camera 10 is disposed in the groove 50, and the first conductive film 30 and the second conductive film 40 are arranged at intervals along the shooting direction of the camera 10.

[0062] The control component includes a conduction control module and a drive control module. The conduction control module is used to control the conduction state of the first conductive film 30 and the second conductive film 40, and the conduction state includes a transparent state and a fogged state. The drive control module is used to control the display state of the display area corresponding to the projection of the first conductive film 30 and the second conductive film 40 on the display screen 70.

[0063] Specifically, based on the technical content of under-display cameras and the existing problem of the inability to simultaneously achieve high-quality video and high-quality display content, the reason why existing under-display cameras produce low-quality video content is that the current installation method results in insufficient light intake, leading to severe loss of detail and blurry video content. Therefore, this application proposes, without reducing the pixel size or pixel density of the display screen 70, to add a first conductive film 30 with a light-guiding function and a second conductive film 40 with a light-enhancing function to the lens side of the camera 10. When the camera 10 is in the activated state and captures images of the target user and / or target scene, the liquid crystal molecules inside the first conductive film 30, which is in a conductive state, are neatly arranged and transparent. Based on the first conductive film 30 in its transparent state, the liquid crystal molecules inside are transparent. The light passing through the first conductive film 30 to the lens side of the camera 10 is enhanced, thereby improving the light guiding effect and improving the image clarity of the camera 10. At the same time, combined with the second conductive film 40 in a conductive state, the liquid crystal molecules inside the second conductive film 40 are neatly arranged and transparent. Based on the transparent state of the second conductive film 40, the intensity of the light passing through the second conductive film 40 to the lens side of the camera is enhanced, improving the light enhancement efficiency and reducing stray light, further improving the image clarity of the camera 10. This allows the image quality of the camera 10 to be almost as close as the image quality without the screen obstruction. The combination of the first conductive film 30 and the second conductive film 40 can improve the light transmittance of the display screen 70, thereby achieving high-quality image content without reducing the pixel size or pixel density of the display screen 70.

[0064] It should be noted that the system also includes control components for controlling the states of the first conductive film 30, the second conductive film 40, and the display area. Specifically, it includes a conduction control module and a drive control module. The conduction control module controls the conduction state of the first conductive film 30 and the second conductive film 40 according to the state of the responding camera signal. Similarly, the drive control module controls the display state of the display area according to the state of the responding camera signal. If the responding camera signal is a camera-on signal, the conduction control module controls the first conductive film 30 and the second conductive film 40 to conduct and enter a transparent state, while the drive control module controls the display area to enter a closed state. If the responding camera signal is a camera-off signal, the conduction control module controls the first conductive film 30 and the second conductive film 40 to de-energize and enter a fogging state, while the drive control module controls the display area to enter an open state.

[0065] Furthermore, the first conductive film 30 is disposed between the lens side of the camera 1 and the inner upper wall of the groove 50, and the second conductive film 40 is disposed at intervals on the side of the light guide plate 20 away from the camera 10.

[0066] Reference Figure 2 It can be seen that the camera 10 is disposed within the groove 50 of the light guide plate 20, and the first conductive film 30 is disposed between the lens side of the camera 10 and the inner upper wall of the groove 50, wherein the inner upper wall refers to... Figure 2 At the end of the groove 50 furthest from the glass back cover 90, the second conductive film 40 is spaced apart on the side of the light guide plate 20 furthest from the camera 10. The spacing is set according to the actual application scenario, ensuring that the distance between the first conductive film 30 and the lens side of the camera 10 is less than the distance between the second conductive film 40 and the lens side of the camera 10. Specifically, according to Figure 2 As can be seen, in this embodiment, the frame 60 is provided with two light guide plates 20, wherein the first conductive film 30 is disposed in the first light guide plate 20, and the second conductive film 40 is disposed between the bonding area of ​​the first light guide plate 20 and the second light guide plate 20. However, since the distance between the first conductive film 30 and the second conductive film 40 does not affect the image quality, the second conductive film 40 can also be disposed in the first light guide plate 20 at a distance from the first conductive film 30, so that the first conductive film 40 and the second conductive film 30 can work together to improve the image quality of the camera 10.

[0067] It should be noted that a light guide plate 20 is also provided between the display screen 70 and the frame 60.

[0068] Furthermore, the display module also includes:

[0069] Glass front cover 80;

[0070] A frame 60 is provided, in which the light guide plate 20 is placed. The display screen 70 and the glass front cover 80 are arranged sequentially on one side of the frame 60 along the shooting direction of the camera 10.

[0071] A glass back cover 90 is disposed on the side of the frame 60 opposite to the camera assembly.

[0072] Optical adhesive 100 is applied to the inner upper wall of the recess of the glass front cover 80 for attaching the display screen 70. The optical adhesive 100 is also applied to the top side of the light guide plate 20 not covered by the adhesive frame 60 and the top side of the glass front cover 80 for attaching the glass front cover 80.

[0073] The light guide plate 20 is encased in a protective frame 60 and positioned beneath the display screen 70, allowing the camera 10 to be completely hidden beneath the display screen 70. This avoids the pitfalls of under-display camera installation techniques, such as mounting the camera on a bezel around the display screen or using a flip-up device to mount the camera on the back of the LCD device, thus maximizing the screen-to-body ratio. A glass front cover 80 is placed on the display screen 70 to reduce light reflection, ensuring users can clearly see the content displayed on the screen. A glass back cover 90 is located on the other side of the light guide plate 20, and a backlight is installed on the glass back cover 90 to enable the display screen 70 to produce an illuminated image effect.

[0074] It should be noted that the display screen and the front glass cover 80, the light guide plate 20 and the back glass cover 90, and the front glass cover 80 and the back glass cover 90 are bonded together with optical adhesive 100, so as to attach the display screen and the front glass cover 80, as well as the light guide plate 20 and the back glass cover 90 together without affecting the light transmittance, to form a display module.

[0075] Furthermore, referring to Figure 3 The inner wall of the groove 50 is provided with a plurality of reflective particles 110, wherein the arrangement of the plurality of reflective particles 110 on the inner wall of the groove 50 is non-uniform.

[0076] Because the display screen has a backlight, and the diffraction of light from the backlight can cause light spots on the captured content, thus affecting the image quality, based on this situation, refer to Figure 3 This application arranges a number of reflective particles 110 around the inner frame of the groove 50 of the light guide plate 20 where the camera 10 is located, i.e., on the inner sidewall. The arrangement density of the reflective particles 110 is different, making them non-uniform. When the backlight shines on each reflective particle 110, the reflected light will diffuse in all directions and then break the emission conditions and be emitted from the front of the light guide plate 20. By arranging reflective particles 110 with different densities, the light guide plate 20 can convert the line light source into a surface light source for planar output. This achieves the effect of reducing the light spots in the image content caused by light diffraction, while also improving the light guide uniformity of the camera 10 by using the converted surface light source, thereby further improving the image quality.

[0077] Reference Figure 4 , Figure 4 This is a flowchart illustrating the assembly method of the display module of the present invention. In this embodiment, the assembly method of the display module includes the following steps:

[0078] A10 provides a pressing fixture, in which the glass front cover 80 is placed, and optical adhesive 100 is applied to the upper wall of the recess of the glass front cover 80 and the optical adhesive 100 is irradiated to obtain cured optical adhesive 100.

[0079] A20, Align the display-functional side of the display screen 70 with the cured optical adhesive 100.

[0080] After the glass front cover 80 is placed face down into the pressing fixture, a recess is formed in the glass front cover 80 inside the pressing fixture. Optical adhesive 100 is applied to the inner upper wall of the recess (i.e., the side of the recess with the inner frame facing up), and the optical adhesive 100 is cured by light. This allows the flow of the optical adhesive 100 to be controlled, preventing the optical adhesive from overflowing during assembly. Then, the display screen 70 with the display function is pressed onto the cured optical adhesive 100, so that the cured optical adhesive 100 bonds the display screen 70 and the glass front cover 80 together, preventing the glass front cover 80 and the display screen 70 from moving relative to each other and causing wear.

[0081] A30, after attaching the top surface of the frame 60 to the other side of the display screen 70, insert the light guide plate 20 into the frame 60 through the opening of the frame 60, apply the optical adhesive 100 to the top side of the light guide plate 20 not covered by the frame 60 and the top side of the glass front cover 80, and irradiate the optical adhesive 100 to obtain the cured optical adhesive 100.

[0082] A40, after aligning the glass back cover 90 with the cured optical adhesive 100, the glass front cover 80, the light guide plate 20 and the glass back cover 90 are pressed together with a preset pressure using the pressing fixture to obtain the display module.

[0083] After attaching the top surface of the frame 60 to the other side of the display screen 70, the light guide plate 20 is inserted into the frame 60 through the opening, so that the frame 60 can wrap around the light guide plate 20, thus protecting the light guide plate 20. At this time, part of the light guide plate 20 is exposed at the opening of the frame 60. Optical adhesive 100 is applied to the exposed part of the light guide plate 20, and optical adhesive 100 is also applied to the side of the front glass cover 80 (i.e., the side with the inner frame of the recess facing upwards). After curing the optical adhesive 100 by light exposure, the back glass cover 90 is bonded to the light guide plate 20 and the front glass cover 80. Then, the front glass cover 80, the light guide plate 20 and the back glass cover 90 are pressed together by a pressing fixture with a preset pressure to reinforce the display module and improve the production qualification rate of the display module.

[0084] The preset pressure of the pressing fixture is based on the actual pressure parameters of each pressing fixture.

[0085] Reference Figure 5 , Figure 5 This is a flowchart illustrating the control method for the display module of the present invention. In this embodiment, the control method for the display module includes the following steps:

[0086] Step S10: In response to the camera activation signal, the first switching timing of the working state of the first conductive film and the second switching timing of the working state of the second conductive film are matched. By applying a drive to the display area corresponding to the projection of the first conductive film and the second conductive film on the display screen, the liquid crystal molecules located inside the display area are controlled to be vertically aligned with the display area, so that the display area enters the display off state.

[0087] In response to the camera activation signal, indicating that the camera needs to be activated for recording, the display screen needs to display images while the camera located below the screen also needs to record. Therefore, in order for the camera to capture high-quality video content, the first and second conductive films are switched on, matching the first switching timing of the first conductive film's working state with the second switching timing of the second conductive film's working state. The interaction between the first and second conductive films improves the light transmittance of the display screen. At the same time, the display area corresponding to the positions of the first and second conductive films is controlled to enter the display off state, preventing the display image on the display area from obstructing the camera. This achieves high-quality video content without reducing the pixel size or pixel density of the display screen.

[0088] according to Figure 6 It can be seen that when the camera is turned on, in order to prevent the displayed image from obstructing the camera, a drive is applied to the display area, causing the liquid crystal molecules inside the display area (i.e., Figure 6 In the configuration 140), the backlight light is perpendicular to the upper and lower polarizers. When the light from the backlight passes through the liquid crystal layer of the liquid crystal molecules inside the display area via the lower polarizer, because the liquid crystal molecules are vertically aligned, the light passes straight through the upper polarizer. At this point, the display area becomes transparent, preventing the displayed image from obstructing the camera. Simultaneously, no force is applied to the liquid crystal molecules inside other display areas to ensure normal display of images in those areas. Figure 6 The white rectangle in the image represents the second conductive film, and the black rectangle represents the first conductive film.

[0089] Specific references Figure 7 It can be seen that, Figure 7 In response to the camera activation signal, the display module is in a display state in which the display area and other display areas are not a single display unit. The first conductive film and the second conductive film are turned on and the display area enters a transparent state, so that the first conductive film and the second conductive film can work together to improve the camera's image quality and prevent the display image on the display area from obstructing the camera.

[0090] It should be noted that, Figure 7 The diamond pattern in the image represents the scene.

[0091] Existing methods use algorithms to compensate for camera content, thereby improving video quality. However, this method only works for shooting static content. When shooting moving content, the algorithm cannot be used, failing to meet the requirements for capturing high-definition moving video. In contrast, this application directly applies the functions of the first and second conductive films to the camera, thus avoiding the limitations of existing methods. Compared to algorithmic compensation, its application scenarios are much broader.

[0092] Optionally, the step of matching the first switching timing of the working state of the first conductive diaphragm and the second switching timing of the working state of the second conductive diaphragm in step S10 includes:

[0093] Step S101, the first switching timing for controlling the working state of the first conductive film to be in a transparent state is matched with the second switching timing for controlling the working state of the second conductive film to be in a transparent state.

[0094] Specifically, when the camera is turned on to capture images of the target user and / or target scene, the first conductive film, which is in a conductive state, becomes transparent. The transparent state of the first conductive film enhances the light-guiding effect, thereby improving the camera's image clarity. Simultaneously, the second conductive film, which is in a conductive state, becomes transparent, enhancing the light-enhancing efficiency and reducing stray light, further improving the camera's image clarity. This allows the camera's image quality to approach that of an image without a display screen obstruction. The combination of the first and second conductive films also increases the light transmittance of the display screen, achieving high-quality video content without reducing the pixel size or pixel density of the display screen.

[0095] Step S20: In response to the camera shutdown signal, the first conductive film and the second conductive film are de-energized, and the display area is put into the display on state.

[0096] In response to the camera off signal, it indicates that the camera does not need to be turned on for recording. The display screen only needs to display the image. Therefore, to avoid abnormal display caused by the first and second conductive films when the display screen only needs to display the image, the first and second conductive films need to be de-energized. In the de-energized state, the liquid crystal molecules inside the first and second conductive films are irregularly dispersed and appear to be in a fogged state. At the same time, the display area corresponding to the first and second conductive films is controlled to perform normal display operation.

[0097] Specific references Figure 8 As shown, according to Figure 8 It can be seen that, Figure 8 In response to the camera off signal, the display module enters a display state where the display area and other display areas are displayed as a single unit. The first and second conductive films are de-energized and enter a fogging state, and the camera (i.e.,...) Figure 8 The dotted circle in the image enters the off state to prevent the brightness of the display area from being higher than other display areas due to the first and second conductive films in the transparent state, thus avoiding the situation where the display brightness is different.

[0098] It should be noted that, Figure 8 The diamond pattern in the image represents the scene.

[0099] Optionally, the step of controlling the display area to enter the display-on state in step S20 includes:

[0100] Step S201: Control the liquid crystal molecules located inside the display area and the liquid crystal molecules located inside other display areas to tilt along the axial direction so that the display area enters the display on state.

[0101] It should be noted that the display screen consists of an upper polarizing plate, a liquid crystal layer, and a lower polarizing plate, according to... Figure 9 It can be seen that when the display area and other display areas are a single display unit, the liquid crystal molecules inside the display area (i.e., the dashed line positions corresponding to the first and second conductive films) (i.e., Figure 9 In the 140 area and other display areas, the liquid crystal molecules are tilted along the same axis according to the direction of the electric field. Therefore, when the backlight light passes through the lower polarizer and this liquid crystal layer in which the liquid crystal molecules are tilted along the axis, most of the light will deviate from the original propagation direction, which reduces the amount of light passing through the upper polarizer and makes the display screen able to display the image normally.

[0102] in, Figure 9 The white rectangle in the image represents the second conductive film, and the black rectangle represents the second conductive film.

[0103] In this embodiment, by matching the first switching timing of the working state of the first conductive film and the second switching timing of the working state of the second conductive film in response to the camera-on signal, and by applying a drive to the display area corresponding to the projection of the first and second conductive films on the display screen, the liquid crystal molecules located inside the display area are controlled to align perpendicularly with the display area, so that the display area enters the display-off state. Based on the high light guiding effect of the first conductive film and the high light enhancement efficiency of the second conductive film, the camera in the on state can transmit light through the transparent first conductive film, the second conductive film, and the display screen. The display area captures high-quality images of the target user and / or target scene without reducing the pixel size or density of the display screen. In response to a camera off signal, it controls the first and second conductive films to de-energize and controls the display area to enter the display on state. By controlling the first and second conductive films to de-energize and enter a fogging state when not capturing images of the target user and / or target scene through the camera, it avoids the situation where the brightness of the display area is higher than other display areas due to the first and second conductive films in a transparent state, thus improving the display quality.
