For example, in the existing display panels and devices, a light sensor is usually set in the display module, such as components such as the camera in the mobile phone screen. The camera function is realized by the light sensor. The front cameras in the display modules on the market are mostly punched, and the physical device is set to avoid the backlight source from affecting the light leakage of the camera. However, the aperture corresponding to the camera is usually large, which will visually affect the display imaging of the display panel and is not conducive to the pictures taken during the shooting process. Especially for display panels with high refresh rates, when shooting, due to the influence of the aperture and external environmental factors, such as when the external ambient light is weak, the picture formed by the picture will be underexposed and the display picture will be dark, which is not conducive to further improving the comprehensive performance of the display module and display panel.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0045] With the continuous development of display equipment and device manufacturing technology, people have put forward higher requirements on the performance and display effect of display panels.

[0046] For display modules with camera imaging functions, their camera performance and imaging effects will directly affect people's user experience. When taking photos and imaging, the modules in the prior art usually have problems such as underexposure, dark images, and unsatisfactory imaging effects.

[0047] The embodiments of the present application provide a display module and a camera driving method for the display module, so as to effectively improve the display effect and camera effect of the display panel and improve the comprehensive performance of the display panel and the device.

[0048] like Figure 1 As shown, Figure 1 Schematic diagram of the film structure of a display module provided in an embodiment of the present application. Specifically, the display module includes a first film layer 100, a second film layer 101, a light guide plate 102, a first backlight module 103, a display panel 104, a light emitting component 105, a second backlight module 106 and a camera assembly 107.

[0049] Specifically, when preparing the above display module, the second film layer 101 is disposed on the first film layer 100 , the light guide plate 102 is disposed on the second film layer 101 , and at the same time, the first backlight module 103 is disposed on the light guide plate 102 .

[0050] In the embodiment of the present application, the first film layer 100 and the second film layer 101 can be set as functional film layers, such as the first film layer 100 is set as a protective layer, and the second film layer 101 can be set as an enhancement layer, through which the film layers in the display module are protected, and at the same time, the light propagating in the display module is enhanced by the enhancement layer, thereby improving the propagation effect and performance of the light in the module. Alternatively, according to the actual product, the first film layer 100 and the second film layer 101 can be set as other functional film layers, which will not be described in detail here.

[0051] Further, in the embodiment of the present application, when the light propagates in the display module, the light is emitted by the light emitting component 105, passes through different film layers in sequence, enters the light guide plate 102, and propagates in the light guide plate 102. In the embodiment of the present application, the light emitting component 105 can be set as a component with a light emitting function, such as in the embodiment of the present application, the light emitting component 105 is set as a light emitting diode. And the light emitting diode is set on one side of the second backlight module 106, so that part of the light emitted by the light emitting diode will enter the second backlight module 106, and part of the light will enter the first backlight module 103 through other film layers, thereby ensuring the normal light emitting display of the display panel.

[0052] In the embodiment of the present application, the first backlight module 103 is disposed on the light guide plate 102, and the display panel 104 is disposed on the first backlight module 103. Specifically, the first backlight module 103 is disposed on a side away from the light emitting side of the display panel.

[0053] Further, in the embodiment of the present application, the display module further includes a display area 21 and a camera area 22. Specifically, the display area 21 is arranged on at least one side of the camera area 22. In the embodiment of the present application, the display area 21 can be arranged around the camera area 22.

[0054] Specifically, the display module further includes a through hole 23. The through hole 23 is correspondingly arranged in the camera area 22, and the through hole 23 penetrates the multi-layer film layer. Wherein, when the above-mentioned through hole 23 and each film layer structure are arranged, the first backlight module 103 is correspondingly arranged in the display area 21, and the second backlight module 106 is correspondingly arranged in the camera area 22. And because the aperture of the through hole 23 in the camera area 22 is generally small, the area of ​​the second backlight module 106 is smaller than the area of ​​the first backlight module 103.

[0055] In the embodiment of the present application, the first backlight module 103 is arranged around the through hole 23, and the first backlight module 103 is arranged on a side close to the display panel 104, and the second backlight module 106 is arranged on a side away from the display panel, such as the second backlight module 106 is arranged at a corresponding position of the bottom of the through hole 23. Thus, different backlight modules provide backlight to different film layers.

[0056] In the embodiment of the present application, the display module and the display panel have a first working state and a second working state when they are working normally. In the following embodiments, the first working state is described as a screen display state corresponding to the normal display mode, and the second working state is described as a camera state corresponding to the camera mode.

[0057] Specifically, in the first working state, the first backlight module 103 and the second backlight module 106 are both in an on state, and at this time, the display panel can display different pictures normally.

[0058] like Figure 2 As shown, Figure 2 The timing diagram corresponding to the display module provided in the embodiment of the present application during normal display. In the timing diagram, from top to bottom, the control timing diagrams of the display panel 104, the second backlight module 106 and the first backlight module 103 are respectively corresponded. It can be seen that when the display panel 104 is working normally, under multi-frame display, a driving signal is periodically provided to the display panel 104. At the same time, in each frame, the first backlight module 103 and the second backlight module 106 are both in the on state, and the camera component 107 is turned off, so that the display picture is displayed normally.

[0059] Meanwhile, in the first working state, the display panel corresponding to the second backlight module 106 can display normally, thereby ensuring the display effect of the display panel.

[0060] In the second working state, if the user needs to use the display panel to take a picture, the backlight of the second backlight module 106 is turned off, and the camera assembly 107 is turned on to make the camera assembly 107 work.

[0061] See Figure 3 As shown, Figure 3 A schematic diagram of the timing sequence corresponding to the display module in the camera mode provided in the embodiment of the present application. Figure 2In the embodiment of the present application, in the second working state, in order to improve the performance of the camera assembly 107 and avoid affecting the shooting effect. Specifically, at this time, the control timing of the first backlight module 103 and the second backlight module 106 is changed. For example, the backlight of the second backlight module 106 in the camera area is turned off, and at the same time, the camera assembly 107 is turned on. At this time, the display panel 104 in the corresponding area above the camera assembly 107 is in a high-transmittance state, thereby ensuring that as much light as possible enters the camera assembly, thereby improving its imaging effect.

[0062] At the same time, in the second working state, by controlling the on / off state of the first backlight module 103 in different control time segments, the performance of the camera assembly 107 is effectively improved, and the imaging and display effects of the panel are improved.

[0063] Specifically, when shooting, the display panel may further include a plurality of different control timing segments. In different control timing segments, the first backlight module is in different on or off states. For example, the control timing segment may include a first control timing segment t1 and a second control timing segment t2 adjacent to the first control timing segment t1.

[0064] The first control timing segment t1 and the second control timing segment t2 both correspond to one frame of image. At the same time, in the first control timing segment t1 and the second control timing segment t2, the second backlight module 106 is turned off, and in the first control timing segment t1, the first backlight module 103 is turned off, and the camera assembly 107 is turned on. At this time, the camera assembly 107 can receive external light signals, thereby scanning the picture to be shot, and further convert the light signal into an electrical signal, and the electrical signal is converted into a digital signal through the corresponding digital-to-analog conversion module. In the second control timing segment t2, the camera assembly 107 is turned off, and the first backlight module 103 is turned on. At this time, the display panel displays the preview picture according to the above digital signal. In the embodiment of the present application, the required shooting picture is imaged and displayed through a single adjustment control.

[0065] In the embodiment of the present application, in each control timing segment, taking 1s as an example, 120 frames can be displayed in 1s, and each frame is about 8.3ms. Therefore, when the camera component 107 is scanning, it only takes 8.3ms to expose a frame, and the time for turning on and off the backlight is 8.3ms. Therefore, during the switching of the first backlight, the human eye will not feel the flicker and distinguish that the first backlight is turned off at this display refresh frequency, thereby ensuring the normal operation of the display panel and ensuring the visual effect and experience of the human.

[0066] Furthermore, the display module may also include a control chip. When controlling the first backlight module 103, the control chip is used to control the scanning signal to the first backlight module and ensure the normal operation of the module.

[0067] like Figure 4 As shown, Figure 4 The schematic diagram of the effect of taking a picture provided in the embodiment of the present application is shown in FIG. By controlling the opening and closing of the first backlight module in different control time sequences, a normal display picture is ensured during shooting.

[0068] Furthermore, in order to improve the camera performance of the display module, the embodiment of the present application also provides another camera driving method of the display module. Specifically, the method comprises the following steps:

[0069] S100: providing a display module in an embodiment of the present application;

[0070] S101: when the display module is in the first working state, turning on the first backlight module and the second backlight module of the display module, turning off the camera assembly of the display module, and making the display module emit light and display normally;

[0071] S102: Switching the first working state to a second working state, and turning off the second backlight module;

[0072] S103: Turn on the camera assembly, receive external light signals, and scan the image to be shot multiple times, wherein when scanning is performed in different control time sequences, different areas of the image to be shot are scanned respectively;

[0073] S104: After each scan is completed, the scanned data is stored until the entire area of ​​the image to be captured is scanned;

[0074] S105: Processing the stored scan data and displaying it.

[0075] Specific, combined Figure 3 In order to further improve the camera effect of the display module, in the embodiment of the present application, when the display module is performing normal display, its driving mode is the same as Figure 2 When the display mode is switched to the second working state, the first backlight module in the second working state is adjusted and controlled multiple times, and the shooting and display are performed.

[0076] like Figure 5 As shown, Figure 5 The second display module provided in the embodiment of the present application is in the timing diagram of the camera mode. Figure 3 In the timing diagram, in the embodiment of the present application, in the second working state, it includes multiple different control timing segments, and in the scanning period corresponding to each control timing segment, different areas of the picture to be captured are scanned respectively, and the corresponding pictures in different areas are obtained, and the scanned data are stored.

[0077] Specifically, in the first control timing section t1, due to switching from the display state to the camera state, the first backlight module is turned off and the camera assembly is turned on to receive external light signals and scan the image to be captured.

[0078] Specifically, Figure 6 As shown, Figure 6 Schematic diagram of the imaging effect provided in the embodiment of the present application. Figure 5 In the timing diagram, two scans are used as an example to illustrate the process of multiple scanning and imaging. In the first scan, assuming the scanning time is t1, at this time, half of the picture A to be shot can be scanned, that is, corresponding to the first area S1, and in the second scan, the other half of the unscanned picture to be shot is scanned, that is, corresponding to the second area S2. In this way, it is equivalent to scanning in batches, and each scan obtains pictures in different areas. Specifically, more scans can be performed. At this time, in each scan, the camera component scans 1 / n areas of the picture to be shot each time, n is the number of scans, and multiple areas eventually form the entire picture A.

[0079] In the first control time segment t1, the first area S1 of the scanning image is scanned.

[0080] After the first area S1 is scanned, the first backlight module is turned on and the camera assembly is turned off within the second control timing section t2. At the same time, the data corresponding to the scanned first area S1 is previewed and displayed, and the obtained data is stored.

[0081] After the first preview display is completed, what is obtained is the picture in the first area S1 corresponding to the entire picture.

[0082] After the picture corresponding to the first area S1 is shot, the picture A is shot for the second time. At this time, during the second shooting process, the picture corresponding to the second area S2 of the picture A is scanned and shot, and then the above steps are repeated, and the picture in the second area S2 is previewed, displayed, and stored. Among them, the first area S1 obtained in the first scan and the second area S2 obtained in the second scan are different areas, and the first area S1 and the second area S2 may not overlap, or there may be partial overlap. When there is an overlapping area, the area of ​​the overlapping area is less than one tenth of the area of ​​each shot. In this way, it can effectively prevent the problem of incoordination when multiple shots are taken in the same area and the final superposition is performed, and the camera effect of the display panel is effectively guaranteed.

[0083] After the second area S2 of the screen A is photographed, it is previewed. During the preview, since the data corresponding to the first area S1 is stored in the storage module, it is retrieved from the storage module and previewed together with the data corresponding to the second area S2, thereby obtaining a picture of the entire screen A.

[0084] In an embodiment of the present application, during the shooting and imaging process, multiple scans are performed, and a different area is scanned each time. In this way, the entire image can be regarded as being divided into multiple units, and each small unit is photographed, exposed and imaged separately. In this way, the exposure time of the picture can be effectively increased, thereby improving the shooting effect of the picture.

[0085] In the embodiment of the present application, when scanning the image to be photographed multiple times, such as the first scan, the camera assembly starts from the first line of the image to be photographed, and scans downward line by line until it scans half of the entire image, and then stops scanning. Therefore, in each scanning process, a part of the camera assembly can be scanned, such as the upper half of the camera assembly works normally, and scans the image.

[0086] Furthermore, in the embodiment of the present application, the image to be captured can be directly divided, such as dividing the image to be captured into multiple different areas, and scanning a specific area each time until all the divided areas are scanned. The method is the same as the above-mentioned multiple scanning method, which will not be repeated here.

[0087] In the embodiment of the present application, the first control time segment t1 and the second control time segment t2 have the same time length, which can be set to 8.3 ms. Figure 3 In the timing diagram, in the embodiment of the present application, since the picture is exposed twice, when the whole picture is shot, the total exposure time is Figure 3 This effectively improves the camera effect of the display module.

[0088] Further, such as Figure 7 As shown, Figure 7 A schematic diagram of the flow chart corresponding to the camera driving method of the display module provided in an embodiment of the present application.

[0089] Combination Figure 3-Figure 6 As shown in the figure, in the embodiment of the present application, when the picture is photographed, by controlling the opening and closing of the first backlight module and the second backlight module, when shooting, the backlights corresponding to the first backlight module and the second backlight module are first turned off, and then the external light signal is obtained through the camera component, and the collected light signal is converted into an electrical signal, and the electrical signal is processed by the digital-to-analog converter to form a digital signal. The digital signal passes through the digital signal processor again, and the processed data is transmitted to the control chip of the display module or the corresponding processor to form the required picture.

[0090] In the embodiment of the present application, when shooting a picture, the picture is scanned and exposed multiple times, and the data obtained by exposure is stored, and the area exposed each time is a different area. After the final exposure is completed, the data obtained by multiple exposures are displayed, and finally the picture shot in the embodiment of the present application is formed. Therefore, in the embodiment of the present application, the camera driving method can effectively increase the exposure processing time of the picture, thereby effectively improving the shooting effect of the picture and improving the comprehensive performance of the display module.

[0091] In summary, a display module and a camera driving method for a display module provided in an embodiment of the present invention are introduced in detail above.
