Description

Technical Field

[0001] The present application belongs to the field of display technology, and in particular relates to a display panel, an anti-peeping display method, equipment, a storage medium, and a display device. Background Art

[0002] Currently, a display panel is typically composed of a plurality of pixels arranged in an array, each pixel including a pixel circuit and a light-emitting element. When the display panel is displaying an image normally, the image may be secretly photographed by others through illegal photography, resulting in the leakage of the image content.

[0003] The existing anti-secret-photography technology mainly reduces the angle of light emitted from the display panel, thereby reducing the display viewing angle so that the displayed image can only be viewed from the normal viewing angle of the display panel.

[0004] However, when the display viewing angle is limited, since the displayed image can be viewed at the normal viewing angle of the display panel, others can also secretly photograph the image content displayed on the display panel by shooting from the front, thereby causing the image content to be leaked. Summary of the Invention

[0005] The embodiments of the present application provide a display panel, an anti-peeping display method, an apparatus, a storage medium, and a display device, which can solve the technical problem in the prior art that it is impossible to prevent the displayed content from being secretly photographed.

[0006] In a first aspect, an embodiment of the present application provides a display panel, the display panel comprising:

[0007] Multiple pixels, multiple pixels are arranged in an array;

[0008] A scanning signal control module includes a plurality of shift register units, wherein the scanning signal terminals of pixels in the same row are electrically connected to corresponding shift register units;

[0009] A driving chip, the driving chip includes a plurality of data signal output terminals, and the data signal terminals of pixels in the same column are respectively connected to corresponding data signal output terminals;

[0010] a driver chip, configured to, in a second mode, determine, in each image frame, a plurality of first pixels displaying a normal image and a plurality of second pixels displaying an interference image, and provide a first data signal to the plurality of first pixels and a second data signal to the plurality of second pixels; the first data signal being a data signal corresponding to the normal image, and the second data signal being a data signal corresponding to the interference image;

[0011] In a unit time, a ratio of the number of image frames displayed by a single pixel as a second pixel to the total number of image frames displayed by the single pixel in the unit time is less than or equal to a preset interference image frame ratio.

[0012] In a second aspect, an embodiment of the present application provides an anti-peeping display method, which is applied to the above-mentioned display panel, and the method includes:

[0013] In the second mode, a preset interference pixel ratio is obtained;

[0014] Determining, based on the interference pixel ratio, a plurality of first pixels displaying a normal image and a plurality of second pixels displaying an interference image in each image frame; wherein, within a unit time, a ratio of the number of image frames displayed by a single pixel as a second pixel to the total number of image frames displayed within the unit time is less than or equal to a preset interference image frame ratio;

[0015] According to the corresponding plurality of first pixels and the plurality of second pixels in each image frame, first data signals are provided to the plurality of first pixels and second data signals are provided to the plurality of second pixels.

[0016] In a third aspect, an embodiment of the present application provides an anti-peeping display device, the anti-peeping display device comprising: a processor and a memory storing computer program instructions;

[0017] The processor implements the above-mentioned anti-peeping display method when executing computer program instructions.

[0018] In a fourth aspect, an embodiment of the present application provides a computer storage medium having computer program instructions stored thereon, which implement the above-mentioned anti-peeping display method when the computer program instructions are executed by a processor.

[0019] In a fifth aspect, an embodiment of the present application provides a display device, which includes the above-mentioned display panel.

[0020] Compared with the prior art, the display panel, anti-peeping display method, device, storage medium and display device provided in the embodiments of the present application can, in the second mode, determine multiple first pixels and multiple second pixels in each image frame, and provide a corresponding first data signal to the first pixel and a corresponding second data signal to the second pixel. The first pixel can display a normal image under the first data signal, and the second pixel can display an interference image under the second data signal. In a unit time, the ratio of the number of image frames in which a single pixel in the display panel serves as a second pixel to the total number of image frames displayed by it in the unit time can be set to be less than or equal to a preset interference image frame ratio. When someone takes a secret photo, the captured image is a mixture of a normal image and an interference image, thereby hiding part of the content of the normal image and preventing the leakage of the image content. By setting a suitable interference pixel ratio, the ratio of image frames in which a single pixel displays an interference image in a unit time to the total image frames displayed by it in the unit time can be lower than the level that can be recognized by the human eye. Due to the influence of the persistence of vision effect of the human eye, the pixels displaying the interference image are difficult to be recognized by the human eye and will not affect the user's normal viewing. When others take secret photos, the image they capture is a mixed image formed by the normal image displayed by the first pixel and the interference image displayed by the second pixel. The interference image can effectively block or neutralize the image content of the normal image, thereby avoiding the leakage of image content when others take secret photos.

[0021] Optionally, the interference image is not related to the content of the normal image. For example, when the interference image is a fixed image, the multiple second pixels of the display panel in the second mode display the interference image under the second data signal. Compared with the normal image displayed in the first mode, the pixel positions corresponding to the multiple second pixels in the second mode no longer display the image content of the normal image, but display the image content of the interference image, thereby achieving masking and covering of the normal image.

[0022] Optionally, when the interference image is generated by adjusting parameters of the normal image, there is a correlation between the interference image and the normal image. For example, the interference image can be generated by adjusting parameters such as the RGB color values, brightness values, or color coordinate values ​​of the normal image. In the second mode, when the normal image and the interference image are superimposed at the same position in two image frames, even if the voyeur uses the voyeur camera for a long exposure time, the color or brightness of the pixels in the two frames will be neutralized, making it impossible to identify the image content displayed in the normal image in the mixed image captured by the voyeur.

[0038] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0039] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The embodiments will be described in detail below with reference to the accompanying drawings.

[0041] Existing display panel products are generally composed of a plurality of pixels arranged in an array. A pixel may include a pixel circuit and a light-emitting element. The pixel circuit may provide a driving current to the light-emitting element so that the light-emitting element emits light.

[0042] When a display panel displays image content normally, the image content may be secretly photographed by others in front of the display panel, resulting in image leakage. Existing anti-secret photography technologies mainly limit the emission angle of light emitted by the display panel, thereby restricting the display viewing angle. The image content displayed on the display panel can only be viewed from the front of the display panel.

[0043] However, even if the display viewing angle is limited, when others are at a full viewing angle, they can secretly photograph the image content displayed on the display panel by shooting from the front, thereby causing leakage of the image content.

[0044] In order to solve the above technical problems, the embodiments of the present application provide a display panel, an anti-peeping display method, an apparatus, a storage medium, and a display device. The display panel provided by the embodiments of the present application is first introduced below.

[0045] Figure 1 FIG2 is a schematic diagram showing the structure of a display panel provided by an embodiment of the present application. The display panel includes a scanning signal control module 30 , a driving chip 20 and a plurality of pixels 10 .

[0046] The plurality of pixels 10 in the display panel may be arranged in an array.

[0047] The scanning signal control module 30 may include a plurality of shift register units. Among the plurality of pixels 10, the scanning signal terminals of the pixels 10 in the same row may be electrically connected to the corresponding shift register units. That is, each shift register unit may be electrically connected to a corresponding row of pixels 10.

[0048] The driving chip 20 may include multiple data signal output terminals, and the data signal terminals of the pixels 10 in the same column among the multiple pixels 10 may be connected to corresponding data signal output terminals. That is, the data signal terminals of the pixels 10 in the same column are connected to the same data signal output terminal.

[0049] It can be understood that in order to reduce the number of ports of the data signal output end of the driver chip 20 or the number of signal lines in the data fan-out area of ​​the display panel, multiple multiplexers MUX can also be set in the display panel. The multiplexer MUX can respectively connect a data signal output end of the driver chip 20 with multiple pixel columns to provide data signals to multiple pixel columns through one data signal output end.

[0050] The display panel can display image content in a first mode and a second mode. In the first mode, the display panel can display image content normally. In the second mode, the display panel can control some pixels 10 to display normal images and some pixels 10 to display interference images, so that the actual image displayed is a mixture of normal images and interference images. In the second mode, even if others use a camera to shoot the image content displayed on the display panel, the image obtained is also formed by a mixture of normal images and interference images. The interference image part in the actual image can cover or neutralize the specific image content, so that the voyeur cannot shoot the complete normal image content, effectively preventing others from taking secret photos and avoiding the leakage of image content.

[0051] It is understandable that the interference image may be an image with content irrelevant to the normal image, or may be generated by adjusting parameters of the normal image.

[0052] Optionally, the interference image is not related to the content of the normal image. When the interference image is a fixed image, the multiple second pixels of the display panel in the second mode display the interference image under the second data signal. Compared with the normal image displayed in the first mode, the pixel positions corresponding to the multiple second pixels in the second mode no longer display the image content of the normal image, but display the image content of the interference image, thereby achieving masking and covering of the normal image.

[0053] Optionally, when the interference image is generated by adjusting parameters of the normal image, there is a correlation between the interference image and the normal image. For example, the interference image can be generated by adjusting parameters such as the RGB color values, brightness values, or color coordinate values ​​of the normal image. In the second mode, when the normal image and the interference image are superimposed at the same position in two image frames, even if the voyeur uses the voyeur camera for a long exposure time, the color or brightness of the two frames will be neutralized, making it impossible to identify the image content displayed by the normal image in the mixed image captured by the voyeur.

[0054] In each image frame in the second mode, the driver chip 20 can determine multiple first pixels and multiple second pixels in the image frame. The first pixels and the second pixels are both part of the multiple pixels 10 in the display panel. There is no overlap between the first pixels and the second pixels. That is, in a single image frame, if a pixel 10 emits light, it is either a first pixel or a second pixel. The total number of pixels 10 emitting light in the image frame is the sum of the number of first pixels and the number of second pixels.

[0055] In each image frame, the first pixel may display a normal image, and the second pixel may display an interference image. After determining the corresponding plurality of first pixels and second pixels in the image frame, the driver chip 20 may provide a corresponding first data signal to each first pixel and a corresponding second data signal to each second pixel.

[0056] It is understood that the drive signal can determine the normal image and interference image corresponding to each image frame. When a pixel 10 in the image frame is determined to be a first pixel, the corresponding data signal is determined based on the target display parameters corresponding to the pixel 10 in the normal image. This data signal is the first data signal corresponding to the first pixel. Correspondingly, when a pixel 10 in the image frame is determined to be a second pixel, the corresponding data signal is determined based on the target display parameters corresponding to the pixel 10 in the interference image. This data signal is the second data signal corresponding to the second pixel.

[0057] Since each row of pixels 10 is driven row by row in each image frame using a row scanning drive method, taking one row of pixels 10 as an example, the driver chip 20 can determine the first pixel and the second pixel in the row of pixels 10, and when the shift register unit corresponding to the row of pixels 10 outputs a scan signal, the driver chip 20 can output the corresponding first data signal through the data signal output end corresponding to each first pixel, and output the corresponding second data signal through the data signal output end corresponding to each second pixel. Then, multiple first pixels in the row of pixels 10 display a normal image, and multiple second pixels display an interference image. For each row of pixels 10, the driver chip 20 can provide the first data signal to the first pixel in the row of pixels 10 and the second data signal to the second pixel in the row of pixels 10 when the shift register unit corresponding to each row of pixels 10 outputs a scan signal. Then, in the image frame, each first pixel displays a normal image through the corresponding first data signal, and each second pixel displays an interference image through the corresponding second data signal.

[0058] It is understood that in each image frame in the second mode, multiple second pixels are present. These multiple second pixels receive corresponding second data signals, thereby displaying interference images at the pixel positions corresponding to the multiple second pixels. If someone else photographs the display area of ​​the display panel, the image content displayed at the pixel positions corresponding to the second pixels in the resulting image frame is not a normal image, but rather an interference image. Therefore, even if someone else photographs the display panel, they will not be able to capture a complete, normal image, thereby preventing image content leakage.

[0059] Please refer to Figure 2 and Figure 3 In one example, Figure 2 It shows a portion of pixels 10 of the display panel in the first mode, and the portion of pixels 10 all receive corresponding first data signals. Figure 3 It shows the normal image displayed by the part of pixels 10 under the first data signal.

[0060] Please refer to Figure 4 and Figure 5 , in another example, Figure 4 A portion of pixels 10 of the display panel in the second mode is shown, and the portion of pixels 10 includes a plurality of first pixels and a plurality of second pixels, wherein the first pixels receive corresponding first data signals, and the second pixels receive corresponding second data signals. Figure 5 The mixed image of the normal image and the interference image displayed by the part of pixels 10 under the first data signal and the second data signal is shown.

[0061] By comparing Figure 3 and Figure 5From the image content shown, it can be determined that, in the second mode, the display panel can display the corresponding interference image through multiple second pixels, so that there is a large difference between the mixed image formed by the normal image and the interference image and the original normal image. Even if others take a picture of the display panel, they cannot capture a complete normal image.

[0062] For a single pixel in a display panel, the ratio of the number of image frames displayed as a second pixel per unit time to the total number of image frames displayed per unit time should be set to be less than or equal to a preset interference image frame ratio. The interference image frame ratio refers to the ratio of the number of image frames displaying an interference image as a second pixel to the total number of image frames, under the premise that the human eye cannot perceive the interference image. When the ratio of the image frames displayed as a second pixel per unit time to the total number of image frames is less than or equal to the interference image frame ratio, the human eye can never perceive that the single pixel displays an interference image.

[0063] For example, when the preset interference image frame ratio is 1:11, in order to prevent the human eye from perceiving that a single pixel displays an interference image, the ratio of the number of image frames displayed by a single pixel as a second pixel per unit time to the total number of image frames displayed per unit time should be set to be less than or equal to 1:11. Calculations show that, when the unit time is 1 second, the refresh rate of the display panel is 60 Hz, and the number of image frames displayed by a single pixel as a second pixel per unit time is 5, the ratio of the image frames displayed as the second pixel to the total number of image frames is 1:12. This ratio is less than 1:11, satisfying the requirement that the ratio be less than or equal to the interference image frame ratio. On the other hand, when the number of image frames displayed by a single pixel as a second pixel per second is 6, the ratio of the image frames displayed as the second pixel to the total number of image frames is 1:10. This ratio is greater than 1:11, failing to satisfy the requirement that the ratio be less than or equal to the interference image frame ratio. Therefore, when the preset interference image frame ratio is 1:11, if the refresh frequency of the display panel is 60 Hz, the number of image frames displayed by a single pixel as the second pixel in a unit time of one second should be less than or equal to 5.

[0064] It is understood that, when the preset interference image frame ratio is 1:11, if the refresh rate of the display panel is 120 Hz, then the number of image frames displayed by a single pixel as the second pixel per second should be set to be less than or equal to 10. Similarly, when the preset interference image frame ratio remains unchanged, if the refresh rate of the display panel is 144 Hz, then the number of image frames displayed by a single pixel as the second pixel per second should be set to be less than or equal to 12.

[0065] It should be noted that the human eye experiences persistence of vision. This phenomenon refers to the phenomenon whereby when observing a scene, light signals are transmitted to the brain for a brief period of time. After the light ceases to act, the visual image does not immediately disappear. This residual visual impression is called an "afterimage," and this visual phenomenon is known as "persistence of vision." Typically, the duration of human visual persistence is approximately 0.1s-0.4s. That is, the content of a normal image will remain in the human eye for approximately 0.1s-0.4s. If the display duration of an interfering image is shorter than this duration, the interfering image will not be perceived by the human eye, thereby preventing it from affecting normal viewing of the normal image. For example, when the refresh rate of a display panel exceeds 11Hz, the display duration of each image frame is approximately 0.09s. For example, if 11 image frames are arranged to consist of 10 normal images and one interfering image, the human eye will not perceive the interfering image as being displayed on that single pixel because the interfering image's display duration is shorter than this duration. Accordingly, when the refresh rate is 48 Hz, the number of interfering image frames is within 4 frames, and the display duration does not exceed 0.1 seconds, thus not affecting the normal viewing experience. When the refresh rate is 60 Hz, the number of interfering image frames is within 5 frames, and the display duration does not exceed 0.1 seconds, thus not affecting the normal viewing experience. Based on the actual refresh rate of the display panel, a corresponding interfering image frame ratio can be set so that the display duration of an interfering image frame displayed by a single pixel in the display panel per unit time is less than the persistence of vision of the human eye, thereby preventing the human eye from perceiving the interfering image.

[0066] It is understandable that the number of image frames displayed by a single pixel as the second pixel per unit time can also be 0. That is, in the second mode, some pixels 10 can continue to display normal images as first pixels, and will not display interference images as second pixels.

[0067] In this embodiment, the display panel can determine the multiple first pixels and multiple second pixels in each image frame when displaying the image frame in the second mode. The display panel driver chip 20 can provide a corresponding first data signal or second data signal based on whether the pixel 10 is a first pixel or a second pixel, so that the first pixel displays a normal image in the image frame and the second pixel displays an interference image in the image frame. Furthermore, the ratio of the number of image frames displayed as the second image by a single pixel in the display panel per unit time to the total number of image frames is no greater than a preset interference image frame ratio, thereby preventing the human eye from perceiving the interference image when the single pixel displays the interference image and thus preventing the human eye from viewing the displayed content normally. Regarding the camera device, the image captured is a mixed image formed by a mixture of the normal image displayed by the first pixel and the interference image displayed by the second pixel. The interference image can effectively obscure or neutralize the image content of the normal image, thereby preventing the leakage of image content when someone secretly photographs it.

[0068] In some embodiments, in each image frame in the second mode, the number of first pixels and the number of second pixels may be set to satisfy the following first formula:

[0069] 1 / 3>n / m>1 / 10;

[0070] Wherein, m is the number of the first pixels, and n is the number of the second pixels. That is, in each image frame, the ratio of the number of second pixels displaying interference images to the number of first pixels displaying normal images can be set to a range of one tenth to one third.

[0071] When the ratio of the number of second pixels to the number of first pixels is one-third, the number of second pixels accounts for one-quarter of all illuminated pixels in the image frame. When the ratio of the number of second pixels to the number of first pixels is one-tenth, the number of second pixels accounts for one-eleventh of all illuminated pixels in the image frame. When the ratio of the number of first pixels to the number of second pixels is within the above range, the interference image displayed by the second pixels in the image frame can effectively mask and neutralize the content displayed by the normal image, preventing the leakage of the normal image content during candid photography.

[0072] It can be understood that in a single image frame, if the number of second pixels displaying the interference image is greater, the image content captured by the shooting device will contain less normal image content, and the anti-secret photography effect will be better.

[0073] In a single image frame, the ratio of the number of second pixels to the number of first pixels should be at least greater than 1:10 and less than 1:3. When the ratio of the number of second pixels to the number of first pixels reaches 1:10, the image area of ​​the interference image in a single image frame is sufficient to achieve the effect of preventing sneak shots. When the ratio of the number of second pixels to the number of first pixels is greater than or equal to 1:3, the interference image in the image frame corresponding to this ratio accounts for a large proportion of the total display area. At this time, in order to avoid a single pixel being displayed as a second pixel for too long and being perceived by the human eye as displaying an interference image, it is necessary to reduce the number of second pixels in other image frames. When the number of second pixels in other image frames is small, the interference image formed cannot effectively mask or neutralize the normal image, which will result in a reduction in the anti-sneak shooting effect in other image frames.

[0074] In some embodiments, in at least two image frames in the second mode, at least one first pixel in the previous image frame becomes a second pixel in the next image frame. That is, at least one pixel displays a normal image in the previous image frame and displays an interference image in the next image frame.

[0075] Accordingly, in at least two image frames in the second mode, at least one second pixel in the previous image frame becomes a first pixel in the next image frame, that is, at least one pixel displays an interference image in the previous image frame and displays a normal image in the next image frame.

[0076] It is understandable that, in the above two transformation methods of the preceding and following image frames, when at least one of the conditions is satisfied, there is a difference between the display area of ​​the interference image of the preceding image frame and the display area of ​​the interference image of the following image frame.

[0077] To prevent voyeurs from capturing the image content while also preventing the normal viewing of the image content displayed by the display panel from being affected, the duration for which a single pixel within the display panel displays an interfering image as a second pixel should be shorter than the duration of the human eye's persistence of vision. If the duration for which a single pixel displays an interfering image as a second pixel falls within the duration of the human eye's persistence of vision, the interfering image content will be visible to the human eye, thereby affecting the normal viewing of the image.

[0078] It is understood that in order to ensure that the time a single pixel is displayed as a second pixel is shorter than the duration of the human eye's persistence of vision, the single pixel needs to switch between the first pixel and the second pixel in different image frames. This ensures that each pixel does not display an interfering image as the second pixel for too long, causing the interfering image to be perceived by the human eye. Therefore, there are at least two image frames in the second mode, resulting in a difference in the number of second pixels or the pixel position of each second pixel between the two image frames.

[0079] When at least one first pixel in a previous image frame becomes a second pixel in a subsequent image frame, it indicates that the pixel position displayed a normal image and an interference image in the two preceding and succeeding image frames, respectively, and the image displayed at least at that pixel position has changed between the two image frames. Similarly, when at least one second pixel in a previous image frame becomes a first pixel in a subsequent image frame, it indicates that the pixel position displayed an interference image and a normal image in the two preceding and succeeding image frames, respectively, and the image displayed at least at that pixel position has also changed between the two image frames.

[0080] It should be noted that the at least two image frames in the second mode can be two adjacent image frames or two non-adjacent image frames. For example, when the refresh rate of the display panel is 120Hz, even if the number and position of the first pixels in two consecutive image frames do not change, and the number and position of the second pixels do not change, since the display duration of the two image frames is less than 0.02s, even if the position and number of the second pixels do not change, the human eye cannot perceive the existence of the interfering pixel. That is, in a plurality of consecutive image frames, when the position and number of each second pixel do not change, if the display duration of each second pixel in the plurality of image frames is less than the persistence of vision of the human eye, it will not be perceived by the human eye.

[0081] It is understandable that, based on the refresh frequency of the display panel, the number of image frames displayed when the number and position of the second pixels are changed can also be adjusted. For example, when the refresh frequency of the display panel is low, the number and position of the second pixels can be changed in every two adjacent image frames, so that the number and position of the second pixels in any two adjacent image frames are not completely consistent. When the refresh frequency of the display panel is high, the number and position of the second pixels can be changed every few image frames, and the number and position of the second pixels within these few image frames do not change. The driver chip can provide the second data signal to the same multiple second pixels within these few image frames, thereby saving power consumption of the display panel.

[0082] In some embodiments, in at least two image frames in the second mode, all second pixels in the previous image frame become first pixels in the next image frame. That is, all pixels that displayed an interference image as second pixels in the previous image frame display a normal image in the next image frame.

[0083] It is understood that the two preceding and following image frames can be adjacent or non-adjacent. Multiple pixel locations that displayed an interfering image in the preceding image frame all display a normal image in the following image frame. Accordingly, among the multiple first pixels that displayed a normal image in the preceding image frame, some of the first pixels become second pixels in the following image frame, displaying the interfering image.

[0084] In some embodiments, the interference image may be an inverted image obtained by inverting the normal image.

[0085] When a voyeur uses a camera to capture a scene, the captured image is a mixture of the normal image and its inverse image. For each local area of ​​the display panel, the light output colors of the pixels displaying the normal image and the surrounding pixels displaying the inverse image are neutralized. This makes the image content displayed in each local area of ​​the captured image unrecognizable due to the inverse neutralization, making it impossible to extract the image content from the captured image.

[0086] It is understood that the above-mentioned color inversion processing can be performed by inverting the RGB color values ​​displayed by the pixel in the normal image. For example, if the RGB color value displayed by a pixel in the normal image is (R, G, B), the color value displayed by the pixel in the inverted image is (255-R, 255-G, 255-B).

[0087] Please refer to Figures 6 to 8 , Figure 6 is the normal image corresponding to the display panel when displaying a certain image frame. The RGB color value of each pixel in the normal image is inverted to obtain Figure 7 After determining the first pixel and the second pixel among the plurality of pixels, the display panel can provide a first data signal corresponding to the normal image according to the pixel position of each first pixel and provide a second data signal corresponding to the inverted image according to the pixel position of each second pixel. Then the image displayed by the display panel is Figure 8 The mixed image of the normal image and the inverted image is shown. It can be understood that Figure 8 In the mixed image shown, due to the neutralization of the normal image and its inverted image, the image content in the normal image can be effectively masked, thereby preventing leakage of the image content.

[0088] In some embodiments, the interference image may include identification information, which may include at least one of characters, images, and patterns. This identification information can be used to indicate that the image was captured in an illegal manner. For example, the identification information may include the producer of the displayed normal image to indicate the owner of the image. The identification information may also include text or watermark content indicating that the image was captured illegally, so that others who view the image formed by the mixture of the normal image and the interference image can understand from the display area of ​​the interference image that the image was captured illegally.

[0089] like Figure 9As shown, after forming the watermark content by at least one of text, numbers or patterns, the watermark content can be used as identification information, and multiple identification information can be evenly arranged in the interference image. In the second mode, the display panel can provide the second data signal corresponding to the interference image according to the pixel positions corresponding to the multiple second pixels in each pixel frame, so that each second pixel displays part of the identification information at the corresponding pixel position. The image content displayed by the display panel in the image frame is as shown in FIG. Figure 10 As shown, the identification information displayed by each second pixel can enable others to read the content expressed by the identification information when viewing the secretly photographed image.

[0090] In the above embodiment, the interference image may include a plurality of identification information arranged evenly or a plurality of identification information arranged irregularly.

[0091] Since the interference image is displayed only through a portion of the second pixels in the display panel, and the distribution positions of the individual second pixels may be uniform, concentrated, or randomly distributed, if the identification information in the interference image is only set at a fixed position, and there are no second pixels or a small number of second pixels in the area where the fixed position is located, the content expressed by the identification information cannot be accurately identified from the captured image. By configuring the interference image to be composed of multiple pieces of identification information arranged evenly or irregularly, the identification information can be displayed in the image captured by the voyeur even when the number and position of the second pixels are constantly changing.

[0092] It is understandable that if the number of second pixels in a single image frame is small, and the second pixels are not concentrated in a certain area but are dispersed, the human eye may not be able to recognize the identification information from the interference image displayed by the dispersed second pixels in the captured image. Therefore, in order to enable the human eye to recognize the identification information from the interference image portion in the captured image, it is necessary to set a lower limit for the ratio of second pixels to total pixels or the ratio of second pixels to first pixels in a single image frame. For example, the lower limit of the ratio of the number of second pixels to first pixels can be set to one-tenth, that is, the number of second pixels should be at least one-eleventh of the pixels that emit light in the display panel, thereby avoiding the situation where the identification information cannot be recognized from the interference image displayed by the second pixels due to the small number of second pixels.

[0093] An embodiment of the present application further provides an anti-peeping display method, which is applied to the display panel in the above embodiment. Figure 11 A flowchart of an anti-peeping display method provided by an embodiment of the present application is shown. The method includes the following steps:

[0094] S1110, in the second mode, obtaining a preset interference pixel ratio;

[0095] S1120, determining, based on the interference pixel ratio, a plurality of first pixels displaying a normal image and a plurality of second pixels displaying an interference image in each image frame; wherein, within a unit time, a ratio of the number of image frames displayed by a single pixel as a second pixel to the total number of image frames displayed within the unit time is less than or equal to a preset interference image frame ratio;

[0096] S1130 , providing a first data signal to the plurality of first pixels and a second data signal to the plurality of second pixels according to the plurality of first pixels and the plurality of second pixels corresponding to each image frame.

[0097] In this embodiment, in the second mode, the display panel can determine the first pixel and the second pixel in each image frame based on a preset interference pixel ratio, and provide a corresponding first data signal to the first pixel and a corresponding second data signal to the second pixel within the image frame, so that the first pixel in the image frame displays a normal image and the second pixel displays an interference image. Furthermore, the ratio of the number of image frames displayed as the second image by a single pixel in the display panel per unit time to the total number of image frames is no greater than the preset interference image frame ratio. This ensures that when a single pixel displays an interference image, it is not perceived by the human eye and does not affect the normal viewing of the displayed content. Regarding the camera device, the image captured is a mixed image formed by the normal image displayed by the first pixel and the interference image displayed by the second pixel. In this mixed image, the interference image can effectively obscure or neutralize the image content of the normal image, thereby preventing the leakage of image content when others secretly photograph it.

[0098] In S1110, the display panel can display image content normally in the first mode, and in the second mode, the display panel can obtain a preset interference pixel ratio and control some pixels to display normal images and some pixels to display interference images according to the interference pixel ratio.

[0099] It is understandable that the interference pixel ratio may be preset when the display panel leaves the factory, or may be adjusted when the user triggers a corresponding adjustment instruction.

[0100] In S1120, after obtaining the preset interference pixel ratio, the driver chip of the display panel can determine the number and positions of multiple first pixels and the number and positions of multiple second pixels in each image frame based on the interference pixel ratio. The multiple first pixels can display a normal image, and the multiple second pixels can display an interference image.

[0101] It should be noted that the display panel displays a mixed image formed by a normal image and an interference image in the second mode to prevent surreptitious photography. The interference image obscures or neutralizes the normal image in the image captured by the surreptitious photographer, preventing image content from being leaked. While preventing image content from being leaked due to surreptitious photography, it is also necessary to avoid affecting normal viewing of the image content displayed on the display panel. Due to the persistence of vision phenomenon, if a single pixel displays a low number of image frames per unit time as a second pixel, the human eye will not perceive the interference image. However, if a single pixel displays a high number of image frames per unit time as a second pixel, the human eye will perceive the interference image, thereby affecting normal viewing. Therefore, the ratio of the number of image frames displayed by a single pixel in the display panel as a second pixel per unit time to the total number of image frames displayed per unit time should be less than or equal to a preset interference image frame ratio. This interference image frame ratio can be adjusted based on the time range of human persistence of vision and the current refresh rate of the display panel, so that when a single pixel displays an interference image per unit time as a second pixel, the human eye will not perceive it.

[0102] As an alternative embodiment, please refer to Figure 12 The above S1120 may include:

[0103] S1210, dividing a plurality of pixels of the display panel into a plurality of pixel groups according to a preset pixel combination method;

[0104] S1220 , determining the number of first pixels and the number of second pixels in each pixel group according to the interference pixel ratio.

[0105] In this embodiment, the display panel may divide a plurality of pixels into a plurality of pixel groups according to a preset pixel combination method, and determine the number of first pixels and the number of second pixels in each pixel group according to the interference pixel ratio.

[0106] In S1210, the display panel determines the first pixel and the second pixel in a single image frame by dividing multiple pixels of the display panel into multiple pixel groups according to a preset pixel combination method, and dividing multiple pixels in each pixel group into first pixels and second pixels respectively.

[0107] As an optional embodiment, the above S1210 may include:

[0108] Divide i pixels in the same row into a pixel group; i is a positive integer greater than or equal to 4;

[0109] Alternatively, j pixels in the same column are divided into a pixel group; j is a positive integer greater than or equal to 4;

[0110] Alternatively, k*p pixels in k rows and p columns are divided into a pixel group; k and p are positive integers greater than or equal to 2.

[0111] In this embodiment, the preset pixel combination method may be at least one of the following three division methods:

[0112] i) dividing i pixels in the same row into a pixel group; i is a positive integer greater than or equal to 4;

[0113] In this division method, the display panel can divide multiple pixels in the same row into a pixel group. One or more pixels in this pixel group can be used as second pixels, while the other pixels are used as first pixels. In addition, the position and number of second pixels in this pixel group can be changed in different image frames, thereby preventing a single pixel in the pixel group from displaying an interfering image for too long as the second pixel displays an interfering image, which could cause the human eye to perceive the interfering image.

[0114] It is understood that when a single pixel group includes a second pixel, the number of pixels in the pixel group can be set to be greater than or equal to 4, that is, i ≥ 4. In this case, the proportion of the second pixel in the total pixels in the pixel group is less than or equal to one-quarter. In this case, for the mixed image displayed by the display panel, the proportion of the interference image displayed by the second pixel is less than or equal to one-quarter. This can avoid the situation where the proportion of the second pixel in some image frames is too large, resulting in a smaller number of second pixels in other image frames. The interference image displayed by the second pixel in each image frame can achieve the effect of masking or neutralizing the normal image.

[0115] ii) dividing j pixels in the same column into a pixel group; j is a positive integer greater than or equal to 4;

[0116] Similar to the above division method, the display panel can divide multiple pixels in the same column into a pixel group, in which one or more pixels in the pixel group can serve as second pixels, while the other pixels serve as first pixels. Similarly, when a single pixel group includes a second pixel, the number of pixels in the pixel group can be set to be greater than or equal to 4, that is, j ≥ 4. In this case, for the mixed image displayed by the display panel, the display area of ​​the interference image displayed by the second pixel is less than or equal to one-quarter of the overall display area, which does not result in the proportion of the second pixel in certain image frames being too small. Therefore, the interference image displayed by the second pixel in each image frame can achieve the effect of masking or neutralizing the normal image.

[0117] iii) k*p pixels in k rows and p columns are divided into a pixel group; k and p are positive integers greater than or equal to 2.

[0118] In this division method, the display panel can divide a pixel matrix formed by k*p pixels with k rows and p columns into a pixel group. One or more pixels in the pixel group can serve as second pixels, and the other pixels serve as first pixels. Similar to the reason for setting the number of pixel groups mentioned above, when a single pixel group includes a second pixel, the number of pixels in the pixel group can be set to be greater than or equal to 4. Due to the use of a matrix division method with k rows and p columns, when k and p are both positive integers greater than or equal to 2, that is, k≥2 and p≥2, the number of pixels in the formed pixel matrix is ​​greater than or equal to 4. At this time, for the mixed image displayed by the display panel, the display area of ​​the interference image displayed by the second pixel is less than or equal to one-quarter of the overall display area, which does not cause the proportion of the second pixel in some image frames to be too small, so that the interference image displayed by the second pixel in each image frame can achieve the effect of masking or neutralizing the normal image.

[0119] It should be noted that the above-mentioned pixel combination methods can be applied individually or in combination. That is, each pixel in the display panel can be divided into pixel groups using one of the above-mentioned pixel combination methods, or two or three combinations can be used to divide the pixel groups.

[0120] In S1220 , after dividing the plurality of pixels in the display panel into pixel groups according to the preset pixel combination method, the number of first pixels and the number of second pixels in each pixel group may be determined according to the preset interference pixel ratio.

[0121] It is understandable that after determining the number of first pixels and the number of second pixels in each pixel group, the position of the second pixel can be switched in different image frames so that the number of second pixels in the same pixel group in different image frames remains unchanged, but the position changes. For example, when 6 pixels in the same row are divided into a pixel group, if the number of second pixels in the pixel group is determined to be 1, the pixel position of the second pixel can be changed in different image frames. The pixel position of the second pixel can be moved in a circular manner to the left or right every one or more image frames, or the second pixel can be randomly moved among the six pixel positions.

[0122] In the above embodiment, it is understood that if the ratio of interfering pixels does not change between different image frames, the number of second pixels within the same pixel group remains unchanged. In this case, only the pixel positions of the second pixels change between different image frames. However, if the ratio of interfering pixels changes between different image frames, the number of second pixels within the same pixel group will also change with the ratio of interfering pixels. In this case, the number of second pixels within the same pixel group will also change accordingly between different image frames.

[0123] As an optional embodiment, the above S1220 may include:

[0124] The number of first pixels and the number of second pixels are determined according to the number of pixels in each pixel group, so that the ratio of the number of second pixels to the number of first pixels is equal to the interference pixel ratio.

[0125] In this embodiment, after determining the interference pixel ratio, the number of first pixels and the number of second pixels can be determined based on the number of pixels in each pixel group, so that the ratio of the number of second pixels to the number of first pixels is equal to the interference pixel ratio. For example, when the number of pixels in a pixel group is 6 and the interference pixel ratio is 1:5, the number of first pixels can be determined to be 5 and the number of second pixels can be determined to be 1. In this case, the ratio of the number of second pixels to the number of first pixels is equal to the interference pixel ratio. In another example, when the number of pixels in a pixel group is 12 and the interference pixel ratio is 1:5, the number of first pixels can be determined to be 10 and the number of second pixels can be determined to be 2.

[0126] It is understood that the above-mentioned interference pixel ratio may be the ratio of the first pixel to the total number of pixels in the pixel group, or the above-mentioned interference pixel ratio may be the ratio of the second pixel to the total number of pixels in the pixel group. Based on the specific corresponding relationship represented by the interference pixel ratio, the number of the first pixel and the number of the second pixel can be determined respectively according to the total number of pixels in the pixel group.

[0127] In S1130 , after determining the corresponding plurality of first pixels and the plurality of second pixels in each image frame, the display panel may provide corresponding first data signals to the plurality of first pixels, and provide corresponding second data signals to the plurality of second pixels.

[0128] Since each row of pixels is driven row by row in each image frame using a row scanning drive method, taking one row of pixels as an example, the driver chip of the display panel can determine the first pixel and the second pixel in the row of pixels, and when the shift register unit corresponding to the row of pixels outputs a scan signal, the driver chip outputs the corresponding first data signal through the data signal output end corresponding to each first pixel, and outputs the corresponding second data signal through the data signal output end corresponding to each second pixel. Then, multiple first pixels in the row of pixels display a normal image, and multiple second pixels display an interference image. For each row of pixels, the driver chip can provide the first data signal to the first pixel in the row of pixels and the second data signal to the second pixel in the row of pixels when the shift register unit corresponding to each row of pixels outputs a scan signal.

[0129] As an optional embodiment, the display panel may be provided with a camera area for accommodating a camera, and the camera area may be provided with a front camera. Before S1110, the following steps may also be included:

[0130] In response to a user-triggered anti-peeping instruction, entering a second mode;

[0131] Alternatively, when the number of faces recognized by the front camera is greater than 1, the second mode is entered.

[0132] In this embodiment, the display panel may be provided with a camera area for accommodating a camera, and the camera area may be provided with a front-facing camera, which can capture images in the direction of light emission from the display panel. In a first mode, the display panel may use each pixel in each image frame as a first pixel to normally display image content. In the first mode, the display panel may enter a second mode when a pre-set condition is met, and in the second mode, each pixel in each image frame may be determined as a first pixel or a second pixel, so that a normal image is displayed through the first pixel and an interference image is displayed through the second pixel.

[0133] It is understood that the condition for entering the second mode can be that the user actively controls the display panel to enter the second mode, or the display panel enters the second mode upon detecting that a corresponding condition is currently met. For example, the user can control the display panel to enter the second mode by triggering an anti-peeping command, and the display panel can enter the second mode in response to the anti-peeping command.

[0134] The display panel can also capture the light emitting direction of the display panel through the front camera when not in the second mode to capture the user viewing the display panel. During the capture process, the display panel can also perform facial recognition based on the captured image and determine the number of faces in the image. When the number of recognized faces is greater than one, it indicates that there are two or more viewers in front of the display panel. At this time, the display panel can enter the second mode to display a mixed image of normal and interference images without affecting the viewer's normal viewing experience, preventing voyeurs from secretly capturing the image content of the display panel and causing leakage of the displayed content.
