[0021] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that throughout the accompanying drawings, the same elements are represented by the same or similar reference numerals. In the following description, some specific embodiments are used for descriptive purposes only and should not be construed as limiting this disclosure in any way, but are merely examples of embodiments of this disclosure. Conventional structures or configurations will be omitted where they may cause confusion in understanding this disclosure. It should be noted that the shapes and dimensions of the components in the figures do not reflect actual size and proportion, but are only schematic representations of the embodiments of this disclosure.

[0022] Unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure shall have the ordinary meaning as understood by those skilled in the art. The terms "first," "second," and similar words used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0023] Figure 1A , Figure 1B , Figure 1C , Figure 1D and Figure 1E This disclosure presents a schematic diagram of the structure of a display panel according to an embodiment. Figure 1A This shows the first display state of the display panel 100. Figure 1B and Figure 1D This shows the second display state of the display panel 100. Figure 1C and Figure 1E The third display state is shown.

[0024] For example, the display panel 100 may be a foldable display panel. The display panel 100 includes a first frame 101, a second frame 102, and a flexible display module 103. A pivot mechanism (not shown in the figure) is provided between the first frame 101 and the second frame 102, and the first frame 101 and the second frame 102 can rotate around the pivot mechanism to switch between an unfolded state and a folded state.

[0025] For example, the display panel 100 can be folded inwards and outwards. For example, the first frame 101 and the second frame 102 each have a first surface and a second surface. The flexible display module 103 is disposed on the first surface of the first frame 101 and the first surface of the second frame 102. In the inward folding mode, when the display panel 100 is folded, the first surface of the first frame 101 and the first surface of the second frame 102 are opposite surfaces when the first frame 101 and the second frame 102 are folded. In the outward folding mode, when the display panel 100 is folded, the second surface of the first frame 101 and the second surface of the second frame 102 are opposite surfaces when the first frame 101 and the second frame 102 are folded.

[0026] The flexible display module 103 includes a first display area 131 and a second display area 132. The first display area 131 is located in the first frame 101, and the second display area 132 is located in the second frame 102.

[0027] Figure 1A The first display state shown is the display state of the display panel 100 in the unfolded state. Figure 1B and Figure 1D The second display state shown is the display state of the display panel 100 in the folded state. Figure 1C and Figure 1E The third display state shown is the display state of the display panel 100 in the folded state. Among them, Figure 1A The diagram shows the unfolded state of the display panel 100, which is either an inward-folding display panel or an outward-folding display panel. Figure 1B and Figure 1C The image shows the display panel 100 in its folded state as an inward-folding display panel. Figure 1D and Figure 1E The image shows the display panel 100 in its folded state as an outward-folding display panel.

[0028] like Figure 1AAs shown, the display panel 100 is in a fully unfolded state, and the angle between the first surface of the first frame 101 and the first surface of the second frame 102 is 180°. The display panel 100 is in a first display state. In the first display state, all pixels in the first display area 131 and the second display area 132 are lit up.

[0029] like Figure 1B As shown, the display panel 100 is in a folded state. For example, when the angle between the first surface of the first frame 101 and the first surface of the second frame 102 is less than or equal to 90° and greater than 0°, and when the user is facing the first surface of the first frame 101, the display panel 100 is in a second display state. In the second display state, all pixels in the first display area 131 are lit up.

[0030] like Figure 1C As shown, the display panel 100 is in a folded state. For example, when the angle between the first surface of the first frame 101 and the first surface of the second frame 102 is less than or equal to 90° and greater than 0°, and the user is facing the first surface of the second frame 102, the display panel 100 is in a third display state. In the third display state, all pixels in the second display area 132 are lit up.

[0031] like Figure 1E As shown, the display panel 100 is in a folded state. For example, when the angle between the first surface of the first frame 101 and the first surface of the second frame 102 is greater than 270° and the user is facing the first surface of the first frame 101, the display panel 100 is in a second display state. In the second display state, all pixels in the first display area 131 are lit up.

[0032] like Figure 1E As shown, the display panel 100 is in a folded state. For example, when the angle between the first surface of the first frame 101 and the first surface of the second frame 102 is greater than 270° and the user is facing the first surface of the second frame 102, the display panel 100 is in a third display state. In the third display state, all pixels in the second display area 132 are lit up.

[0033] It should be noted that the angles between the first surfaces of the first frame 101 and the second frame 102 corresponding to the first, second, and third display states listed above are merely illustrative. This disclosure does not limit the range of angles corresponding to the first, second, and third display states. For different display panels, those skilled in the art can set the corresponding angle range according to actual needs. The scenarios described above are only illustrative of the situation where pixels in the display area of ​​the display panel 100 are lit in the first, second, and third display states.

[0034] Since the display area illuminated by the display panel 100 differs between the folded and unfolded states, the display quality of the display panel 100 also differs between the two states.

[0035] For example, the display panel 100 can be an Active Matrix Organic Light Emitting Diode (AMOLED) panel. During the manufacturing process of AMOLED panels, various process errors can cause inconsistent display brightness among different pixels, resulting in poor image quality. For example, dark stripes may appear in the displayed image.

[0036] Combination Figures 2A to 2C The display images for the first display state, the second display state, and the third display state are described. Figure 2A yes Figure 1A The diagram shown illustrates the displayed image on the display device. Figure 2B yes Figure 1B or Figure 1D The diagram shown illustrates the displayed image on the display device. Figure 2C yes Figure 1C or Figure 1E A schematic diagram of the image displayed on the display device. Figure 2A , Figure 2B and Figure 2C The display images of the display panel 100 in the first display state, the second display state, and the third display state are shown respectively.

[0037] For example, in the first display state, all pixels in the first display area 231 and the second display area 232 are lit up, and the position of the dark stripe S1 can be as follows: Figure 2A As shown. In the second display state, all pixels in the first display area 231 are lit, and the second display area 232 is a black screen. The position of the dark stripe S2 can be as shown. Figure 2B As shown. In the third display state, all pixels in the second display area 232 are lit, the first display area 231 is black, and the position of the dark stripe S3 can be as shown. Figure 2C As shown.

[0038] For example, to compensate for the brightness unevenness between pixels in the display panel 100, the driving signal applied to the display panel 100 can be adjusted using a "de-mura" process, thereby improving the display quality of the display panel 100. Before adjusting the driving signal using the "de-mura" process, the original display image of the display panel 100 needs to be determined. For example, Figures 2A to 2C The displayed image shown can be the original display image of the display panel 100 in different display states.

[0039] It should be noted that, Figures 2A to 2C The displayed image shown can be the image seen by the user through the display panel 100. For example, the display panel 100 can be captured by a large-area camera in different display states to obtain the display images of the display panel 100 in different display states.

[0040] like Figures 2A to 2C As shown, since the positions of the dark stripes in the displayed image are inconsistent under different display states, it is necessary to sample the display screen 100 under different display states to compensate for the different display states of the display screen 100. However, image compensation based on this sampling method suffers from long sampling times, which affects the compensation efficiency.

[0041] Based on the above problems, this disclosure proposes a method for determining compensation data, which samples only the display image of the display panel in the first display state, and uses the display image of the display panel in the first display state to determine the display image of the display panel in the second and third display states, thereby enabling compensation for the first, second, and third display states of the display panel, shortening the sampling time and improving the compensation efficiency.

[0042] Figure 3 This is a schematic diagram of the structure of a compensation data determination device according to an embodiment of the present disclosure.

[0043] like Figure 3 As shown, the compensation data determination device 300 includes a first processing unit 310 and a compensation unit 320.

[0044] In this embodiment of the present disclosure, the first processing unit 310 acquires a first image and determines a second image and a third image based on the target ratio parameter and the first image.

[0045] In this embodiment of the disclosure, the first image is obtained by an image acquisition device capturing a first display image of the display panel in a first display state. For example, the image acquisition device may be a large-area array camera. The second image and the third image are image data for the second and third display states of the display panel, respectively.

[0046] In this embodiment, the display panel is a foldable display panel. The first display state is the unfolded display state of the display panel, and the second and third display states are the folded display states of the display panel. The folded display states of the second and third display states are different, and the illuminated display areas of the display panel are different in the second and third display states. For example, the display panel can be... Figures 1A to 1D The display panel 100 is shown. The first display state can be... Figure 1A The first display state is shown; the second display state can be... Figure 1B and Figure 1D The third display state can be shown. Figure 1C and Figure 1E The displayed status is shown.

[0047] The first image is obtained by capturing the display screen of the display panel using an image acquisition device. The second and third images are calculated based on the first image. For example, the first image is obtained by capturing the first display screen of the display panel in its unfolded state using an image acquisition device. The second and third images can be display images of the display panel in its folded state, determined based on the first image.

[0048] In this embodiment of the disclosure, the target scale parameter is determined based on reference images of multiple reference display panels. The reference images are obtained by an image acquisition device capturing images of the display screens of the multiple reference display panels in a first display state, a second display state, and a third display state.

[0049] For example, the target scale parameter can characterize the pixel value relationship between the first, second, and third images. Therefore, based on the pixel values ​​of the first image, the pixel values ​​of the second and third images can be calculated.

[0050] For example, multiple reference display panels and the display panel can be display panels of the same model produced in the same batch, and multiple reference display panels and the display panel have the same display parameters and size parameters.

[0051] For example, for multiple display panels of the same batch and model, several display panels can be selected as reference display panels, and a target scale parameter can be determined based on these reference display panels. Using the target scale parameter and the first image of each of the multiple display panels in the batch, the second and third images of each of the multiple display panels in the batch are calculated.

[0052] For example, a batch of display panels may include thousands of display panels. Multiple reference panels may be three display panels selected from that batch. This disclosure does not limit the number of reference display panels.

[0053] In this embodiment of the disclosure, the compensation unit 320 generates first compensation data, second compensation data, and third compensation data based on the first image, the second image, and the third image.

[0054] For example, dark stripes exist in the first, second, and third images. Based on the dark stripes in each of the first, second, and third images, first compensation data, second compensation data, and third compensation data are generated respectively to eliminate the dark stripes in the first, second, and third images, thereby improving the image display quality of the display panel in the first, second, and third display states.

[0055] In this embodiment of the disclosure, the first compensation data, the second compensation data, and the third compensation data are used to determine the data driving signals of the display panel for the first display state, the second display state, and the third display state, respectively.

[0056] For example, the first compensation data can be the compensation value of the data drive signal applied to the display panel in the first display state. By compensating the voltage value of the data drive signal applied to the pixel circuit, the display brightness of the pixels is optimized, thereby eliminating dark stripes in the first display image of the display panel in the first display state and making the brightness of the first display image uniform.

[0057] In this embodiment, by sampling only the display screen of the display panel in the first display state, and determining the display screen of the display panel in the second and third display states based on the sampled first image, a second image and a third image are obtained. This allows the first, second, and third images of the display panel for the first, second, and third display states to be obtained with only one sampling. Therefore, compensation for the display screen of the display panel in the first, second, and third display states can be performed based on the first, second, and third images, shortening the sampling time and improving compensation efficiency.

[0058] Figure 4 This is a schematic diagram of the structure of a compensation data determination device according to another embodiment of the present disclosure.

[0059] like Figure 4 As shown, the compensation data determination device 400 includes a first processing unit 410, a compensation unit 420, and a second processing unit 430.

[0060] In this embodiment, the first processing unit 410 and the compensation unit 420 are similar to the first processing unit 310 and the compensation unit 320 described above, and will not be repeated for the sake of brevity.

[0061] For example, the first processing unit 410 can be hardware such as a graphics card, the compensation unit 420 can be a de-mura module in a display driver chip, and the second processing unit 430 can be a microcontroller unit (MCU). The first processing unit 410 and the second processing unit 430 can be integrated into one piece of hardware, or they can be set up independently.

[0062] In this embodiment of the present disclosure, the second processing unit 430 acquires reference images of each of the multiple reference display panels, the reference images including a first reference image, a second reference image and a third reference image, and stitches together the second reference image and the third reference image of each of the multiple reference display panels to obtain a reference stitched image of each of the multiple reference display panels; and determines a target ratio parameter based on the ratio relationship between the reference stitched image of each of the multiple reference display panels and their respective first reference images.

[0063] In this embodiment of the disclosure, the first reference image, the second reference image, and the third reference image are obtained by the image acquisition device capturing the first reference display screen of multiple reference display panels in a first display state, the second reference display screen in a second display state, and the third reference display screen in a third display state, respectively.

[0064] In the embodiments of this disclosure, the first reference image, the second reference image, and the third reference image can all be obtained by capturing the display screen of the display panel in the unfolded state.

[0065] The first reference image is captured by the image acquisition device of pixels in the first and second illuminated display areas of the display panel in its unfolded state. The second reference image is captured by the image acquisition device of pixels in the first illuminated display area of ​​the display panel in its unfolded state. The third reference image is captured by the image acquisition device of pixels in the second illuminated display area of ​​the display panel in its unfolded state. The first and second display areas are different areas of the display panel.

[0066] For example, in the unfolded state of the display panel, all pixels of the display panel are illuminated, and an image acquisition device is used to capture first reference display images of multiple reference display panels, resulting in first reference images of multiple reference display panels. Alternatively, in the unfolded state of the display panel, pixels located in the first display area of ​​the display panel are illuminated to simulate a second display state of the display panel. In this case, the display image of the display panel is the second reference display image, and an image acquisition device is used to capture the second reference display images of multiple reference display panels, resulting in second reference images of multiple reference display panels.

[0067] For example, when the display panel is in its unfolded state, the pixels located in the second display area of ​​the display panel are illuminated to simulate the third display state of the display panel. At this time, the display screen of the display panel is the third reference display screen. Multiple reference display screens are captured by an image acquisition device to obtain multiple third reference images of the reference display panels.

[0068] For example, in the unfolded state of the display panel, driving signals are provided to all pixels of the display panel, making the brightness matrix of the display panel (255, 255, 255), thereby acquiring first reference data. In the unfolded state of the display panel, driving signals are provided to pixels located within a first display area of ​​the display panel, making the brightness matrix of the first display area (255, 255, 255), thereby acquiring second reference data. In the unfolded state of the display panel, driving signals are provided to pixels located within a second display area of ​​the display panel, making the brightness matrix of the second display area (255, 255, 255), thereby acquiring third reference data.

[0069] Combination Figure 5A and Figure 5B The first reference image and the reference stitched image are illustrated schematically.

[0070] Figure 5A This is a schematic diagram based on a first reference image according to an embodiment of the present disclosure.

[0071] like Figure 5A As shown, by illuminating all pixels of the display panel in its unfolded state and capturing an image of the reference display panel using an image acquisition device, a first original reference image 501 of the reference display panel is obtained. The first original reference image 510 may include a first reference display screen and a non-display area of ​​the display panel. The first reference display screen in the first original reference image 510 is the valid portion; therefore, by cropping the first reference display screen from the first original reference image 510, a first reference image whole is obtained.

[0072] Figure 5B This is a schematic diagram of a reference image stitched together according to an embodiment of the present disclosure.

[0073] like Figure 5B As shown, in the unfolded state of the display panel, the pixels located in the first display area of ​​the display panel are illuminated, and the reference display panel is photographed using an image acquisition device to obtain a second original reference image 502 of the reference display panel. In the second original reference image 502, the second reference display screen 521 is the valid portion, and the second screen to be displayed 522 is a black screen. In the unfolded state of the display panel, the pixels located in the second display area of ​​the display panel are illuminated, and the reference display panel is photographed using an image acquisition device to obtain a second original reference image 503 of the reference display panel. In the second original reference image 503, the third reference display screen 532 is the valid portion, and the third screen to be displayed 531 is a black screen. The second reference display screen 521 is cropped from the second original reference image 502, and the third reference display screen 532 is cropped from the second original reference image 503 and then stitched together to obtain a reference stitched image concat.

[0074] In this embodiment, the splicing method between the second reference display screen 521 and the third reference display screen 532 is related to the first reference display screen, and the size of the spliced ​​image obtained from the second reference display screen 521 and the third reference display screen 532 is the same as the size of the first reference display screen. Therefore, the first reference image whole and the reference spliced ​​image concat have the same image size.

[0075] For example, splicing the second reference display screen 521 and the third reference display screen 532 can be considered as using the third reference display screen 532 to cover the second screen to be displayed 522 in the second original reference image 502, thus obtaining a reference spliced ​​image concat. Similarly, splicing the second reference display screen 521 and the third reference display screen 532 can be considered as using the second reference display screen 521 to cover the third screen to be displayed 531 in the second original reference image 503, thus obtaining a reference spliced ​​image concat.

[0076] For example, the size of the first reference display screen is 12cm*6cm, the size of the second reference display screen 521 is 6cm*6cm, the size of the third reference display screen 532 is 6cm*6cm, and the size of the screen obtained by splicing the second reference display screen 521 and the third reference display screen 532 is 12cm*6cm.

[0077] In some embodiments, the second processing unit 430 determines the reference ratio parameters of each of the multiple reference display panels based on the ratio relationship between the reference stitched image of each of the multiple reference display panels and the first reference image; and determines the target ratio parameters based on the multiple reference ratio parameters and their respective weights.

[0078] In this embodiment of the disclosure, since there are differences in the display quality of each reference display panel, the weights of the multiple reference display panels can be determined based on their respective display quality.

[0079] For example, when the display quality differences between multiple reference display panels are small, the same weight can be assigned to all reference display panels. When the display quality of one reference display panel is significantly worse than that of the remaining display panels, the reference ratio parameter of that reference display panel can be ignored, and the target ratio parameter can be determined based on the reference ratio parameters of the remaining display panels.

[0080] For example, when the display quality difference between multiple reference display panels is small, the average of multiple reference scale parameters of the multiple reference display panels can be used as the target scale parameter.

[0081] In this embodiment of the disclosure, the reference ratio parameters of each of the multiple reference display panels can be determined based on the proportional relationship between the pixel values ​​of the reference stitched images of each of the multiple reference display panels and the pixel values ​​of the first reference image.

[0082] In some embodiments, the second processing unit 430 determines multiple pixel ratio values ​​for each of the multiple reference display panels based on the reference stitched images of each of the multiple reference display panels and the first reference image, wherein the pixel ratio value is the ratio of the pixel value of the reference stitched image of the reference display panel to the pixel value of the same pixel point of the reference display panel in the first reference image, and the multiple pixel ratio values ​​correspond one-to-one with the multiple pixels included in each of the multiple reference display panels; and determines reference ratio parameters for each of the multiple reference display panels based on the multiple pixel ratio values ​​of each of the multiple reference display panels.

[0083] For example, the pixel ratio value of each pixel is determined based on the pixel values ​​of the multiple pixels included in the first reference image and the pixel values ​​of the multiple pixels included in the reference stitched image.

[0084] For example, the pixel ratio value of a pixel can be determined by using the ratio between the pixel value of a pixel in the first row and first column of the first reference image and the pixel value of a pixel in the first row and first column of the reference stitched image.

[0085] For example, the reference scale parameter of the reference display panel can be determined by equation (1):

[0086]

[0087] in, This represents the reference scale parameter of the i-th reference display panel among multiple reference display panels. This represents the image data of the reference stitched image of the i-th reference display panel among multiple reference display panels. This represents the image data of the first reference image of the i-th reference display panel among multiple reference display panels, where i is a positive integer.

[0088] In this embodiment of the disclosure, pat represents the display image at any grayscale level. For example, and It can be obtained by displaying any grayscale image on the display panel. The first reference image and the reference stitched image are obtained based on the display images under the same grayscale. For example, the first reference image and the reference stitched image can be obtained by displaying a grayscale image (255, 255, 255) on the display panel in the corresponding display state. The first reference image and the reference stitched image can also be obtained by displaying a grayscale image (127, 127, 127) on the display panel in the corresponding display state.

[0089] For example, It can represent the pixel values ​​(or grayscale values, or brightness values) of multiple pixels in the reference mosaic image of the i-th reference display panel among multiple reference display panels. It can be the image data of the reference stitching image of the i-th reference display panel, represented in matrix form. This refers to the pixel values ​​(or grayscale values, or brightness values) of each pixel point in the first reference image of the i-th reference display panel among multiple reference display panels. It can be the image data of the first reference image of the i-th reference display panel, represented in matrix form. It can be represented in matrix form as the pixel ratio values ​​of multiple pixels of the i-th reference display panel.

[0090] In this embodiment of the disclosure, since the first reference image whole and the reference stitched image concat have the same image size, therefore and These are matrices of the same dimension. For example, the image data of the first reference image. The image data of the second and third reference images are both 50×100 matrices, and the image data of the reference stitched image are also 50×50 matrices. It is a 50×100 matrix. Equation (1) represents and The value in the middle represents the result of dividing the pixel value of the same pixel on the reference display panel. The value in the matrix represents the pixel ratio of that pixel. Therefore, the reference ratio parameter is also a 50×100 matrix.

[0091] An example is a 2×2 matrix, for instance,

[0092] For multiple reference display panels, the target scaling parameter can be determined by equation (2):

[0093]

[0094] Where, ratio pat This represents the target scale parameter. 'n' represents the number of reference panels, for example, n = 3.

[0095] For example, when there is a reference scale parameter for a reference display panel. Much larger or much smaller than the reference scale parameter of the remaining reference display panels among multiple reference display panels The reference scale parameter of this reference display panel can be ignored. And use the reference scale parameters of the remaining reference display panel. The mean is used as the target ratio parameter. pat .

[0096] Combination Figure 5C The reference scale parameters are illustrated. Figure 5C This is a schematic diagram of reference scaling parameters according to embodiments of the present disclosure.

[0097] matrix sum matrix The elements represent the brightness of the pixels at the corresponding positions in the display panel under the corresponding states, and the matrix... The elements in the matrix represent the ratio of brightness between two states for the corresponding pixel on the display panel. matrix sum matrix like Figure 5C As shown.

[0098] Figure 6 This is a schematic diagram illustrating the determination of the second and third images according to embodiments of the present disclosure.

[0099] like Figure 6 As shown, the first processing unit determines the original spliced ​​image Ps of the display panel based on the target ratio parameter and the first image P1, and splits the original spliced ​​image Ps according to the positional relationship between the display screens of the display panel in the second display state and the third display state to obtain the second image P2 and the third image P3.

[0100] In this embodiment of the present disclosure, the positional relationship between the display screens of the display panel in the second display state and the third display state reflects the positional relationship between the second image P2 and the third image P3, and the positional relationship between the second image P2 and the third image P3 corresponds to the positional relationship between the second reference image and the third reference image in the reference stitched image.

[0101] For example, since the display panel and the reference display panel are of the same model and from the same batch, the first reference display screen of the reference display panel has the same size as the first display screen of the display panel. Because the target scale parameter is determined based on the reference display panel, the image size of the original stitched image Ps, determined according to the target scale parameter and the first image P1, is the same as the size of the reference stitched image. Based on the stitching method between the second and third reference images in the reference stitched image, splitting the original stitched image Ps yields the second image P2 and the third image P3.

[0102] Therefore, the size of the spliced ​​display screen is the same as the size of the first display screen. The spliced ​​display screen is the screen obtained by splicing the second display screen in the second display state and the third display screen in the third display state. The first display screen is the display screen of the display panel in the first display state, the second display screen is the display screen of the display panel in the second display state, and the third display screen is the display screen of the display panel in the third display state.

[0103] In this embodiment of the present disclosure, the first processing unit uses a target ratio parameter and a first image P1 to determine the stitched pixel value of a plurality of pixels included in the display panel. The target ratio parameter includes the target pixel ratio value of each of the plurality of pixels included in the display panel. The stitched pixel value is the product of the pixel value of the pixel in the first image P1 and the target pixel ratio value of the pixel in the target ratio parameter. The processing unit also arranges the stitched pixel values ​​of the plurality of pixels according to the positional relationship of the plurality of pixels in the display panel to obtain the original stitched image.

[0104] For example, the pixel value of a pixel in the original stitched image is determined by multiplying the pixel value of the pixel in the first image with the target pixel ratio value of the pixel in the target ratio parameter. For example, the pixel value of the pixel in the first row and first column of the first image is calculated by multiplying the pixel value of the pixel in the first row and first column of the target ratio parameter.

[0105] For example, the original stitched image can be determined by equation (3):

[0106] predict pat =ratio pat whole pat (3)

[0107] Among them, predict pat The ratio represents the image data of the original stitched image. pat The whole represents the target scaling parameter obtained through equation (2). pat Image data representing the first image of the display panel.

[0108] For example, predict pat It can represent the individual pixel values ​​(or grayscale values, or brightness values) of multiple pixels in the original mosaic image of the display panel. pat This can be image data representing a reference mosaic image of the display panel in matrix form. pat This refers to the pixel values ​​(or grayscale values, or brightness values) of the individual pixels comprising the first image of the display panel. pat It can be image data that represents the first reference image of the display panel in matrix form.

[0109] In this embodiment of the disclosure, since the first image P1 and the original stitched image Ps have the same image size, therefore predicting... pat with whole pat These are matrices of the same dimension. For example, the whole image data of the first image P1. pat The image data predict of the original stitched image Ps is a 50×100 matrix. pat It is also a 50×100 matrix. The image data of the original stitched image Ps is predicted. pat By splitting the image, we can obtain the image data of the second image P2 and the third image P3. Similar to the second and third reference images, the image data of the second image P2 and the third image P3 are both 50×50 matrices.

[0110] Equation (3) represents ratiio pat with whole pat The value in the middle represents the pixel ratio of the same pixel on the display panel multiplied by the pixel value, resulting in the prediction. pat The value in the text represents the pixel value of that pixel.

[0111] An example is a 2×2 matrix, for instance,

[0112] In this disclosed embodiment, predict pat As the original display image of the display panel in the folded state, the first processing unit obtains the image from the predicted image. patThe second and third images were separated from the whole image. pat The first image is the original display image of the display panel in its unfolded state. Based on the first image, the second image, and the third image, the compensation unit can determine the first compensation data, the second compensation data, and the third compensation data using a compensation process.

[0113] By using the embodiments of this disclosure, compensation data is determined using the method provided in this disclosure, and the compensation data is used to perform image compensation on the display panel, thereby eliminating the problem of uneven brightness in the display screen of the display panel.

[0114] In this embodiment, the first image of the display panel is acquired by an image acquisition device, and the second and third images of the display panel are calculated based on the first image. The first image acquired by the image acquisition device is used to compensate for the display screen in its unfolded state, and the second and third images calculated based on the first image are used to compensate for the display screen in its folded state. The second and third images are related to the first image, and there is a mapping relationship between them. The data quality of the second and third images is affected by the data quality of the first image. Therefore, the compensation effect of the second and third compensation data on the folded state of the display panel is affected by the data quality of the first image.

[0115] Furthermore, if the second and third images of the display panel are directly acquired using an image acquisition device and then stitched together to obtain a stitched image, the stitching points between the second and third images in the stitched image represent their respective edges. Since the second and third images are acquired independently, the correlation between the pixel values ​​representing the edges of the second and third images in the stitched image is relatively small.

[0116] In this embodiment of the disclosure, the original stitched image is calculated from the first image. Although the original stitched image represents the stitching result of the second and third images, since there is no stitching point in the first image, there is also no stitching point in the original stitched image. Therefore, the pixels representing the edges of the second and third images in the original stitched image have a high correlation.

[0117] In this embodiment, a first image, a second image, and a third image that are correlated with each other can be obtained through a single sampling. Based on these correlated images, image compensation is performed on the first display state, the second display state, and the third display state, respectively. Compared to sampling the first, second, and third display states of the display panel separately, the compensation data determination device provided in this disclosure reduces the sampling time by two-thirds, improving compensation efficiency. Furthermore, the compensation data determination device provided in this disclosure can be set up independently of the display panel, thus eliminating the need for additional investment in the De-mura process during the display panel design and manufacturing process, thereby reducing the manufacturing cost of the display panel.

[0118] Figure 7 This is a schematic diagram of the structure of a display device according to an embodiment of the present disclosure.

[0120] In this embodiment of the disclosure, the compensation device 710 compensates the original image to be displayed using compensation data to obtain the image to be displayed.

For example, it can be determined by the compensation data determining device 300 or the compensation data determining device 400 provided in this embodiment of the disclosure. For example, the compensation data may include first compensation data, second compensation data, and third compensation data.

[0121] In this embodiment of the disclosure, the display panel 720 displays an image to be displayed. After the display panel 720 displays the image to be displayed, the uniformity of the brightness of the display panel 720 is improved.

[0126] In step S820, the second image and the third image are determined based on the target scale parameter and the first image.

[0127] In step S830, based on the first image, the second image, and the third image, first compensation data, second compensation data, and third compensation data are obtained.

[0128] In this embodiment of the disclosure, the second image and the third image are image data for the second and third display states of the display panel, respectively. The target ratio parameter is determined based on reference images of multiple reference display panels. The reference images are obtained by capturing the display screens of multiple reference display panels in the first, second, and third display states. The first compensation data, the second compensation data, and the third compensation data are used to determine the data driving signals of the display panel for the first, second, and third display states, respectively.
