[0037] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this application without making creative efforts are within the scope of protection of this application.

[0038] In the following description, the terms "first\second" are only used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first\second" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0040] Reference Figure 1 , Figure 1 A flow chart of a display method proposed in one embodiment of the present application is shown. The method is used for a display device and includes:

[0041] S110 : When the display mode is the compensation mode, receive a compensation image corresponding to the image to be displayed.

[0042] Among them, the compensation image is obtained by splicing multiple sub-compensation images corresponding to the image to be displayed; one sub-compensation image corresponds to a frame display period, and the sub-compensation image includes the first luminous grayscale of each luminous pixel in the display panel within the frame display period corresponding to the sub-compensation image; in the compensation mode, each display pixel corresponds to multiple luminous pixels, and the multiple luminous pixels corresponding to the display pixel emit light in their respective corresponding frame display periods to provide brightness for the display pixel; the first luminous grayscale of the luminous pixel in each frame display period is determined according to the display grayscale of the display pixel corresponding to the luminous pixel in the image to be displayed.

[0043] In the present application, the display device has a display panel, and each pixel in the display panel serves as a light-emitting pixel. For example, the display panel may be a uLED display panel or a MicroLED display panel. In some embodiments, the display panel is a single-color channel display panel, and a light-emitting pixel may refer to a light-emitting pixel under a single color channel, wherein a single color channel may refer to a red channel, a blue channel, or a green channel. For example, in a red display panel, a light-emitting pixel may refer to a light-emitting pixel under a red channel. In other embodiments, the display panel is a color display panel (the display panel includes light-emitting pixels under different color channels), and the light-emitting pixel may include light-emitting pixels of multiple single color channels. For example, the display panel may include red light-emitting pixels under a red channel, blue light-emitting pixels under a blue channel, and green light-emitting pixels under a green channel.

[0044] In this embodiment, the display panel may be a display panel having a pixel shift device (for example, a device in XPR shift technology that can change the optical path of the light beam emitted by the light-emitting pixels of the panel or the light-emitting units of the DMD, thereby achieving pixel shift).

[0045] In this embodiment, when a pixel in the display panel emits light, the pixel shifting device also shifts, thereby changing the optical path of the pixel. This allows light emitted by multiple pixels to be incident on the same display position along the changed optical path. This display position then serves as the display pixel corresponding to the multiple pixels. This means that the display effect of any display pixel in the image to be displayed is the result of the combined effect of the multiple pixels corresponding to the display pixel. In other words, the brightness of any display pixel in the image to be displayed is provided by the multiple pixels corresponding to the display pixel. One pixel in the image to be displayed serves as a display pixel. In other words, each pixel on the display panel emits light according to a specified grayscale value to display a specified brightness. Simultaneously, the pixel shifting device changes the propagation direction of the optical paths of these pixels, shifting the light emitted by the multiple pixels to the same display pixel in a time-sharing manner.

[0046] In this application, grayscale can be indicated by grayscale values. Grayscale values can be 4-bit, 8-bit, or 16-bit data. For example, when the grayscale value is 4 bits, the grayscale value includes 15 grayscale values from 0 to 15. The grayscale range involved can be divided according to requirements to obtain multiple grayscale ranges, and each grayscale range is indicated by a grayscale value.

[0047] It is worth mentioning that, when the pixel shifting device in this embodiment shifts, it moves the optical path of the multiple luminescent pixels corresponding to each display pixel to the position where the display pixel is located. In other words, the purpose of the pixel shifting device is to change the optical path of the multiple luminescent pixels corresponding to each display pixel so that the light emitted by the multiple luminescent pixels corresponding to each display pixel can be incident on the same display pixel position along the changed optical path.

[0048] For example, consider a single display pixel whose brightness is provided by four luminescent pixels. The luminescent pixels on the backplane of the display panel change the direction of the light path through a pixel offset device, so that the light path of the same luminescent pixel moves to different positions in the image plane. The duration of a frame is used as a cycle, and each cycle is divided into frame display periods corresponding to the four luminescent pixels. The frame display period of a luminescent pixel refers to the period within a frame during which the luminescent pixel emits light. In other words, the display duration of a frame is divided into four frame display periods.

[0049] like Figure 2 As shown, during the first frame display period, the light paths of the A, B, C, and D luminous pixels on the backplane 301 move to a1, b1, c1, and d1 in the image plane 303 after passing through the pixel shift device 302, and a0, b0, c0, and d0 are the respective positions of the light paths of the A, B, C, and D luminous pixels when propagating along a straight line.

[0050] like Figure 2As shown, during the second frame display period, the light paths of the A, B, C, and D luminous pixels on the back panel 301 move to a2, b2, c2, and d2 in the image plane 303 after passing through the pixel shift device 302, and a0, b0, c0, and d0 are the respective positions of the light paths of the A, B, C, and D luminous pixels when propagating along a straight line.

[0051] like Figure 4 As shown, during the third frame display period, the light paths of the A, B, C, and D luminous pixels on the back panel 301 move to a3, b3, c3, and d3 in the image plane 303 after passing through the pixel shift device 302, and a0, b0, c0, and d0 are the respective positions of the light paths of the A, B, C, and D luminous pixels when propagating along a straight line.

[0052] like Figure 5 As shown, during the fourth frame display period, the light paths of the A, B, C, and D luminous pixels on the back panel 301 move to a4, b4, c4, and d4 in the image plane 303 after passing through the pixel shift device 302, and a0, b0, c0, and d0 are the respective positions of the light paths of the A, B, C, and D luminous pixels when propagating along a straight line.

[0053] like Figure 6 As shown, Figure 6 a in FIG. 1 shows a case where one display pixel corresponds to four luminescent pixels, that is, luminescent pixels e61 , e62 , e63 , and e64 provide brightness for display pixel e60 ; Figure 6 b in FIG. 5 shows a situation where one display pixel corresponds to two luminous pixels, that is, the luminous pixels e65 and e66 provide brightness for the display pixel e67.

[0054] In an embodiment of the present application, the display mode of the display device may include a compensation mode, a super-resolution mode, and a super-resolution compensation mode. The user can set the display mode of the display device based on needs. For example, the user can send a mode switching command through the remote control to switch the display mode of the display device to the compensation mode.

[0055] In this embodiment, the display device may include a SOC (System on Chip) and an FPGA (Field Programmable Gate Array). The SOC has higher computing power than the FPGA. The SOC can generate a compensation image based on the image to be displayed, and then the FPGA executes the step of controlling the display panel to emit light based on the compensation image (i.e., steps S110-S140 in this embodiment).

[0056] In this embodiment, the image to be displayed may refer to any screen or image to be displayed, and may be a video frame, an image, or a document screen, etc. The size of the image to be displayed is the same as the size of the display panel. For example, if the size of the display panel is m*n (including m*n luminous pixels), the size of the image to be displayed is also m*n (including m*n display pixels).

[0057] When the display mode of the display device is the compensation mode, the SOC can obtain the image to be displayed, and then for each display pixel in the image to be displayed, the first luminous grayscale of each luminous pixel corresponding to the display pixel in each frame display period is determined according to the display grayscale of the display pixel, and then multiple sub-compensated images are generated according to the first luminous grayscale of each luminous pixel in each frame display period, and then the multiple sub-compensated images are spliced into one image to obtain a compensated image.

[0058] In some embodiments, a method for obtaining a compensated image includes: determining the first luminous grayscale of multiple luminous pixels corresponding to each display pixel within their respective frame display periods based on the display grayscale, maximum adjustment brightness, and maximum displayable brightness corresponding to each display pixel; constructing an image based on the first luminous grayscale corresponding to each luminous pixel in the same frame display period to obtain a sub-compensated image corresponding to each frame display period; and splicing multiple sub-compensated images to obtain a compensated image.

[0059] The maximum adjusted brightness corresponding to a display pixel can be a brightness value set as needed and not greater than the maximum brightness corresponding to the display pixel. The maximum brightness corresponding to a display pixel can refer to the maximum brightness value of the display pixel under the action of multiple normally emitting pixels. In this embodiment, the brightness value of the display pixel can be indicated by 0-255. That is, if the maximum brightness corresponding to the display pixel is 255, the maximum adjusted brightness corresponding to the display pixel can be a value not greater than 255, such as 160 or 180. The maximum adjusted brightness corresponding to different display pixels can be the same.

[0060] The maximum displayable brightness corresponding to a display pixel may refer to the maximum brightness value that the display pixel can display. A method for obtaining the maximum displayable brightness corresponding to a display pixel may include: obtaining actual brightness values of each of the multiple luminous pixels corresponding to the display pixel when controlling the multiple luminous pixels corresponding to the display pixel to emit light at maximum luminous power; and performing a weighted summation of the actual brightness values of the multiple luminous pixels corresponding to the display pixel to obtain the maximum displayable brightness corresponding to the display pixel. The weights of the multiple luminous pixels corresponding to the display pixel may be the same, that is, the average of the actual brightness values of the multiple luminous pixels corresponding to the display pixel is the maximum displayable brightness corresponding to the display pixel.

[0061] It is understandable that, at this time, the process of determining the maximum displayable brightness corresponding to the display pixel can be briefly described as Formula 1, which is as follows:

[0062]

[0063] Wherein, n is the number of the plurality of luminous pixels corresponding to the display pixel, n is an integer greater than 1, and x i is the actual brightness value of the i-th luminous pixel among the multiple luminous pixels corresponding to the display pixel, and y is the maximum displayable brightness of the display pixel.

[0064] It should be noted that for a normal luminous pixel, when the pixel emits light at maximum luminous power, the grayscale value of the pixel's light is the maximum luminous grayscale value (that is, the maximum luminous grayscale value corresponding to each luminous pixel in the display panel of this application is the same); however, for a defective pixel, when it emits light at maximum luminous power, the grayscale value of the pixel is lower than the maximum luminous grayscale value, and the actual brightness value of the defective pixel is lower than the actual brightness value of the normal luminous pixel. That is, although the defective pixel also emits light at maximum luminous power, the grayscale value of the light emitted is lower than the maximum luminous grayscale value, and the actual brightness value is lower.

[0065] It can be understood that the multiple luminous pixels corresponding to different display pixels may be different, and the actual brightness values of different luminous pixels when emitting light at maximum luminous power may be different. The maximum displayable brightness corresponding to the display pixel is determined based on the actual brightness values of the multiple luminous pixels corresponding to the display pixel. Therefore, the maximum displayable brightness corresponding to different display pixels may be different.

[0066] Optionally, determining the first luminous grayscale of the multiple luminous pixels corresponding to each display pixel within their respective frame display periods based on the display grayscale, maximum adjusted brightness, and maximum displayable brightness corresponding to each display pixel may include: if the maximum displayable brightness corresponding to the display pixel is not greater than the maximum adjusted brightness, obtaining the display grayscale corresponding to the display pixel as the first luminous grayscale of the multiple luminous pixels corresponding to the display pixel within their respective frame display periods.

[0067] For any display pixel, if the maximum displayable brightness corresponding to the display pixel is not greater than the maximum adjusted brightness of the display pixel, the display grayscale corresponding to the display pixel is directly used as the first luminous grayscale of the multiple luminous pixels corresponding to the display pixel in their respective frame display periods. In this case, there exists k1=k2=k3=...=k n =k y , where k1-k n k refers to the first luminous grayscale of the luminous pixel corresponding to the display pixel in the respective frame display period, y is the display grayscale of the display pixel.

[0068] Optionally, determining the first luminous grayscale of multiple luminous pixels corresponding to each display pixel within their respective frame display periods based on the display grayscale, maximum adjusted brightness, and maximum displayable brightness corresponding to each display pixel may also include: if the maximum displayable brightness corresponding to the display pixel is greater than the maximum adjusted brightness, dividing the multiple luminous pixels corresponding to the display pixel into multiple pixel groups; determining the maximum adjusted display grayscale corresponding to the display pixel based on the maximum luminous grayscale corresponding to the luminous pixel in the display panel, the number of multiple pixel groups corresponding to the display pixel, the maximum adjusted brightness, and the maximum displayable brightness; determining the mapping value corresponding to the display pixel based on the maximum luminous grayscale, the maximum adjusted display grayscale corresponding to the display pixel, and the display grayscale; and determining the first luminous grayscale of each luminous pixel in each pixel group corresponding to the display pixel within their respective frame display periods based on the maximum luminous grayscale and the mapping value corresponding to the display pixel.

[0069] If the maximum displayable brightness corresponding to the display pixel is greater than the maximum adjusted brightness, it is determined that the display grayscale corresponding to the display pixel cannot be directly used as the first emission grayscale of the multiple luminescent pixels corresponding to the display pixel within their respective frame display periods. In this case, the multiple luminescent pixels corresponding to the display pixel can be divided into multiple pixel groups, each pixel group including two luminescent pixels.

[0070] As an implementation method, the multiple luminous pixels corresponding to the display pixel can be arranged in descending order according to the actual luminous brightness value to obtain a luminous pixel sequence corresponding to the display pixel, and the p-th luminous pixel and the (qp)-th luminous pixel in the luminous sequence corresponding to the display pixel are divided into a pixel group, so that the multiple luminous pixels corresponding to the display pixel are divided into multiple pixel groups, and q starts from 1 until all display pixels in the luminous sequence corresponding to the display pixel are traversed, and q is the total number of luminous pixels in the luminous sequence corresponding to the display pixel.

[0071] For example, the display pixel x1 corresponds to four luminous pixels f1, f2, f3 and f4, and the actual brightness values of the four luminous pixels f1, f2, f3 and f4 are i1, i2, i3 and i4 respectively. The luminous pixel sequence corresponding to the display pixel x1 is determined to be f4-f1-f3-f2. Then, f4 and f2 are taken as a pixel value, and f3 and f1 are taken as a pixel group, to obtain two pixel groups.

[0072] Then, based on the maximum luminous grayscale corresponding to the luminous pixels in the display panel, the number of multiple pixel groups corresponding to the display pixels, the maximum adjusted brightness and the maximum displayable brightness, the brightness range of the display pixels is adjusted from 0 to the maximum displayable brightness to the brightness range from 0 to the maximum adjusted brightness, thereby determining the maximum adjusted display grayscale corresponding to the display pixels.

[0073] For example, the maximum adjusted display grayscale corresponding to the display pixel can be determined by Formula 2, which is as follows:

[0074]

[0075] Among them, m is the maximum adjusted display grayscale corresponding to the display pixel, G is the maximum luminous grayscale corresponding to the luminous pixel, i is the number of multiple pixel groups corresponding to the display pixel, α is the maximum adjusted brightness corresponding to the display pixel, and y is the maximum displayable brightness of the display pixel.

[0076] For each display pixel, a function operation may be performed based on the maximum luminous grayscale, the maximum adjusted display grayscale corresponding to the display pixel, and the display grayscale, and the obtained operation result is used as the mapping value corresponding to the display pixel.

[0077] The function calculation process can refer to Formula 3, which is as follows:

[0078]

[0079] Among them, β is the mapping value corresponding to the display pixel, k y is the display grayscale of the display pixel, m is the maximum adjusted display grayscale corresponding to the display pixel, and G is the maximum luminous grayscale corresponding to the luminous pixel.

[0080] For each display pixel, a function operation is performed according to the maximum luminous grayscale and the mapping value corresponding to the display pixel to obtain the first luminous grayscale of each luminous pixel in each pixel group corresponding to the display pixel in its respective frame display period.

[0081] As an embodiment, performing a function operation based on the maximum luminous grayscale and the mapping value corresponding to the display pixel to obtain the first luminous grayscale of each luminous pixel in each pixel group corresponding to the display pixel within the respective frame display period may also include: determining the value interval of each pixel group corresponding to the display pixel based on the maximum luminous grayscale; for each pixel group corresponding to the display pixel, determining the target value interval of the mapping value corresponding to the display pixel within the value interval of the pixel group; for each pixel group corresponding to the display pixel, obtaining a first sub-mapping function corresponding to the target value interval of the pixel group from the first mapping function corresponding to the pixel group; the first mapping function corresponding to the pixel group includes sub-mapping functions corresponding to multiple value intervals; and determining the first luminous grayscale of each luminous pixel in each pixel group corresponding to the display pixel within the respective frame display period based on the first sub-mapping function of each pixel group corresponding to the display pixel.

[0082] For the n luminous pixels corresponding to the display pixel, the n luminous pixels are divided into j pixel groups. Taking the pixel group as a unit, the grayscale of the luminous pixels in the pixel group can be considered to be consistent. The grayscales of the pixel groups composed of the luminous pixels from the middle to the left and right ends in the pixel sequence corresponding to the display pixel are recorded as w1, w2, w3...w j At this time, the grayscale adjustable range of the display pixel is 0-(j·G).

[0083] Taking into account that when there are bad pixels, the bad pixels have very low brightness or even no brightness, in order to ensure the display quality of low and medium grayscales, the pixel group composed of the luminous pixels at the left and right ends of the pixel sequence corresponding to the display pixel is used as the highest grayscale. The pixel group closer to the middle in the pixel sequence corresponding to the display pixel is responsible for the lower grayscale, and each pixel group is responsible for G-level grayscale modulation.

[0084] For a display pixel, when y>α, its brightness is adjusted from (0-y) to (0-α) according to Formula 2 to obtain the maximum adjusted display grayscale m corresponding to the display pixel. At this time, the grayscale modulation range of the display pixel is 0-m.

[0085] For any pixel group w i , when i is not 1 and j, determine w i The corresponding value intervals are [0, (i-1)·G], ((i-1)·G, i·G] and (i·G, +∞]. In addition, the value intervals of w1 are [0,G] and (G, +∞], w j The value range of is [0, (i―1)·G] and (i·G, +∞].

[0086] For each pixel group corresponding to a display pixel, the target value interval of the pixel group refers to the value interval of the mapping value corresponding to the display pixel. i , the mapping value corresponding to the displayed pixel is within ((i―1)·G, i·G], then the pixel group w i The target value interval is ((i―1)·G, i·G].

[0087] For each pixel group of display pixels, a first mapping function is corresponding to each pixel group, and the first mapping function of each pixel group includes a plurality of sub-mapping functions corresponding to value intervals. j For example, w1, w2, w3…w j The correspondence between each sub-mapping function and the value interval in the first mapping function is as follows:

[0088]

[0089]

[0090] ...

[0092] ...

[0094]

[0095] Among them, it is obvious that the pixel groups w1 and w j The corresponding value intervals include two, pixel groups w1 and w j The corresponding first mapping functions all include sub-mapping functions for the two value intervals, the other pixel groups all correspond to three value intervals, and the first mapping functions corresponding to the other pixel groups all include sub-mapping functions for the three value intervals.

[0096] For each pixel group corresponding to the display pixel, a first sub-mapping function corresponding to the target value interval of the pixel group is obtained from the first mapping function corresponding to the pixel group, and the first luminous grayscale of each luminous pixel in each pixel group corresponding to the display pixel within its respective frame display period is determined directly through the first sub-mapping function of each pixel group.

[0097] For example, the pixel groups corresponding to the display pixels include two pixels w1, w2, and w3. For pixel group w1, the target value interval is determined to be β>G, and the first sub-mapping function corresponding to pixel group w1 is determined to be w1=G. Based on the determined first sub-mapping function, the first emission grayscale of each luminous pixel in pixel group w1 during its respective frame display period is determined to be G. For pixel group w2, the target value interval is determined to be G<β≤2·G, and the first sub-mapping function corresponding to pixel group w2 is determined to be w2=β-G. Based on the determined first sub-mapping function, the first emission grayscale of each luminous pixel in pixel group w2 during its respective frame display period is determined to be β-G. For pixel group w3, the target value interval is determined to be β>2G, and the first sub-mapping function corresponding to pixel group w3 is determined to be w3=G. Based on the determined first sub-mapping function, the first emission grayscale of each luminous pixel in pixel group w3 during its respective frame display period is determined to be G.

[0098] It should be noted that since it is impossible to brighten dark spots in the display panel, the display method of this embodiment (also known as the Demura algorithm) is based on reducing the brightness of the brighter parts of the display panel. Therefore, by using the maximum adjusted brightness as the threshold for determination, the brightness of display pixels brighter than the maximum adjusted brightness is reduced, while pixels darker than the maximum adjusted brightness remain unchanged.

[0099] After obtaining the first emission grayscale of each luminescent pixel during each frame display period, for all luminescent pixels in the display panel, the first emission grayscales corresponding to the same frame display period are aggregated into a single image, serving as a sub-compensation image, to obtain a sub-compensation image corresponding to each frame display period. In other words, each frame display period corresponds to a sub-compensation image. In other words, the grayscale value of a pixel in the sub-compensation image is the first emission grayscale of the luminescent pixel corresponding to that pixel during the frame display period corresponding to that sub-compensation image.

[0100] For example, the frame display period includes 2, and the luminous pixels include 40×40. At this time, for each frame display period, the 40×40 first grayscale value corresponding to the 40×40 luminous pixels in the frame display period is obtained, and a 40×40 image is constructed according to the 40×40 first grayscale value as a sub-compensation image to obtain two sub-compensation images.

[0101] After obtaining multiple sub-compensation images, the multiple sub-compensation images can be stitched together into one compensation image. For example, the multiple sub-compensation images can be stitched together into one image in a left-to-right order (the heights of two adjacent sub-compensation images overlap). For another example, the multiple sub-compensation images can be stitched together into one image in a top-to-bottom order (the widths of two adjacent sub-compensation images overlap).

[0102] In other embodiments, the method for obtaining a compensated image includes: generating multiple initial luminous grayscales corresponding to the display pixels based on the grayscale of the display pixels; determining the first luminous grayscale of each luminous pixel corresponding to the display pixel within the respective frame display period from the multiple initial luminous grayscales corresponding to the display pixels based on the respective luminous pixel serial number attributes of the multiple luminous pixels corresponding to the display pixels; constructing an image based on the first luminous grayscale corresponding to the same frame display period in the first luminous grayscale corresponding to each luminous pixel to obtain a sub-compensated image corresponding to each frame display period; and splicing the multiple sub-compensated images to obtain a compensated image.

[0103] For each display pixel, multiple luminous gray levels corresponding to the display pixel are determined based on the display gray level corresponding to the display pixel. The number of luminous gray levels corresponding to each display pixel does not exceed the number of luminous pixels corresponding to the display pixel. That is, among the multiple luminous pixels corresponding to each display pixel, multiple luminous pixels may share a common luminous gray level.

[0104] In this embodiment, multiple luminous grayscales corresponding to the display pixel can be generated based on the display grayscale of the display pixel and the maximum displayable grayscales of the multiple luminous pixels corresponding to the display pixel. The maximum displayable grayscales of different luminous pixels in the display panel can be the same. The maximum displayable grayscale of a luminous pixel can refer to the grayscale when the luminous pixel in the display panel displays the maximum brightness value. The maximum displayable grayscales of different luminous pixels can be the same. For example, when the grayscale is represented by 0-255, the maximum displayable grayscale of all luminous pixels in the display panel can be 255.

[0105] Specifically, generating multiple initial luminous grayscales corresponding to the display pixel based on the display grayscale of the display pixel and the maximum displayable grayscale of multiple luminous pixels corresponding to the display pixel may include: obtaining the actual display brightness of the display pixel based on the display grayscale of the display pixel; and determining the multiple initial luminous grayscales corresponding to the display pixel based on the actual display brightness of the display pixel, the maximum displayable grayscale of each of the multiple luminous pixels corresponding to the display pixel, and the actual maximum brightness.

[0106] The actual display brightness of a display pixel refers to the brightness value of the display pixel when the display pixel displays the corresponding display grayscale in the image to be displayed, and can be directly determined from the image to be displayed. The actual maximum brightness of a luminous pixel refers to the actual brightness of the luminous pixel when the luminous pixel emits light at the maximum displayable grayscale. The actual maximum brightness of different luminous pixels may be different. Each luminous pixel in the display panel can be controlled to emit light at the maximum displayable grayscale, and then the actual maximum brightness of each luminous pixel can be determined based on the luminous effect of each luminous pixel.

[0107] After determining the actual display brightness of each display pixel based on the image to be displayed, for each display pixel, the actual display brightness of the display pixel, the maximum displayable grayscale of the luminous pixel, and the actual maximum brightness of the luminous pixel corresponding to the display pixel can be comprehensively considered to determine multiple initial luminous grayscales corresponding to the display pixel. All display pixels are traversed to obtain multiple initial luminous grayscales for all display pixels.

[0108] Optionally, the multiple initial luminous grayscales corresponding to the display pixel include a first initial luminous grayscale and a second initial luminous grayscale; the multiple initial luminous grayscales corresponding to the display pixel are determined according to the actual display brightness of the display pixel, the maximum actual display brightness of the multiple luminous pixels corresponding to the display pixel, and the actual maximum brightness, including: dividing the multiple luminous pixels corresponding to the display pixel into a first luminous pixel group and a second luminous pixel group, the luminous pixel serial number attribute of each luminous pixel in the first luminous pixel group is an odd number, and the luminous pixel serial number attribute of each luminous pixel in the second luminous pixel group is an even number; determining the brightness sum value of the first luminous pixel group according to the sum of the actual maximum brightness of all the luminous pixels in the first luminous pixel group; if the brightness sum value of the first luminous pixel group is not less than the actual display brightness corresponding to the display pixel, obtaining the maximum actual display brightness corresponding to the luminous pixel in the first luminous pixel group as the first initial luminous grayscale corresponding to the display pixel; or, if the brightness sum value of the first luminous pixel group is less than the actual display brightness corresponding to the display pixel, calculating the first product The ratio of the first product to the first sum is used as the first initial luminous grayscale corresponding to the display pixel; the first product is the product of the total number of luminous pixels corresponding to the display pixel, the actual display brightness corresponding to the display pixel, and the maximum actual display brightness corresponding to the luminous pixels in the first luminous pixel group, and the first sum is the sum of the actual maximum brightness of all luminous pixels in the first luminous pixel group; if the brightness sum of the first luminous pixel group is not less than the actual display brightness corresponding to the display pixel, a preset grayscale value is obtained as the second initial luminous grayscale corresponding to the display pixel; or if the brightness sum of the first luminous pixel group is less than the actual display brightness corresponding to the display pixel, the ratio of the second product to the second sum is calculated as the second initial luminous grayscale corresponding to the display pixel; the second product is the product of the difference value and the maximum actual display brightness corresponding to the luminous pixels in the second luminous pixel group; the difference is the product of the number of luminous pixels corresponding to the display pixel and the actual display brightness corresponding to the display pixel, and the difference between the first sum; the second sum is the sum of the actual maximum brightness of all luminous pixels in the second luminous pixel group. Wherein, the preset grayscale value can be zero.

[0109] Exemplarily, when each display pixel corresponds to four light-emitting pixels, the process of determining the first initial light-emitting grayscale and the second initial light-emitting grayscale corresponding to the display pixel refers to Formula 4, which is as follows:

[0110]

[0111]

[0112] Wherein, g1 is the first initial luminous grayscale, g2 is the second initial luminous grayscale, y is the actual display brightness corresponding to the display pixel, G is the maximum actual display brightness corresponding to the luminous pixel, x1, x2, x3 and x4 are the actual maximum brightness of the luminous pixels corresponding to the display pixels, wherein the subscripts 1-4 are the luminous pixel serial numbers of the luminous pixels respectively; the sum of the actual maximum brightness of all the luminous pixels in the first luminous pixel group is x1+x3 (that is, the first sum value), and the brightness sum value of the first luminous pixel group is The brightness sum value of the first luminous pixel group is actually the ratio of the sum of the actual maximum brightness of all the luminous pixels in the first luminous pixel group to the number of luminous pixels corresponding to the display pixel, 4yG is the first product, (4y―x1―x3) is the difference, (4y―x1―x3)G is the second product, and x2+x4 is the second sum value.

[0113] After obtaining multiple initial luminous gray levels corresponding to the display pixels, the first luminous gray level of each luminous pixel corresponding to the display pixel within its respective frame display period can be determined from the multiple initial luminous gray levels corresponding to the display pixels according to the respective luminous pixel sequence number attributes of the multiple luminous pixels corresponding to the display pixels.

[0114] Optionally, the multiple initial luminous grayscales include respective initial luminous grayscales of different luminous pixel serial number attributes; according to the respective luminous pixel serial number attributes of the multiple luminous pixels corresponding to the display pixel, determining the first luminous grayscale of each luminous pixel corresponding to the display pixel within the respective frame display period from the multiple initial luminous grayscales corresponding to the display pixel, including: determining the luminous pixel serial number attribute of the zth luminous pixel corresponding to the display pixel; z∈[1,N], N is the total number of luminous pixels corresponding to the display pixel; determining the initial luminous grayscale corresponding to the luminous pixel serial number attribute of the zth luminous pixel from the multiple initial luminous grayscales corresponding to the display pixel as the first luminous grayscale of the zth luminous pixel corresponding to the display pixel within the corresponding zth frame display period; adding 1 to z cumulatively, and returning to the step of determining the luminous pixel serial number attribute of the zth luminous pixel corresponding to the display pixel, until z exceeds N and the acquisition of the first luminous grayscales of the multiple luminous pixels corresponding to the display pixel is terminated.

[0115] As described above, the multiple initial emission grayscales corresponding to the display pixels include a first initial emission grayscale and a second initial emission grayscale; and the emission pixel serial number attribute includes an odd number and an even number. If the emission pixel serial number attribute is an odd number, the first emission grayscale of the zth emission pixel corresponding to the display pixel in the corresponding zth frame display period is determined to be the first initial emission grayscale; if the emission pixel serial number attribute is an even number, the first emission grayscale of the zth emission pixel corresponding to the display pixel in the corresponding zth frame display period is determined to be the second initial emission grayscale.

[0116] It can be seen that among the multiple luminous pixels corresponding to the display pixel, the luminous pixels with odd luminous pixel serial number attributes output the first initial luminous grayscale within their respective frame display periods, and the luminous pixels with even luminous pixel serial number attributes output the second initial luminous grayscale within their respective frame display periods.

[0117] After obtaining the first grayscale of each luminous pixel in each frame display period, the compensation image is constructed in the above manner. After obtaining the compensation image, the SOC can send the sub-compensation image to the FPGA, and the FPGA executes steps S110-S140.

[0118] S120 , splitting the compensation image to obtain multiple sub-compensation images.

[0119] The compensation image is cut in the same manner as above to obtain the sub-compensation images by splicing, and the compensation image is divided into the original multiple sub-compensation images. One frame display period corresponds to one sub-compensation image.

[0120] S130 , acquiring a first luminous grayscale of each luminous pixel in each frame display period from a plurality of sub-compensated images.

[0121] For each sub-compensation image, the first luminous grayscale of each luminous pixel is obtained from the sub-compensation image as the first luminous grayscale of each luminous pixel in the frame display period corresponding to the sub-compensation image, and all sub-compensation images are traversed to obtain the first luminous grayscale of each luminous pixel in each frame display period.

[0122] For example, if there are four frame display periods and four sub-compensation images, and the number of pixels is 40×40, each sub-compensation image includes 40×40 first grayscales. For the first frame display period, the first grayscales of each of the 40×40 pixels are obtained from the sub-compensation image corresponding to the first frame display period, and are used as the first grayscales of the 40×40 pixels in the first frame display period. By traversing the four sub-compensation images in this manner, the first grayscales of the 40×40 pixels in the four frame display periods are obtained (each pixel corresponds to four first grayscales).

[0123] S140. Control the multiple luminous pixels corresponding to each display pixel to emit light according to their respective first luminous grayscales during their respective frame display periods, and control the pixel shift device to move according to a compensation movement mode, so that the light emitted by each luminous pixel during its respective corresponding frame display period can be incident on the corresponding display pixel position.

[0124] Different display modes result in different displacement modes for the pixel shift device. When the display mode is compensation mode, the pixel shift device moves in accordance with the compensation displacement mode, causing light emitted by different luminescent pixels corresponding to the display pixel during the corresponding frame display period to be incident on the display pixel position. It is understood that when one display pixel corresponds to n luminescent pixels, each luminescent pixel also corresponds to n display pixels. The same luminescent pixel provides brightness for n different display pixels during different frame display periods, and different luminescent pixels can provide brightness for the same display pixel during different frame display periods (n luminescent pixels provide brightness for one display pixel).

[0125] For example, the luminous pixels corresponding to the display pixel x1 include s1 and s2. At this time, the frame display period includes two. In the first frame display period, the luminous pixel s1 is incident on the position of the display pixel x1, and the luminous pixel s2 is incident on the display pixel position x3. In the second frame display period, the luminous pixel s2 is incident on the position of the display pixel x1, and the luminous pixel s1 is incident on the display pixel position x4.

[0126] While controlling the multiple luminous pixels corresponding to each display pixel to emit light according to their respective first luminous grayscales within their respective frame display periods, the pixel offset device of the display panel is also controlled to move according to a compensation movement mode, so that the light emitted by each luminous pixel within its respective corresponding frame display period can be incident on the corresponding display pixel position, and the image to be displayed on the display panel has better uniformity.

[0127] In this embodiment, the display device may include a System on Chip (SOC) and a Field Programmable Gate Array (FPGA). The SOC has higher computing power than the FPGA, and steps S110-S130 of this embodiment can be performed by the FPGA, with the SOC generating a compensated image based on the image to be displayed. In this case, when the FPGA controls the display panel to display the compensated image, the FPGA does not need to process the image to be displayed in real time to generate the compensated image. Instead, the SOC generates the compensated image. The higher computing power of the SOC shortens the time required to acquire the compensated image, avoiding the long step-size image acquisition time caused by the FPGA generating the compensated image, thereby improving display efficiency.

[0128] In this embodiment, the first emission grayscales of the plurality of luminescent pixels corresponding to the display pixels in the sub-compensated image are determined based on the respective display grayscales of each display pixel in the image to be displayed. The compensated image is split to obtain sub-compensated images, and the first emission grayscales of the plurality of luminescent pixels are obtained from the sub-compensated images. Then, the plurality of luminescent pixels corresponding to each display pixel are controlled to emit light according to their respective first emission grayscales within their respective frame display periods, and the pixel shifting device is controlled to move according to a compensation movement mode so that light emitted by each luminescent pixel within its respective frame display period can be incident on the corresponding display pixel position. With the aid of the pixel shifting device, the display effect displayed by the luminescent pixels within their respective frame display periods is consistent with the display effect of the image to be displayed, thereby avoiding the situation where poor display uniformity occurs when only the image to be displayed is displayed when the uniformity of the display panel itself is poor, thereby improving the uniformity of the picture displayed by the display panel and enhancing the display effect of the display panel.

[0129] At the same time, the compensation image is directly received and does not need to be generated in real time according to the image to be displayed, which greatly reduces the time consumption of real-time processing of the sub-compensation image and improves display efficiency.

[0130] Reference Figure 7 , Figure 7 A flow chart of a display method proposed in another embodiment of the present application is shown. The method is used for a display device and includes:

[0131] S210 : When the display mode is the super-resolution mode, receiving a super-resolution image corresponding to the image to be displayed.

[0132] Among them, the super-resolution image is obtained by super-resolution processing of the image to be displayed; in the super-resolution mode, each luminous pixel corresponds to multiple super-resolution pixels in the super-resolution image, and one super-resolution pixel corresponding to the luminous pixel corresponds to one frame display period; the luminous pixel provides brightness for the corresponding different super-resolution pixels in different frame display periods.

[0133] In super-resolution mode, when the physical resolution of the display panel is m*n (including m*n luminescent pixels), the movement of the pixel shift device can make the light emitted by a luminescent pixel in different frame display periods incident on different super-resolution pixel positions in the super-resolution image to provide brightness for the corresponding super-resolution pixel. Among them, one pixel in the super-resolution image serves as a super-resolution pixel. Although the number of super-resolution pixels displayed at the same time is the same as the number of luminescent pixels, by utilizing the phenomenon of visual persistence, the super-resolution pixels displayed in different frame display periods are superimposed, thereby achieving a super-resolution effect.

[0134] For example, if the display panel wants to achieve 4 times super-resolution display, when the physical resolution of the display panel is m*n, the super-resolution image can be a 2m*2n image (including 2m*2n super-resolution pixels). At this time, the corresponding frame display period is 4, and in each frame display period, one luminous pixel provides brightness for one super-resolution pixel.

[0135] Super-resolution images can be generated through deep learning, interpolation, and edge methods. Interpolation is one of the simplest super-resolution signal processing methods. This method increases the image resolution by inserting new pixel values between pixels in a low-resolution image. Common interpolation methods include bilinear interpolation and cubic spline interpolation. Edge methods improve image resolution by detecting and enhancing edge information within the image. This method leverages the importance of edges in an image, enhancing edge details to create a clearer image. Deep learning methods achieve superior super-resolution by building a deep neural network model and leveraging a large amount of training data for learning and optimization.

[0136] S220 , de-framing the super-resolution image to obtain multiple sub-super-resolution images.

[0137] Each sub-super-resolution image includes the second luminous grayscale of each luminous pixel in the display panel.

[0138] The super-resolution image can be deframed to obtain multiple sub-super-resolution images, and the size of each sub-super-resolution image is the same as the size of the display panel, that is, the number of pixels in the sub-super-resolution image is the same as the number of luminous pixels in the display panel, and each pixel in the sub-super-resolution image corresponds one-to-one to the luminous pixel in the display panel.

[0139] Since the sub-super-resolution image is obtained by deframing the super-resolution image, the sub-super-resolution image includes some super-resolution pixels in the super-resolution image, and the pixels in the sub-super-resolution image are also super-resolution pixels. The grayscale of each super-resolution pixel in the sub-super-resolution image can be used as the second luminous grayscale of the luminous pixel corresponding to the super-resolution pixel.

[0140] Among them, the frame splitting method is not limited in this application. For example, a 2m*2n super-resolution image can be divided into 2*2 pixel blocks, and each pixel block takes a super-resolution pixel to construct an image m*n, obtaining 4 m*n sub-super-resolution images. For another example, a 2m*2n super-resolution image can be divided into 4 m*n image blocks, and one image block is used as a sub-super-resolution image.

[0141] like Figure 8-9 As shown, Figure 8 After the 2m*2n super-resolution image in is deframed, we get Figure 9 The four m*n sub-super-resolution images shown in a, b, c and d.

[0142] S230 , acquiring a second luminous grayscale of each luminous pixel within each frame display period from the plurality of sub-super-resolution images.

[0143] For each sub-super-resolution image, the second luminous grayscale of each luminous pixel is obtained from the sub-super-resolution image as the second luminous grayscale of each luminous pixel in the frame display period corresponding to the sub-super-resolution image. All sub-super-resolution images are traversed to obtain the second luminous grayscale of each luminous pixel in each frame display period.

[0144] For example, if there are four frame display periods and four sub-super-resolution images, each with 40×40 luminous pixels, each sub-super-resolution image includes 40×40 second luminous grayscales. For the first frame display period, the second luminous grayscale of each of the 40×40 luminous pixels in the sub-super-resolution image corresponding to the first frame display period is obtained as the first luminous grayscale of the 40×40 luminous pixels in the first frame display period. This process is repeated through the four sub-super-resolution images to obtain the second luminous grayscales of the 40×40 luminous pixels in the four frame display periods (each luminous pixel corresponds to four second luminous grayscales).

[0145] S240: Control the plurality of luminescent pixels corresponding to each display pixel to emit light according to their respective second luminescent grayscales during their respective frame display periods, and control the pixel shift device to move according to the super-resolution shift mode, so that light emitted by each luminescent pixel during its respective corresponding frame display period can be incident on the corresponding super-resolution pixel position.

[0146] Different display modes require different displacement methods for the pixel shifting device. When the display mode is super-resolution, the pixel shifting device moves in a super-resolution shifting mode, directing light emitted by the luminous pixel during different frame display periods to different super-resolution pixel locations. It should be understood that when one luminous pixel corresponds to n super-resolution pixels, each luminous pixel provides brightness for n different super-resolution pixels.

[0147] For example, the super-resolution pixels corresponding to the luminous pixel g1 include cf1, cf2, cf3 and cf4. At this time, the frame display period includes 4. In the first frame display period, the luminous pixel g1 is incident on the position of cf1, in the second frame display period, the luminous pixel g1 is incident on the position of cf2, in the third frame display period, the luminous pixel g1 is incident on the position of cf4, and in the fourth frame display period, the luminous pixel g1 is incident on the position of cf4.

[0148] While controlling the multiple luminous pixels corresponding to each display pixel to emit light according to their respective second luminous grayscales during their respective frame display periods, the pixel offset device of the display panel is also controlled to move according to a compensation movement mode, so that the light emitted by each luminous pixel during its respective frame display period can be incident on the corresponding super-resolution pixel position, and the clarity of the image to be displayed on the display panel is higher.

[0149] like Figure 10 As shown, super-resolution images F22 and F32 are generated based on the image to be displayed, and the super-resolution images F22 and F32 are deframed to obtain F1, F2, F3, and F4 corresponding to F22, and F5, F6, F7, and F8 corresponding to F32. When the display panel operates at a refresh rate of 120 Hz, by displaying images F1, F2, F3, and F4 of 640×480 size during one frame duration (one frame display duration at a refresh rate of 30 Hz), images F1, F2, F3, and F4 are superimposed, resulting in a display effect equivalent to displaying F22 of 1280×960 size at 30 Hz (generally speaking, when displaying F22 at 30 Hz, it does not start from one frame duration, and the display duration of F22 generally does not reach one frame duration, and the interval between the start times of two adjacent frames is usually 1 / 30 second). It can be seen that the method of this embodiment achieves higher clarity by sacrificing the refresh rate of the picture.

[0150] In this embodiment, a luminous pixel provides brightness for different super-resolution pixels corresponding to it in a super-resolution image during different frame display periods, and the super-resolution image is deframed to obtain multiple sub-super-resolution images. The second luminous grayscale of each luminous pixel during each frame display period is obtained from the multiple sub-super-resolution images. Then, the multiple luminous pixels corresponding to each display pixel are controlled to emit light according to their respective second luminous grayscales during their respective frame display periods, and the pixel shift device is controlled to move according to a super-resolution shift mode so that the light emitted by each luminous pixel during its respective frame display period can be incident on the corresponding super-resolution pixel position. With the help of the pixel shift device, the display effects displayed by the luminous pixels during their respective frame display periods are superimposed, thereby achieving super-resolution display, thereby improving the image clarity displayed by the display panel.

[0151] At the same time, the super-resolution image is received directly, and there is no need to generate the super-resolution image in real time according to the image to be displayed, which greatly reduces the time consumption of real-time processing of the sub-super-resolution image and improves the display efficiency.

[0152] Reference Figure 11 , Figure 11 A flow chart of a display method proposed in another embodiment of the present application is shown. The method is used for a display device and includes:

[0153] S310 : When the display mode is the super-resolution compensation mode, receiving a target super-resolution compensated image corresponding to the image to be displayed.

[0154] The method for acquiring a target super-resolution compensated image includes: receiving a super-resolution image or performing super-resolution processing on an image to be displayed to obtain a super-resolution image; deframing the super-resolution image into multiple sub-super-resolution images, each sub-super-resolution image including a second luminous grayscale corresponding to each luminous pixel; determining multiple sub-super-resolution compensated images corresponding to the sub-super-resolution image based on the second luminous grayscale corresponding to each luminous pixel in the sub-super-resolution image, wherein one sub-super-resolution compensated image corresponds to one frame display period, and the sub-super-resolution compensated image includes a third luminous grayscale of each luminous pixel within the frame display period corresponding to the sub-super-resolution compensated image; selecting one sub-super-resolution compensated image from the multiple sub-super-resolution compensated images corresponding to each sub-super-resolution compensated image and fusing them into one image to obtain multiple super-resolution compensated images corresponding to the super-resolution image; and splicing the multiple super-resolution compensated images to obtain a target super-resolution compensated image; wherein, in a super-resolution compensation mode, a luminous pixel provides brightness for multiple super-resolution compensated pixels in one super-resolution compensated image, and super-resolution compensated pixels corresponding to positions in different super-resolution compensated images provide brightness through different luminous pixels.

[0155] The method for acquiring a super-resolution image and deframing the super-resolution image into multiple sub-super-resolution images is as described above and will not be repeated here. As can be seen from the above, the sub-super-resolution images are the same size as the display panel, that is, the grayscale of each super-resolution pixel in the sub-super-resolution image is the second luminous grayscale of the luminous pixel.

[0156] It is understood that in some embodiments, an electronic device can directly receive a super-resolution image sent by another device, and thus the electronic device can directly use the super-resolution image to determine the target super-resolution compensated image. In other words, the electronic device no longer needs to perform super-resolution processing based on the image to be displayed to obtain the super-resolution image.

[0157] Each sub-super-resolution image can be used as an image to be displayed. In accordance with the method for determining the sub-compensated image corresponding to the image to be displayed in S110, multiple compensated images corresponding to the sub-super-resolution image can be determined as multiple sub-super-resolution compensated images corresponding to the sub-super-resolution image. The number of the multiple sub-super-resolution compensated images corresponding to a sub-super-resolution image is the same as the number of luminous pixels providing brightness for a super-resolution pixel position.

[0158] For example, two luminous pixels are used to provide brightness for a super-resolution pixel position. In this case, the number of the multiple sub-super-resolution compensation images corresponding to one sub-super-resolution image is also two.

[0159] Then, one sub-super-resolution compensation image is selected from each of the multiple sub-super-resolution compensation images corresponding to each sub-super-resolution image and fused into one image (the fusion method corresponds to the aforementioned method of deframing according to the super-resolution image) to obtain a super-resolution compensation image, and all the multiple sub-super-resolution compensation images are traversed to obtain multiple super-resolution compensation images corresponding to the super-resolution image (the size of the super-resolution compensation image is the same as the size of the super-resolution image); then, the multiple super-resolution compensation images corresponding to the super-resolution image are spliced into a target super-resolution compensation image (wherein, the splicing method refers to the method of splicing sub-compensation images above, which will not be repeated here).

[0160] For example, if the resolution of a super-resolution image is 2m*2n, it corresponds to four sub-super-resolution images. Each sub-super-resolution image corresponds to two sub-super-resolution compensation images. From the two sub-super-resolution compensation images corresponding to each sub-super-resolution image, one image is selected and stitched together to form a super-resolution compensation image (the result of stitching the four selected sub-super-resolution compensation images). The two sub-super-resolution compensation images corresponding to each sub-super-resolution image are then traversed to obtain two super-resolution compensation images. The two super-resolution compensation images are then stitched together to form a target super-resolution compensation image. The size of the target super-resolution compensation image can be 4m*2n or 2m*4n, etc.

[0161] For each super-resolution compensated image, one luminous pixel corresponds to multiple super-resolution compensated pixels (one pixel in the super-resolution compensated image serves as a super-resolution compensated pixel). For example, the resolution of the display panel is m*n, the super-resolution image is 2m*2n, and the size of a super-resolution compensated image is also 2m*2n. At this time, one luminous pixel corresponds to 4 super-resolution compensated pixels in the super-resolution compensated image.

[0162] Based on the principles of S110-S140, for each super-resolution pixel in the super-resolution image, the actual display effect of the super-resolution pixel is the effect of the multiple luminescent pixels corresponding to the super-resolution pixel, and the multiple luminescent pixels corresponding to the super-resolution pixel emit light according to the grayscale of the super-resolution compensation pixel corresponding to the super-resolution pixel (i.e., the third grayscale of the luminescent pixel). In other words, for each super-resolution pixel, the super-resolution pixel corresponds to a super-resolution compensation pixel in each super-resolution compensation image, and the multiple super-resolution compensation pixels corresponding to the super-resolution pixel in the multiple super-resolution compensation images (i.e., the multiple super-resolution compensation pixels in the multiple super-resolution compensation images that correspond to the super-resolution pixel, where corresponding position may mean that the pixel coordinates are the same) provide brightness through different luminescent pixels.

[0163] For example, if a super-resolution image is 2m*2n, it corresponds to two 2m*2n super-resolution compensation images. The super-resolution pixel with coordinates (m, n) in the super-resolution compensation image corresponds to the super-resolution compensation pixel with coordinates (m, n) in each super-resolution compensation image. In this case, the super-resolution pixel with coordinates (m, n) corresponds to two super-resolution compensation pixels with coordinates (m, n). The two super-resolution compensation pixels with coordinates (m, n) provide brightness through different luminous pixels, so that the display effect of the super-resolution compensation pixel with coordinates (m, n) matches that of the super-resolution pixel with coordinates (m, n).

[0164] A super-resolution compensated image can be split into p sub-super-resolution compensated images of the same size as the display panel. The number of sub-super-resolution compensated images obtained after q super-resolution compensated images are deframed is p*q, and the luminous pixels of the display panel output a third luminous grayscale each time. At this time, the corresponding number of frame display periods is p*q.

[0165] For example, super-resolution compensation pixels cb11, cb12, cb13, and cb14 in super-resolution compensation image cb1 provide brightness through luminescent pixel g11. Super-resolution compensation pixels cb11, cb12, cb13, and cb14 in super-resolution compensation image cb1 correspond to super-resolution compensation pixels cb21, cb22, cb23, and cb24 in super-resolution compensation image cb2, respectively. Super-resolution compensation pixels cb21, cb22, cb23, and cb24 provide brightness through luminescent pixel g12. In this case, there are eight corresponding frame display periods. Within these eight frame display periods, g11 provides brightness to cb11, cb12, cb13, and cb14, respectively, in four frame display periods, and g12 provides brightness to cb21, cb22, cb23, and cb24, respectively, in the remaining four frame display periods.

[0166] S320 , de-frame the target super-resolution compensated image to obtain a plurality of sub-super-resolution compensated images corresponding to the target super-resolution compensated image.

[0167] The target super-resolution compensated image can be divided according to the method of splicing multiple super-resolution compensated images into a target super-resolution compensated image to obtain multiple super-resolution compensated images, and then each super-resolution compensated image is deframed to obtain multiple sub-super-resolution compensated images.

[0168] S330 , acquiring a third luminous grayscale of each luminous pixel from a plurality of sub-super-resolution compensated images corresponding to the target super-resolution compensated image.

[0169] For each sub-super-resolution compensated image corresponding to the target super-resolution compensated image, the third luminous grayscale of each luminous pixel is obtained from the sub-super-resolution compensated image as the third luminous grayscale of each luminous pixel in the frame display period corresponding to the sub-super-resolution compensated image. All sub-super-resolution compensated images are traversed to obtain the third luminous grayscale of each luminous pixel in each frame display period.

[0170] S340: Control each luminous pixel to emit light within its respective frame display period according to the third luminous grayscale of each luminous pixel, and control the pixel shift device to move in a super-resolution compensation mode so that light emitted by each luminous pixel is incident on a corresponding super-resolution compensation display pixel position.

[0171] Specifically, the pixel shift device is displaced in different ways according to different display modes. When the display mode is the super-resolution compensation mode, when the pixel shift device moves according to the super-resolution movement mode, light emitted by the same luminescent pixel in different frame display periods is incident on different super-resolution compensation pixel positions, and the same super-resolution compensation pixel position receives light emitted by different luminescent pixels in different frame display periods.

[0172] Among them, for each luminous pixel, when the luminous pixel emits light according to the third luminous grayscale within the same super-resolution compensation image, the luminous pixel provides brightness for different super-resolution compensation pixel positions (one luminous pixel provides brightness for L super-resolution compensation pixels, where L is the number of sub-super-resolution compensation images included in the super-resolution compensation image); for each luminous pixel, when the luminous pixel emits light according to the third luminous grayscale belonging to different super-resolution compensation images, the luminous pixel provides brightness for different super-resolution compensation pixel positions (one luminous pixel provides brightness for O super-resolution compensation pixels, where O is the number of super-resolution compensation images). At this time, each luminous pixel provides brightness for L*O super-resolution compensation pixel positions; for each super-resolution compensation pixel position, each luminous pixel corresponding to the super-resolution compensation pixel provides brightness for the super-resolution compensation pixel according to its respective third luminous grayscale (the number of luminous pixels providing brightness for each super-resolution compensation pixel is O).

[0173] For example, a super-resolution image corresponds to two super-resolution compensation images, each super-resolution compensation image is split into four sub-super-resolution compensation images, and the frame display period is 2*4. At this time, the super-resolution compensation pixels corresponding to the luminous pixel g33 include cf31, cf32, cf33, cf34, cf35, cf36, cf37 and cf38, and the super-resolution compensation pixels corresponding to the luminous pixel g44 include cf41, cf42, cf43, cf44, cf31, cf32, cf33 and cf34. Figure 12As shown, in the first four frame display periods, the luminous pixel g33 provides brightness to cf31, cf32, cf33, and cf34 in turn, and the luminous pixel g44 provides brightness to cf41, cf42, cf43, and cf44 in turn. In the last four frame display periods, the luminous pixel g33 provides brightness to cf35, cf36, cf37, and cf38 in turn, and the luminous pixel g44 provides brightness to cf31, cf32, cf33, and cf34 in turn.

[0174] In some embodiments, the method for acquiring the target super-resolution compensated image may further include: acquiring an image to be displayed; determining multiple sub-compensated images corresponding to the image to be displayed based on the display grayscale of each display pixel in the image to be displayed, wherein one sub-compensated image includes the first luminous grayscale corresponding to each luminous pixel in the display panel; performing super-resolution processing on each sub-compensated image to obtain an initial super-resolution compensated image corresponding to each sub-compensated image; an initial super-resolution compensated image corresponds to the fourth luminous grayscale of each luminous pixel in different frame display periods; deframing the initial super-resolution compensated image to obtain multiple initial sub-super-resolution compensated images corresponding to each initial super-resolution compensated image, wherein one initial sub-super-resolution compensated image corresponds to the fourth luminous grayscale of each luminous pixel in one frame display period; selecting one initial sub-super-resolution compensated image from the multiple initial sub-super-resolution compensated images corresponding to each of the initial super-resolution compensated images and fusing them into one image to obtain a fused super-resolution compensated image corresponding to the super-resolution image; and splicing the fused super-resolution compensated images to obtain a target super-resolution compensated image.

[0175] The process of determining the sub-compensated images is described in S110-S140 and will not be repeated here. Subsequently, super-resolution processing is performed on each sub-compensated image to obtain multiple initial super-resolution compensated images. For example, if the display panel, the image to be displayed, and the sub-compensated images are all of size m*n, the initial super-resolution compensated image determined is 2m*2n. In this case, one initial super-resolution compensated image includes four fourth luminous grayscales corresponding to one luminous pixel, with each fourth luminous grayscale corresponding to one frame display period.

[0176] Each initial super-resolution compensated image can then be deframed to obtain initial sub-super-resolution compensated images corresponding to the initial super-resolution compensated image. For example, if the display panel, the image to be displayed, and the sub-compensated image are all of size m*n, and the determined initial super-resolution compensated image is 2m*2n, each initial super-resolution compensated image can be deframed to obtain m*n initial sub-super-resolution compensated images. In this case, one initial super-resolution compensated image can be deframed to obtain four initial sub-super-resolution compensated images.

[0177] The process of determining the fused super-resolution image can refer to the process of determining the super-resolution compensation image described above, and will not be repeated here. Afterwards, the multiple fused super-resolution images are spliced into one image as the target super-resolution compensation image.

[0178] Accordingly, S320 includes: de-framing the target super-resolution compensated image to obtain a plurality of initial sub-super-resolution compensated images corresponding to the target super-resolution compensated image. The target super-resolution compensated image may be divided according to the method for splicing a plurality of fused super-resolution images to obtain a plurality of fused super-resolution images, and then de-framing each fused super-resolution image to obtain a plurality of initial sub-super-resolution compensated images.

[0179] Accordingly, S330 includes: acquiring the fourth luminous grayscale of each luminous pixel from a plurality of initial sub-super-resolution compensation images corresponding to the target super-resolution compensation image.

[0180] For each initial sub-super-resolution compensated image corresponding to the target super-resolution compensated image, the fourth luminous grayscale of each luminous pixel is obtained from the initial sub-super-resolution compensated image as the fourth luminous grayscale of each luminous pixel in the frame display period corresponding to the initial sub-super-resolution compensated image. All initial sub-super-resolution compensated images are traversed to obtain the fourth luminous grayscale of each luminous pixel in each frame display period.

[0181] Accordingly, S340 includes: controlling each luminous pixel to emit light within its respective frame display period according to the fourth luminous grayscale of each luminous pixel, and controlling the pixel shift device to move in a super-resolution compensation mode so that the light emitted by each luminous pixel is incident on the corresponding super-resolution compensation display pixel position.

[0182] In this embodiment, the pixel shift device is used to superimpose the display effects of the luminous pixels within their respective frame display periods, thereby achieving super-resolution compensation display, thereby improving the clarity of the picture displayed by the display panel.

[0183] At the same time, with the help of the pixel offset device, the display effect displayed by the luminous pixels in their respective frame display periods is consistent with the display effect of the super-resolution image, avoiding the situation where only the super-resolution image is displayed when the uniformity of the display panel itself is poor, resulting in poor display uniformity, thereby improving the uniformity of the picture displayed by the display panel and enhancing the display effect of the display panel.

[0184] In addition, the super-resolution compensated image is directly received and does not need to be generated in real time according to the image to be displayed, which greatly reduces the time consumption of real-time processing of the sub-super-resolution compensated image and improves display efficiency.
