[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. According to the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In the following description, the terms "first\second" involved are merely used to distinguish similar objects and do not represent a specific ordering of 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.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0035] Figure 1 A schematic diagram of a picture displayed by a MicroLED display panel in the related art is shown; there are bad pixels in the MicroLED display panel. Due to the presence of bad pixels in the display panel, the bad pixels cannot emit light normally (do not emit light or emit light at low brightness), resulting in uneven brightness in the image output by the display panel, for example, Figure 1 The dark spots and uneven areas in the image are where the bad pixels are located.

[0036] Based on this, the inventor proposed the display method of the present application, in which each display pixel in the image to be displayed corresponds to multiple display pixels in the display panel, and the luminous grayscale values ​​of the multiple display pixels corresponding to each display pixel in their respective luminous time slices are determined, and the luminous grayscale values ​​of the multiple display pixels corresponding to each display pixel in their respective luminous time slices are used to control the luminescence of the multiple luminous pixels corresponding to each display pixel, so that the brightness displayed by each display pixel matches the target display grayscale value required. In the present application, when there are bad pixel pixels among the multiple luminous pixels corresponding to each display pixel, the luminescence can still be performed by the luminous grayscale values ​​of the other luminous pixels corresponding to each display pixel in their respective luminous time slices, thereby avoiding the situation in which the luminous pixel and the display pixel are one-to-one, and the luminous pixel is a bad pixel, resulting in the display pixel corresponding to the luminous pixel being unable to display normally, thereby improving the degree of fit between the actual brightness of the display pixel and the target display grayscale value, and further improving the display effect of the image to be displayed displayed by the display panel.

[0037] Reference Figure 2 , Figure 2A flow chart of a display method proposed in an embodiment of the present application is shown. The method is used for a display device, and the method includes:

[0038] S110, obtaining a target display grayscale value, a maximum adjustment brightness, and a maximum displayable brightness corresponding to each display pixel in the image to be displayed.

[0039] 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.

[0040] 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).

[0041] When the luminous pixels in the display panel emit light, the pixel shift device also shifts, so that the optical path of the luminous pixels changes, so that the light emitted by multiple luminous pixels can be incident on the same display position along the changed optical path. The display position serves as the display pixel corresponding to the multiple luminous pixels, that is, the display effect of any display pixel in the image to be displayed is the effect of the joint action of the multiple luminous pixels corresponding to the display pixel, that is, any display pixel in the image to be displayed provides brightness through the multiple luminous pixels corresponding to the display pixel. Among them, one pixel in the image to be displayed serves as a display pixel. That is, each luminous pixel on the display panel emits light according to the specified grayscale value to display the specified brightness. At the same time, the pixel shift device changes the propagation direction of the optical path of these luminous pixels, and shifts the light emitted by multiple luminous pixels to the same display pixel in a time-sharing manner.

[0042] It is worth mentioning that when the pixel shift device in the present application is shifted, the optical path of the multiple light-emitting pixels corresponding to each display pixel is moved to the position where the display pixel is located. That is to say, the purpose of the pixel shift device shift is to change the optical path of the multiple light-emitting pixels corresponding to each display pixel, so that the light emitted by the multiple light-emitting pixels corresponding to each display pixel can be incident on the same display position along the changed optical path.

[0043] For example, a single display pixel is provided with brightness by four luminous pixels. The luminous pixels on the back panel of the display panel change the direction of the light path through the pixel offset device so that the light path of the same luminous pixel moves to different positions in the image plane. The time of a frame is used as a cycle, and each cycle is divided into luminous time slices corresponding to four luminous pixels. The luminous time slice of a luminous pixel refers to the period of time when the luminous pixel emits light in a frame. That is, at this time, the display duration of a frame is divided into four luminous time slices.

[0044] like Figure 3 As shown, in the first light-emitting time slice, the light paths of the A, B, C, and D light-emitting 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 light-emitting pixels when propagating along a straight line.

[0045] like Figure 4 As shown, in the second light-emitting time slice, the light paths of the A, B, C, and D light-emitting 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 when the A, B, C, and D light-emitting pixels propagate along a straight line.

[0046] like Figure 5 As shown, in the third light-emitting time slice, the light paths of the A, B, C, and D light-emitting 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 light-emitting pixels when propagating along a straight line.

[0047] like Figure 6 As shown, in the fourth light-emitting time slice, the light paths of the A, B, C, and D light-emitting 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 when the A, B, C, and D light-emitting pixels propagate along a straight line.

[0048] It is understandable that when the display panel includes luminous pixels under different color channels and the image to be displayed includes display pixels under different color channels, the multiple luminous pixels corresponding to the display pixels under a single color channel also belong to the luminous pixels under the single color channel. For example, a red display pixel under a color channel corresponds to multiple red luminous pixels under a red channel.

[0049] The target display grayscale value corresponding to the display pixel is the actual grayscale value of the display pixel in the image to be displayed. The grayscale value can be 4 bits, 8 bits, or 16 bits of data. For example, when the grayscale value is 4 bits, the grayscale value includes 15 grayscale values ​​from 0 to 15. The grayscale brightness range that can be displayed by the display pixel can be divided according to the requirements to obtain multiple grayscale ranges, and each grayscale range is indicated by a grayscale value. The content displayed by different display pixels in the image to be displayed may be different, so the target display grayscale values ​​corresponding to different display pixels may be different.

[0050] The maximum adjusted brightness corresponding to the display pixel may be a brightness value set according to demand and not greater than the maximum brightness corresponding to the display pixel, wherein the maximum brightness corresponding to the display pixel may refer to the maximum brightness value of the display pixel under the action of multiple normally luminous pixels. In this embodiment, the brightness value of the display pixel may be indicated by 0-255, that is, the maximum brightness corresponding to the display pixel is 255, at this time, the maximum adjusted brightness corresponding to the display pixel may be a value not greater than 255, such as 160 or 180. The maximum adjusted brightness corresponding to different display pixels may be the same.

[0051] The maximum displayable brightness corresponding to the display pixel may refer to the maximum brightness value that the display pixel can display, wherein the method for obtaining the maximum displayable brightness corresponding to the display pixel may include: when controlling the multiple luminous pixels corresponding to the display pixel to emit light according to the maximum luminous power, obtaining the actual brightness value of each of the multiple luminous pixels corresponding to the display pixel; performing weighted summation on the actual brightness values ​​of each 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.

[0052] It can be understood 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:

[0053]

[0054] 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 iis 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.

[0055] It should be noted that for a normal luminous pixel, when the luminous pixel emits light at the maximum luminous power, the grayscale value of the luminous pixel is the maximum luminous grayscale value (that is, the maximum luminous grayscale value corresponding to each luminous pixel in the display panel of the present application is the same); however, for a bad pixel, when it emits light at the maximum luminous power, the grayscale value of the luminous pixel is lower than the maximum luminous grayscale value, and at the same time, the actual brightness value of the bad pixel is lower than the actual brightness value of the normal luminous pixel. That is, although the bad pixel also emits light at the maximum luminous power, the grayscale value of the luminous pixel is lower than the maximum luminous grayscale value, and the actual brightness value is lower.

[0056] 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.

[0057] S120 , determining the luminous grayscale values ​​of a plurality of luminous pixels corresponding to each display pixel in the display panel within their respective luminous time slices according to the target display grayscale value corresponding to each display pixel, the maximum adjusted brightness, and the maximum displayable brightness.

[0058] For each display pixel, the luminous grayscale values ​​of multiple luminous pixels corresponding to the display pixel can be determined according to the target display grayscale value, the maximum adjustment brightness and the maximum displayable brightness corresponding to the display pixel, and each luminous pixel emits light according to the determined luminous grayscale value in its respective luminous time slice. The luminous grayscale value refers to the grayscale value when the luminous pixel emits light.

[0059] The durations of the light-emitting time slices of the multiple light-emitting pixels corresponding to each display pixel may be the same, and the arrangement order of the light-emitting time slices of the multiple light-emitting pixels corresponding to each display pixel may be arbitrary.

[0060] For each display pixel, the luminous grayscale values ​​of the multiple luminous pixels corresponding to the display pixel in their respective luminous time slices are determined, and the multiple luminous pixels corresponding to the display pixel are controlled to emit light according to the luminous grayscale values ​​of the multiple luminous pixels corresponding to the display pixel in their respective luminous time slices. The display panel can display the image to be displayed, and the actual grayscale value of each display pixel point in the image to be displayed displayed by the display panel has a high degree of fit between the target display grayscale value.

[0061] For example, the display pixel x1 corresponds to four luminous pixels f1, f2, f3 and f4, and the luminous time slices of the four luminous pixels f1, f2, f3 and f4 are t1, t2, t3 and t4 respectively, and the durations of t1, t2, t3 and t4 are the same. According to the target display grayscale value, the maximum adjustment brightness and the maximum displayable brightness corresponding to the display pixel x1, the luminous grayscale values ​​of the four luminous pixels f1, f2, f3 and f4 are determined to be h1, h2, h3 and h4 respectively. At this time, the luminous grayscale value of the luminous pixel f1 in the luminous time slice t1 is h1, the luminous grayscale value of the luminous pixel f2 in the luminous time slice t2 is h2, the luminous grayscale value of the luminous pixel f3 in the luminous time slice t3 is h3, and the luminous grayscale value of the luminous pixel f4 in the luminous time slice t4 is h4. And the order of the luminous time slices is t1-t2-t3-t4.

[0062] S130, controlling the multiple luminous pixels corresponding to each display pixel to emit light according to the luminous grayscale values ​​of the multiple luminous pixels corresponding to each display pixel in their respective luminous time slices; controlling the pixel shift device to move so that the light emitted by the multiple luminous pixels in their respective luminous time slices can be incident on the corresponding display pixel position.

[0063] The pixel offset device of the display panel can be controlled to offset according to the luminous grayscale values ​​of the multiple luminous pixels corresponding to each display pixel in their respective luminous time slices, so that the multiple luminous pixels corresponding to the display pixel emit light according to the luminous grayscale values ​​in their respective luminous time slices, and the light path that emits light according to the luminous grayscale values ​​is moved to the display pixel, so that the display pixel can display the image to be displayed, and the actual grayscale value of each display pixel point in the image to be displayed displayed by the display panel has a high degree of fit with the target display grayscale value.

[0064] It should be noted that when the display panel is a color panel, for each single color channel, the display pixels under the single color channel in the image to be displayed can determine the luminous grayscale values ​​of multiple luminous pixels corresponding to the display pixels under the single color channel in their respective luminous time slices according to the method of the present application.

[0065] For example, the display panel is a color display panel, and the luminous pixels include red luminous pixels under a red channel, green luminous pixels under a green channel, and blue luminous pixels under a blue channel. Accordingly, the image to be displayed also includes red display pixels, green display pixels, and blue display pixels. For the multiple red luminous pixels corresponding to the red display pixels, the luminous grayscale values ​​of the multiple red luminous pixels corresponding to each red display pixel in their respective luminous time slices are determined according to the above method. Similarly, for the multiple green luminous pixels corresponding to the green display pixels, the luminous grayscale values ​​of the multiple green luminous pixels corresponding to each green display pixel in their respective luminous time slices are determined according to the above method. Similarly, for the multiple blue luminous pixels corresponding to the blue display pixels, the luminous grayscale values ​​of the multiple blue luminous pixels corresponding to each blue display pixel in their respective luminous time slices are determined according to the above method.

[0066] As an example, the light emitting principle of a color display panel is as follows Figure 7 As shown, the color display panel includes a red channel sub-light-emitting panel 701, a green channel sub-light-emitting panel 702, a blue channel sub-light-emitting panel 703 and a light-combining element 704. The red channel sub-light-emitting panel 701 includes red light-emitting pixels under the color channel, the green channel sub-light-emitting panel 702 includes green light-emitting pixels under the green channel, and the blue channel sub-light-emitting panel 703 includes blue light-emitting pixels under the blue channel. When the red light-emitting pixels under the color channel in the red channel sub-light-emitting panel 701, the green light-emitting pixels under the green channel in the green channel sub-light-emitting panel 702, and the blue light-emitting pixels under the blue channel in the blue channel sub-light-emitting panel 703 emit light, the light paths of the red light-emitting pixels under the color channel in the red channel sub-light-emitting panel 701, the green light-emitting pixels under the green channel in the green channel sub-light-emitting panel 702, and the blue light-emitting pixels under the blue channel in the blue channel sub-light-emitting panel 703 are combined through the light-combining element 704 to realize the combination of red light, green light and blue light to obtain colored light, so that the color display panel can output a colored image to be displayed.

[0067] In this embodiment, each display pixel in the image to be displayed corresponds to multiple display pixels in the display panel, and the luminous grayscale values ​​of the multiple display pixels corresponding to each display pixel in their respective luminous time slices are determined, and the luminous grayscale values ​​of the multiple display pixels corresponding to each display pixel in their respective luminous time slices are used to control the luminescence of the multiple luminous pixels corresponding to each display pixel, so that the brightness displayed by each display pixel matches the target display grayscale value required. When there are bad pixel pixels in the multiple luminous pixels corresponding to each display pixel, the luminous grayscale values ​​of the other luminous pixels corresponding to each display pixel in their respective luminous time slices can still be used to emit light, thereby avoiding the situation where the luminous pixel and the display pixel are one-to-one, and the luminous pixel is a bad pixel, resulting in the display pixel corresponding to the luminous pixel being unable to display normally, thereby improving the degree of fit between the actual brightness of the display pixel and the target display grayscale value, and further improving the display effect of the image to be displayed displayed by the display panel.

[0068] At the same time, in the present application, multiple luminous pixels hit the same display pixel. Compared with the solution in which one display pixel corresponds to four non-moving pixels, the uniformity is better, and multiple display pixels can reuse the same luminous pixel, which can achieve a uniform display effect with fewer luminous pixels.

[0069] Reference Figure 8 , Figure 8 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 the method includes:

[0070] S210, obtaining a target display grayscale value, a maximum adjustment brightness, and a maximum displayable brightness corresponding to each display pixel in the image to be displayed.

[0071] The description of S210 refers to the description of S110 above, and will not be repeated here.

[0072] S220 , if the maximum displayable brightness corresponding to the display pixel is less than or equal to the maximum adjusted brightness, obtain the target display grayscale value corresponding to the display pixel as the luminous grayscale value of the plurality of luminous pixels corresponding to the display pixel in their respective luminous time slices.

[0073] For any display pixel, if the maximum displayable brightness corresponding to the display pixel is less than or equal to the maximum adjusted brightness of the display pixel, the target display grayscale value corresponding to the display pixel is directly used as the luminous grayscale value of the multiple luminous pixels corresponding to the display pixel in their respective luminous time slices. At this time, there exists k1=k2=k3=...=k n =k y , where k1-k n k refers to the luminous grayscale value of the luminous pixel corresponding to the display pixel in its respective luminous time slice, yThe target display grayscale value for the displayed pixel.

[0074] S230: If the maximum displayable brightness corresponding to the display pixel is greater than the maximum adjusted brightness, divide the plurality of luminous pixels corresponding to the display pixel into a plurality of pixel groups.

[0075] If the maximum displayable brightness corresponding to the display pixel is greater than the maximum adjusted brightness, it is determined that the target display grayscale value corresponding to the display pixel cannot be directly used as the luminous grayscale value of the multiple luminous pixels corresponding to the display pixel in their respective luminous time slices. At this time, the multiple luminous pixels corresponding to the display pixel can be divided into multiple pixel groups, each of which can include two luminous pixels.

[0076] 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 to take values ​​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.

[0077] 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 l1, l2, l3 and l4 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.

[0078] S240, determining a maximum adjusted display grayscale value corresponding to a display pixel according to a maximum light-emitting grayscale value corresponding to a light-emitting pixel in the display panel, the number of a plurality of pixel groups corresponding to the display pixel, a maximum adjusted brightness, and a maximum displayable brightness.

[0079] According to the maximum luminous grayscale value 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 value corresponding to the display pixels.

[0080] Exemplarily, the maximum adjusted display grayscale value corresponding to the display pixel may be determined by Formula 2, which is as follows:

[0081]

[0082] Among them, m is the maximum adjusted display grayscale value corresponding to the display pixel, G is the maximum luminous grayscale value 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.

[0083] S250 , determining a mapping value corresponding to a display pixel according to the maximum light emitting grayscale value, the maximum adjusted display grayscale value corresponding to the display pixel, and the target display grayscale value.

[0084] For each display pixel, a function operation may be performed according to the maximum luminous grayscale value, the maximum adjusted display grayscale value corresponding to the display pixel, and the target display grayscale value, and the operation result is used as the mapping value corresponding to the display pixel.

[0085] The function calculation process can refer to Formula 3, which is as follows:

[0086]

[0087] Among them, β is the mapping value corresponding to the display pixel, k y is the target display grayscale value of the display pixel, m is the maximum adjusted display grayscale value corresponding to the display pixel, and G is the maximum luminous grayscale value corresponding to the luminous pixel.

[0088] S260 , determining the luminous grayscale value of each luminous pixel in each pixel group corresponding to the display pixel in its own luminous time slice according to the maximum luminous grayscale value and the mapping value corresponding to the display pixel.

[0089] For each display pixel, a function operation is performed according to the maximum luminous grayscale value and the mapping value corresponding to the display pixel to obtain the luminous grayscale value of each luminous pixel in each pixel group corresponding to the display pixel in its own luminous time slice.

[0090] As an implementation method, S260 may include: determining a value interval for each pixel group corresponding to the display pixel based on the maximum luminous grayscale value; for each pixel group corresponding to the display pixel, determining a target value interval for the mapping value corresponding to the display pixel in 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 a 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 luminous grayscale value of each luminous pixel in each pixel group corresponding to the display pixel within its respective luminous time slice based on the respective first sub-mapping functions of each pixel group corresponding to the display pixel.

[0091] 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 values ​​of the luminous pixels in the pixel group can be considered to be consistent. The grayscale values ​​of the pixel groups composed of the luminous pixels near 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).

[0092] Taking into account that when there are bad pixels, the bad pixels have very low brightness or even are not bright, 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 taken as the highest grayscale, and 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.

[0093] For the 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 value m corresponding to the display pixel. At this time, the grayscale modulation range of the display pixel is 0-m.

[0094] 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, +∞].

[0095] 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 display pixel is within ((i-1)·G, i·G], then the pixel group w i The target value interval of is ((i-1)·G, i·G].

[0096] For each pixel group of display pixels, a respective first mapping function corresponds to each pixel group, and the first mapping function of each pixel group corresponds to a plurality of sub-mapping functions corresponding to value intervals. j For example, w1, w2, w3...w j The corresponding relationship between each sub-mapping function and the value interval in the first mapping function is as follows:

[0097]

[0098]

[0099]

[0100] …

[0101]

[0102] …

[0103]

[0104] Among them, it is obvious that the pixel groups w1 and w j The corresponding value interval includes two, pixel groups w1 and w j The corresponding first mapping functions all include respective sub-mapping functions of 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 respective sub-mapping functions of the three value intervals.

[0105] 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 luminous grayscale value of each luminous pixel in each pixel group corresponding to the display pixel in its respective luminous time slice is determined directly through the first sub-mapping function of each pixel group.

[0106] For example, the pixel groups corresponding to the display pixel include two w1, w2 and w3. For the pixel group w1, the target value interval is determined to be β>G, the first sub-mapping function corresponding to the pixel group w1 is determined to be w1=G, and the luminous grayscale value of each luminous pixel in the pixel group w1 in its respective luminous time slice is determined to be G according to the determined first sub-mapping function. For the pixel group w2, the target value interval is determined to be G<β≤2·G, the first sub-mapping function corresponding to the pixel group w2 is determined to be w2=β-G, and the luminous grayscale value of each luminous pixel in the pixel group w2 in its respective luminous time slice is determined to be β-G according to the determined first sub-mapping function. For the pixel group w3, the target value interval is determined to be β>2G, the first sub-mapping function corresponding to the pixel group w3 is determined to be w3=G, and the luminous grayscale value of each luminous pixel in the pixel group w3 in its respective luminous time slice is determined to be G according to the determined first sub-mapping function.

[0107] Due to the poor brightness consistency of multiple pixels, the brightness and value of different pixel groups corresponding to different display pixels are different, wherein the brightness and value of the pixel group refers to the sum of the actual brightness values ​​of each luminous pixel in the pixel value. Therefore, it is necessary to further optimize the process of determining the luminous grayscale value of each luminous pixel in each pixel group corresponding to the display pixel within the respective luminous time slice. At this time, S260 may include: calculating the sum of the actual brightness values ​​of the multiple luminous pixels in each pixel group corresponding to the display pixel as the brightness sum value of each pixel group corresponding to the display pixel; the actual brightness value of the luminous pixel refers to the brightness value when the luminous pixel emits light according to the maximum luminous power; determining the display grayscale range of each pixel group corresponding to the display pixel according to the maximum luminous grayscale value, the maximum adjusted display grayscale value corresponding to the display pixel, and the brightness sum value of each pixel group corresponding to the display pixel; for each pixel group corresponding to the display pixel, determining the target display grayscale range in which the mapping value corresponding to the display pixel is located in the display grayscale range of the pixel group; for each pixel group corresponding to the display pixel, obtaining a second sub-mapping function corresponding to the target display grayscale range of the pixel group from the second mapping function corresponding to the pixel group; the second mapping function corresponding to the pixel group includes a plurality of sub-mapping functions corresponding to the display grayscale range; according to the second sub-mapping function of each pixel group corresponding to the display pixel, determining the luminous grayscale value of each luminous pixel in each pixel group corresponding to the display pixel within the respective luminous time slice.

[0108] When the pixel sequence corresponding to the display pixel is traversed from the middle to the two ends, the brightness and value of the determined pixel group are recorded as b1, b2, b3...b j , that is, pixel group w i The pixel and value are b i , i is any integer between 1 and j.

[0109] Then, the display grayscale boundary value of each pixel group corresponding to the display pixel can be determined according to the maximum luminous grayscale value, the maximum adjusted display grayscale value corresponding to the display pixel, and the brightness and value of each pixel group corresponding to the display pixel in accordance with Formula 4. Formula 4 is as follows:

[0110]

[0111]

[0112]

[0113] …

[0114]

[0115] Among them, u iis the large boundary value among the display grayscale boundary values ​​corresponding to the i-th pixel group (that is, the maximum value of the display grayscale range).

[0116] For each pixel group corresponding to the display pixel, after determining the display grayscale boundary value of the pixel group, the display grayscale range of the pixel group is determined according to the display grayscale boundary value of the pixel group. i , when i is not 1 and j, determine w i The corresponding display grayscale ranges are [0, u i-1 ]、(u i-1 ,u i ] and (u i , +∞]. In addition, the value range of w1 is [0, u1] and (u1, +∞], w j The value range is [0, u j-1 ] and (u j-1 , +∞].

[0117] For each pixel group corresponding to a display pixel, the target display grayscale range of the pixel group refers to the display grayscale range where the mapping value corresponding to the display pixel is located. i , the mapping value corresponding to the pixel is displayed in (u i-1 ,u i ], then the pixel group w i The target display grayscale range is (u i-1 ,u i ].

[0118] For each pixel group of display pixels, a respective second mapping function corresponds to each pixel group, and the second mapping function of each pixel group corresponds to a plurality of sub-mapping functions corresponding to the display grayscale range. j For example, w1, w2, w3...w j The corresponding relationship between each sub-mapping function in the second mapping function and the display grayscale range is as follows:

[0119]

[0120]

[0121]

[0122] …

[0123]

[0124] …

[0125]

[0126] Among them, it is obvious that the pixel groups w1 and w j The corresponding display grayscale range includes two pixel groups w1 and w j The corresponding second mapping functions all include respective sub-mapping functions for two display grayscale ranges, the other pixel groups all correspond to three display grayscale ranges, and the second mapping functions corresponding to the other pixel groups all include respective sub-mapping functions for the three display grayscale ranges.

[0127] For each pixel group corresponding to the display pixel, a second sub-mapping function corresponding to the target display grayscale range of the pixel group is obtained from the second mapping function corresponding to the pixel group, and the luminous grayscale value of each luminous pixel in each pixel group corresponding to the display pixel within its respective luminous time slice is determined directly through the second sub-mapping function of each pixel group.

[0128] For example, the pixel groups corresponding to the display pixel include two w1, w2 and w3. For the pixel group w1, the target display grayscale range is determined to be β>u1, and the first sub-mapping function corresponding to the pixel group w1 is determined to be w1=G. According to the determined first sub-mapping function, the luminous grayscale value of each luminous pixel in the pixel group w1 in its respective luminous time slice is determined to be G. For the pixel group w2, the target display grayscale range is determined to be u1<β≤u2, and the first sub-mapping function corresponding to the pixel group w2 is determined to be According to the determined first sub-mapping function, the luminous grayscale value of each luminous pixel in the pixel group w2 in its respective luminous time slice is determined to be For the pixel group w3, the target display grayscale range is determined to be β>u2, and the first sub-mapping function corresponding to the pixel group w3 is determined to be According to the determined first sub-mapping function, the luminous grayscale value of each luminous pixel in the pixel group w3 in its respective luminous time slice is determined to be

[0129] It should be noted that since it is impossible to brighten the dark spots in the display panel, the concept of the display method (also called Demura algorithm) of this application is to reduce the brightness of the brighter part of the display panel. Therefore, by using the maximum adjusted brightness as the threshold for determination, the brightness of the display pixels brighter than the maximum adjusted brightness is reduced, and the pixels darker than the maximum adjusted brightness remain unchanged.

[0130] S270, controlling the multiple luminous pixels corresponding to each display pixel to emit light according to the luminous grayscale values ​​of the multiple luminous pixels corresponding to each display pixel in their respective luminous time slices; controlling the pixel shift device to move so that the light emitted by the multiple luminous pixels in their respective luminous time slices can be incident on the corresponding display pixel position.

[0131] The description of S270 refers to the description of S130 above and will not be repeated here.

[0132] In this embodiment, each display pixel is affected by n luminous pixels. Therefore, the display method of the present application can also be called an optimization algorithm of n ways Demura.

[0133] In this embodiment, the maximum displayable brightness corresponding to the display pixel is greater than the maximum adjusted brightness, and the luminous grayscale values ​​of the multiple luminous pixels corresponding to the display pixel in their respective luminous time slices are determined by a mapping function, and the luminous grayscale values ​​of the multiple luminous pixels in their respective luminous time slices are determined by the maximum luminous grayscale value and the mapping value corresponding to the display pixel. The accuracy of the luminous grayscale values ​​of the multiple luminous pixels in their respective luminous time slices is high, so that the brightness value output by the display pixel is more consistent with the target display grayscale value, thereby improving the display effect of the display panel.

[0134] In addition, in this embodiment, different luminous pixels are sorted and grouped, and luminous pixels that can emit light with higher brightness are matched with higher grayscales, while luminous pixels with lower actual brightness are matched with low grayscales. This can increase the maximum adjustment brightness of the display pixels, thereby effectively improving the display effect of the display panel.

[0135] In order to explain the technical solution of the present application more clearly, the display method of the present application is described below in conjunction with an exemplary scenario. In this scenario, each display pixel corresponds to 4 luminous pixels (that is, in this scenario, the display method is also called the 4ways Demura optimization algorithm), and the brightness value in this scene is 0-255, and the maximum adjustment brightness corresponding to the display pixel is 160.

[0136] like Fig. 9 As shown, the luminous pixels corresponding to the display pixel e0 are e1, e2, e3 and e4 respectively, and the four luminous pixels are shifted to position e in a time-sharing manner to provide brightness for the display pixel e. The actual brightness values ​​of the luminous pixels e1, e2, e3 and e4 at the maximum luminous power (the maximum luminous grayscale value of the normal luminous pixels is 15) are x1, x2, x3 and x4 respectively, and the maximum displayable brightness of the display pixel e0 is determined to be y according to x1, x2, x3 and x4.

[0137] The target grayscale value that the display pixel e0 needs to display is k y (value range 0-15), the inverse calculation of the luminous grayscale values ​​of the luminous pixels e1, e2, e3 and e4 in their respective luminous time slices are k1, k2, k3, k4 (value range 0-15):

[0138] When y≤160, then k1=k2=k3=k4=ky ;

[0139] When y>160, the brightness of the luminous pixels e1, e2, e3 and e4 are sorted. Since x1≥x2≥x3≥x4, the luminous sequence x1-x2-x3-x4 is obtained. At this time, e1 and e4 are merged into one pixel group, and k1=k4; the luminous pixel e2 and the luminous pixel e3 are combined into one pixel group, and k2=k3; then the pixel group w2 in the middle position of the pixel sequence is used as the low grayscale (k2, k3), and the pixel groups w2 on both sides are used as the high grayscale (k1, k4).

[0140] For display pixel e0, when y>160, according to the maximum luminous grayscale value 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, its brightness is adjusted from (0-y) to (0-160), and the maximum adjusted display grayscale value m of display pixel e0 is obtained.

[0141] At this time, the grayscale range of the display pixel e0 is 0-m. Map the 0-15 grayscale to the 0-m grayscale to obtain the mapping value corresponding to the display pixel e0 For the low gray scale of the display pixel e0 being (k2, k3), the mapping relationship between the first mapping function and the value range corresponding to the pixel group w2 is:

[0142]

[0143] For the high grayscale of the display pixel e0 being (k1, k4), the mapping relationship between the first mapping function and the value range corresponding to the pixel group w1 is:

[0144]

[0145] Furthermore, considering the poor brightness consistency of the four luminous pixels, the above algorithm needs to be further optimized, because the relationship between the actual brightness values ​​of the four pixels is: x1+x4≠x2+x3. To further improve the accuracy, the high grayscale and the low grayscale can be allocated proportionally.

[0146] At this time, when y≤160, no brightness adjustment is required, and k1=k2=k3=k4=k y .

[0147] When y>160, for the display pixel e0, there are two pixel groups corresponding to two display grayscale ranges. At this time, only the segmentation point u1 of the two display grayscale ranges needs to be calculated. 0-u1 is the low-order contribution grayscale, and the high-order contribution grayscale is u1-m. At this time,

[0148] For the low grayscale of the display pixel e0 being (k2, k3), the mapping relationship between the second mapping function corresponding to the pixel group w2 and the display grayscale range is:

[0149]

[0150] For the high grayscale of the display pixel e0 being (k1, k4), the mapping relationship between the first mapping function and the value range corresponding to the pixel group w1 is:

[0151]

[0152] In this scenario, compared with the simple algorithm, the uniformity of the display panel can be greatly improved, but the amount of calculation is larger. It is suitable for situations where the original panel has a large degree of unevenness, many bad pixels, and is not particularly sensitive to power consumption.
