[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. According to the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0030] In the following description, the terms "first / second" only distinguish similar objects and do not represent a specific order for the objects. Understandably, "first / second" can be interchanged with a specific order or sequence when permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field 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.

[0032] Refer to Figure 1 , Figure 1 shows a flowchart of a display method proposed in an embodiment of the present application. The method is for a display device and includes:

[0033] S110. Obtain the display gray scale value and the proportional coefficient corresponding to each display pixel in the image to be displayed.

[0034] Among them, each display pixel corresponds to multiple light-emitting pixels on the display panel; the multiple light-emitting pixels corresponding to the display pixel are divided into multiple light-emitting pixel groups; the multiple light-emitting pixels corresponding to the display pixel provide brightness for the display pixel; the proportional coefficient corresponding to the display pixel is determined according to the preset maximum adjustment brightness, the preset maximum displayable brightness corresponding to the display pixel, and the maximum brightness of each light-emitting pixel group in the multiple light-emitting pixel groups.

[0035] 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 can 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 can refer to a light-emitting pixel under a single-color channel. Among them, the single-color channel can refer to a red channel, a blue channel, or a green channel. For example, in a red display panel, the light-emitting pixel can refer to a light-emitting pixel under the 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 can include multiple light-emitting pixels of a single color channel. For example, the display panel can include a red light-emitting pixel under the red channel, a blue light-emitting pixel under the blue channel, and a green light-emitting pixel under the green channel.

[0036] In this embodiment, the display panel can be a display panel having a pixel offset device (for example, a device in the XPR offset 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, so as to achieve pixel displacement).

[0037] When the light-emitting pixels in the display panel emit light, the pixel offset device also offsets, thereby changing the optical path of the light-emitting pixels, so that the light emitted by multiple light-emitting pixels can be incident on the same display position along the changed optical path. This display position serves as the display pixel corresponding to multiple light-emitting pixels. That is, the display effect of any display pixel in the image to be displayed is the result of the combined action of multiple light-emitting pixels corresponding to the display pixel. That is, any display pixel in the image to be displayed provides brightness through multiple light-emitting pixels corresponding to the display pixel. Among them, one pixel in the image to be displayed serves as one display pixel. That is, each light-emitting pixel on the display panel emits light according to a specified gray-scale value to display a specified brightness. At the same time, the pixel offset device changes the optical path propagation direction of these light-emitting pixels, and time-divisionally displaces the light emitted by multiple light-emitting pixels to the same display pixel.

[0038] It is worth mentioning that when the pixel offset device in this application offsets, it moves the optical paths of multiple light-emitting pixels corresponding to each display pixel to the position where the display pixel is located. That is to say, the purpose of the offset of the pixel offset device is to change the optical paths of multiple light-emitting pixels corresponding to each display pixel, so that the light emitted by multiple light-emitting pixels corresponding to each display pixel can be incident on the same display position along the changed optical path.

[0039] For example, the case where a single display pixel is provided with brightness by four light-emitting pixels. The light-emitting pixels on the backplane of the display panel change the optical path direction through the pixel offset device, so that the optical path of the same light-emitting pixel moves to different positions in the image plane.

[0040] It can be understood that when the display panel includes light-emitting pixels under different color channels and the image to be displayed includes display pixels under different color channels, multiple light-emitting pixels corresponding to a display pixel under a single color channel also belong to the light-emitting pixels under the single color channel. For example, the red display pixel under the red color channel corresponds to multiple red light-emitting pixels under the red color channel.

[0041] Such as Figure 2 As shown, the light-emitting pixels (represented by solid circles) corresponding to the display pixel A (represented by a dotted circle) on the display panel include 1, 2,..., n. After the optical paths of the light-emitting pixels 1, 2,..., n pass through the pixel offset device, the optical paths move to the position of the display pixel A in the image plane, realizing that n light-emitting pixels provide brightness for a display pixel A. At this time, the maximum brightness of the display pixel A Among them, k i is the i-th light-emitting pixel corresponding to the display pixel A.

[0042] For multiple light-emitting pixels corresponding to each display pixel, the multiple light-emitting pixels corresponding to the display pixel can be evenly divided to obtain multiple light-emitting pixel groups corresponding to the display pixel. For example, if there are 8 light-emitting pixels corresponding to the display pixel, the 8 light-emitting pixels are evenly divided to obtain two light-emitting pixel groups corresponding to the display pixel, and each light-emitting pixel group includes 4 light-emitting pixels.

[0043] Each display pixel in the image to be displayed corresponds to its own display gray level value. The display gray level value of the display pixel refers to the actual gray level value of the display pixel in the image to be displayed, which can be directly determined by the display device according to the image to be displayed. The gray level value can be data of 4 bits, 8 bits, 16 bits, etc. For example, when the gray level value is 4 bits, the gray level value includes a total of 15 gray level values from 0 to 15. It can be a division of the gray level brightness range that the display pixel can display according to requirements to obtain multiple gray level ranges, and each gray level range is indicated by a gray level value. Since the content displayed by different display pixels in the image to be displayed may be different, the display gray level values corresponding to different display pixels may be different.

[0044] Each display pixel in the image to be displayed corresponds to its own proportionality coefficient. For each display pixel, the proportionality coefficient corresponding to the display pixel can be determined according to the preset maximum adjustable brightness, the preset maximum displayable brightness corresponding to the display pixel, and the maximum brightness of each light-emitting pixel group among the multiple light-emitting pixel groups corresponding to the display pixel.

[0045] The preset maximum adjustable brightness corresponding to the display pixel can be a value set based on requirements. For example, when the brightness range of the display pixel is 0 - 255, the preset maximum adjustable brightness can be 240; the preset maximum displayable brightness corresponding to the display pixel is the highest brightness that the display pixel can display. For example, when the brightness range of the display pixel is 0 - 255, the preset maximum adjustable brightness can be 255.

[0046] For each light-emitting pixel group among the multiple light-emitting pixel groups corresponding to the display pixel, the maximum brightness of the light-emitting pixel group can be the maximum value or the average value among the maximum brightnesses of the individual light-emitting pixels in the light-emitting pixel group. The maximum brightness of the light-emitting pixel refers to the highest brightness that the light-emitting pixel can display. For example, if the light-emitting pixel group includes 4 light-emitting pixels with maximum brightnesses of 50, 70, 60, and 80 in sequence, at this time, the maximum brightness of the light-emitting pixel group can be 80 (the maximum value) or 65 (the average value rounded to the nearest integer).

[0047] For each light-emitting pixel group corresponding to a display pixel, the maximum display gray level of the light-emitting pixel group can be the maximum value or the average value among the maximum display gray levels of the respective light-emitting pixels in the light-emitting pixel group. The maximum display gray level of a light-emitting pixel refers to the maximum gray level that the light-emitting pixel can display. For example, if a light-emitting pixel group includes 4 light-emitting pixels with maximum display gray levels of 240, 245, 244, and 250 in sequence, at this time, the maximum display gray level of the light-emitting pixel group can be 250 (the maximum value) or 245 (the average value rounded to the nearest integer).

[0048] In this embodiment, for each display pixel, the average of the maximum brightnesses of the multiple light-emitting pixel groups corresponding to the display pixel can be calculated to obtain the average display brightness corresponding to the display pixel. Then, the ratio of the preset maximum adjustment brightness and the preset maximum display brightness corresponding to the display pixel is calculated to obtain the brightness ratio corresponding to the display pixel. The product of the brightness ratio corresponding to the display pixel and the average display brightness is calculated to obtain the proportionality coefficient corresponding to the display pixel. In this way, by traversing all display pixels, the proportionality coefficients of each display pixel are obtained respectively.

[0049] S120. Determine the target display gray level of each light-emitting pixel group in the multiple light-emitting pixel groups corresponding to each display pixel according to the display gray level value and the proportionality coefficient corresponding to each display pixel.

[0050] For each display pixel, the target display gray level of each light-emitting pixel group in the multiple light-emitting pixel groups corresponding to the display pixel can be determined according to the display gray level value and the proportionality coefficient corresponding to the display pixel. One light-emitting pixel group corresponding to a display pixel corresponds to one target display gray level, and the actual display brightness of each light-emitting pixel in the light-emitting pixel group is the target display gray level corresponding to the light-emitting pixel group.

[0051] In this embodiment, for each display pixel, the product of the display gray level value and the proportionality coefficient corresponding to the display pixel is calculated, and then this product is multiplied by the respective product coefficients of each display pixel group corresponding to the display pixel to obtain the respective target display gray levels of each display pixel group corresponding to the display pixel. Among them, the respective product coefficients of each display pixel group can be values set based on requirements.

[0052] For example, the light-emitting pixel groups corresponding to the display pixel xa are the light-emitting pixel group a1 and the light-emitting pixel group a2. The display gray level value of the display pixel xa and the proportionality coefficient are multiplied to obtain the product t1. The product t1 is multiplied by the product coefficient of the light-emitting pixel group a1 to obtain the target display gray level of the light-emitting pixel group a1. Similarly, the product t1 is multiplied by the product coefficient of the light-emitting pixel group a2 to obtain the target display gray level of the light-emitting pixel group a2.

[0053] S130. Control the light-emitting pixels in each light-emitting pixel group corresponding to each display pixel to emit light according to the target display gray level of each light-emitting pixel group in the multiple light-emitting pixel groups corresponding to each display pixel; control the pixel offset device to move so that the light emitted by each light-emitting pixel in the display panel can be incident on the corresponding display pixel position.

[0054] As described above, according to the target display gray level of each light-emitting pixel group in the multiple light-emitting pixel groups corresponding to a display pixel, the actual display brightness of each light-emitting pixel in the multiple light-emitting pixel groups corresponding to the display pixel can be determined. According to the actual display brightness of the multiple light-emitting pixels corresponding to the display pixel within their respective light-emitting time slices, control the multiple light-emitting pixels corresponding to the display pixel to emit light within their respective light-emitting time slices, and control the pixel offset device of the display panel to offset, so that the light emitted by the multiple light-emitting pixels corresponding to the display pixel within their respective light-emitting time slices can be incident on the corresponding display pixel position, so that the display pixel can display the image to be displayed, and the uniformity of the image to be displayed displayed by the display panel is better.

[0055] The light-emitting time slice of a light-emitting pixel refers to the time period during which the light-emitting pixel emits light within one frame of the image. For example, in the case where a single display pixel is provided with brightness by four light-emitting pixels. The light-emitting pixels on the backplane of the display panel change the optical path direction through an optical dithering device, so that the optical path of the same light-emitting pixel moves to different positions in the image plane. At this time, the display duration of one frame of the image is divided into four light-emitting time slices.

[0056] For example, the display pixel x1 corresponds to four light-emitting pixels f1, f2, f3, and f4. The light-emitting time slices of the four light-emitting 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. Determine that the actual display brightnesses of the four light-emitting pixels f1, f2, f3, and f4 corresponding to the display pixel x1 are h1, h2, h3, and h4 respectively. At this time, the actual display brightness of the light-emitting pixel f1 in the light-emitting time slice t1 is h1, the actual display brightness of the light-emitting pixel f2 in the light-emitting time slice t2 is h2, the actual display brightness of the light-emitting pixel f3 in the light-emitting time slice t3 is h3, and the actual display brightness of the light-emitting pixel f4 in the light-emitting time slice t4 is h4. And the order of the light-emitting time slices is t1 - t2 - t3 - t4.

[0057] In this embodiment, each display pixel in the image to be displayed corresponds to multiple display pixels in the display panel. The multiple pixels are divided into multiple pixel groups. For each pixel group, its target display gray level is determined. Through the target display gray levels of each light-emitting pixel group in the multiple light-emitting pixel groups, the light-emitting pixels in each light-emitting pixel group corresponding to each display pixel are controlled to emit light. At the same time, the pixel offset device is controlled to move so that the light emitted by each light-emitting pixel in the display panel can be incident on the corresponding display pixel position. By means of the pixel offset device, the uniformity of the image displayed on the display panel is improved, thereby improving the display effect of the display panel.

[0058] At the same time, when there are defective pixels among the multiple light-emitting pixels corresponding to each display pixel, the light can still be emitted through the actual display brightness of the other light-emitting pixels corresponding to each display pixel. This avoids the situation where, in the case of a one-to-one correspondence between the light-emitting pixels and the display pixels, the display pixel corresponding to the defective light-emitting pixel cannot be normally displayed, thereby improving the degree of fit between the actual brightness of the display pixel and the display gray level value of the image to be displayed, and further improving the display effect of the image to be displayed on the display panel.

[0059] Refer to Figure 3 , Figure 3 shows a flowchart of a display method proposed in another embodiment of the present application. The method is used for a display device and includes:

[0060] S210. Extract the first mapping parameter and the second mapping parameter corresponding to the display pixel from the stored parameters; process the first mapping parameter through the first inverse mapping function corresponding to the first mapping function to obtain the brightness ratio data corresponding to the display pixel; process the second mapping parameter through the second inverse mapping function corresponding to the second mapping function to obtain the brightness correction data corresponding to the display pixel.

[0061] In this embodiment, an electronic device (the electronic device can be a device different from the display device) divides the multiple light-emitting pixels corresponding to the display pixel in the display panel into multiple light-emitting pixel groups (the division process can refer to the description of S110 above and will not be elaborated here). Then, the electronic device determines the brightness ratio data corresponding to the display pixel according to the sum of the maximum brightnesses of the multiple light-emitting pixels in each light-emitting pixel group corresponding to the display pixel.

[0062] For each of a plurality of light-emitting pixel groups corresponding to a display pixel, the plurality of light-emitting pixels in the light-emitting pixel group may refer to all the light-emitting pixels in the light-emitting pixel group. That is, the maximum brightnesses of all the light-emitting pixels in the light-emitting pixel group can be summed to obtain the sum of the maximum brightnesses of the light-emitting pixel group. For each display pixel, all the light-emitting pixel groups corresponding to the display pixel are traversed to obtain the sum of the maximum brightnesses of each of all the light-emitting pixel groups corresponding to the display pixel. Then, based on the sum of the maximum brightnesses of each of all the light-emitting pixel groups corresponding to the display pixel, the brightness ratio data corresponding to the display pixel is determined.

[0063] As an implementation, a display pixel corresponds to two light-emitting pixel groups; determining the brightness ratio data corresponding to the display pixel according to the sum of the maximum brightnesses of the plurality of light-emitting pixels in each of the plurality of light-emitting pixel groups corresponding to the display pixel may include: calculating the ratio of the sum of the maximum brightnesses of the plurality of light-emitting pixels in the target light-emitting pixel group corresponding to the display pixel to the sum of the maximum brightnesses of the plurality of light-emitting pixels in the other light-emitting pixel groups to obtain the brightness ratio data corresponding to the display pixel. Wherein, the target light-emitting pixel group is any one of the plurality of light-emitting pixel groups corresponding to the display pixel; the other light-emitting pixel groups refer to the light-emitting pixel groups corresponding to the display pixel excluding the target light-emitting pixel group.

[0064] For example, a display pixel corresponds to n light-emitting pixels, the n light-emitting pixels are divided into two light-emitting pixel groups, each light-emitting pixel group includes n / 2 light-emitting pixels, any one of the light-emitting pixel groups is selected as the target light-emitting pixel group, and the other one is the other light-emitting pixel group. Calculate the ratio b1 / b2 of the sum of the maximum brightnesses b1 of the plurality of light-emitting pixels in the target light-emitting pixel group to the sum of the maximum brightnesses b2 of the plurality of light-emitting pixels in the other light-emitting pixel group as the brightness ratio data corresponding to the display pixel.

[0065] After the electronic device determines the brightness ratio data corresponding to the display pixel, it can also determine the pixel group adjustment gray level of the other light-emitting pixel groups corresponding to the display pixel according to the maximum displayable gray level of the target light-emitting pixel group corresponding to the display pixel, the preset maximum adjustment brightness corresponding to the display pixel, the preset maximum displayable brightness, and the brightness ratio data; wherein, the target light-emitting pixel group is any one of the plurality of light-emitting pixel groups corresponding to the display pixel; the other light-emitting pixel groups refer to the light-emitting pixel groups corresponding to the display pixel excluding the target light-emitting pixel group.

[0066] Specifically, according to the maximum display gray level of the target light-emitting pixel group corresponding to the display pixel, the preset maximum adjustment brightness, the preset maximum display brightness, and the brightness ratio data corresponding to the display pixel, determine the pixel group adjustment gray level of other light-emitting pixel groups corresponding to the display pixel, including: determining the brightness adjustment coefficient corresponding to the display pixel according to the preset maximum adjustment brightness and the preset maximum display brightness corresponding to the display pixel; determining the gray level adjustment coefficient corresponding to the display pixel according to the brightness adjustment coefficient and the brightness ratio data corresponding to the display pixel; and determining the pixel group adjustment gray level of other light-emitting pixel groups corresponding to the display pixel according to the gray level adjustment coefficient and the maximum display gray level of the target light-emitting pixel group corresponding to the display pixel.

[0067] Among them, the ratio of the preset maximum adjustment brightness and the preset maximum display brightness corresponding to the display pixel can be calculated to obtain the brightness adjustment coefficient corresponding to the display pixel; at the same time, the sum of the preset constant (such as 1) and the brightness ratio data corresponding to the display pixel is calculated, and the difference between the sum and the brightness ratio data corresponding to the display pixel is obtained to get the gray level adjustment coefficient corresponding to the display pixel. Then, the gray level adjustment coefficient corresponding to the display pixel is multiplied by the maximum display gray level of the target light-emitting pixel group corresponding to the display pixel, and finally, the product result is rounded to obtain the pixel group adjustment gray level of other light-emitting pixel groups corresponding to the display pixel.

[0068] For example, when the preset constant is 1, the process of calculating the pixel group adjustment gray level of other light-emitting pixel groups corresponding to the display pixel can be briefly described as Formula 1, and Formula 1 is as follows:

[0069]

[0070] Among them, h is the pixel group adjustment gray level of other light-emitting pixel groups corresponding to the display pixel, g is the maximum display gray level of the target light-emitting pixel group corresponding to the display pixel, m is the brightness ratio data corresponding to the display pixel, k A is the preset maximum display brightness corresponding to the display pixel, k t is the preset maximum adjustment brightness corresponding to the display pixel, round() is the rounding function, and at this time, the range of h is determined to be 0 - g.

[0071] After the electronic device determines the pixel group adjustment gray level of other light-emitting pixel groups corresponding to the display pixel, it can determine the brightness correction data corresponding to the display pixel according to the maximum display gray level of the target light-emitting pixel group corresponding to the display pixel and the pixel group adjustment gray level of other light-emitting pixel groups. Specifically, the difference between the maximum display gray level of the target light-emitting pixel group corresponding to the display pixel and the pixel group adjustment gray level of other light-emitting pixel groups can be calculated to obtain the brightness correction data corresponding to the display pixel. That is, the brightness correction data j corresponding to the display pixel = g - h.

[0072] After that, the electronic device can process the brightness ratio data corresponding to the display pixels through the first mapping function to obtain the first mapping parameter corresponding to the display pixels; process the brightness correction data corresponding to the display pixels through the second mapping function to obtain the second mapping parameter corresponding to the display pixels; splice the first mapping parameter and the second mapping parameter corresponding to the display pixels to obtain the storage parameter corresponding to the display pixels, and then the electronic device sends the storage parameter to the display device, and the display device caches the storage parameter.

[0073] Among them, in this embodiment, the display device can process the brightness ratio data corresponding to the display pixels through the first mapping function to obtain the processing result x m (0 ≤ x m ≤ <2 x -1), and then map the processing result x m to binary data to obtain the first mapping parameter. Similarly, the display device can process the brightness correction data corresponding to the display pixels through the second mapping function to obtain the processing result y i (0 ≤ y i ≤ <2 y -1), and then map the processing result y i to binary data to obtain the second mapping parameter. At this time, the first mapping function refers to any function that maps the brightness ratio data corresponding to the display pixels within 0 ≤ x m ≤ <2 x -1, and the second mapping function refers to any function that maps the brightness ratio data corresponding to the display pixels within 0 ≤ y i ≤ <2 y -1.

[0074] After that, the first mapping parameter and the second mapping parameter can be spliced to obtain the storage parameter, and this storage parameter can also be called demura data (data used to repair mura in the display panel. In the field of mura display panels, it means that the brightness of the display panel is uneven, resulting in various trace phenomena). In this embodiment, when the target format is binary, the format of the storage parameter can be as Figure 4 shown.

[0075] When the display device needs to project a projection image, the display device obtains the cached storage parameter. After that, the display device can directly extract the first mapping parameter and the second mapping parameter corresponding to the display pixels from the storage parameter corresponding to the display pixels. After that, restore the binary first mapping parameter to the processing result x m , and restore the binary second mapping parameter to the processing result y i , and then, through the first inverse mapping function corresponding to the first mapping function (used to map the processing result x mRestore it to luminance ratio data) to process the processing result x m Perform processing to obtain the luminance ratio data corresponding to the display pixel; through the second inverse mapping function corresponding to the second mapping function (for restoring the processing result y i Restore it to luminance correction data) to process the processing result y i Perform processing to obtain the luminance correction data corresponding to the display pixel.

[0076] S220. Determine the proportionality coefficient corresponding to the display pixel according to the luminance ratio data and the luminance correction data corresponding to the display pixel.

[0077] In this embodiment, the proportionality coefficient corresponding to the display pixel can be determined according to the luminance ratio data corresponding to the display pixel, the maximum luminance of the target light-emitting pixel group corresponding to the display pixel, and the luminance correction data corresponding to the display pixel.

[0078] Specifically, the adjusted gray level of the target light-emitting pixel group corresponding to the display pixel can be determined according to the luminance ratio data corresponding to the display pixel and the maximum displayable gray level of the target light-emitting pixel group; the adjusted gray level of the other light-emitting pixel groups corresponding to the display pixel can be determined according to the luminance correction data corresponding to the display pixel and the maximum displayable gray level of the target light-emitting pixel group; the proportionality coefficient corresponding to the display pixel can be determined according to the adjusted gray levels of the other light-emitting pixel groups corresponding to the display pixel, the adjusted gray level of the target light-emitting pixel group, and the maximum displayable gray level.

[0079] The luminance ratio data corresponding to the display pixel and the maximum displayable gray level of the target light-emitting pixel group can be multiplied to obtain the adjusted gray level of the target light-emitting pixel group corresponding to the display pixel, that is, the adjusted gray level g1 of the target light-emitting pixel group corresponding to the display pixel = g×m, where m is the luminance ratio data corresponding to the display pixel; the difference between the maximum displayable gray level of the target light-emitting pixel group corresponding to the display pixel and the luminance correction data corresponding to the display pixel is calculated to obtain the adjusted gray level of the other light-emitting pixel groups corresponding to the display pixel, that is, the adjusted gray level g2 of the other light-emitting pixel groups corresponding to the display pixel = g - j.

[0080] After that, continue to determine the proportionality coefficient corresponding to the display pixel according to the adjusted gray level g2 of the other light-emitting pixel groups corresponding to the display pixel, the adjusted gray level g1 of the target light-emitting pixel group, and the maximum displayable gray level g. In this embodiment, the gray level sum (g1 + g2) of calculating the adjusted gray level g2 of the other light-emitting pixel groups corresponding to the display pixel and the adjusted gray level g1 of the target light-emitting pixel group can be used. The adjusted gray level g1 of the target light-emitting pixel group corresponding to the display pixel is compared with the gray level sum (g1 + g2), and the ratio is multiplied by the maximum displayable gray level g of the target light-emitting pixel group to obtain the proportionality coefficient of the display pixel. At this time, the calculation process of the proportionality coefficient of the display pixel is simplified to formula two, and formula two is as follows:

[0081]

[0082] Among them, g k is the proportionality coefficient of the display pixel.

[0083] It can be understood that for each display pixel, the preset maximum adjustment brightness, the preset maximum displayable brightness corresponding to the display pixel, and the maximum displayable gray level of each light-emitting pixel group in the multiple light-emitting pixel groups can be obtained in advance, and then according to the steps of the foregoing S210-S220, the proportionality coefficient of the display pixel is determined, and all display pixels are traversed to obtain the proportionality coefficients of each display pixel.

[0084] S230. Obtain the display gray level value corresponding to each display pixel in the image to be displayed.

[0085] Among them, the description of S230 refers to the description of S110 above and will not be elaborated here.

[0086] S240. Determine the target display gray level of each light-emitting pixel group in each display pixel corresponding to each display pixel according to the display gray level value corresponding to each display pixel and the proportionality coefficient.

[0087] Among them, the display pixel corresponds to two light-emitting pixel groups; if the display gray level value corresponding to the display pixel is less than the proportionality coefficient, calculate the ratio of the display gray level value corresponding to the display pixel to the proportionality coefficient, and calculate the product of the ratio and the maximum displayable gray level of the target light-emitting pixel group corresponding to the display pixel as the target display gray level of the target light-emitting pixel group corresponding to the display pixel, and determine the preset display brightness value as the target display gray level of the other light-emitting pixel groups corresponding to the display pixel; if the display gray level value corresponding to the display pixel is not less than the proportionality coefficient, determine the maximum displayable gray level of the target light-emitting pixel group corresponding to the display pixel as the target display gray level of the target light-emitting pixel group corresponding to the display pixel, and determine the product of the difference ratio of the display pixel and the adjustment gray level of the other light-emitting pixel groups of the display pixel as the target display gray level of the other light-emitting pixel groups corresponding to the display pixel; the difference ratio is the ratio of the first difference and the second difference corresponding to the display pixel, the first difference is the difference between the display gray level value corresponding to the display pixel and the proportionality coefficient, and the second difference is the difference between the maximum displayable gray level of the target light-emitting pixel group corresponding to the display pixel and the proportionality coefficient. The preset display brightness value can be 0.

[0088] For example, the display pixel corresponds to two light-emitting pixel groups. When the display gray level value of display pixel A is g A , the target display gray level corresponding to the target light-emitting pixel group can be calculated as g A1 , and the target display gray level corresponding to the other light-emitting pixel groups is g A2, The process of determining the target display gray level corresponding to the target light-emitting pixel group and the target display gray levels corresponding to other light-emitting pixel groups can be briefly described by Equation 3, as follows:

[0089]

[0090]

[0091] Exemplarily, as Figure 5 shown, the light-emitting pixels corresponding to display pixel B are light-emitting pixel c1 and light-emitting pixel c2. Among them, light-emitting pixel c1 is divided into one light-emitting pixel group, and light-emitting pixel c2 is divided into one light-emitting pixel group. The maximum displayable gray levels of light-emitting pixel c1 and light-emitting pixel c2 are 70 and 100 respectively; the gray levels of light-emitting pixel c1 and light-emitting pixel c2 are 8-bit data, that is, the gray level values are 0-255. At this time, 4-bit data is used to record the luminance ratio data m. If the first mapping function is x m = round(15×m - 8), the determined processing result x m is 3, and it is converted to the first mapping parameter 0011 in binary.

[0092] The preset maximum displayable luminance k A corresponding to display pixel B is 80. According to the foregoing method, the pixel group adjustment gray level h corresponding to the other light-emitting pixel groups of the display pixel is calculated to be 230. If the second mapping function is y j = round(j / 8), then the processing result y i corresponding to display pixel B is 3. The processing result y i is converted to the second mapping parameter in binary as 0011. At this time, the storage parameters are as Figure 6 shown, that is, the first four bits are the first mapping parameter, and the last four bits are the second mapping parameter.

[0093] Based on the foregoing storage parameters, the first mapping parameter and the second mapping parameter are extracted, the luminance ratio data and the luminance correction data are restored, and the proportionality coefficient is further calculated; when the display gray level value required to be displayed by display pixel B is 200, it is determined that the actual display luminances of light-emitting pixel c1 and light-emitting pixel c2 are 255 and 141 respectively.

[0094] S250. According to the target display gray levels of each light-emitting pixel group in the multiple light-emitting pixel groups corresponding to each display pixel, control the light-emitting pixels in each light-emitting pixel group in the multiple light-emitting pixel groups corresponding to each display pixel to emit light; control the pixel offset device to move so that the light emitted by each light-emitting pixel in the display panel can be incident on the corresponding display pixel position.

[0095] Among them, the description of S250 refers to the description of S130 above, which will not be elaborated here.

[0096] In this embodiment, according to the preset maximum adjustment brightness, the preset maximum displayable brightness corresponding to the display pixel, and the maximum brightness of each light-emitting pixel group among the multiple light-emitting pixel groups, the proportionality coefficient corresponding to the display pixel is determined. The proportionality coefficient corresponding to the display pixel can accurately indicate the relationship between the display gray level value of the display pixel and the target display gray level of each light-emitting pixel group among the multiple light-emitting pixel groups corresponding to the display pixel, so that the target display gray level of the light-emitting pixel group determined according to the display gray level value and the proportionality coefficient corresponding to the display pixel is more accurate, improving the display effect of the image to be displayed.

[0097] At the same time, the brightness adjustment coefficient and the brightness ratio data corresponding to the display pixel are processed through a mapping function to obtain storage parameters, and the storage parameters are cached, realizing the preprocessing of the storage parameters, so as to directly obtain the cached storage parameters to calculate the proportionality coefficient, avoiding the situation of low efficiency in obtaining the proportionality coefficient caused by real-time calculation of the storage parameters when displaying the image to be displayed, and improving the processing efficiency of the image to be displayed.
