[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. According to the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] In the following description, the terms "first / second" involved 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 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.

[0032] 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.

[0033] Refer to Figure 1 , Figure 1 The flowchart of a display method proposed in an embodiment of the present application is shown. The method is for a display device and includes:

[0034] S110. Obtain the display gray level of the display pixels in the image to be displayed.

[0035] Among them, each display pixel in the image to be displayed corresponds to a plurality of light-emitting pixels in the display panel; the plurality of light-emitting pixels corresponding to the display pixel emit light during their respective frame display periods to provide brightness for the display pixel.

[0036] 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, where 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 red light-emitting pixels under the red channel, blue light-emitting pixels under the blue channel, and green light-emitting pixels under the green channel.

[0037] 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).

[0038] When the light-emitting pixels in the display panel emit light, the pixel offset device also offsets, so that the optical path of the light-emitting pixels changes, and it is possible to make the light emitted by multiple light-emitting pixels 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 to-be-displayed image is the result of the combined action of the multiple light-emitting pixels corresponding to the display pixel. That is, any display pixel in the to-be-displayed image provides brightness through the multiple light-emitting pixels corresponding to the display pixel. Among them, one pixel in the to-be-displayed image serves as a 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.

[0039] It is worth mentioning that when the pixel offset device in the present 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 pixel offset device offsetting 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.

[0040] 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.

[0041] 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, the multiple light-emitting pixels corresponding to the display pixels under a single color channel also belong to the light-emitting pixels under the single color channel. For example, the red display pixels under the red color channel correspond to multiple red light-emitting pixels under the red color channel.

[0042] As Figure 2 shown, the light-emitting pixels (represented by solid circles) corresponding to the display pixel A (represented by a dashed 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 on the image plane, so that n light-emitting pixels provide brightness for one display pixel A. At this time, the maximum brightness of the display pixel A where k i is the i-th light-emitting pixel corresponding to the display pixel A.

[0043] The frame display period refers to the period during which the multiple light-emitting pixels corresponding to each display pixel need to emit light. Among them, the duration of the light-emitting period of each light-emitting pixel is the duration of one frame of the picture. For example, one display pixel corresponds to four light-emitting pixels, and one second includes 60 frames of pictures. The frame display period of the first light-emitting pixel corresponding to the display pixel is the first 1 / 60 s, and the frame display period of the 3rd light-emitting pixel corresponding to the display pixel is the period from the 3 / 60 s to the end of the 3 / 60 s.

[0044] Each pixel in the image to be displayed is used as a display pixel, and the gray level of the display pixel in the image to be displayed is the light-emitting gray level. The gray level is also called gray scale. The gray scale uses the black tone to represent the object, that is, uses black as the reference color, and different saturations of black are used to display the image. Each gray-scale object has a brightness value from 0% (white) to 100% (black).

[0045] The gray-level value can be a numerical value used to indicate the gray level. The data of the gray-level value can be 4 bits, 8 bits, or 16 bits. 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, resulting in multiple gray-level ranges, and each gray-level range is indicated by a gray-level value. The content displayed by different display pixels in the image to be displayed may be different. Therefore, the display gray-level values corresponding to different display pixels may be different.

[0046] In this embodiment, the light-emitting pixels corresponding to the display pixel emit light during their respective corresponding frame display periods, so as to provide brightness for the display pixel, so that the display pixel can display the display gray level.

[0047] S120. Generate multiple emission gray levels corresponding to a display pixel according to the display gray level of the display pixel; determine the target emission gray level of each emission pixel corresponding to the display pixel within its respective frame display period from the multiple emission gray levels corresponding to the display pixel according to the emission pixel serial number attribute of each of the multiple emission pixels corresponding to the display pixel.

[0048] For each display pixel, determine multiple emission gray levels corresponding to the display pixel according to the display gray level corresponding to the display pixel. Wherein, the number of emission gray levels corresponding to each display pixel does not exceed the number of emission pixels corresponding to the display pixel, that is, there may be multiple emission pixels sharing one emission gray level among the multiple emission pixels corresponding to each display pixel.

[0049] Optionally, S120 may include: generating multiple emission gray levels corresponding to the display pixel according to the display gray level of the display pixel and the maximum displayable gray level of the multiple emission pixels corresponding to the display pixel. Wherein, the maximum displayable gray levels of different emission pixels in the display panel may be the same; the maximum displayable gray level of an emission pixel may refer to the gray level when the emission pixel in the display panel displays the maximum brightness value, and the maximum displayable gray levels of different emission pixels may be the same. For example, when the gray level is represented by 0 - 255, the maximum displayable gray level of all emission pixels in the display panel may be 255.

[0050] After determining the maximum displayable gray level of the emission pixels in the display panel, the multiple emission gray levels corresponding to each display pixel can be determined in combination with the display gray level of each display pixel and the maximum displayable gray level of the emission pixels.

[0051] In an embodiment, generating multiple emission gray levels corresponding to the display pixel according to the display gray level of the display pixel and the maximum displayable gray level of the multiple emission pixels corresponding to the display pixel includes: obtaining the actual display brightness of the display pixel according to the display gray level of the display pixel; determining the multiple emission gray levels corresponding to the display pixel according to the actual display brightness of the display pixel, the maximum displayable gray levels of the multiple emission pixels corresponding to the display pixel respectively, and the actual maximum brightness.

[0052] Wherein, the actual display brightness of the display pixel refers to the brightness value of the display pixel when the display pixel in the to-be-displayed image displays the corresponding display gray level value, and can be directly determined from the to-be-displayed image. The actual maximum brightness of the emission pixel refers to the actual brightness of the emission pixel when the emission pixel emits light according to the maximum displayable gray level. The actual maximum brightness of different emission pixels may be different. It is possible to control each emission pixel in the display panel to emit light according to the maximum displayable gray level, and then determine the actual maximum brightness of each emission pixel according to the emission effect of each emission pixel.

[0053] After determining the actual display brightness of each display pixel according to the image to be displayed, for each display pixel, multiple emission gray levels corresponding to the display pixel can be determined by integrating the actual display brightness of the display pixel, the maximum displayable gray level of the light-emitting pixel, and the actual maximum brightness of the light-emitting pixel corresponding to the display pixel. By traversing all the display pixels, multiple emission gray levels of all the display pixels can be obtained.

[0054] Optionally, the multiple emission gray levels corresponding to the display pixel include a first emission gray level and a second emission gray level; determining the multiple emission gray levels corresponding to the display pixel according to the actual display brightness of the display pixel, the maximum actually displayable brightness of each of the multiple light-emitting pixels corresponding to the display pixel, and the actual maximum brightness includes: dividing the multiple light-emitting pixels corresponding to the display pixel into a first light-emitting pixel group and a second light-emitting pixel group, where the light-emitting pixel serial number attribute of each light-emitting pixel in the first light-emitting pixel group is odd, and the light-emitting pixel serial number attribute of each light-emitting pixel in the second light-emitting pixel group is even; determining the brightness sum value of the first light-emitting pixel group according to the sum of the actual maximum brightness of all the light-emitting pixels in the first light-emitting pixel group; if the brightness sum value of the first light-emitting pixel group is not less than the actual display brightness corresponding to the display pixel, obtaining the maximum actually displayable brightness corresponding to the light-emitting pixels in the first light-emitting pixel group as the first actual display brightness corresponding to the display pixel; or, if the brightness sum value of the first light-emitting pixel group is less than the actual display brightness corresponding to the display pixel, calculating the ratio of the first product to the first sum value as the second actual display brightness corresponding to the display pixel; the first product is the product of the total number of light-emitting pixels corresponding to the display pixel, the actual display brightness corresponding to the display pixel, and the maximum actually displayable brightness corresponding to the light-emitting pixels in the first light-emitting pixel group, and the first sum value is the sum of the actual maximum brightness of all the light-emitting pixels in the first light-emitting pixel group; if the brightness sum value of the first light-emitting pixel group is not less than the actual display brightness corresponding to the display pixel, obtaining a preset gray level value as the second actual display brightness corresponding to the display pixel; or, if the brightness sum value of the first light-emitting pixel group is less than the actual display brightness corresponding to the display pixel, calculating the ratio of the second product to the second sum value as the second actual display brightness corresponding to the display pixel; the second product is the product of the difference value and the maximum actually displayable brightness corresponding to the light-emitting pixels in the second light-emitting pixel group; the difference value is the difference between the product of the number of light-emitting pixels corresponding to the display pixel and the actual display brightness corresponding to the display pixel and the first sum value; the second sum value is the sum of the actual maximum brightness of all the light-emitting pixels in the second light-emitting pixel group. Among them, the preset gray level value can be zero.

[0055] Exemplarily, when each display pixel corresponds to four light-emitting pixels, the process of determining the first emission gray level and the second emission gray level corresponding to the display pixel refers to Formula 1, and Formula 1 is as follows:

[0056]

[0057]

[0058] Among them, g1 is the first emission gray level, g2 is the second emission gray level, y is the actual display brightness corresponding to the display pixel, G is the maximum actually displayable brightness corresponding to the light-emitting pixel, x1, x2, x3, and x4 are respectively the actual maximum brightness of the light-emitting pixels corresponding to the display pixel, where the subscripts 1-4 are respectively the light-emitting pixel numbers of the light-emitting pixels; the sum of the actual maximum brightnesses of all the light-emitting pixels in the first light-emitting pixel group is x1 + x3 (that is, the first sum value), and the brightness sum value of the first light-emitting pixel group is The brightness sum value of the first light-emitting pixel group is actually the ratio of the sum of the actual maximum brightnesses of all the light-emitting pixels in the first light-emitting pixel group to the number of light-emitting pixels corresponding to the display pixel, 4yG is the first product, (4y - x1 - x3) is the difference value, (4y - x1 - x3)G is the second product, and x2 + x4 is the second sum value.

[0059] For example, when a display pixel corresponds to four light-emitting pixels, the maximum displayable gray levels of the four light-emitting pixels 1, 2, 3, and 4 are all 255, and the actual maximum brightnesses corresponding to the four light-emitting pixels 1, 2, 3, and 4 are 100, 85, 90, and 80 respectively. When the actual display brightness corresponding to the display pixel is 60, the first emission gray level of the first pixel group (including the light-emitting pixels 1 and 3) can be calculated as 255, and the second emission gray level of the second pixel group (including the light-emitting pixels 2 and 4) is 77 according to Formula 1.

[0060] After obtaining the multiple emission gray levels corresponding to the display pixel, according to the light-emitting pixel number attributes of the multiple light-emitting pixels corresponding to the display pixel, the target emission gray level of each light-emitting pixel corresponding to the display pixel within its respective frame display period can be determined from the multiple emission gray levels corresponding to the display pixel.

[0061] S130. Control the multiple light-emitting pixels corresponding to each display pixel to emit light according to their respective target emission gray levels within their respective frame display periods, and control the pixel offset device to move so that the light emitted by each light-emitting pixel within its respective frame display period can be incident on the corresponding display pixel position.

[0062] While controlling the multiple light-emitting pixels corresponding to each display pixel to emit light according to their respective target emission gray levels within their respective frame display periods, the pixel offset device of the display panel is also controlled to offset so that the light emitted by each light-emitting pixel within its respective frame display period can be incident on the corresponding display pixel position, and the uniformity of the to-be-displayed image displayed on the display panel is better.

[0063] In this embodiment, according to the display gray level of each display pixel in the image to be displayed, a plurality of emission gray levels corresponding to the display pixel are generated. Then, according to the emission pixel serial number attributes of the plurality of emission pixels corresponding to the display pixel, the target emission gray level of each emission pixel corresponding to the display pixel within its respective frame display period is determined from the plurality of emission gray levels corresponding to the display pixel. Finally, the plurality of emission pixels corresponding to each display pixel are controlled to emit light according to their respective target emission gray levels within their respective frame display periods, and the pixel offset device is controlled to move so that the light emitted by each emission pixel within its respective frame display period can be incident on the corresponding display pixel position. By means of the pixel offset device, the display effect of the emission pixel within its respective frame display period is made to match the display effect of the image to be displayed, avoiding the occurrence of a poor display uniformity when only displaying the image to be displayed due to the poor uniformity of the display panel itself, thereby improving the display uniformity of the display panel and enhancing the display effect of the display panel.

[0064] Meanwhile, when there are defective pixels among the plurality of emission pixels corresponding to each display pixel, the other emission pixels corresponding to each display pixel can still emit light, avoiding the situation where when the emission pixel and the display pixel are in a one-to-one relationship, the defective emission pixel causes the display pixel corresponding to the emission pixel to be unable to display normally, thereby enhancing the display effect of the image to be displayed on the display panel.

[0065] 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:

[0066] S210. Obtain the display gray level of the display pixel in the image to be displayed.

[0067] S220. Generate a plurality of emission gray levels corresponding to the display pixel according to the display gray level of the display pixel.

[0068] Among them, the descriptions of S210 - S220 refer to the descriptions of S110 - S120 above and will not be elaborated here.

[0069] In addition, in this embodiment, the plurality of emission gray levels corresponding to the display pixel are multiple. For example, one emission pixel corresponds to one emission gray level.

[0070] In some embodiments, the plurality of emission gray levels corresponding to the display pixel include a first emission gray level and a second emission gray level; the determination process of the first emission gray level and the second emission gray level corresponding to the display pixel refers to the description of S120 above and will not be elaborated here.

[0071] S230. Determine the emission pixel serial number attribute of the m-th emission pixel corresponding to the display pixel.

[0072] Among them, m ∈ [1, N], N is the total number of light-emitting pixels corresponding to the display pixels, and the light-emitting pixel serial number attribute includes odd and even numbers.

[0073] S240. Determine the target light-emitting gray level of the m-th light-emitting pixel in the m-th frame display period corresponding to the image to be displayed from multiple light-emitting gray levels corresponding to the display pixels according to the light-emitting pixel serial number attribute.

[0074] Among them, if the light-emitting pixel serial number attribute is odd, determine that the target light-emitting gray level of the m-th light-emitting pixel in the m-th frame display period corresponding to the image to be displayed is the first light-emitting gray level; if the light-emitting pixel serial number attribute is even, determine that the target light-emitting gray level of the m-th light-emitting pixel in the m-th frame display period corresponding to the image to be displayed is the second light-emitting gray level.

[0075] It can be seen that among the multiple light-emitting pixels corresponding to the display pixels, the light-emitting pixels with odd light-emitting pixel serial number attributes output the first light-emitting gray level in their respective frame display periods, and the light-emitting pixels with even light-emitting pixel serial number attributes output the second light-emitting gray level in their respective frame display periods.

[0076] For example, each display pixel in the image to be displayed corresponds to 4 light-emitting pixels of the display panel. For any display pixel F, as Figure 4 shown, the display pixel F corresponds to light-emitting pixels f1, f2, f3, and f4. At this time, it can be determined that the frame display periods corresponding to the image to be displayed are also 4, and these 4 frame display periods have an order. Determine that the first light-emitting pixel f1 corresponding to the display pixel emits light according to the first light-emitting gray level in the first frame display period, and determine that the third light-emitting pixel f3 corresponding to the display pixel emits light according to the first light-emitting gray level in the third frame display period; determine that the second light-emitting pixel f2 corresponding to the display pixel emits light according to the second light-emitting gray level in the second frame display period, and determine that the fourth light-emitting pixel f4 corresponding to the display pixel emits light according to the second light-emitting gray level in the fourth frame display period.

[0077] For the display pixel F as Figure 4 shown, when the multiple light-emitting pixels corresponding to this display pixel F emit light, the brightness change is as Figure 5 shown. From Figure 5 it can be known that at this time, when displaying the display pixel F through the light-emitting pixels f1, f2, f3, and f4, the flicker frequency of the display pixel F is 60 Hz, and the critical flicker frequency that the human eye can feel is generally between 30 and 55 Hz, thereby eliminating the flicker sensation.

[0078] It is worth mentioning that when there are two emission gray levels corresponding to each display pixel constructed, including the first emission gray level and the second emission gray level, and the number of light-emitting pixels corresponding to each display pixel is n, if the refresh frequency of the display panel is n×M Hz, then the frame refresh frequency is M Hz. Among them, when n is an even number, the minimum flicker frequency of the display screen is (n / 2×M)Hz; when n is an odd number, the minimum flicker frequency of the display screen is [(n - 1) / 2×M]Hz.

[0079] S250. Cumulatively add 1 to m.

[0080] S260. Determine whether m exceeds N. If m does not exceed N, execute S230. If m exceeds N, determine to end the display of the image to be displayed and execute S270.

[0081] S270. Obtain the display gray level of the display pixels in the new image to be displayed. Then, return to execute the steps of S220.

[0082] In this embodiment, when there are two emission gray levels corresponding to the display pixels, the first emission gray level is output during the odd-frame display periods among the multiple frame display periods corresponding to the display pixels, and the second emission gray level is output during the even-frame display periods among the multiple frame display periods corresponding to the display pixels, so that the odd-numbered light-emitting pixels corresponding to the display pixel have the same gray level, and the even-numbered light-emitting pixels have the same gray level, realizing that the light-emitting pixels corresponding to the same display pixel display different gray levels, thereby increasing the frame flicker frequency, avoiding the situation of visible frame flicker caused by a low frame flicker frequency, and improving the user viewing experience.

[0083] Refer to Figure 6 , Figure 6 shows a block diagram of a display device proposed in an embodiment of the present application. The device 1000 includes:
