The purpose is to simplify the drawings and make the invention clear at a glance, rather than to indicate that the actual device is the same as the attached structure. Figure 1 The same is true, not set to the actual device limitations.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase at various times in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides a display device, which includes but is not limited to the following embodiments and combinations of the following embodiments.

[0022] In some embodiments, Figures 1 to 4As shown, the display device 100 includes a first display panel 101 and a second display panel 102, the interval between two adjacent sub-pixels Pi in the first display panel 101 is smaller than the interval between two adjacent sub-pixels Pi in the second display panel 102, the first display panel 101 includes a first display area A1 adjacent to the second display panel 102, and a second display area A2 located in the first display area A1 and away from the second display panel 102; the plurality of sub-pixels Pi in the first display panel 101 include a plurality of first-type sub-pixels HPi, a plurality of second-type sub-pixels MPi and a plurality of third-type sub-pixels LPi in a light-emitting state, and some of the sub-pixels Pi of the same color in the first display panel 101 are in a light-emitting state at the same grayscale value, wherein the first-type sub-pixels Among the first-category sub-pixels HPi, the second-category sub-pixels MPi and the third-category sub-pixels LPi, the brightness of the first-category sub-pixels HPi is greater than the brightness of the second-category sub-pixels MPi, and the brightness of the second-category sub-pixels MPi is greater than the brightness of the third-category sub-pixels LPi; wherein, when the multiple sub-pixels Pi in the first display panel 101 are in the luminous state corresponding to the same color and the same grayscale, the multiple sub-pixels Pi in the first display area A1 include at least multiple first-category sub-pixels HPi and multiple third-category sub-pixels LPi, and the total proportion of the first-category sub-pixels HPi and the third-category sub-pixels LPi in the first display area A1 is greater than the total proportion of the first-category sub-pixels HPi and the third-category sub-pixels LPi in the second display area A2.

[0023] The display device 100 of this embodiment may include a spliced ​​display panel formed by splicing a first display panel 101 and a second display panel 102 of different types, and the interval between two adjacent sub-pixels Pi in the first display panel 101 is smaller than the interval between two adjacent sub-pixels Pi in the second display panel 102, wherein the sub-pixel Pi refers to an active or passive light-emitting device set in the display device 100 through a process flow, and according to the difference in the luminescent material or the light-transmitting material, the sub-pixel Pi can eventually present a corresponding color when emitting light, that is, the arrangement density of the sub-pixel Pi is related to the process flow. For example, in this embodiment, the first display panel 101 with a larger arrangement density of sub-pixels Pi may be an LCD panel, and the second display panel 102 with a smaller arrangement density of sub-pixels Pi may be a direct display MLED panel.

[0024] It should be noted that the process flow causes the spacing of sub-pixels Pi within the surfaces of the first display panel 101 and the second display panel 102 to be different, which will appear as different resolutions of the two images when displaying the images, resulting in a large difference in the granularity of the images displayed by the two, resulting in poor image consistency at the joints of the display device 100.

[0025] Among them, the multiple sub-pixels Pi in the first display panel 101 of this embodiment include multiple first-type sub-pixels HPi, multiple second-type sub-pixels MPi and multiple third-type sub-pixels LPi in the luminous state corresponding to the same color and the same grayscale, and the multiple sub-pixels Pi include at least first-color sub-pixels R and second-color sub-pixels G of different colors. For color sub-pixels of the same color (for example, the first-color sub-pixel R or the second-color sub-pixel G), they can be defined as first-type sub-pixels HPi, second-type sub-pixels MPi or third-type sub-pixels LPi according to their luminous brightness in the luminous state. In the color sub-images, they are respectively first-type sub-pixels HPi, second-type sub-pixels MPi or third-type sub-pixels LPi, and the corresponding three brightnesses decrease sequentially.

[0026] It can be understood that in this embodiment, the first display panel 101 having a larger arrangement density of sub-pixels Pi is divided into a first display area A1 adjacent to the second display panel 102 and a second display area A2 located in the first display area A1 and away from the second display panel 102, and the first display area A1 is set to include a plurality of first-category sub-pixels HPi and a plurality of third-category sub-pixels LPi in a light-emitting state corresponding to the same color and the same grayscale, and compared with the second display area A2, the total proportion of the first-category sub-pixels HPi and the third-category sub-pixels LPi in the first display area A1 is higher. From the discussion of sub-pixels LPi, it can be seen that, compared with the area far away from the second display panel 102, the area adjacent to the second display panel 102 in the first display panel 101 has a higher proportion of the first sub-pixels HPi and the second sub-pixels MPi, which have the largest brightness difference under the luminous state corresponding to the same color and the same grayscale, so that the granularity of the picture is more obvious and closer to the picture of the second display panel 102 with greater granularity. Another area with a granularity between the second display panel 102 and the area of ​​the first display panel 101 far away from the second display panel 102 is set between the two, thereby improving the consistency of the picture of the display device 100 at the splicing point.

[0027] In some embodiments, Figures 1 to 4 As shown, when the multiple sub-pixels Pi in the first display panel 101 are in the light-emitting state, the multiple sub-pixels Pi in the second display area A2 are all sub-pixels MPi of the second type. That is, the brightness of the multiple sub-pixels Pi in the second display area A2 in the light-emitting state is medium, and the brightness of the light emitted by sub-pixels of different colors at the same grayscale value is the corresponding medium brightness, so that the display image of the second display area A2 is highly uniform.

[0028] Therefore, this embodiment can improve the consistency of the images of the display device 100 at the joints while reducing the graininess of the second display area A2 and improving the overall image quality of the first display panel 101 .

[0029] In some embodiments, Figures 1 to 4 As shown, in the light-emitting state, the plurality of sub-pixels Pi in the first display panel 101, the plurality of sub-pixels Pi in the first display area A1 are arranged into a plurality of repeating units 20, and the repeating units 20 at least include the first type of sub-pixels HPi and the third type of sub-pixels LPi. That is, in the light-emitting state corresponding to the same color and the same grayscale, the first display area A1 of this embodiment can divide the plurality of sub-pixels Pi into at least the first type of sub-pixels HPi and the third type of sub-pixels LPi according to the light-emitting brightness, and the plurality of sub-pixels Pi in the light-emitting state are arranged regularly to form a plurality of repeating units 20, and the light-emitting brightness of the plurality of sub-pixels Pi in each repeating unit 20 are arranged in the same arrangement mode (including quantity and position); further, each repeating unit 20 at least includes the first type of sub-pixels HPi and the third type of sub-pixels LPi, so that the first type of sub-pixels HPi and the third type of sub-pixels LPi with large differences in light-emitting brightness can be evenly distributed in the first display area A1 according to the same relative position relationship.

[0030] Therefore, this embodiment further improves the granularity of the display image of the first display area A1 to improve the consistency of the image at the joint of the display device 100, and also improves the uniformity of the display image of the first display area A1.

[0031] In some embodiments, Figures 1 to 4 As shown, the plurality of sub-pixels Pi in the first display panel 101 are arranged into a plurality of pixel units 30, and the pixel units 30 at least include a plurality of color sub-pixels of different colors (i.e., the first color sub-pixel R and the second color sub-pixel G mentioned above); wherein, in the light-emitting state, the plurality of sub-pixels Pi in the first display panel 101 have the same number and the same arrangement in different repeating units 20. The accompanying drawings take the example that the pixel unit 30 at least includes the first color sub-pixel R, the second color sub-pixel G, and the third color sub-pixel B of different colors, and the corresponding display colors of the three can be red, green, and blue, respectively.

[0032] It can be understood that the arrangement manner (including quantity and position) of the multiple color sub-pixels of different colors in each pixel unit 30 is the same, and the number and arrangement manner of the pixel units 30 contained in each repeating unit 20 in the present embodiment are the same, so that not only the arrangement manner of the multiple color sub-pixels of different colors in different repeating units 20 is the same, but also the arrangement manner of the first type of sub-pixels HPi and the third type of sub-pixels LPi with different luminous degrees is the same. Of course, when the first display area A1 also includes the second type of sub-pixels MPi when it is luminous, it can be considered that the arrangement manner of the first type of sub-pixels HPi, the second type of sub-pixels MPi and the third type of sub-pixels LPi in different repeating units 20 is also the same. It can be seen that the color distribution in different repeating units 20 is the same, and the brightness distribution at the same grayscale value is also the same, which further improves the uniformity of the display screen of the first display area A1.

[0033] In some embodiments, Figures 1 to 4 As shown, the plurality of pixel units 30 are arranged in an array, and the plurality of color sub-pixels of different colors in the pixel units 30 (for example, including a first color sub-pixel R, a second color sub-pixel G and a third color sub-pixel B) are arranged in an array; wherein, when the plurality of sub-pixels Pi in the first display panel 101 are in a light-emitting state, in the row direction D1 and / or the column direction D2, the arrangement manner of the first type of sub-pixels HPi and the third type of sub-pixels LPi in the first display area A1 are the same.

[0034] Specifically, multiple pixel units 30 are arranged in an array, and multiple color sub-pixels of different colors are also arranged in an array. For example, when the multiple color sub-pixels of different colors include a first color sub-pixel R, a second color sub-pixel G, and a third color sub-pixel B, the three can be arranged along the row direction D1 or the column direction D2. The accompanying drawings only take the latter as an example.

[0035] Specifically, if the first type of sub-pixels HPi and the third type of sub-pixels LPi are arranged in the same manner in the row direction D1, it means that a plurality of cycle units are repeatedly arranged in the row direction D1, and the changing rules between multiple consecutive columns of sub-pixels in different cycle units are the same. Similarly, if the first type of sub-pixels HPi and the third type of sub-pixels LPi are arranged in the same manner in the column direction D2, it means that a plurality of cycle units are repeatedly arranged in the column direction D2, and the changing rules between multiple consecutive rows of sub-pixels in different cycle units are the same.

[0036] It can be understood that this embodiment is based on the array arrangement of multiple pixel units 30 and multiple color sub-pixels of different colors in each of them, so that the first type of sub-pixels HPi and the third type of sub-pixels LPi of the same color and with the largest luminous difference at the same grayscale value in the first display area A1 are arranged in a regular pattern in the row direction D1 and / or the column direction D2, thereby improving the uniformity of the display image of the first display area A1 in the row direction D1 and / or the column direction D2, thereby improving the consistency of the overall image.

[0037] In some embodiments, Figures 1 to 4 As shown, when the multiple sub-pixels Pi in the first display panel 101 are in the light-emitting state, the multiple sub-pixels Pi in the odd columns or even columns in the first display area A1 are all the first-type sub-pixels HPi or the third-type sub-pixels LPi; the first-type sub-pixels HPi and the third-type sub-pixels LPi in the even columns or the odd columns are arranged alternately.

[0038] Specifically, in the present embodiment, the first display area A1 is in the light-emitting state and there are the following four situations:

[0039] Case 1: the multiple sub-pixels Pi in the odd-numbered columns are all first-type sub-pixels HPi, and the multiple sub-pixels Pi in the even-numbered columns are arranged alternately according to the first-type sub-pixels HPi and the third-type sub-pixels LPi;

[0040] Case 2: the plurality of sub-pixels Pi in odd-numbered columns are all third-type sub-pixels LPi, and the plurality of sub-pixels Pi in even-numbered columns are arranged alternately according to first-type sub-pixels HPi and third-type sub-pixels LPi;

[0041] Case 3: the multiple sub-pixels Pi in the even-numbered columns are all first-type sub-pixels HPi, and the multiple sub-pixels Pi in the odd-numbered columns are arranged alternately according to the first-type sub-pixels HPi and the third-type sub-pixels LPi;

[0042] In case 4, the multiple sub-pixels Pi in the even-numbered columns are all the third-type sub-pixels LPi, and the multiple sub-pixels Pi in the odd-numbered columns are arranged alternately according to the first-type sub-pixels HPi and the third-type sub-pixels LPi.

[0043] Among them, the first color sub-pixel R, the second color sub-pixel G and the third color sub-pixel B are arranged along the column direction D2, and taking the above "Case 4" as an example, it can be considered that when the first display area A1 is emitting light, the multiple sub-pixels Pi in each of the 1st, 3rd, 5th, 7th, 9th and 11th columns are arranged in an alternating manner according to the first type of sub-pixels HPi and the third type of sub-pixels LPi, and the multiple sub-pixels Pi in each of the 2nd, 4th, 6th, 8th, 10th and 12 columns are all the third type of sub-pixels LPi with lower brightness.

[0044] like Figure 3 and Figure 4As shown, although the multiple sub-pixels Pi in the odd columns are divided according to the luminous brightness, the smallest circulation unit is the adjacent first-category sub-pixel HPi and third-category sub-pixel LPi, but the smallest circulation unit is a complete pixel unit 30 when divided according to the luminous color. Therefore, taking into account both the luminous brightness and color, the smallest circulation unit of the multiple sub-pixels Pi in the odd columns is two consecutive pixel units 30. At the same time, considering that the multiple sub-pixels Pi in the even columns are all third-category sub-pixels LPi, the above-mentioned "repeating unit 20" should be two consecutive pixel units 30 and two pixel units 30 located in the corresponding 6 rows in a column adjacent to it, that is, the "repeating unit 20" includes 4 pixel units 30 arranged in a "2×2" pattern.

[0045] Furthermore, if, among the multiple sub-pixels Pi in the odd-numbered columns in "Case 4", the sub-pixels Pi in the odd-numbered rows are the first-type sub-pixels HPi with higher brightness, and the sub-pixels Pi in the even-numbered rows are the third-type sub-pixels LPi with lower brightness, then the pixel units 30 in the first display area A1 can be divided into the following three cases according to the arrangement of the first-type sub-pixels HPi and the third-type sub-pixels LPi therein:

[0046]

[0047] Among them, Image(i,j) represents the pixel unit 30 of the i-th row and j-th column, (H,L,H) represents the first color sub-pixel R, the second color sub-pixel G and the third color sub-pixel B in the pixel unit 30 are respectively the first type sub-pixel HPi, the third type sub-pixel LPi and the first type sub-pixel HPi, and (L,H,L) represents the first color sub-pixel R, the second color sub-pixel G and the third color sub-pixel B in the pixel unit 30 are respectively the third type sub-pixel LPi, the first type sub-pixel HPi and the third type sub-pixel LPi.

[0048] Among them, “…” indicates that the arrangement of the first type of sub-pixels HPi and the third type of sub-pixels LPi inside the pixel unit 30 corresponds to the row number i and column number j of the pixel unit 30; “%” indicates modulo, and “∧” indicates AND.

[0049] That is, the above equation relationship means the following;

[0050] (1) “j%2≠0∧i%2≠0”, that is, the first color sub-pixel R, the second color sub-pixel G and the third color sub-pixel B in the pixel unit 30 of odd columns and odd rows are respectively the first type sub-pixel HPi, the third type sub-pixel LPi and the first type sub-pixel HPi, that is, the brightness of the second color sub-pixel G located in the middle is lower than that of the other two;

[0051] (2) “j%2≠0∧i%2=0”, that is, in the pixel unit 30 with odd columns and even rows, the first color sub-pixel R, the second color sub-pixel G and the third color sub-pixel B inside thereof are respectively the third type sub-pixel LPi, the first type sub-pixel HPi and the third type sub-pixel LPi, that is, the brightness of the second color sub-pixel G located in the middle is higher than that of the other two;

[0052] (3) "j%2=0", that is, the first color sub-pixel R, the second color sub-pixel G and the third color sub-pixel B in the pixel units 30 of the even columns are all the third type of sub-pixels LPi, that is, the brightness of the light emitted by the pixel units 30 of the even columns is relatively low.

[0053] In some embodiments, Figures 1 to 4 As shown, when the plurality of sub-pixels Pi in the first display panel 101 are in the light-emitting state, the sum of the brightness of the plurality of sub-pixels Pi in different repeating units 20 in the first display area A1 is the same.

[0054] Combined with the above discussion, it can be known that in the light-emitting state corresponding to the same color and the same grayscale, the repeating unit 20 at least includes a first-type sub-pixel HPi with higher brightness and a third-type sub-pixel LPi with lower brightness, that is, the two have a large brightness difference. Based on this, the present embodiment sets the sum of the brightness of multiple sub-pixels Pi in different repeating units 20 to be the same, which can be understood as corresponding to the light-emitting state of the same color and the same grayscale, for two repeating units 20, if the brightness of the first-type sub-pixel HPi in one is higher, the brightness of the third-type sub-pixel LPi of the other can be set to be lower, and the brightness of the first-type sub-pixel HPi in the other can be lower, and the brightness of the third-type sub-pixel LPi can be higher, so as to balance the sum of the brightness of the first-type sub-pixel HPi and the corresponding third-type sub-pixel LPi when emitting light.

[0055] It can be understood that when the repeating unit 20 also includes a second type of sub-pixel MPi with a centered brightness in the light-emitting state, the brightness of the second type of sub-pixels MPi of different repeating units 20 can be set to be the same or different, and the number of each of the three types of sub-pixels in different repeating units 20 can also be set to be the same or different. In either case, the present embodiment sets the sum of the brightness of multiple sub-pixels Pi in different repeating units 20 in the light-emitting state to be the same, so that the brightness of different areas in the first display area A1 is close to consistent, thereby improving the consistency of the brightness of the first display area A1.

[0056] In some embodiments, Figures 1 to 4As shown, when some sub-pixels Pi (multiple first-color sub-pixels R, multiple second-color sub-pixels G or multiple third-color sub-pixels B) of the same color in the first display panel 101 are in the luminous state at the same grayscale value, the brightness difference between the first-type sub-pixels HPi and the corresponding third-type sub-pixels LPi is larger among the multiple sub-pixels Pi close to the second display panel 102 than the multiple sub-pixels Pi far away from the second display panel 102.

[0057] It can be understood that, corresponding to the light-emitting state of the same color and the same grayscale, the difference in brightness between the first-category sub-pixel HPi and the corresponding third-category sub-pixel LPi in the area closer to the second display panel 102 in the first display area A1 in this embodiment is larger, that is, the brightness of the first-category sub-pixel HPi can be set larger in the area closer to the second display panel 102 than in the area farther away from the second display panel 102, and / or the brightness of the corresponding third-category sub-pixel LPi can be set smaller. Therefore, the granularity of the display image in the light-emitting state in the first display area A1 along the direction pointing to the second display panel 102 is more obvious, and the degree of granularity closer to the second display panel 102 can further improve the consistency of the image at the splicing point of the display device 100.

[0058] The present invention provides a display method for a display device, which can be applied to, including but not limited to, the display device discussed above. The display method for the display device includes but is not limited to the following embodiments and combinations of the following embodiments.

[0059] In some embodiments, Figure 5 As shown, the display method includes but is not limited to the following steps and a combination of the following steps:

[0060] S1, obtaining a plurality of position information and a plurality of grayscale information corresponding to a plurality of sub-pixels in the first display panel;

[0061] For ease of description, the display method is shown as Figures 1 to 4 The arrangement of the luminous color and brightness of the sub-pixels Pi in the figure is discussed.

[0062] Among them, Figure 6 As shown, the original image can be obtained and analyzed, firstly, the row number i, column number j of the pixel unit 30 to which each sub-pixel Pi belongs and the color of the sub-pixel Pi are obtained, so as to determine the position information of the sub-pixel Pi. Of course, this premise is that the arrangement of multiple sub-pixels of different colors in the pixel unit 30 needs to be obtained. Among them, the grayscale information can be the original grayscale value gray of the sub-pixel Pi.

[0063] S2, determining a brightness type of a corresponding sub-pixel according to each of the position information, the brightness type being used to characterize whether the corresponding sub-pixel is a first-type sub-pixel, a second-type sub-pixel, or a third-type sub-pixel in a light-emitting state, wherein the plurality of sub-pixels in the first display panel are in a light-emitting state, the plurality of sub-pixels in the first display area at least include a plurality of the first-type sub-pixels and a plurality of the third-type sub-pixels, and the total proportion of the first-type sub-pixels and the third-type sub-pixels in the first display area is greater than the total proportion of the first-type sub-pixels and the third-type sub-pixels in the second display area;

[0064] In combination with the above discussion, it can be known that the brightness type of the plurality of sub-pixels Pi in the first display panel 101 in the light-emitting state, that is, whether it is the first type of sub-pixel HPi (for example, corresponding to the brightness type H), the second type of sub-pixel MPi or the third type of sub-pixel LPi (for example, corresponding to the brightness type L) is related to its position, so according to the position information of each sub-pixel Pi, it can be determined which type of sub-pixel it is in the light-emitting state. And according to the above discussion, when any picture is displayed, the plurality of sub-pixels Pi have been defined as the first type of sub-pixel HPi, the second type of sub-pixel MPi or the third type of sub-pixel LPi by their positions, and the plurality of sub-pixels Pi in the first display area A1 at least include a plurality of first type of sub-pixels HPi and a plurality of third type of sub-pixels LPi, and the total proportion of the first type of sub-pixels HPi and the third type of sub-pixels LPi in the first display area A1 is greater than the total proportion of the first type of sub-pixels HPi and the third type of sub-pixels LPi in the second display area A2, so as to improve the consistency of the picture at the splicing part of the display device 100.

[0065] S3, determining corresponding compensation information according to the brightness type and the grayscale information of each sub-pixel;

[0066] Combined with the above discussion on the three types of brightness sub-pixels, it can be seen that in the light-emitting state corresponding to the same color and the same grayscale, the brightness of the first type of sub-pixel HPi, the second type of sub-pixel MPi or the third type of sub-pixel LPi decreases in sequence. Specifically, for the same color sub-pixel Pi, in the same grayscale, different compensation information can be set to perform different degrees of brightness compensation, thereby achieving different brightness in the light-emitting state.

[0067] Specific, combined Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, step S3 may include but is not limited to the following steps and a combination of the following steps:

[0068] S31, determining whether the location information is location binding point information;

[0069] Among them, the position binding point information may include multiple position binding points, and the position binding point information may be taken from the value range of the column number j of the corresponding pixel unit 30 in the position information. For example, part of the column number may be selected as multiple position binding points, for example, it may include 5 position binding points x1 to x5 corresponding to the 5 interval columns. Furthermore, the spacing between each adjacent 5 interval columns may be equal.

[0070] If the location information is the location binding point information, execute:

[0071] S32, determining the corresponding compensation information according to the corresponding brightness type and the corresponding grayscale information;

[0072] like Figure 6 and Figure 7 As shown, if the column number j of the pixel unit 30 in the position information is one of multiple position binding points (for example, x1 to x5), the compensation table corresponding to the color of the sub-pixel Pi can be obtained first, and then the compensation information corresponding to the corresponding position binding point in the compensation table under the corresponding original grayscale value gray and the corresponding brightness type (brightness type H or brightness type L) can be obtained as the final compensation information.

[0073] If the location information is not the location binding point information, execute:

[0074] S33, obtaining information of two location binding points adjacent to the location information;

[0075] S34, determining the corresponding compensation information according to the two grayscale information corresponding to the two position binding point information under the brightness type;

[0076] like Figure 6 and Figure 7 As shown, for example, the column number j of the pixel unit 30 in the position information is between adjacent xn and xn+1 in x1 to x5, and n is a positive integer greater than 0 and less than 5. Then, after obtaining the compensation table corresponding to the color of the sub-pixel Pi, the two compensation information corresponding to the above-mentioned two position binding points xn and xn+1 under the corresponding original grayscale value gray and the corresponding brightness type (brightness type H or brightness type L) can be obtained.

[0077] Furthermore, the distance weight of the column number j of the pixel unit 30 in the position information between the adjacent xn and xn+1 can be calculated by the following linear difference method:

[0078] Coeff a =(jx n ) / (x m+1 -x n )

[0079] Furthermore, the distance weight and the above two compensation information can be calculated by a corresponding weight ratio to determine the final compensation information of the location binding point information. Figure 7 The two compensation information corresponding to the adjacent xn and xn+1 are data a and data b , then the final compensation information of column number j is:

[0080] data e =data a +coeff a ×(data b -data a )

[0081] Specific, combined Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, step S3 may also include but is not limited to the following steps and a combination of the following steps:

[0082] S35, determining whether the grayscale information is grayscale binding point information;

[0083] If the grayscale information is the grayscale binding point information, execute:

[0084] Similarly, the grayscale binding point information may include multiple grayscale binding points, and the grayscale binding point information may be taken from the value range of the original grayscale value gray in the grayscale information. For example, the values ​​of part of the value range of the original grayscale value gray may be selected as multiple grayscale binding points, for example, it may include 5 grayscale binding points gray1 to gray5 corresponding to the intervals. Furthermore, the spacing between each adjacent 5 grayscale binding points may be equal.

[0085] S36, determining the corresponding compensation information according to the corresponding brightness type and the corresponding position information;

[0086] like Figure 6 and Figure 7 As shown, if the original grayscale value gray of the sub-pixel Pi is one of a plurality of grayscale binding points (for example, gray1 to gray5), the compensation table corresponding to the color of the sub-pixel Pi can be obtained first, and then the compensation information corresponding to the corresponding grayscale binding point in the compensation table under the corresponding position information (for example, column number j) and the corresponding brightness type (brightness type H or brightness type L) can be obtained as the final compensation information.

[0087] If the grayscale information is not the grayscale position information, executing:

[0088] S37, obtaining two grayscale position information adjacent to the grayscale information;

[0089] S38, determining the corresponding compensation information according to the two position information corresponding to the two grayscale position information under the brightness type;

[0090] like Figure 6 and Figure 7 As shown, for example, the original grayscale value gray of the sub-pixel Pi is between the adjacent grayscale binding points grayn and grayn+1 in gray1 to gray5, and n is a positive integer greater than 0 and less than 5 (different from the physical meaning of n in the above characterization of xn and xn+1). After obtaining the compensation table corresponding to the color of the sub-pixel Pi, two compensation information corresponding to the above two grayscale binding points grayn and grayn+1 under the corresponding column number j and the corresponding brightness type (brightness type H or brightness type L) can be obtained;

[0091] Furthermore, the grayscale weight of the original grayscale value gray between adjacent grayscale binding points grayn and grayn+1 may be calculated by the following linear difference method:

[0092] Coeff b =(gray-gray n ) / (gray n+1 -gray n )

[0093] Further, here, based on the simultaneous existence of the above distance weight and grayscale weight, as an example, Figure 7 As shown, the process of calculating compensation information may include:

[0094] First, determine the adjacent grayscale binding points grayn and grayn+1 between which the original grayscale value gray of the sub-pixel Pi lies, and determine the position information of the sub-pixel Pi and the corresponding adjacent position binding points xn and xn+1 in the position binding point information, so as to obtain the compensation information data corresponding to grayn and xn from the corresponding color compensation table. a , grayn and compensation information data corresponding to xn+1 b , grayn+1 and xn corresponding compensation information data c , grayn+1 and xn+1 corresponding compensation information data d , the specific determination method can refer to the relevant discussion above;

[0095] Then, the compensation information data corresponding to a column of sub-pixels Pi and the grayscale binding point grayn between xn and xn+1 is determined by linear interpolation. e , and determine the compensation information data corresponding to a column of sub-pixels Pi between xn and xn+1 and the grayscale binding point grayn+1f , the specific formula is as follows:

[0096] data e = data a +coeff a ×(data b -data a )

[0097] data f =data c +coeff a ×(data d -data c )

[0098] Then, the final compensation information is determined by the weight relationship between the original grayscale value gary and the corresponding adjacent grayscale binding points grayn and grayn+1. The specific formula is as follows:

[0099] data g =data e +coeff b ×(data f -data e )

[0100] S4, driving the corresponding sub-pixel to emit light according to the compensation information;

[0101] Specifically, the data voltage of the sub-pixel Pi corresponding to the original grayscale value gray under the light-emitting type can be determined according to the compensation information, and the corresponding sub-pixel can be driven to emit light according to the data voltage.
