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 limit.

[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection 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 does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, 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, as Figures 1 to 4As shown, the display device 100 includes a first display panel 101 and a second display panel 102 that are spliced ​​together. 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 on a side of the first display area A1 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. In a light-emitting state of a portion of sub-pixels Pi with the same color in the first display panel 101 at the same grayscale value, the first 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 together 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. The sub-pixel Pi refers to an active or passive light-emitting device set in the display device 100 through a process flow. Depending on the difference in the luminescent material or the light-transmitting material, the sub-pixel Pi can ultimately 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 the 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 image, resulting in a large difference in the granularity of the displayed images, resulting in poor image consistency at the splicing point 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, first-color sub-pixels R or second-color sub-pixels 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-pixels, 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 in sequence.

[0026] It can be understood that in this embodiment, the first display panel 101 having a higher 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-type sub-pixels HPi and a plurality of third-type 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-type sub-pixels HPi and the third-type sub-pixels LPi in the first display area A1 is higher. From the discussion of the sub-pixel LPi, it can be seen that the area adjacent to the second display panel 102 in the first display panel 101 has a higher proportion of the first type of sub-pixels HPi and the second type of sub-pixels MPi, which have the largest brightness difference under the luminous state corresponding to the same color and the same grayscale, compared with the area far away from the second display panel 102. This makes the graininess of the picture more obvious and closer to the picture of the second display panel 102 with greater graininess. Another area with a graininess 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, as 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 of the second type MPi. That is, the brightness of the multiple sub-pixels Pi in the second display area A2 when in the light-emitting state is medium, and the brightness of sub-pixels of different colors at the same grayscale value is the corresponding medium brightness, resulting in a high uniformity of the display image in the second display area A2.

[0028] Therefore, this embodiment can improve the consistency of the images at the joints of the display device 100 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, as 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 first display area A1 are arranged into a plurality of repeating units 20, and the repeating units 20 include at least the first-type sub-pixels HPi and the third-type sub-pixels LPi. That is, in the first display area A1 of this embodiment, when the multiple sub-pixels Pi are in the light-emitting state corresponding to the same color and the same grayscale, the multiple sub-pixels Pi can be divided into at least the first-type sub-pixels HPi and the third-type sub-pixels LPi according to the luminous brightness. The multiple sub-pixels Pi in the light-emitting state are arranged in a regular pattern to form a plurality of repeating units 20, and the luminous brightness of the multiple sub-pixels Pi in each repeating unit 20 is arranged in the same arrangement (including number and position). Furthermore, each repeating unit 20 includes at least the first-type sub-pixels HPi and the third-type sub-pixels LPi, so that the first-type sub-pixels HPi and the third-type sub-pixels LPi with relatively large differences in luminous 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 splicing portion of the display device 100 and also improves the uniformity of the display image of the first display area A1.

[0031] In some embodiments, as Figures 1 to 4 As shown, the multiple sub-pixels Pi in the first display panel 101 are arranged into a plurality of pixel units 30. Each pixel unit 30 includes at least a plurality of color sub-pixels of different colors (i.e., the first color sub-pixel R and the second color sub-pixel G described above). When the multiple sub-pixels Pi in the first display panel 101 are in the luminous state, the number and arrangement of the pixel units 30 in different repeating units 20 are the same. The accompanying drawings illustrate an example in which a pixel unit 30 includes at least a first color sub-pixel R, a second color sub-pixel G, and a third color sub-pixel B of different colors. The colors displayed by the three colors may be red, green, and blue, respectively.

[0032] It can be understood that the arrangement (including quantity and position) of the multiple color sub-pixels of different colors in each pixel unit 30 is the same, and each repeating unit 20 in this embodiment contains the same number of pixel units 30 and the same arrangement, so that not only the arrangement of the multiple color sub-pixels of different colors in different repeating units 20 is the same, but also the arrangement of the first type of sub-pixels HPi and the third type of sub-pixels LPi with different luminous levels is the same. Of course, when the first display area A1 is luminous and also includes the second type of sub-pixels MPi, it can be considered that the arrangement 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 image of the first display area A1.

[0033] In some embodiments, as Figures 1 to 4 As shown, the plurality of pixel units 30 are arranged in an array, and the plurality of color sub-pixels (for example, including a first color sub-pixel R, a second color sub-pixel G, and a third color sub-pixel B) of different colors in the pixel unit 30 are arranged in an array; wherein, the plurality of sub-pixels Pi in the first display panel 101 are in a light-emitting state, and 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 is the same.

[0034] Specifically, multiple pixel units 30 are arranged in an array, and multiple color sub-pixels of different colors therein 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 figure only uses the latter as an example.

[0035] Specifically, if the first-type sub-pixels HPi and the third-type sub-pixels LPi are arranged in the same manner in the row direction D1, it means that multiple cyclic units are repeatedly arranged in the row direction D1, and the change rules between multiple consecutive columns of sub-pixels in different cyclic units are the same. Similarly, if the first-type sub-pixels HPi and the third-type sub-pixels LPi are arranged in the same manner in the column direction D2, it means that multiple cyclic units are repeatedly arranged in the column direction D2, and the change rules between multiple consecutive rows of sub-pixels in different cyclic 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, as 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 within 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 this embodiment, when the first display area A1 is in the light-emitting state, there are the following four situations:

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

[0040] Case 2: the multiple sub-pixels Pi in the odd-numbered columns are all third-type sub-pixels LPi, 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;

[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 third-type sub-pixels LPi, and the multiple sub-pixels Pi in the odd-numbered columns are alternately arranged 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 cycle unit is the adjacent first-type sub-pixel HPi and third-type sub-pixel LPi, but according to the luminous color, the smallest cycle unit is a complete pixel unit 30. Therefore, considering both the luminous brightness and color, the smallest cycle 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-type sub-pixels LPi, the above-mentioned "repeating unit 20" should be two consecutive pixel units 30 and two pixel units 30 in the corresponding 6 rows in the adjacent column, that is, the "repeating unit 20" includes "2 2" arranged in four pixel units 30.

[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 of sub-pixels HPi with higher brightness, and the sub-pixels Pi in the even-numbered rows are the third type of 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 of sub-pixels HPi and the third type of sub-pixels LPi therein:

[0046]

[0047] in, represents the pixel unit 30 at the i-th row and j-th column, Indicates that 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, It indicates that 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 the third type sub-pixel LPi, the first type sub-pixel HPi, and the third type sub-pixel LPi respectively.

[0048] Wherein, “…” 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 the column number j of the pixel unit 30; " means remainder," " means mutuality.

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

[0050] (1) " ”, that is, the pixel units 30 in odd columns and odd rows, the first color sub-pixel R, the second color sub-pixel G, and the third color sub-pixel B therein 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 in the middle is lower than that of the other two;

[0051] (2) “ ”, that is, the pixel units 30 in odd columns and even rows, the first color sub-pixels R, second color sub-pixels G, and third color sub-pixels B therein 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 in the middle is higher than that of the other two;

[0052] (3) " ”, 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 in 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 in the even columns is relatively low.

[0053] In some embodiments, as 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] As discussed above, corresponding to the same color and grayscale lighting state, the repeating unit 20 includes at least a first-type sub-pixel HPi with higher brightness and a third-type sub-pixel LPi with lower brightness, i.e., there is a significant brightness difference between the two types. Based on this, in this embodiment, the sum of the brightness of the multiple sub-pixels Pi in different repeating units 20 is set to be the same. This can be understood as follows: in the same color and grayscale lighting state, 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 in that repeating unit can be set to be lower, while the brightness of the first-type sub-pixel HPi in the other repeating unit 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-pixels HPi and the corresponding third-type sub-pixels LPi in the two repeating units.

[0055] It can be understood that when the repeating unit 20 also includes a second type of sub-pixels MPi with intermediate brightness in the luminous 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, this embodiment sets the sum of the brightness of multiple sub-pixels Pi in different repeating units 20 in the luminous 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, as Figures 1 to 4As shown, when some sub-pixels Pi (a plurality of first-color sub-pixels R, a plurality of second-color sub-pixels G, or a plurality of 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 plurality of sub-pixels Pi close to the second display panel 102 have a larger difference in brightness between the first-type sub-pixels HPi and the corresponding third-type sub-pixels LPi than the plurality of sub-pixels Pi far away from the second display panel 102.

[0057] It can be understood that, corresponding to the luminous state of the same color and the same grayscale, in the first display area A1 of this embodiment, the difference in brightness between the first type of sub-pixel HPi and the corresponding third type of sub-pixel LPi in the area closer to the second display panel 102 is greater, that is, the brightness of the first type of sub-pixel HPi can be set to be greater than that of the area farther away from the second display panel 102, and / or the brightness of the corresponding third type of sub-pixel LPi can be set to be smaller. Therefore, the graininess of the display image in the luminous state in the first display area A1 along the direction pointing to the second display panel 102 is more obvious, and the degree of graininess 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, 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, as 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 embodiment is discussed.

[0062] Among them, such as Figure 6 As shown, the original image can be acquired and analyzed by first acquiring the row number i and column number j of the pixel unit 30 to which each sub-pixel Pi belongs, as well as the color of the sub-pixel Pi, thereby determining the position information of the sub-pixel Pi. Of course, this is premised on acquiring the arrangement of multiple sub-pixels of different colors in the pixel unit 30. 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 based on each piece of position information, the brightness type being used to characterize whether the corresponding sub-pixel is a first-category sub-pixel, a second-category sub-pixel, or a third-category 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 include at least a plurality of the first-category sub-pixels and a plurality of the third-category sub-pixels, and the total proportion of the first-category sub-pixels and the third-category sub-pixels in the first display area is greater than the total proportion of the first-category sub-pixels and the third-category sub-pixels in the second display area;

[0064] As discussed above, the luminance type of the plurality of sub-pixels Pi in the first display panel 101 when in a light-emitting state, i.e., whether they are first-type sub-pixels HPi (e.g., corresponding to luminance type H), second-type sub-pixels MPi, or third-type sub-pixels LPi (e.g., corresponding to luminance type L), is related to their position. Therefore, the luminance type of each sub-pixel Pi can be determined based on its position information. Furthermore, as discussed above, when displaying any image, the plurality of sub-pixels Pi are defined as first-type sub-pixels HPi, second-type sub-pixels MPi, or third-type sub-pixels LPi based on their position.

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

[0084] Similarly, the grayscale binding point information can include multiple grayscale binding points, and the grayscale binding point information can 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 can be selected as multiple grayscale binding points. For example, it can include 5 grayscale binding points gray1 to gray5 corresponding to the intervals. Furthermore, the spacing between each adjacent 5 intervals of grayscale binding points can be equal.

[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, the number of columns j) and the corresponding brightness type (brightness type H or brightness type L) can be obtained as the final compensation information.

[0091] Furthermore, the original grayscale value gray at the adjacent grayscale binding point gray can be calculated by the following linear difference method: n 、gray n+1 Grayscale weights between:

[0092]

[0093] Furthermore, 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:
