[0030] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0031] As mentioned in the background technology, the existing spliced ​​display panels have the problem of poor display effect. The inventors found through research that the reason for this problem is that the pixel units of each spliced ​​screen in the spliced ​​display panel are evenly arranged. Under the premise of tolerances such as splicing manufacturing and screen size, it is impossible to ensure that the spacing of the pixel units at the splicing position is consistent with that at other positions of the splicing screen. After splicing into a large-size display panel, there is a difference between the displayed image at the splicing position and other areas, resulting in poor display effect of the display panel.

[0032] In order to solve the above technical problems, an embodiment of the present invention provides a display panel. Figure 1 is a schematic diagram of a display panel provided by an embodiment of the present invention, Figure 2 is a schematic diagram of another display panel provided by an embodiment of the present invention, Figure 3 yes Figure 1 The cross-sectional view of the panel along the section line AA is shown in FIG. Figure 1 and Figure 2 , the display panel includes:

[0033] At least two splicing screens 10, each splicing screen 10 includes a central area 11 and at least one splicing adjustment area 12, and each splicing adjustment area 12 is adjacent to at least one other splicing screen 10;

[0034] The splicing adjustment area 12 is adjacent to other splicing screens 10 along a first direction X, and a first spacing D1 of pixel units 20 in the splicing adjustment area 12 along the first direction X is smaller than a second spacing D2 of pixel units 20 in the central area 11 along the first direction X; and / or, the splicing adjustment area 12 is adjacent to other splicing screens 10 along a second direction Y, and a third spacing D3 of pixel units 20 in the splicing adjustment area 12 along the second direction Y is smaller than a fourth spacing D4 of pixel units 20 in the central area 11 along the second direction Y; wherein the first direction X and the second direction Y intersect with each other;

[0035] When the sizes of the splicing gaps between two adjacent splicing screens 10 are different, the positions of the turned-on pixel units 20 in the splicing adjustment areas 12 of the two adjacent splicing screens 10 are different.

[0036] It is understandable that, since the spacing between the pixel units 20 in the splicing adjustment area 12 is smaller than the spacing between the pixel units 20 in the central area 11, when at least two splicing screens 10 are spliced ​​together, the pixel units 20 at the corresponding positions in the splicing adjustment area 12 can be selected for display according to the size of the splicing seam, that is, the pixel units 20 at the corresponding positions are selected to be turned on, so that the spacing between the pixel units 20 at the edges of adjacent splicing screens 10 used for display after the splicing is completed is similar to or the same as the spacing between the pixel units 20 in the central area 11, thereby avoiding the large difference between the spacing between the pixel units 20 at the edges and the spacing between the pixel units 20 in the central area 11 due to the presence of the splicing seam, which affects the display and improves the display effect of the display panel. For example, refer to Figure 3 When the gap size GAP between two adjacent splicing screens is determined, the pixel units 20 turned on in the splicing adjustment area 12 can be determined according to the gap size GAP and the second spacing D2 of the pixel units 20 in the central area 11 along the first direction ( Figure 3 The pixel units 20 in the middle filling pattern are the pixel units 20 turned on in the splicing adjustment area 12), so that the pitch P2 of the pixel units 20 used for display at the splicing seam and the pitch P1 of the pixel units 20 used for display at the intersection of the central area 11 and the splicing adjustment area 12 are close to or the same as the second pitch D2.

[0037] It should be noted that when a splicing screen 10 is spliced ​​with another splicing screen 10, the splicing screen 10 includes a splicing adjustment area 12. When the splicing screen 10 is adjacent to the other splicing screen 10 along the first direction X, the first spacing D1 of the pixel units 20 in the splicing adjustment area 12 of the splicing screen 10 along the first direction X is smaller than the second spacing D2 of the pixel units 20 in the central area 11 along the first direction X ( Figure 1 ), or, when the splicing screen 10 is adjacent to another splicing screen 10 along the second direction Y, the third spacing D3 of the pixel units 20 in the splicing adjustment area 12 of the splicing screen 10 along the second direction Y is smaller than the fourth spacing D4 of the pixel units 20 in the central area 11 along the second direction Y (not shown in the figure).

[0038] When a splicing screen 10 is spliced ​​with two other splicing screens 10, and the two other splicing screens 10 are spliced ​​with two opposite sides of the current splicing screen 10, the current splicing screen includes two splicing adjustment areas 12, and the two splicing adjustment areas 12 are respectively adjacent to the two other splicing screens 10. For example, when the two other splicing screens 10 are respectively located on both sides of the current splicing screen along the first direction X (second direction Y), the first spacing D1 (third spacing D3) of the pixel units 20 in the two splicing adjustment areas 12 along the first direction X (second direction Y) is smaller than the second spacing D2 (fourth spacing D4) of the pixel units 20 in the central area 11 along the first direction X (second direction Y).

[0039] When a splicing screen 10 is spliced ​​with two other splicing screens 10, and the two other splicing screens 10 are spliced ​​with two adjacent sides of the current splicing screen 10, the current splicing screen 10 includes three splicing adjustment areas 12. For example, referring to Figure 2 The first splicing screen 101 is spliced ​​with the second splicing screen 102 and the third splicing screen 103, respectively. The first splicing screen 101 includes a first splicing adjustment area 121 adjacent only to the second splicing screen 102 along the first direction X, a third splicing adjustment area 123 adjacent only to the third splicing screen 103 along the second direction Y, and a second splicing adjustment area 122 adjacent to both the second splicing screen 102 and the third splicing screen 103. A first spacing D1 of pixel units 20 along the first direction X in the first splicing adjustment area 121 is smaller than a second spacing D2 of pixel units 20 along the first direction X in the central area 11. A third spacing D3 of pixel units 20 along the second direction Y in the third splicing adjustment area 123 is smaller than a fourth spacing D4 of pixel units 20 along the second direction Y in the central area 11. The first spacing D1 of the pixel units 20 in the second splicing adjustment area 122 along the first direction X is smaller than the second spacing D2 of the pixel units 20 in the central area 11 along the first direction X, and the third spacing D3 along the second direction Y is smaller than the fourth spacing D4 of the pixel units 20 in the central area 11 along the second direction Y. After the first splicing screen 101, the second splicing screen 102, and the third splicing screen 103 are spliced ​​together, the positions of the enabled pixel units 20 in the first splicing adjustment area 121 and the splicing adjustment area at the first splicing seam of the second splicing screen 102 can be determined based on the size of the first splicing seam between the first splicing screen 101 and the second splicing screen 102, so that the spacing of the pixel units 20 used for display at the first splicing seam along the first direction X is similar to that of the central area 11. The positions of the enabled pixel units 20 in the third splicing adjustment area 123 and the splicing adjustment area at the second splicing seam of the third splicing screen 103 can be determined based on the size of the second splicing seam between the first splicing screen 101 and the third splicing screen 103, so that the spacing of the pixel units 20 used for display at the second splicing seam along the second direction Y is close to that of the central area 11. Furthermore, the positions of the enabled pixel units 20 in the second splicing adjustment area 122 can be determined based on the size of the first splicing seam and the second splicing seam, ensuring that the spacing of the pixel units 20 used for display in the second splicing adjustment area 122 along the first direction X and along the second direction Y are close to that of the central area 11, thereby improving the display effect.

[0040] In addition, when a splicing screen 10 is spliced ​​with three or more splicing screens 10, it has three or more splicing adjustment areas. The specific positions of the splicing adjustment areas can be determined in combination with the above embodiments.

[0041] in addition, Figure 1 The exemplary display panel includes two spliced ​​screens 10. Figure 2The display panel is shown as including four spliced ​​screens by way of example, which is not a limitation of the present invention. In other embodiments, there may be multiple spliced ​​screens.

[0042] In addition, the pixel unit 20 is the smallest repeating unit of light emission in the display panel, and each pixel unit 20 may include at least three sub-pixels of different light emission colors. For example, each pixel unit may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

[0043] In an embodiment of the present invention, each splicing screen includes at least one splicing adjustment area. When the splicing adjustment area is adjacent to other splicing screens along a first direction, a first spacing of pixel units in the splicing adjustment area along the first direction is smaller than a second spacing of pixel units in the central area along the first direction; and / or, when the splicing adjustment area is adjacent to other splicing screens along a second direction, a third spacing of pixel units in the splicing adjustment area along the second direction is smaller than a fourth spacing of pixel units in the central area along the second direction. Since the spacing of pixel units in the splicing adjustment area is smaller than the spacing of pixel units in the central area, after at least two splicing screens are spliced ​​together, pixel units at corresponding positions in the splicing adjustment area can be selected for display based on the size of the splicing seam, so that the spacing between pixel units used for display at the edges of adjacent splicing screens after the splicing is completed is similar to or the same as the spacing between pixel units in the central area, thereby avoiding an excessive difference between the spacing of pixel units at the edge and the spacing of pixel units in the central area due to the presence of the splicing seam, which affects the display, thereby improving the display effect of the display panel.

[0044] Optional, reference Figure 2 , the display panel also includes:

[0045] The driving module 30 is used to drive the pixel units 20 at corresponding positions in the splicing adjustment area 12 to turn on according to the size of the splicing seam between two adjacent splicing screens 10 and the required spacing between the pixel units 20 .

[0046] Specifically, the driving module 30 can be a driving circuit board or a driving chip used to drive the splicing screen 10 to emit light. After the display panel is spliced, the size of each seam can be sent to the driving module. The driving module determines the position of the pixel unit 20 used to display the picture in the splicing adjustment area 12 according to the size of the seam and the required spacing, and drives the pixel unit 20 to turn on when displaying the picture.

[0047] Figure 4 is a schematic diagram of a spliced ​​screen provided by an embodiment of the present invention, Figure 5 This is a schematic diagram of another splicing screen provided by an embodiment of the present invention. Figure 4 and Figure 5Each splicing adjustment area 12 is also correspondingly provided with a transition area 13. Each transition area 13 is located between its corresponding splicing adjustment area 12 and the central area 11. Along the transition area 13 pointing in the direction of the splicing adjustment area 12 corresponding to the transition area 13, the spacing of the pixel units 20 in the transition area 13 gradually increases, and the spacing of the pixel units 20 in the transition area 13 is greater than the spacing of the pixel units 20 in the central area 11.

[0048] Specifically, refer to Figure 4 , Figure 4 The middle splicing screen has a splicing adjustment area 12 and a transition area 13. Along the direction of the transition area 13 pointing to the splicing adjustment area 12 (parallel to the first direction X), the spacing of the pixel units 20 in the transition area 13 gradually increases, that is, along the direction of the center of the splicing screen pointing to the seam, the spacing of the pixel units 20 in the transition area 13 gradually increases. Due to problems with the seam process, there may be large differences in the seam size. For example, there may be a problem of a large seam, resulting in a large spacing between the pixel units 20 used for display at the seam. By setting the transition area 13, the spacing of the pixel units 20 used for display gradually transitions from the central area 11 to the splicing adjustment area 12, avoiding sudden changes in spacing, further improving the display effect, and reducing the difficulty of the splicing process and the difficulty of the manufacturing process of the splicing adjustment area 12.

[0049] refer to Figure 5 , Figure 5 The central splicing screen has three splicing adjustment zones and three transition zones 13. The three splicing adjustment zones are sequentially arranged along a direction surrounding the central zone 11. The second splicing adjustment zone 122 is located between the first splicing adjustment zone 121 and the third splicing adjustment zone 123. The three transition zones 13 are sequentially arranged along a direction surrounding the central zone 11. The second transition zone 132 is located between the first transition zone 132 and the third transition zone 133. The first transition zone 131 is located between the central zone 11 and the first splicing adjustment zone 121, the second transition zone 132 is located between the central zone 11 and the second splicing adjustment zone 122, and the third transition zone 133 is located between the central zone 11 and the third splicing adjustment zone 123. The spacing of the pixel units 20 in the first transition zone 131 gradually increases along the direction from the first transition zone 131 to the first splicing adjustment zone 121 (parallel to the first direction X). The spacing of the pixel units 20 in the third transition zone 133 gradually increases along the direction from the third transition zone 133 to the third splicing adjustment zone 123 (parallel to the second direction Y). The spacing of the pixel units 20 in the second transition zone 132 gradually increases along the direction from the second transition zone 132 to the second splicing adjustment zone 122. It can be that the spacing of the pixel units 20 in the second transition zone 132 gradually increases along the direction from the second transition zone 132 to the second splicing adjustment zone 122, and the spacing of the pixel units 20 in the second transition zone 132 gradually increases along the direction from the second transition zone 132 to the first splicing adjustment zone 121.

[0050] Optionally, the driving module 30 is specifically used to drive the pixel units 20 at corresponding positions in the splicing adjustment area 12 to turn on according to the size of the splicing seam between two adjacent splicing screens 10 and the spacing of the pixel units in the transition area 13 along the direction of the transition area 13 pointing to the splicing adjustment area 12 corresponding to the transition area 13.

[0051] Specifically, Figure 6 is a cross-sectional view of another display panel provided by an embodiment of the present invention, referring to Figure 5 and Figure 6 , the spacing of the pixel units 20 in the transition area 13 gradually increases from D2+S to D2+(n-1)S and D2+nS along the direction pointing to the splicing adjustment area 12, where S is a positive number and n is a positive integer. The driving module 30 can select the pixel units 20 to be turned on in the splicing adjustment area 12 according to the size of the splicing gap GAP and the spacing of the pixel units 20 in the transition area 13, so that P1 and P2 smoothly transition with D2+nS, thereby achieving a better display effect at the edge. For example, the positions of the turned-on pixel units 20 can be made to satisfy P1=D2+(n+1)S, P2=D2+(n+2)S, or P1=D2+(n-1)S, P2=D2+(n-2)S, or P1=D2+nS, P2=D2+(n+1)S, or P1=D2+nS, P2=D2+(n-1)S.

[0052] Optionally, the spacing between pixel units 20 in the same splicing adjustment area 12 is equal. This arrangement reduces the difficulty of manufacturing the pixel units 20 in the splicing adjustment area 12, reduces the manufacturing cost, and reduces the computational difficulty of the subsequent driving module 30 in determining the position of the pixel unit 20 to be turned on.

[0053] Optional, continue to refer to Figure 2 The ratio of the first distance D1 to the second distance D2 includes 1 / 4-1 / 2, and the ratio of the third distance D3 to the fourth distance D4 includes 1 / 4-1 / 2.

[0054] Specifically, if the spacing between the pixel units 20 in the splicing adjustment area 12 is too small, the manufacturing difficulty of the pixel units 20 in the splicing adjustment area 12 is too great. If the spacing between the pixel units 20 in the splicing adjustment area 12 is too large, it is not conducive to adjusting the spacing of the pixel units 20 used for display at the edge. By setting the ratio of the first spacing D1 to the second spacing D2 to include 1 / 4-1 / 2, and the ratio of the third spacing D3 to the fourth spacing D4 to include 1 / 4-1 / 2, while reducing the manufacturing difficulty of the splicing adjustment area 12, it is ensured that by selecting the position of the pixel units 20 used for display in the splicing adjustment area 12, the spacing of the pixel units 20 used for display at the edge can be well adjusted, thereby improving the display effect. For example, the ratio of the first spacing D1 to the second spacing D2 can be 1 / 4, 1 / 3 or 1 / 2, and the ratio of the third spacing D3 to the fourth spacing D4 can be 1 / 4, 1 / 3 or 1 / 2, etc.

[0055] Optional, reference Figure 4 and Figure 5 , along the first direction X, the ratio of the spacing between the pixel units 20 in the transition area 13 to the spacing between the pixel units 20 in the central area 11 includes 6 / 5-3 / 2, and / or, along the second direction Y, the ratio of the spacing between the pixel units 20 in the transition area 13 to the spacing between the pixel units 20 in the central area 11 includes 6 / 5-3 / 2.

[0056] In particular, along the first direction X, the ratio of the spacing between the pixel units 20 in the transition region 13 to the spacing between the pixel units 20 in the central region 11 ranges from 6 / 5 to 3 / 2. Alternatively, along the first direction X, the spacing between the pixel units 20 in the transition region 11 and the spacing between the pixel units 20 in the central region 11 may gradually change from 6 / 5 to 3 / 2, or from a smaller value between 6 / 5 and 3 / 2 to a larger value between 6 / 5 and 3 / 2. Along the second direction Y, the ratio of the spacing between the pixel units 20 in the transition region 13 to the spacing between the pixel units 20 in the central region 11 ranges from 6 / 5 to 3 / 2. Alternatively, along the second direction Y, the spacing between the pixel units 20 in the transition region 13 and the spacing between the pixel units 20 in the central region 11 may gradually change from 6 / 5 to 3 / 2, or from a smaller value between 6 / 5 and 3 / 2 to a larger value between 6 / 5 and 3 / 2.

[0057] By setting the ratio of the spacing between the pixel units 20 in the transition area 13 and the spacing between the pixel units 20 in the central area 11 to include 6 / 5-3 / 2, the pixel spacing in the transition area 13 can meet the edge area pixel spacing corresponding to various stitching sizes, so that the transition area 13 plays a better transition role between the central area 11 and the stitching adjustment area 12, thereby improving the display effect.

[0058] This embodiment also provides a display device, Figure 7 is a schematic diagram of a display device provided in this embodiment, referring to Figure 7 , the display device 100 includes a display panel 200 according to any embodiment of the present invention.
