Detailed ways

As mentioned in the background technology, the splicing display panel in the related art has the problem of poor display effect. The applicant found through research that the reason for this problem is that the pixel units of the splicing screen in the splicing display panel are evenly arranged. Under the premise of tolerances such as manufacturing and screen size, it is impossible to guarantee that the pixel unit spacing at the splicing position is consistent with the pixel unit spacing at other positions on the splicing screen. difference, resulting in poor display effect of the display panel.

The embodiment of the present application provides a display panel. FIG. 1 is a schematic diagram of a display panel provided in the embodiment of the present application. FIG. 2 is a schematic diagram of another display panel provided in the embodiment of the present application. FIG. A schematic cross-sectional view of the display panel along the section line AA, referring to Figure 1 and Figure 2, the display panel includes:

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

The splicing adjustment area 12 being adjacent to at least one other splicing screen 10 includes at least one of the following situations:

The splicing adjustment area 12 is adjacent to other splicing screens 10 along the first direction X, and the first distance D1 of the pixel units 20 in the splicing adjustment area 12 along the first direction X is smaller than the first distance D1 of the pixel units 20 in the central area 11 along the first direction X. Two spacing D2;

The splicing adjustment area 12 is adjacent to other splicing screens 10 along the second direction Y, and the third distance D3 of the pixel units 20 in the splicing adjustment area 12 along the second direction Y is smaller than the third distance D3 of the pixel units 20 in the central area 11 along the second direction Y. Four spacing D4;

Wherein, the first direction X and the second direction Y intersect each other;

When the joint size between two adjacent splicing screens 10 is different, the positions of the turned-on pixel units 20 in the splicing adjustment area 12 of the two adjacent splicing screens 10 are different.

Wherein, the condition that the splicing adjustment area 12 is adjacent to at least one other splicing screen 10 includes that the splicing adjustment area 12 is adjacent to other splicing screens 10 along the first direction X and/or the second direction Y. It can be understood that, since the pitch of the pixel units 20 in the splicing adjustment area 12 is smaller than the pitch of the pixel units 20 in the central area 11, after at least two splicing screens 10 are spliced, the splicing adjustment area 12 can be selected according to the size of the seam. The pixel unit 20 in the corresponding position is used for display, that is, the pixel unit 20 in the corresponding position is selected to be turned on, so that the distance between the pixel units 20 on the edge of the adjacent splicing screen 10 in the pixel unit 20 used for display after the splicing is completed is the same as that in the center The pitch of the pixel units 20 in the area 11 is similar or the same, so as to avoid the excessive difference between the pitch of the pixel units 20 on the edge and the pitch of the pixel units 20 in the central area 11 due to the existence of seams, which will affect the display and improve the display effect of the display panel . Exemplarily, referring to FIG. 3 , after the gap size GAP between two adjacent splicing screens is determined, it can be determined according to the gap size GAP and the second distance D2 of the pixel units 20 in the central area 11 along the first direction.

After the first splicing screen 101, the second splicing screen 102 and the third splicing screen 103 are spliced, the first splicing adjustment area can be determined according to the size of the first splicing seam between the first splicing screen 101 and the second splicing screen 102 121 and the position of the pixel unit 20 turned on in the splicing adjustment area at the first seam in the second splicing screen 102, so that the pixel unit 20 used for display at the first seam along the first direction X has the same pitch as the central area 11 similar. According to the size of the second seam between the first splicing screen 101 and the third splicing screen 103, the third splicing adjustment area 123 and the pixel units turned on in the splicing adjustment area at the second seam in the third splicing screen 103 can be determined 20 so that the pitch of the pixel units 20 used for display at the second seam along the second direction Y is close to that of the central area 11 . Moreover, the position of the pixel unit 20 turned on in the second stitching adjustment area 122 can be determined according to the size of the first stitching seam and the second stitching seam, so as to ensure that the pixel unit 20 used for display at the second stitching adjustment area 122 is aligned along the first direction.
