Display panel and display device

Abstract

The invention provides a display panel and a display device. The display panel comprises a light-emitting surface and a non-light-emitting surface; the light-emitting surface and the non-light-emitting surface are oppositely arranged; the display panel further comprises a frame area, a pixel area, a bending area and a binding area. The frame region surrounds the pixel region; the frame area is connected with the bending area; the frame area comprises at least one alignment mark group; the alignment mark group comprises a first alignment mark, a second alignment mark and a third alignment mark;the second alignment mark, the first alignment mark and the third alignment mark in the first alignment mark group are sequentially arranged in the extending direction of the pixel column in the pixel area; the bending area is bent to the non-light-emitting surface from the side of the frame area; the bending area is connected with the binding area; the binding area is arranged on the non-light-emitting surface; the binding area comprises fourth alignment marks corresponding to the alignment mark groups; and the first alignment mark is aligned with the fourth alignment mark. Therefore, the alignment mark group and the fourth alignment mark are used for improving the alignment precision of the binding area in the extending direction of the pixel column.

Description

【Technical field】 [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] A major trend of existing display panels is full screen. [0003] figure 1 It is a schematic diagram of a display panel in the prior art. [0004] Such as figure 1 As shown, in the prior art, the display panel P includes a light emitting surface S. As shown in FIG. The display panel P also includes a pixel area AA and a binding area BA. The pixel area AA and the binding area BA are located on the side of the light emitting surface S. The pixel area AA is used for displaying images, and the binding area BA is used for setting the driver chip. The binding area BA occupies a certain area on the side of the light-emitting surface S, which affects the visual effect. In order to improve the visual effect and reduce the frame of the flexible screen, the frame will be reduced as much as possible. B...

Problems solved by technology

At present, a commonly used design in the industry is to lithographically engrave two sets of Marks on the flexible screen. When bending, the relative positions on the Marks are calculated and grasped to align the bending. However, the bending accuracy of this solution is low. Moreover, flexible screens are difficult to rework, so the yield rate is relatively low
