Embodiment 1

[0025] Embodiment 1 of the present invention provides a display panel, including: an array substrate and a plurality of source driving circuits, and the array substrate has a plurality of display areas corresponding to the plurality of source driving circuits one-to-one, wherein, There are multiple data lines in each display area, and the multiple data lines in the display area are connected to the corresponding source drive circuit. When a bad point occurs on the data line, in order to be able to repair the data line, the At least one first display area in the plurality of display areas has a maintenance line uniquely corresponding to the first display area, and the maintenance line is used to perform maintenance on the data lines in the corresponding first display area, the The maintenance line is only connected to the source driving circuit corresponding to the corresponding first display area.

Embodiment 2

[0027] Such as figure 2 Shown is a schematic structural view of a display panel according to an embodiment of the present invention. The display panel includes: an array substrate 200 and four source drive circuits (401a, 401b, 401c, 401d), and the array substrate 200 has a The four source drive circuits correspond to the four display areas (201a, 201b, 201c, 201d) one by one, wherein the source drive circuit 401a corresponds to the display area 201a, the source drive circuit 401b corresponds to the display area 201b, and the source The driving circuit 401c corresponds to the display area 201c, and the source driving circuit 401d corresponds to the display area 201d. There are multiple data lines in each display area, and the multiple data lines in the display area correspond to the corresponding source driving circuit. connect.

[0028] Under normal circumstances, the data lines in the display area are directly connected to the corresponding source drive circuit, and the so...

Abstract

The invention provides a display panel and a display device. The display panel comprises an array substrate and a plurality of source drive circuits, wherein a plurality of display areas corresponding to the plurality of source drive circuits one to one are arranged on the array substrate; a plurality of data lines are arranged in each display area; the plurality of data lines in each display area are connected to the corresponding source drive circuits; at least one first display area in the plurality of display areas is provided with a maintenance line corresponding to the first display area solely; the maintenance line is used for maintaining the data lines in the corresponding first display area; and the maintenance line is connected with the source drive circuit corresponding to the first display area only. According to the invention, one maintenance line can be used independently in the display areas to maintain the data lines. When one maintenance line is used independently, an operation of cutting off maintenance lines is avoided, thereby simplifying processes, and increasing the number of defective pixels capable of being maintained.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The liquid crystal panel mainly includes an array substrate and a color filter substrate arranged opposite to each other, and a liquid crystal layer is filled between them. The array substrate has a plurality of gate lines and data lines intersecting horizontally and vertically, and the plurality of gate lines and data lines enclose a plurality of display areas. After the array substrate and the color filter substrate are boxed together, there may be a defect that the data line is broken. In the prior art, a repair line is usually used to repair the data line. [0003] Such as figure 1 Shown is a schematic structural view of a display panel in the prior art, the display panel has four source driver circuits (S-IC) 104a, 104b, 104c, 104d and two maintenance lines 101a and 101b, each source The drive ci...
