Display panel

Abstract

The invention relates to the technical field of semiconductor processing and particularly relates to a display panel which comprises an array base plate, wherein the array base plate is provided with multiple grid lines and multiple data lines; the grid lines are in signal connection with a grid driving module; the data lines are in signal connection with a data driving module; the display panel further comprises grid line redundancy lines which are in one-to-one correspondence with the grid lines and data line redundancy lines which are in one-to-one correspondence with the data lines; one end of each grid line redundancy line is in signal connection with the grid driving module, the other end of each grid line redundancy line is connected with the corresponding grid line by virtue of a first control switch, and the grid line redundancy lines are used for receiving signals same as the corresponding grid lines; and one end of each data line redundancy line is in signal connection with the data driving module, the other end of each data line redundancy line is connected with the corresponding grid line by virtue of a second control switch, and the data line redundancy lines are used for receiving signals same as the corresponding data lines. The display panel provided by the invention can be used for better maintaining broken line defects on the array base plate.

Description

technical field [0001] The invention relates to the technical field of semiconductor processing, in particular to a display panel. Background technique [0002] In the field of semiconductor processing technology, the manufacturing process of display devices is very complicated. During the manufacturing process of the array substrate of the display panel, the array substrate will inevitably have various defects due to process errors. Among them, the disconnection defect in the array substrate It is a kind of defect that most affects the quality of display panels and display devices, and the occurrence rate of disconnection defects is very high. Therefore, in order to improve the yield rate of the display device, it is necessary to repair these breakpoints after the broken wires occur, so as to repair the broken wires. [0003] In the prior art, there are mainly two ways to repair the faulty disconnection of the array substrate: [0004] One is to use CVD equipment on the A...

Problems solved by technology

This method has a certain repairing effect for small-sized products, but since the maintenance line 13 is formed on the same surface as the signal line, an intersection will occur at the intersection position 113 between the maintenance line 13 and the intersection position 113 of the signal line 11. Overlap capacitors, causing signal delay; at the same time, in the face of large-scale liquid crystal display products, this method cannot be repaired, and with the wiring situation of the prior art, at most two repair lines 13 can only be laid, that is, at most only repair two broken wires 12
