Array substrate and short-circuit repair method thereof and display device

Abstract

The invention provides an array substrate and a short-circuit repair method thereof and a display device. The array substrate comprises a first conducting wire and a second conducting wire which are mutually and spatially crossed and insulated, and further comprises a spare repair wire; the spare repair wire is arranged on the crossed portion between the first conducting wire and the second conducting wire, the first conducting wire and the second conducting wire are located on different layers, and the spare repair wire can conduct cutting and repairing on the first conducting wire or the second conducting wire close to the spare repair wire when the first conducting wire and the second conducting wire are in short circuit on the crossed portion. Compared with the situation that in the prior art, the spare repair wire is cut off in short-circuit and signal wires to be repaired are arranged on a same layer, the insulation distance between the spare repair wire and the uncut conducting wire is increased, accordingly the possibility of short-circuit between the spare repair wire and the uncut conducting wire is reduced, and thus reliable repairing of the cut conducting wire in short-circuit is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to an array substrate, a method for repairing a short circuit thereof, and a display device. Background technique [0002] Liquid crystal display devices are more and more favored by people because of their thinner and thinner, lower display power consumption and better display effects. [0003] A liquid crystal display device is usually formed by combining an array substrate and a color filter substrate and pouring liquid crystal between them. The array substrate is provided with switching tubes, various driving signal lines and pixel electrodes, and the color filter substrate is provided with common electrodes. The entire liquid crystal display device controls the electric field formed between the pixel electrodes and the common electrodes through the switching tubes and various driving signal lines. , so as to control the deflection of the liquid crystal to realize the...

AI Technical Summary

Problems solved by technology

[0005] In the existing signal line short-circuit repair method, since the first signal line 41 of the two signal lines where the short circuit occurs is arranged in the same layer as the spare repair line 3 for repairing it, when the first signal line 41 is cut off and repaired Afterwards, there is still a spatial cross between the spare repair line 3 and another uncut second signal line 4, so there will inevitably be a short circuit between the two at the cross position

In addition, since the first signal line 41 and the spare repair line 3 for repairing it are arranged in the same layer and connected to each other, a certain gap width needs to be maintained between the two to ensure that they will not be electrically connected to each other, which will The layout area occupied by the spare repair line 3 and the first signal line 41 arranged on the same layer increases, which is not conducive to the wiring design of the signal lines on the array substrate
