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

Embodiment 1

[0033] This embodiment provides an array substrate, such as figure 2 As shown, it includes a first conductive wire 1 and a second conductive wire 2 that intersect each other and are insulated in space, and also includes a spare repair wire 3, and the spare repair wire 3 is arranged at the intersection position P of the first conductive wire 1 and the second conductive wire 2 , and is located in a different layer from the first conductive wire 1 and the second conductive wire 2, the spare repair wire 3 can short-circuit the first conductive wire 1 and the second conductive wire 2 at the intersection position P 1 or the second conductive wire 2 for cut repair.

[0034] In this embodiment, one of the first conductive wire 1 and the second conductive wire 2 that is closer to the backup repair wire 3 is selected and cut off at the crossing position P, and the backup repair wire 3 is used to connect and repair it. As in this embodiment, the first conductive wire 1 is closer to the...

Embodiment 2

[0044] This embodiment provides an array substrate, and the difference from Embodiment 1 is that, as image 3 As shown, the second conductive wire 2 is closer to the backup repair wire 3 than the first conductive wire 1 . Therefore, when the short circuit is repaired, the second conductive wire 2 is cut off at the intersection position P, and the second conductive wire 2 is connected and repaired by using the spare repair wire 3 .

[0045] Correspondingly, the orthographic projections of the two ends of the spare repairing line 3 on the array substrate are located on the second conductive line 2 close to it. Such setting is convenient for when the first conductive wire 1 and the second conductive wire 2 are short-circuited at the intersection point, the two ends of the spare repair wire 3 are connected with the second conductive wire 2 cut off at the intersection point, so as to The second conductive wire 2 is repaired.

[0046] Such as image 3 As shown, in this embodiment...

Embodiment 3

[0054] This embodiment provides a display device, including the array substrate in Embodiment 1 or 2.

[0055] By using the array substrate in Embodiment 1 or 2, the reliability of the display device after short-circuit repair is improved, thereby improving the quality of the display device.

[0056] The display device provided by the present invention can be any product or component with a display function, such as a liquid crystal panel, a liquid crystal TV, an OLED panel, an OLED TV, a monitor, a mobile phone, or a navigator.

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...
