Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] During the array process and box-forming process of TFT-LCD, the array substrate will have a data line disconnection or a short circuit between the data line and the scanning line due to factors such as heat generation, etching parameters, glass substrate residues, and equipment errors. Problems such as data line failure, such as figure 1 As shown, the fault location is displayed in black dots, the electrical signal is transmitted from top to bo...

Abstract

The present invention provides an array substrate and a maintenance method thereof, a display panel and a display device, wherein the method includes: when a fault occurs on the nth data line, processing the fault location so that the fault location forms an open circuit; cutting and repairing obtain a local repair line, and use the local repair line to connect the rear segment of the nth data line at the fault location to the mth data line to form a conductive path. The array substrate and its maintenance method, display panel and display device provided by the present invention have a simple maintenance method, can avoid the loss of sub-pixels, and ensure the display effect of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a maintenance method thereof, a display panel and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, thin film transistor liquid crystal display for short), with its advantages of thinness, environmental protection, high performance, etc., has been widely used and has become the mainstream product in LCD applications. [0003] In the prior art, during the array process and box forming process of TFT-LCD, the array substrate will inevitably cause the data line to be disconnected or the data line to be disconnected due to factors such as heat generation, etching parameters, glass substrate residues, and equipment errors. Faults on the data line, such as short-circuiting with the scan line, cause the signal to fail to be transmitted to the sub-pixels behind the faulty location, and the screen display ...
