Abstract

The invention provides an array substrate, a repairing method thereof, a display panel and a display device. The method includes the steps of connecting a grid line at the first end of an open-circuitposition with a source of a TFT and connecting a grid line at the second end of the open-circuit position with a data line when an open circuit appears on the grid line between the TFT and a data line, cutting the data line at the two ends of the joint of the grid line and the data line to open a local data line, and forming a conductive close circuit between the data line at the first end of thecutting position and the data line at the second end of the cutting position through two public electrode lines and a public electrode line compensation structure and a public electrode between the two public electrode lines. By means of the array substrate, the repairing method thereof, the display panel and the display device, the repairing cost of the array substrate can be reduced, and the display effect of the display device is ensured.

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 be located between the TFT and the data line due to factors such as heat generation, etching parameters, glass substrate residues, and equipment errors. The problem of the open circuit of the gate line between the gate lines causes the signal to be unable to be transmitted to the pixel area behind the open circuit position, and the screen display is abnormal. C...
