Problems solved by technology

[0004] However, in the existing data line repair method, cutting the data line by laser cutting technology will also expose the storage capacitor line in the insulating film layer, and the wiring debris generated when cutting the data line will often adhere to the storage capacitor line. In general, these wiring debris will cause the data line and the storage capacitor line to be electrically connected, resulting in leakage between the data line and the storage capacitor line

Abstract

The invention provides a wiring repair method, an array substrate and a display panel. The wiring repair method provided by the invention comprises the following steps: cutting off the portion of a data line located at both sides of a leakage point when a leakage occurs at the intersection of the data line and a scan line; using a repair line to connect the data line located at both sides of the cut-off point; and cutting off a storage capacitor branch line located on a side of the data line, wherein the storage capacitor branch line is connected to a storage capacitor bus, the storage capacitor branch line includes a first segment branch line and a second segment branch line located in a pixel area, the first segment branch line is connected between the storage capacitor bus and the second segment branch line, the second segment branch line is located at an edge position of the pixel area, and the cut-off point of on storage capacitor branch line is located on the first segment branchline. The wiring repair method provided by the invention can prevent a leakage phenomenon when repairing the wiring, and can ensure normal transmission of pixel signals.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a wiring repair method, an array substrate and a display panel. Background technique [0002] With the development of display technology, flat display devices such as liquid crystal displays have been widely used in various large, medium and small products due to their advantages such as thin size, light weight, excellent picture quality, low power consumption, long life, digitalization and no radiation. Widely used, covering almost the main electronic products in today's information society. [0003] During the manufacturing process of the array substrate of the liquid crystal display, due to the complicated production process and the influence of factors such as foreign matter or static electricity damage in the environment, the insulating film layer between the data line and the scanning line in the array substrate is often damaged, resulting in Leakage occurs ...
