Problems solved by technology

During the instantaneous discharge of the static electricity on the repair lines R1 and R2, it will cause adverse consequences such as electrostatic breakdown to the connected data line DL or the electrode line on the common electrode layer 4. This defect is reflected in the display as the failure of the data line. Insufficient writing, even the data line cannot be written
[0006] Since the repair line traverses the entire display area and intersects with all data lines, electrostatic damage to data lines caused by static electricity on the repair line is relatively common, which will affect the display effect of the entire TFT-LCD panel

Abstract

The invention relates to a liquid crystal display and a repairing method thereof. The liquid crystal display comprises a glass substrate, data wire input end submodules formed on the glass substrate, repairing lines formed on the same sides and opposite sides of the data wire input end submodules, and a common electrode layer between the data wire input end submodules, wherein the repairing lines on the same sides of the data wire input end submodules are connected with the common electrode layer so that the repairing lines have a stable electric potential. Therefore, the liquid crystal display and the repairing method thereof can prevent the repairing lines from generating electro-static damage and improve the yield of the liquid crystal display.

Description

technical field [0001] The invention relates to a liquid crystal display and a repairing method thereof, in particular to a liquid crystal display and a repairing method thereof capable of preventing electrostatic damage of repairing lines. Background technique [0002] In recent years, liquid crystal displays, especially thin film transistor liquid crystal displays (Thin Film Transistor Liquid Crystal Display, hereinafter referred to as "TFT-LCD"), have gradually become the mainstream displays in the development of various display devices due to their thinness, lightness, energy saving, and environmental protection. [0003] In the existing TFT-LCD display, many data lines are densely covered on one side of the TFT-LCD array substrate. When one of the data lines is disconnected, a line defect will appear on the TFT-LCD panel, thereby affecting the quality of the TFT-LCD product. Qualification rate and display effect. So far, many companies have proposed a variety of design...
