Problems solved by technology

Among them, although the smaller the resistance value of the protective circuit ring, the higher the ability to disperse and accumulate static electricity, but it is easy to cause the problem of signal interference
Therefore, the existing protective circuit ring design around the panel still has limited effectiveness in dispersing the accumulated static electricity in the display area.

Abstract

A liquid crystal display face-plate with protection of static discharge is prepared as setting internal protective circuit ring of short circuit type around periphery of display region and external protective circuit ring of short circuit type around periphery of internal protective circuit ring, connecting external protective circuit ring to display region and internal protective circuit ring, connecting internal protective circuit ring to display region through external protective circuit ring, enabling to connect internal protective circuit ring to be a patch circuit after edging process of face plate is finalized.

Description

technical field [0001] The invention relates to a liquid crystal display panel, and in particular to a liquid crystal display panel with electrostatic discharge protection function. Background technique [0002] In the process of manufacturing liquid crystal display panels driven by thin-film transistors (Thin-Film Transistor; TFT), there is often a phenomenon of static electricity accumulation. The accumulation of static electricity cannot be eliminated, thus easily causing the problem of Electro-Static Discharge (ESD), resulting in damage to components, and greatly reducing the yield rate of LCD components. [0003] During the manufacturing process of thin film transistors, static electricity will be accumulated in some process environments, such as chemical vapor deposition (Chemical Vapor phase Deposition; CVD), sputtering (sputtering) or dry etching and other plasma-related processes. In addition, there are also some static electricity from the outside during the proce...
