Problems solved by technology

[0006] Electrostatic discharge will lead to a decrease in the yield of LCD panels, an increase in cost, and a decrease in production capacity. Therefore, ESD monitoring is required during the production of LCD panels
At present, the ESD monitoring method used for liquid crystal display panels is mainly to detect the display area of ​​the liquid crystal display panel by taking pictures and testing machines and telecommunications testing machines, and when ESD is detected, the product quality of the liquid crystal display panel has already been affected. influences

Abstract

The invention provides a liquid crystal display panel and a liquid crystal display panel ESD monitoring method. According to the liquid display panel structure, multiple sets of electrostatic discharge testing elements (5) which are horizontally arranged at intervals in the first direction are arranged on the wireless peripheral area of a TFT array substrate (1), each set of the electrostatic discharge testing elements comprises two metal test bars (51) which are oppositely arranged in a spacing mode in the second direction perpendicular to the first direction, the opposite ends of the two metal test bars (51) serve as tips (511), and occurrence of electrostatic discharge is induced easily. Therefore, by means of monitoring of the electrostatic discharge testing elements (5), occurrence of liquid crystal display panel ESD can be monitored continuously in time, occurrence risks of the ESD can be foreseen, and improvement on products can be facilitated.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel structure and a liquid crystal display panel ESD monitoring method. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen etc. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal display panel disposed in the housing, and a backlight module (Backlight Module) disposed in the housing and opposite to the liquid crystal display panel. [0004] The structure of the liquid crystal panel is usually composed of a color filter substrate (ColorFilter, CF), a thin film transistor array substrate (ThinFilmTransistorArraySubst...
