Liquid crystal display panel

Abstract

The invention provides a liquid crystal display panel comprising a testing end, a static protective circuit and a ground end. The testing end is formed by a plurality of testing pads; the static protective circuit is formed by a plurality of protective circuit units; the plurality of testing pads and the plurality of protective circuit units are in one-to-one corresponding connection; one end of each protective circuit unit is connected with the corresponding testing pad and the other end is connected with the ground end; and each protective circuit unit consists of one or a plurality of sub-circuit units. Electrostatic discharge of the liquid crystal display panel does not pass through the interior of the liquid crystal panel, so damage of the electrostatic discharge can be reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display panel. Background technique [0002] Currently, electrostatic discharge (Electro-Static Discharge, ESD) has become a hazard to electronic products and equipment, causing dysfunction and even damage to electronic products and equipment. In particular, some small-sized GIA-type (GateInArray, ie gate drivers are integrated on the array substrate) display panels often suffer from electrostatic damage. [0003] When the liquid crystal display panel is impacted by electrostatic discharge, the static protection circuit provided on the liquid crystal display panel can disperse and weaken the static electricity, so as to avoid the static electricity from directly impacting the components and circuits inside the display area. Please refer to figure 1 , figure 1 It is a schematic diagram of a circuit structure of a liquid crystal display panel in the prior a...

Problems solved by technology

[0004] During the test, when the needle sticks or the signal is abnormal, a large current will be generated instantaneously, and according to the design of the electrostatic protection circuit 12, these large currents will be shunted to the public through the corresponding protection circuit unit connected to the test terminal 11. electrode 13, but if the instantaneous current is too large to be released in time, it may flow back into the electrostatic protection circuit 12 through the common electrode 13, and break down the thin film transistor in the array substrate of the liquid crystal display panel 10 according to the shortest path, It even enters the place where the scan line and the data line intersect through the wiring and explodes there, resulting in poor display screen lines or even abnormal pictures, resulting in the scrapping of the liquid crystal display panel 10
