Electrostatic protection circuit and liquid crystal display

Abstract

The invention provides an electrostatic protection circuit and a liquid crystal display. The electrostatic protection circuit comprises a scan line, a common electrode line, a first thin film transistor, a second thin film transistor, a first connecting member and a second connecting member. The first connecting member and the second connecting member each include a first branch and a second branch. The first branch and the second branch are in a needle tip shape. The sharp point of the first branch is directed at one end of the sharp point of the second branch and is not in contact with each other so as to form a sharp discharge effect to output the static electricity on the scanning line to the common electrode line or to output the static electricity on the common electrode line to the scanning line. The electrostatic protection circuit of the present invention achieves an anti-static effect when generating static electricity, and does not affect the normal charging of the pixel during normal operation, such that the display screen of the liquid crystal display is not affected.

Description

technical field [0001] The invention relates to the technical field of manufacturing liquid crystal displays, in particular to an electrostatic protection circuit and a liquid crystal display. Background technique [0002] A liquid crystal display is a commonly used flat panel display at present, and a thin film transistor liquid crystal display is a mainstream product in the liquid crystal display. In the continuous development of liquid crystal display, its product performance and reliability are also continuously enhanced, especially its electrostatic protection ability. With the continuous update of design and continuous improvement of technology, the electrostatic protection ability is steadily improving step by step. , so that the reliability of the product is greatly enhanced. [0003] refer to figure 1 , figure 1 It is a schematic diagram of the circuit structure of the static electricity protection in the existing liquid crystal display. The static electricity p...
