Abstract

The embodiment of the invention discloses an electrostatic discharge unit, comprising a first branch circuit and a second branch circuit, the first branch circuit comprises at least one first bigrid thin film transistor; the second branch circuit comprises at least one second bigrid thin film transistor; the first branch circuit is connected with the second branch circuit in parallel, a common first endpoint is used for being electrically connected to a protected circuit, a common second endpoint is used for being electrically connected to a common electrode wire, and the first bigrid thin film transistor and the second bigrid thin film transistor are opposite in conducting direction. The embodiment of the invention also discloses an array substrate and a liquid crystal display panel. By adopting the electrostatic discharge unit disclosed by the embodiment of the invention, the advantage of being beneficial to realization of a narrow bezel of the liquid crystal display panel is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electrostatic discharge unit, an array substrate and a liquid crystal display panel. Background technique [0002] Liquid crystal display panels have become display panels for mobile communication devices, PCs, TVs, etc. due to their high display quality, low price, and easy portability. The currently widely used liquid crystal display panel is usually composed of an array substrate, a color filter substrate and an intermediate liquid crystal layer. [0003] In the production process of liquid crystal display panels, static electricity will be generated in processes such as drying, etching, alignment film friction, cutting and handling. In order to prevent static electricity from damaging the display panel, usually, for example, an electrostatic discharge circuit is provided on the array substrate of the liquid crystal display panel to release the high level generated by the...
