Abstract

The embodiment of the invention discloses an electrostatic discharge circuit, an array substrate and a display device. Wherein, the electrostatic discharge circuit includes: at least one signal transmission line, any signal transmission line includes an electrostatic discharge line section, the electrostatic discharge line section includes at least one discharge branch and at least one protection branch, and the discharge branch and the protection branch are connected in parallel, wherein, One side of the discharge branch is provided with at least one first discharge tip; at least one auxiliary discharge circuit corresponds to the discharge branch respectively, and at least one second discharge tip is provided on the side of the auxiliary discharge circuit close to the discharge branch, and the second discharge tip of the auxiliary discharge circuit Corresponding to the first discharge tips of the corresponding discharge branches respectively, and the tip of the first discharge tip is directly opposite to the tip of the corresponding second discharge tip and maintains a preset gap. The technical solutions of the embodiments of the present invention can improve the electrostatic protection function of the display device and improve the yield rate of products.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electrostatic discharge circuit, an array substrate and a display device. Background technique [0002] Liquid Crystal Display (LCD) has been widely used due to its light weight, thin thickness, low power consumption and other advantages. However, in the production process of liquid crystal displays, the defect rate caused by electrostatic discharge (ESD) damage has been high all the time, and has even become the number one defect factor of liquid crystal displays. [0003] Although strict anti-static measures have been implemented on all current LCD production lines, such as the use of photoresist materials that are not prone to static electricity, the use of dust-free clothing and cleanliness control, and the use of moisturizing and ion fans, static electricity is still constant. It threatens the production yield of liquid crystal displays all the time, and even threatens ...

However, in the production process of LCDs, the defect rate due to Electro-Static discharge (ESD) damage has always been high, and has even become the number one defect factor of LCDs.

[0003] Although strict anti-static measures have been implemented on all current LCD production lines, such as the use of photoresist materials that are not prone to static electricity, the use of dust-free clothing and cleanliness control, and the use of moisturizing and ion fans, static electricity is still constant. It is always threatening the production yield of LCDs, and even the lifespan of end users using LCDs.
