Title:
ELECTROSTATIC PROTECTION CIRCUIT, ARRAY SUBSTRATE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/103510
Kind Code:
A1
Abstract:
An electrostatic protection circuit, an array substrate, and a display device. In practical applications, a first electrostatic discharge end (V1) and a second electrostatic discharge end (V2) in the electrostatic protection circuit are respectively coupled to an electrostatic protection line such as a common electrode line and a high/low potential reference voltage line; and a signal line connection end (L1) is coupled to a signal line such as a gate line and a data line. When the voltage formed by static charge accumulated on the signal line is too large or too small (the absolute value is very large), the signal line can be connected to the electrostatic protection line by means of a transistor in a first electrostatic discharge circuit (1) or a second electrostatic discharge circuit (2), so that effective electrostatic discharge of a signal line in a product can be implemented without affecting the implementation of normal functions thereof.
