Thin-film transistor array substrate, its electric static discharge protector and method for making same

Abstract

The TFT array substrate comprises: multiple scanning wirings with a first short-circuit bar on one side, multiple data wirings with a second short-circuit base on side, and static discharge protective elements every with a switch element to conduct over-charge to bar and a paralleled resistance wire fit to detect damaged pixel.

Description

technical field [0001] The invention relates to a thin film transistor array substrate and a manufacturing method thereof, and in particular to a top gate type thin film transistor array substrate, an electrostatic discharge protection element thereof and a manufacturing method thereof. Background technique [0002] Electrostatic discharge is the phenomenon of the movement of static electricity from non-conductive surfaces, which can cause damage to components in integrated circuits and other circuit components. For example, a human body walking on a carpet can detect a static voltage of several hundred to several thousand volts when the relative humidity is high, and a static voltage of about 10,000 volts can be detected when the relative humidity is low. quiescent voltage above volts. [0003] Generally, in the manufacturing process of liquid crystal displays, many machines and personnel will be operated, and the machines and personnel will be charged with static electric...
