Problems solved by technology

[0004] However, under the high-voltage electrostatic test conditions above 2KV, external static electricity enters the interior through seal glue and other paths. Due to the limited antistatic ability of the ESD circuit, the ESD circuit and VSR circuit are often broken down and burned, resulting in abnormal panel display. doesn't even work

Abstract

An embodiment of the invention provides a substrate, a display panel and a display device. The substrate comprises a substrate body, a wire arranged on the periphery of the substrate body, an insulating layer arranged on the wire, insulating frame glue and electricity-conductive frame glue, wherein the insulating frame glue and electricity-conductive frame glue are arranged on the insulating layer. The insulating layer comprises through holes for exposing the wire. The electricity-conductive frame glue is electrically connected with the wire through the through holes and directly contacts with the insulating frame glue. When external static electricity intends to enter the panel through a position between CF and TFT (thin film transistor) substrates, electrostatic charges can be guided to a ground wire through the electricity-conductive frame glue to be guided away, and the insulating frame glue can play a role in protecting an internal circuit.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an antistatic substrate, a display panel, and a display device. Background technique [0002] The electrostatic protection design of electronic products is one of the necessary conditions to ensure their normal operation. As an electronic product, a liquid crystal display device faces a lot of static electricity from mechanical equipment, human body or other electronic equipment during production, transportation, testing and use. Due to the dense wiring of the gate driving circuit formed on the array substrate, external static electricity can enter the gate driving circuit through the gap between the array substrate and the color filter substrate, thereby causing damage to the gate driving circuit. [0003] In the current industry, due to the increasing anti-static requirements of customers and final consumers, preventing electrostatic breakdown has become an important issue. ...
