Static electricity release structure for liquid crystal display panels, liquid crystal display panel and liquid crystal display

Abstract

The embodiment of the invention discloses a static electricity release structure for liquid crystal display panels, which is used on a liquid crystal display panel on which a high-resistance film is attached. The uppermost layer of glass panel of the liquid crystal display panel is covered by a layer of high-resistance film, moreover, an edge is reserved around the high-resistance film, a conductive material layer is arranged on the reserved edge of the glass panel, the conductive material layer is in contact with the circumference of the high-resistance film, and the conductive material layer is connected to GND pins of a TFT (Thin Film Transistor) substrate through conductive silver adhesive. The embodiment of the invention further discloses a corresponding liquid crystal display panel and a corresponding liquid crystal display. According to the embodiment of the invention, the release of static electricity can be accelerated, and the generation of static electricity by film tearing and film attachment is greatly improved.

Description

technical field [0001] The invention relates to thin film transistor (Thin Film Transistor, TFT) technology, in particular to an electrostatic discharge structure of a liquid crystal display panel, a liquid crystal display panel and a liquid crystal display. Background technique [0002] In the existing technology, the surface of the IPS (In-Plane Switching, in-plane switching) display screen must have a grounded shielding layer, otherwise the external electric field will affect the flipping state of the liquid crystal molecules, resulting in poor display; [0003] In addition, the self-capacitance incell display (a display that embeds the touch panel function into the LCD pixels) has a well-grounded shielding layer, which will completely shield the touch signal in the box, so it is necessary to coat the surface with a layer of high Anti-shielding layer, which can not only shield low-frequency electrostatic shock, but also transmit high-frequency touch signals; [0004] Sin...

AI Technical Summary

Problems solved by technology

[0006] First, replace the supplier of the protective film. However, because the surface impedance of the material used for the protective film of each manufacturer is different, the type of matching is also different;

[0007] Second, increase the area of ​​silver glue and accelerate the discharge of static electricity. However, this will increase the difficulty of the process, the risk of glue overflow will be greater, and the cost will increase greatly; and it is impossible to use a multimeter to measure whether the silver glue is conductive.
