Array substrate, liquid crystal display panel and liquid crystal display device

Abstract

The invention discloses an array substrate. The array substrate comprises a common electrode layer, a pixel electrode layer, an effective display area and a virtual pixel area on the peripheral side of the effective display area. In the virtual pixel area, the voltage difference between the pixel electrode layer and the common electrode layer of the array substrate is always zero; a thin film transistor in the virtual pixel area and a thin film transistor in the effective display area are of the same structure. The array substrate can improve the electrostatic protection ability of real pixelsin the effective display area, lower the probability of abnormal displaying due to ESD injury generated by the real pixels on the edge of the effective display area, and accordingly improves the production yield of products to a certain degree. The invention further discloses a liquid crystal display panel and a liquid crystal display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate, a liquid crystal display panel and a liquid crystal display device. Background technique [0002] Among flat-panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) panels have the characteristics of small size, low radiation and relatively low manufacturing costs, and have been widely used in electronic products such as mobile phones, computers, and televisions. Wide range of applications. [0003] In integrated circuit components, electrostatic discharge (Electro-Static Discharge, ESD) is a common phenomenon. ESD can lead to the breakdown of the insulating medium, which will cause the drift of the threshold voltage or the short circuit between the gate and the source and the drain, which will cause abnormal display, component failure or shorten the service life of the component. At present, with the development of techno...

Problems solved by technology

ESD can lead to the breakdown of the insulating medium, which will cause the drift of the threshold voltage or the short circuit between the gate, the source, and the drain, which will cause abnormal display, component failure or shorten the service life of the component.

At present, with the development of technology and the higher level of circuit integration, the wiring density of components on the TFT-LCD panel increases, the wiring distance shortens, and the withstand voltage of components decreases, resulting in the electrostatic protection of components.
