Pixel structure and film transistor array

Abstract

The present invention relates to a pixel structure and film transistor array. It is composed of first patterned conductor layer with scan line, first dielectric layer, several channel layer, second patterned conductor layer including signal line and source / drain, second dielectric layer and several pixel electrodes, in which first patterned conductor layer is positioned on a base plate, the first dielectric layer is positioned on the base plate and is used for covering first patterned conductor layer, the channel layer is positioned on first dielectric layer over scan line. The second patterned conductor layer is positioned on first dielectric layer, its source and drain are positioned at two sides of channel layer on scan line, the second dielectric layer is positioned on first dielectric layer and is used for covering second patterned conductor layer, the pixel electrode is placed on second dielectric layer, its pixel electrode is electrically connected with one end of source / drain, andanother end of source / drain is electrically connected with signal line.

Description

technical field [0001] The present invention relates to a pixel structure and a thin film transistor array of a liquid crystal display, and in particular to a pixel structure and a thin film transistor array capable of reducing the variation value of the gate-drain capacitance (Cgd) of the thin film transistor. Background technique [0002] Liquid crystal display is a kind of flat-panel display, which has the advantages of high image quality, small size, light weight, low voltage drive, low power consumption and wide application range. Therefore, it has been widely used in medium and small portable TVs. , mobile phones, camcorders, notebook computers, desktop monitors and projection TVs and other consumer electronics or computer products. At present, the development of liquid crystal display can be roughly divided into active matrix liquid crystal display (Active Matrix LCD) and passive matrix liquid crystal display (Passive Matrix LCD). Among them, active matrix liquid crys...

AI Technical Summary

Problems solved by technology

In the thin film transistor array, the variation of the gate-drain capacitance (Cgd) will easily cause stitching block (shot mura) and other phenomena during display.

[0005] In addition, in the existing pixel structure, when the thin film transistor fails due to improper process control or other factors, there will often be bright spots that are difficult to repair, which will affect the display quality
