Abstract

The invention discloses a dual-gate driving pixel structure with a line defect repair function. The pixel structure comprises scanning lines, data lines, pixel electrodes and thin-film transistor switches. Two sides of each data line are connected with the pixel electrodes of one pixel through the thin-film transistor switches. Gates of the transistor switches are respectively connected with the scanning lines on the upper side and the lower side. H-shaped repair lines are designed between the upper and lower rows of the pixels. By being combined with a line defect repair method, the breakage defects of the scanning lines can be repaired, and breakage defects of the scanning lines and the data lines and short circuit line defects of the scanning lines and the data lines can be repaired as well.

Description

technical field [0001] The invention relates to the field of flat panel display, in particular to a pixel structure utilizing a liquid crystal display, a manufacturing method and a repairing method thereof. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (hereinafter referred to as TFT-LCD) has the advantages of light weight, thin thickness and low power consumption, and is widely used in electronic products such as TVs, mobile phones, and monitors. In order to reduce the number of driver ICs and develop low-cost and high-quality TFT-LCDs, dual gate technology is usually used to drive pixels in the prior art to shorten the charging time of pixels to achieve low-cost and high-quality image display. [0003] The schematic diagram of the pixel structure using double gate technology is as follows: figure 1 As shown, in the same row of pixels, two pixel units such as P13 and P14 are distributed along the data line 12. Each pixel unit is composed of a sc...
