Abstract

The invention is a pixel structure, includes the following components. The Scanning lines and data lines are on the base plate. The first, second and third thin-film transistor respectively connects with the scanning line electrically. The second and third thin-film transistor channel has the same ratio of width to length, which is larger than the first one. The first, second and third share line is respectively set under the three pixel electrodes, in which, the first and second ones meet electricity linking with the first voltage, and the third one links with the second voltage. When this pixel structure is drive, the first, second and third thin-film transistors will produce different charging rate, to improve the color deflection.

Description

technical field [0001] The present invention relates to a pixel structure, and in particular to a pixel structure of a liquid crystal display. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) has gradually become the mainstream of the market due to its superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation. Currently, the performance requirements of the market for liquid crystal displays are towards high contrast (High Contrast Ratio), fast response and wide viewing angle. At present, technologies that can meet the requirements of wide viewing angles, such as Multi-domain Vertical Alignment (MVA), Multi-domain Horizontal Alignment (MHA), Twisted Nematic plus wideviewing film, TN+film) and transverse electric field (In-Plane Switching, IPS). [0003] Although the multi-domain vertically aligned thin film transistor liquid crystal display can achieve the purpose of wid...
