Abstract

The invention relates to an FFS (Free Fall Sensor) type TFT-LCD (Thin Film Transistor-Liquid Crystal Display) array substrate and a manufacture method thereof. The array substrate comprises a grid line, a first data line and a second data line which are formed on the substrate and limit a pixel area, wherein a common electrode, a first TFT, a second TFT, a first pixel electrode and a second pixelelectrode are formed in the pixel area; the first data line provides a first data signal to the first pixel electrode through the first TFT; the second data line provides a second data signal to the second pixel electrode through the second TFT; the first data signal and the second data signal have opposite relative polarities; and the first pixel electrode and the second pixel electrode are alternately arranged. The invention improves the equality of an electric field and has higher whole transmissivity in one aspect, improves the strength of a horizontal electric field in the other aspect, has favorable charging and discharging characteristics of the pixel electrodes, not only can improve the driving efficiency and the panel transmissivity, but also is favorable to power consumption reduction and afterimage elimination.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display and a manufacturing method thereof, in particular to an FFS type TFT-LCD array substrate and a manufacturing method thereof. Background technique [0002] In recent years, thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD for short) has the characteristics of small size, low power consumption, no radiation, high display resolution, etc., and has begun to be widely popularized and become a mainstream product. Fringe Field Switching (FFS for short) is one of the technologies that have appeared in recent years that can improve the image quality of LCDs, and can simultaneously achieve the requirements of high penetration and large viewing angles. [0003] At present, the prior art FFS type TFT-LCD array substrate usually adopts the structure of single gate and single pixel electrode, including the common electrode, gate line and gate elect...
