FFS (Free Fall Sensor) type TFT-LCD (Thin Film Transistor-Liquid Crystal Display) array substrate and manufacture method thereof

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 pixel electrode 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 involves a film crystal liquid crystal display and its manufacturing method, especially a FFS TFT-LCD array substrate and its manufacturing method. Background technique [0002] In recent years, because the Thin Film Transistor LiquidCrystal Display (TFT-LCD) has the characteristics of small size, low power consumption, no radiation, high display resolution, etc., it has begun to popularize and become mainstream products.Fringefield Switching (FFS) is one of the technologies that can improve LCD image quality in recent years, and can also achieve high penetration and large perspective requirements at the same time. [0003] At present, the existing technology FFS TFT-LCD array substrate is usually a single grid and a single pixel electrode structure, including the formation of public electrodes, grid lines, and grid electrodes formed on the substrate.The grid insulation layer is located above the grid electrode, one end of the source electrode...

AI Technical Summary

Problems solved by technology

Although this solution improves the charging and discharging characteristics of the pixel electrode by connecting part of the pixel electrode to the common electrode structure, it reduces the fringe electric field strength and seriously reduces the transmittance.
