Problems solved by technology

Since the voltage polarities of two adjacent frames of the same pixel electrode are exactly opposite, there is a large voltage drop. Therefore, the existing polarity reversal method increases the difficulty of charging and discharging the pixel electrode. On the one hand, the charging and discharging time is longer, and on the other hand On the one hand, the drive power consumption is large

Abstract

The invention relates to a TFT-LCD array substrate and a manufacturing method thereof. The array substrate comprises a gate line and a data line which are formed on a substrate and limit a plurality of pixel areas, wherein a pixel electrode, a first thin film transistor controlling charging of the pixel electrode and a second thin film transistor controlling precharging of the pixel electrode areformed in each pixel electrode. Through forming the first thin film transistor and the second thin film transistor respectively controlling charging and precharging of the pixel electrode in each pixel area, when the pixel electrodes in a pixel row are charged, the pixel electrodes in the adjacent next pixel row realize precharge, thus reducing the difference between the voltage of the frames of the pixel electrodes in the pixel row and the voltage of the next frames, effectively eliminating the defect of higher voltage drop in the polarity inversion mode, effectively shortening the charging / discharging time on the one hand and effectively reducing the drive power consumption on the other hand.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display and a manufacturing method thereof, in particular to a TFT-LCD array substrate and a manufacturing method thereof. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. TFT-LCD mainly includes an array substrate and a color filter substrate that are boxed together with liquid crystal interposed therebetween. Gate lines, data lines, pixel electrodes and thin-film transistors are formed on the array substrate, and each pixel electrode is controlled by a thin-film transistor. When the thin film transistor is turned on, the pixel electrode is charged during the turn-on time, and after the thin film transistor is turned off, the voltage of the pixel electrode will be maintained until recharging i...
