Problems solved by technology

For example, when the resolution of the LCD screen is increased to 4K*2K or even 8K*4K, and the traditional 60Hz scanning frequency is increased to 120Hz, 240Hz or even 480Hz, the time for the LCD pixel data line to input data signals becomes very short, only The current 1 / 4, 1 / 8 or even 1 / 16, at this time, there will be a problem of insufficient charging of the LCD pixels, which will affect the quality of the picture display

Abstract

The invention discloses a drive circuit, a drive method thereof and a liquid crystal display. The drive circuit comprises multiple scanning lines and multiple data lines, wherein the scanning lines and the data lines are mutually perpendicular and intersected, and the drive circuit is divided into multiple pixel regions by the multiple scanning lines and multiple data lines. Each pixel region comprises one pixel and at least two thin film transistors, wherein a grid electrode and a source electrode of each thin film transistor are respectively connected with one scanning line and one data line, and a drain electrode of each thin film transistor is connected with the corresponding pixel. At least two thin film transistors are respectively used for charging the pixels when being opened. In the mode, the charging time of the pixels can be increased, and the picture quality of the liquid crystal display can be improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a driving circuit, a driving method thereof, and a liquid crystal display. Background technique [0002] Liquid crystal displays have the characteristics of low radiation, low power consumption, and small size, and have gradually become the mainstream of display devices, and are widely used in mobile phones, notebook computers, flat-panel TVs and other products. [0003] figure 1 For the pixel structure and driving method of the commonly used liquid crystal panel at present, a sub-pixel P 1 , through a scan line G 1 Drive a corresponding data line D 1 It is connected to the sub-pixel electrodes. When the scanning signal is scanned step by step, the TFT of each sub-pixel is turned on in turn, and the data signal is added to the sub-pixel electrodes through the data line to realize the display of the image. [0004] At present, liquid crystal displays are developing in the...
