[0049] Referring to FIG. 2 , it is a schematic diagram of a liquid crystal display according to a first embodiment of the present invention. Referring to FIG. 3 at the same time, it is a schematic diagram of a pixel array according to a first embodiment of the present invention. The liquid crystal display 200 includes a backlight module 210 and a liquid crystal display panel 220 having a pixel array 230 . The pixel array 230 includes a plurality of pixel columns L1 ˜ Ln, the pixels of which are respectively coupled to the scan driving circuit 240 through the scan lines 242 and coupled to the data driving circuit 250 through the data lines 252 . The scanning driving circuit 240 is used for providing the scanning voltage to the pixel, and the data driving circuit 250 is used for providing the pixel voltage to the corresponding pixel so as to change the light transmittance of the pixel.

Abstract

A method for driving liquid crystal display includes outputting the first pixel voltage to the first pixel in the first pixel column for varying transmissivity of the first pixel, doing the same thing as above on the second pixel to very transmissivity of the second pixel, switching on backlight module and regulating pixel electrode voltage of the first pixel to make transmissivity of the first pixel be decreased at the first preset time then regulating pixel electrode voltage of the second pixel to make transmissivity of the second pixel be decreased at the second preset time.

Description

technical field [0001] The invention relates to a liquid crystal display and its driving method, in particular to a color sequential liquid crystal display and its driving method. Background technique [0002] With the rapid development of imaging technology, liquid crystal displays with the characteristics of thin volume, light weight and low electromagnetic radiation have gradually become the mainstream products of displays. [0003] A color sequential liquid crystal display presents colors by successively displaying the three primary color components of a pixel. Each pixel of the color sequential liquid crystal display uses three light emitting sources which respectively emit red, green and blue light as backlight sources. During one frame time, these sub-pixels display three kinds of data sequentially, and turn on red, green and blue lights correspondingly. Using the persistence of vision of the human eye, a human can recognize the color of the pixel. [0004] However...
