Abstract

The invention discloses an image drive method and a system as well as a liquid crystal display (LCD); wherein, the image drive method comprises the following steps: an overdrive operation for a pixel of a piece of primary color on a flat-panel display is implemented, a plurality of overdrive corresponding tables are provided to different primary colors, and the periods of the response time of the light-transmitting media for transmitting the primary color lights are differentiated to eliminate the aberration due to image persistence. Furthermore, the overdrive operation can be segmented into a plurality of overdriven operations to enhance the operating effects. The method has advantage of eliminating the image persistence aberration, which is caused by the different generating periods of the primary color lights of a scanning backlight unit on the flat-panel display. The image drive system comprises an overdrive circuit module and a display unit; the LCD comprises another overdrive circuit module, a source electrode drive circuit, a grid electrode drive circuit and a thin-film transistor liquid crystal panel.

Description

technical field

[0001] The invention relates to a driving method and its system and a liquid crystal display using the same, in particular to an image driving method and its system and a liquid crystal display using the same. Background technique

[0002] The backlight modules of the existing liquid crystal flat panel display are divided into two types: hold type and scan type. The hold-on backlight module is continuously on to supply the light source for the liquid crystal display panel. This hold-on backlight module has proved to have a major disadvantage, that is, insufficient response to moving images. When a fast moving image is displayed on the screen, because the switching response time of the liquid crystal pixel unit is too slow, the image will not be converted in time, and a shadow with a lighter grayscale will appear behind the moving object, which is the so-called afterimage phenomenon.

[0003] figure 1 It is to illustrate the dynamic image response curve (MPR...
