Abstract:
A method for driving an LCD device includes displaying each picture with two frame images sequentially; driving voltages for two adjacent sub-pixels in each of the frame images are different, and driving voltages for each sub-pixel in the first frame image and the second frame image are different; determining backlight brightness regulation signals for each of the backlight subareas; the backlight brightness regulation signals are grouped signals, the number of the groups is identical to the number of types of the color sub-pixels; calculating an average color chroma of a current picture region corresponding to each of the backlight subareas; determining whether the average color chroma of each of the backlight subareas is within a preset range; if yes, performing a brightness regulation to a backlight source of the backlight subarea in each of the frame images of a next picture according to the backlight brightness regulation signal of the backlight subarea.

Claim (Index 7):
The method according to  claim 1 , wherein the step of performing the brightness regulation to the backlight source of the backlight subarea in each of the frame images of the next picture according to the backlight brightness regulation signal of the backlight subarea comprises:\n calculating an average display hue of a current picture region corresponding to the backlight subarea; determining a backlight regulation object according to the hue range where the average display hue belongs; wherein the backlight regulation object comprises a backlight source of at least one of a red sub-pixel, a green sub-pixel and a blue sub-pixel; and performing an independent brightness regulation to the backlight regulation object according to the backlight brightness regulation signal corresponding to the backlight regulation object.
