Abstract:
A method for driving an LCD device includes displaying each picture with two frame images sequentially; the two frame images includes a first frame image and a second frame image; driving voltages for two adjacent sub-pixels in each of the frame images are different, and driving voltages in the first frame image and the second frame image for each of the sub-pixels are different; determining backlight brightness regulation signals for each of the backlight subareas; the backlight 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 purity of a current picture area corresponding to each backlight subarea; determining whether the average color purity 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 9):
The LCD device of  claim 7 , wherein the backlight compensation control part comprises a memory and one or more processors; the memory has stored computer executable instructions that are executable by the at least one memory, when a computer executable instruction is being executed by the one or more processors such that the steps in the following units are executed:\n a statistic unit configured to calculate average driving voltages for various color sub-pixels in the first frame image area and the second frame image area, wherein the first frame image area and the second frame image are corresponding to each of the backlight subareas; and a calculation unit configured to calculate the backlight brightness regulation signal according to the average driving voltage, a reference backlight brightness signal and a reference driving voltage of each of the backlight subareas.
