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 5):
The method for  claim 4 , wherein in the step of calculating the backlight brightness regulation signal according to the average driving voltage, the reference backlight brightness signal and the reference driving voltage, the formulas to calculate the backlight brightness regulation signal of each of the color sub-pixels in each of the backlight subareas are:\n A M_P1 *P M_ave1 =A M_P2 *P M_ave2 ; 2 *A M_P *P M_ave =A M_P1 *P M_ave1 +A M_P2 *P M_ave2 ; wherein P is a target color sub-pixel; M is a serial number of the backlight subarea, A M_P1  is the backlight brightness regulation signal to perform the backlight brightness regulation to the backlight source of a P sub-pixel in a backlight subarea M corresponding to the first frame image of the next picture; A M_P2  is the backlight brightness regulation signal to perform a backlight brightness regulation to the backlight source of the P sub-pixel in the backlight subarea M corresponding to the second frame image of the next picture; P M_ave1  is P an average value of the driving voltage of the P sub-pixel in the backlight subarea M corresponding to the first frame image of the current picture; P M_ave2  is an average value of the driving voltage of the P sub-pixel in the backlight subarea M corresponding to the second frame image of the current picture; A M_P  is the reference backlight brightness signal of the P sub-pixel in the backlight subarea M corresponding to the image of the current picture; P M_ave  is the average value of the reference driving voltage of the P sub-pixel in the frame image area corresponding to the backlight subarea M on the image of the current picture.
