Title: LIQUID CRYSTAL DISPLAY DEVICE AND DRIVING METHOD THEREFOR
Abstract:
A method for driving a liquid crystal display device, comprising: displaying each picture by two frames of images in order (S110), two adjacent sub-pixels on each frame of image being different in driving voltage, and the first frame of image and the second frame of image of each sub-pixel being different in driving voltage; determining a backlight brightness regulating signal of each backlight subarea according to driving voltages of a first frame of image area and a second frame of image area corresponding to each backlight subarea (S120), the backlight brightness regulating signals being grouped signals, and the number of groups of the signals being equal to the number of varieties of the color sub-pixels; and conducting independent brightness regulation on backlight sources of various color sub-pixels within corresponding backlight subareas of various frames of images of the next picture according to the backlight brightness regulating signal of each backlight subarea (S130).
