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 9):
An LCD device, comprising:\n a display panel; a backlight module configured to provide backlight to the display panel; wherein the backlight module is divided into a plurality of backlight subareas; a driving element connected to the display panel and configured to display each picture with two frame images sequentially; wherein the two frame images comprise 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 for each of the sub-pixels in the first frame image and the second frame image are different; a backlight control element connected to the driving element and comprising one or more processors, and memory storing instructions, which, when executed by the one or more processors cause the one or more processors to perform operations comprising: determining backlight brightness regulation signals for each of the backlight subareas according to the driving voltages of a first frame image area and a second frame image area, wherein the first frame image area and the second frame image are corresponding to each of the backlight subareas; wherein 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; and calculating an average color chroma of a current picture region corresponding to each of the backlight subareas, and determining whether the average color chroma of each of the backlight subareas is within a preset range; and a backlight regulation element connected to the backlight control element and the backlight module respectively; wherein the backlight regulation element is configured to perform 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 when the average color chroma of the backlight subarea is determined by the backlight control element to be in the preset range.
