摘要： An LCD device with an improved contrast ratio and a reduced electric power consumption and a driving method thereof are disclosed. The LCD device and the driving method thereof generate a data modulation control signal using single frame image data to be displayed on a liquid crystal panel, and then generating a plurality of modulated local dimming control signals for a plurality of divisional regions of the divided single frame image data. A modulated data, in which the single frame image data is compensated with the data modulation control signal is generated and applied to the liquid crystal panel. A plurality of driver signals each corresponding to the modulated local dimming control signals are applied to the blocks of a backlight unit. The divisional regions are opposite to the blocks, respectively.

摘要： An LCD device adapted to apply an optimized luminance in correspondence with a brightness of each divisional region of image is disclosed. The LCD device uses dimming curves, which are provided differently from each other, for divisional regions which are divided from one frame and have different pixel numbers. Therefore, the LCD device can a luminance optimized to a brightness of each divisional region of image, thereby preventing a luminance mismatching phenomenon and a luminance nullity phenomenon.
