• an acquiring unit, for acquiring a second preset parameter of each partition of the backlight relative to a second frame image, the second frame image being a previous frame image of the first frame image;
• a determining unit, for determining a grayscale compensation coefficient of the first frame image according to the first preset parameter and the second preset parameter;
• the determining unit, for determining a backlight coefficient of each partition of the first frame image;
• and
• a displaying unit, for driving the backlight according to the determined backlight coefficient of each partition and driving a display screen according to the grayscale compensation coefficient to display the first frame image.
