摘要 |
A liquid crystal display includes a liquid crystal display panel, a backlight unit including a plurality of light sources, the backlight unit providing light to a back surface of the liquid crystal display panel, a backlight driving circuit that individually drives a plurality of previously determined blocks each including the light sources based on a dimming value of each of the blocks, and a local dimming control circuit that calculates a pixel gain value compensating for a luminance reduction resulting from the dimming value of each block and corrects the pixel gain value based on a grayscale saturation level of each block.
