Abstract
A display apparatus includes a local dimmer, an image compensator, a display panel and a light source. The local dimmer is configured to generate a dimming signal representing a degree of dimming for a light source block based on input image data. The image compensator is configured to determine a grayscale gain based on input grayscale value of the input image data and the dimming signal and to compensate luminance of the input image data based on the grayscale gain. The display panel is configured to display an image based on the compensated input image data. The light source is configured to provide light to the display panel based on the dimming signal.
