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.

Abstract: A light source apparatus includes a light source and a light source driver. The light source includes a plurality of scan blocks. Each scan block includes a plurality of local dimming blocks. The light source driver includes a plurality of channels configured to output light source driving signals to the plurality of local dimming blocks. The light source driving signal includes a light source intensity value representing a light intensity of a local dimming block from among the plurality of local dimming blocks and a delay value representing a degree of a delay of the local dimming block. The delay value is determined by a scan delay value varied according to the plurality of scan blocks and a delay parameter.
