Abstract: A display apparatus and control method thereof are provided. The display apparatus including: a display configured to display an image; a backlight unit including a plurality of light sources configured to emit light to a screen of the display; an image processor configured to divide an input image into a plurality of blocks, identify target brightness for each block, and adjust a control value of each of the plurality of light sources based on priority of each of the plurality of light sources; and a driver configured to drive the plurality of light sources based on the control value. Thus, the duty for controlling the quality of light from the light source is identified considering the duty of the light source corresponding to an area of which previously identified priority is high, and thus dimming control is possible taking effects of light diffusion from adjacent neighboring light sources into account.
