Abstract
A display apparatus and a method for adjusting brightness thereof are provided. The display apparatus includes a panel unit which displays a video signal, a light emitting unit which provides the panel unit with a ray of light and causes the video signal to be visualized, a light emission control unit which controls the light emitting unit so that the ray of light is provided to each of local areas of the panel unit, and a panel control unit which compensates pixels of the video signal in each of local areas, to remove an artifact which is generated due to the ray of light provided to local areas of the panel unit. Because brightness of a screen is adjusted in each of local areas, contrast ratio is enhanced, and improved image quality is provided.
