Patent ID: 8619102

Claim:
A display apparatus, comprising: a panel which displays a video signal; a light emitter which provides the panel with a ray of light and causes the video signal to be visualized; a light emission controller which controls the light emitter to provide the ray of light to each of local areas of the panel in accordance with brightness values of the corresponding areas of the video signal; and a panel controller which compensates pixels of the video signal in each of the local areas of the panel in accordance with the brightness values of the corresponding areas of the video signal, wherein the light emission controller comprises: a local brightness adjusting unit which controls the light emitter to adjust brightness of each of the local areas of the panel by using the brightness values, and a general brightness adjusting unit which controls the light emitter to adjust overall brightness of the panel at a same ratio by adjusting the brightness of each of the local areas of the panel at the same ratio using representative values of the local areas of the panel that are computed by the local brightness adjusting unit and the compensated pixels.
