DISPLAY APPARATUS AND METHOD OF ADJUSTING BRIGHTNESS FOR THE SAME

摘要

A display device and a method for controlling brightness of the same are provided to improve a contrast ratio of a screen by removing an artifact. A display device includes a panel unit(500), a light emitting unit(400), a light emitting controller(200), and a panel controller(300). The panel unit displays an image signal. The light emitting unit provides light to the panel unit, so that the image signal is visualized. The light emitting controller controls the light emitting unit, so that the light is supplied to small sections of the panel unit. The panel controller compensates for pixel values in the image signal in respective sections, so that artifacts are removed from the small sections of the panel unit.
