Abstract
A display apparatus includes a display panel for displaying an image and that includes a plurality of display areas, a light source part for providing a light to the display panel, a luminance measurer for measuring a luminance of each display area of the display panel and outputting a panel luminance signal of each display area of the display panel, and a light source driver for driving the light source part based on the panel luminance signal to decrease the light source luminance signal of each display area of the display panel when the panel luminance signal of each display area of the display panel increases and to increase the light source luminance signal of each display area of the display panel when the panel luminance signal of each display area of the display panel decreases.
