Claim 0:
1. A display device comprising:
a pixel unit including first pixels disposed in a first pixel area and second pixels disposed in a second pixel area; and
a controller configured to correct grayscales of a first image data corresponding to the first pixel area based on a dimming level defining a maximum luminance at which the pixel unit is able to emit light,
wherein:
the controller is configured to supply data signals to the pixel unit based on the corrected first image data and second image data corresponding to the second pixel area;
a luminance of the first pixel is lower than a luminance of the second pixel responding to input grayscales in a first grayscale range; and
a number of the first pixels disposed per unit area is less than a number of the second pixels disposed per unit area.
