Claim 9:
10. A controller for a display device including a pixel unit including first pixels disposed in a first pixel area and second pixels disposed in a second pixel area, the controller comprising:
a first circuit 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; and
a second circuit configured to supply data signals to the pixel unit based on a corrected first image data and second image data corresponding to the second pixel area,
wherein:
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.
