1. An electronic device comprising:
a pixel unit including first pixels disposed in a first pixel area and second pixels disposed in a second pixel area;
a camera overlapped with the first pixel area;
a timing controller configured to provide a first image data corresponding to the first pixel area and a second image data corresponding to the second pixel area;
a controller configured to correct grayscales of the first image data based on a dimming level defining a maximum luminance at which the pixel unit is able to emit light; and
a data driver configured to supply data signals to the pixel unit based on the corrected first image data and the second image data,
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.
