Abstract:
A display device includes: a target pixel; observation target pixels located adjacent to the target pixel; and a grayscale corrector for converting an input grayscale value corresponding to the target pixel with reference to observation target grayscale values corresponding to the observation target pixels. The grayscale corrector includes: a light emitting pixel counter for providing a number of light emitting pixels by counting a number of observation target pixels that exceeds a reference value; and a grayscale converter for providing a converted grayscale value by converting the input grayscale value, based on the number of light emitting pixels.
