Abstract
A display device includes: a memory; a pixel unit including first pixels disposed with a first density in a first area and second pixels disposed with a second density smaller than the first density in a second area in contact with the first area; and a degradation compensator which updates degradation information stored in the memory, based on input grayscales for the first and second pixels, and changes the input grayscales to output grayscales, based on the degradation information. The degradation compensator stores the degradation information in the memory in a unit of block for the pixel unit. The memory stores only first degradation information for each of first blocks including only the first pixels, stores only second degradation information for each of second blocks including only the second pixels, and stores the first and second degradation information for each of third blocks including both the first and second pixels.
