Abstract: A display device of the present disclosure comprises pixels arranged in a display, a data accumulator for accumulating first image data for an N-th frame output through the display, a data receiver for receiving second image data for an (N+1)th frame to be output through the display, and an afterimage controller for correcting a current value corresponding to a grayscale value of the second image data through a convolution operation between a filter, which is set based on the first image data, and the second image data.
