Abstract: A display device includes a compensation value determiner which generates final compensation values for an input image, a timing controller which receives input grayscales of the input image and generate output grayscales by applying the final compensation values to the input grayscales, and a pixel unit which displays an output image corresponding to the output grayscales using pixels. The compensation value determiner determines weights based on display frequencies, display brightnesses, and the input grayscales, the compensation value determiner determines compensation values based on the display frequencies and positions of the pixels, and the compensation value determiner generates the final compensation values by applying the weights to the compensation values.
