Abstract

A display device includes a display panel, a memory, a dithering processor, and a panel driver. The display panel includes a display surface, and the memory stores dither patterns with respect to at least one spot area included in the display surface. The dithering processor selects a dither pattern among the dither patterns in a predetermined time unit and outputs a compensation image signal corresponding to the dither pattern. The panel driver outputs a data signal corresponding to the spot area based on the compensation image signal. Each of the dither patterns includes a first grayscale area having a first grayscale value higher than a first target grayscale value of the spot area and a second grayscale area having a second grayscale value lower than the first target grayscale value.
