Abstract
A display device includes a display panel and a panel driving block that controls driving of the display panel. The panel driving block includes a dithering judgment block, a memory, and a dithering compensation block. The dithering judgment block determines whether a first sub-image signal corresponding to a first image requiring dithering is included in the input image signal. The dithering compensation block reads out dithering patterns, which correspond to the first sub-image signal, from among the plurality of dithering patterns from the memory, generates a compensation dithering pattern by the read dithering patterns and a random number table, and outputs a correction image signal through the first sub-image signal and the compensation dithering pattern. The first image is displayed in a stain area, and the stain area includes at least one unit area.
