Abstract
A display device includes a display panel, a dither table memory device, a dithering processor, and a display panel driver. The display panel includes a plurality of pixels. Dither tables are stored in the dither table memory device. The dithering processor selects a target dither table corresponding to a grayscale level of input data from among the plurality of dither tables and performs a dithering operation on the input data using the target dither table to generate dither data. The display panel driver drives the display panel based on the generated dither data.
