More Information
Summary:A display device includes a mapping unit for mapping main color data having information on three main colors to generate mapped main data including red, green, and blue information and mapped white data including white information, a compensation lookup table for storing a plurality of gamma compensation values, a gamma compensator for generating compensated main data obtained by gamma-compensating the mapped main data based on a first gamma compensation value corresponding to first gamma white data from among the plurality of gamma compensation values and a second gamma compensation value corresponding to second gamma white data from among the plurality of gamma compensation values by referring to the compensation lookup table, a renderer for sub-pixel-rendering the mapped white data to generate rendered white data, and a splitter for converting the rendered white data into the first and second gamma white data based on different first and second gamma curves, respectively.
