Abstract:
A self light-emitting display unit comprising:an A/D converter for sampling a video signal to convert said video signal to pixel data corresponding to individual pixels of said self light-emitting display unit;a dithering circuit for acquiring, as dithered pixel data, upper bits of each of dither-added pixel data obtained by adding first and second sets of dither coefficients to said pixel data corresponding to a plurality of adjacent pixels on a screen of said self light-emitting display unit;a pseudo outline compensation data converter for converting said dithered pixel data based on a first conversion table and a second conversion table to yield pseudo outline compensation pixel data; anddrive means for driving individual pixels of said self light-emitting display unit for light emission based on said pseudo outline compensation pixel data,wherein said dithering circuit changes said dither coefficients to be added to said pixel data corresponding to individual pixels for each field of said video signal, and wherein said pseudo outline compensation data converter uses said first conversion table for converting said dithered pixel data acquired by using said dither-added pixel data obtained by adding said first set of dither coefficients and uses said second conversion table for converting said dithered pixel data acquired by using said dither-added pixel data obtained by adding said second set of dither coefficients.
