Abstract: The present disclosure provides a display device with a display panel and driver. The driver includes a logo compensator to generate a logo map data with respect to a logo area through which the logo image is displayed and compensates for a brightness of the logo area using the logo map data. The logo compensator includes an extractor, a logo calculator, a logo determination unit, and a brightness compensation block. The extractor extracts logo area data. The logo calculator calculates the logo map data with first data corresponding to a first image recognized as the logo image and second data corresponding to a second image recognized as a logo background image. The logo determination unit sets a boundary area and determining whether a first area corresponding to the first image overlaps the boundary area to output determination data. The brightness compensation block compensates for the brightness of the logo area.

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.
