Abstract: A display device includes a display panel and a driver which receives image signals and transmits data signals to the display panel. The driver includes an image sticking compensator that converts the image signals such that the first image is periodically shifted while being displayed. The image sticking compensator includes an extractor which extracts compensation area data corresponding to a first image displayed in a compensation area, a calculator which calculates fixed data based on the compensation area data and corresponding to the first image, and a shifter which generates shift-fixed data based on the fixed data. The compensation area includes a first area in which the first image is displayed and a second area in which a peripheral image at least partially surrounding the first image is displayed.

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.
