Abstract: An afterimage analyzer may include an accumulation determiner which determines an accumulation interval of images based on a first change amount of images in regions of interest of the images in which an afterimage object is disposed and a second change amount of images in entire regions, an image accumulator which accumulates the images during the accumulation interval to generate accumulated images, and an afterimage object detector which detects the afterimage object from the accumulated images.

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.
