Abstract: A display device includes a display panel, a controller, and a data driver. The display panel includes a plurality of pixels. The controller is configured to: receive input image data for the display panel; divide the display panel into a plurality of first pixel blocks each having a first size; divide the display panel into a plurality of second pixel blocks each having a second size different from the first size; generate, based on the input image data, a first stress map for the plurality of first pixel blocks and a second stress map for the plurality of second pixel blocks; and generate output image data by compensating the input image data based on the first stress map and the second stress map. The data driver is configured to provide data voltages to the plurality of pixels based on the output image data.

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: 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.
