Abstract: An apparatus for detecting an afterimage candidate region includes: a comparison unit which compares gradation data of an n-th frame with integrated gradation data of an (n−1)-th frame and generates integrated gradation data of the n-th frame, where n is a natural number; a memory which provides the integrated gradation data of the (n−1)-th frame to the comparison unit and stores the integrated gradation data of the n-th frame; and an afterimage candidate region detection unit which detects an afterimage candidate region based on the integrated gradation data of the n-th frame, where each of the integrated gradation data of the n-th frame and the integrated gradation data of the (n−1)-th frame comprises a comparison region and a gradation region.

Abstract: A display device includes a display unit including a plurality of pixels, a data converter to receive grayscale values respectively corresponding to the plurality of pixels, generate first compensated grayscale values by remapping the grayscale values of a first grayscale range to the first compensated grayscale value of a second grayscale range, and generate second compensated grayscale values by compensating for the first compensated grayscale values based on first compensated grayscale values of adjacent pixels, and a data driver to generate data signals based on the second compensated grayscale values and provide the data signals to the plurality of pixels of display unit, wherein adjacent pixels of a target pixel correspond to pixels adjacent to the target pixel, and wherein at least one of the adjacent pixels emits light having a color different from that of the target pixel.
