Abstract: A display device includes a display panel which displays an image, and a panel driving block which receives a control signal and generating a criterion point signal including information about a criterion point for adjusting luminance of the image based on the control signal. The panel driving block receives image signals, generates a correction value based on distance information about a location of the display panel, at which each of the image signals is displayed, and the criterion point, and generates correction image signals by converting the image signals based on the correction value.

Abstract: A display apparatus includes a display panel, an afterimage compensator and a data driver. The display panel displays an image. The afterimage compensator writes first stress data of input image data corresponding to a first area to a first memory area in a first block size and second stress data of the input image data corresponding to a second area to a second memory area in a second block size different from the first block size and compensates a grayscale value of the input image data based on the first stress data and the second stress data. The data driver generates a data voltage based on a compensated grayscale value and outputs the data voltage to the display panel.
