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.
