Abstract: A display device includes a display panel which displays an image, an image sticking compensator which receives image data, compensates for the image data based on lifespan data to generate lifespan compensation data, and a panel driver which provides data signals corresponding to the lifespan compensation data to the display panel. The image sticking compensator includes a compensator which receives the first cumulative data, generates the lifespan data based on the first cumulative data, compensates for the image data based on the lifespan data to generate the lifespan compensation data, a memory controller which receives the second cumulative data and the lifespan data from the compensator, a volatile memory which stores the second cumulative data from the memory controller, a main nonvolatile memory which stores the second cumulative data from the memory controller, and a sub-nonvolatile memory which stores the lifespan data from the memory controller.
