Display device and method of driving the same

A display device comprising:

• 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 stores second cumulative data and the lifespan data;
• and
• a panel driver which provides data signals corresponding to the lifespan compensation data to the display panel to drive the display panel,
• wherein the image sticking compensator comprises:
• a compensator which receives 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, and generates the second cumulative data based on the first cumulative data;
• a memory controller which receives the second cumulative data and the lifespan data from the compensator, wherein the compensator receives the first cumulative data from the memory controller;
• a volatile memory which receives the second cumulative data from the memory controller and stores the received second cumulative data;
• a main nonvolatile memory which receives the second cumulative data from the memory controller and stores the received second cumulative data;
• and
• a sub-nonvolatile memory which receives the lifespan data from the memory controller and stores the received lifespan data.
