• a display panel comprising a display area in which an image comprising a first image and a second image is displayed;
• and
• a driver which receives external image signals and transmits data signals to the display panel, the driver comprising an image sticking compensator that converts the external image signals such that the first image is periodically shifted while being displayed, the image sticking compensator comprising:
• an extractor which extracts compensation area data corresponding to a compensation area of the display panel from the external image signals;
• a calculator which receives the compensation area data from the extractor and calculates fixed data based on the compensation area data;
• and
• a shifter which receives the fixed data from the calculator and generates shift-fixed data based on the fixed data,
• wherein the compensation area comprises a first area in which the first image is displayed and a second area in which a peripheral image included in the second image is displayed, the peripheral image at least partially surrounds the first image, and the fixed data corresponds to the first image.
