Claim 12:
13. A method for driving an electroluminescent display device including a plurality of pixels emitting light according to image data, the method comprising;
storing a first stress accumulation value corresponding to the image data in a first memory, the first stress accumulation value being an accumulation of stress values indicative of predicted deterioration amounts of the pixels corresponding to gray scales of the image data;
increasing a compensation gain for compensating for the image data on the basis of the stress accumulation value; and
resetting the first stress accumulation value in the first memory to a second stress accumulation value that is less than the first stress accumulation value and removing the first stress accumulation value in the first memory in response to increase of the compensation gain.
