1. An electroluminescent display device, comprising:
a display panel including a plurality of pixels emitting light according to image data;
a first memory storing a first stress accumulation value corresponding to the image data, 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; and
a compensation gain calculation circuit configured to increase a compensation gain for compensating for the image data on the basis of the first stress accumulation value,
wherein the first stress accumulation value in the first memory is reset to a second stress accumulation value that is less than the first stress accumulation value and the first stress accumulation value is removed from the first memory in response to increase of the compensation gain.
