Abstract
Disclosed is an organic light emitting display including: a display panel having a plurality of pixels arranged thereon; a degradation reduction circuit configured to detect a highly luminous still image pattern by analyzing input image data, and change a correlated color temperature (CCT) of a vulnerable color having the shortest lifespan in still image data corresponding to pixels displaying the highly luminous still image pattern so as to modulate the input image data into a degradation reduced data; and a display panel driving circuit configured to provide an analog data voltage, corresponding to the degradation.
