Abstract: A pixel compensation module according to one embodiment of the present disclosure detects a degraded region with reference to degradation data corresponding to each of pixels included in a display panel, determines a first compensation gain so as to decrease final compensation data of pixels included in the degraded region, and determines a second compensation gain so as to increase final compensation data of pixels included in an adjacent degraded region to correct compensation data of the pixels.

Abstract: An organic light emitting display (OLED) device may include a display panel, a gate driver, a data driver, a timing controller and a deterioration compensation unit. The deterioration compensator may detect one or more deteriorated regions in the display region based on stress data of the respective pixels, the stress data being generated by counting input data corresponding to the respective pixels, and generate compensation data of pixels included in each of the deteriorated regions, based on the stress data of the respective pixels and sensing data for deteriorations of pixels included in two or more horizontal lines which are arbitrarily selected among horizontal lines corresponding to the deteriorated region.
