Abstract: According to an embodiment of the present disclosure, a method for controlling a display device includes inputting frame data for each frame input period of a vertical synchronization signal, accumulating stress data for some pixels in predetermined accumulation units based on the frame data for each blank period of the vertical synchronization signal, accumulating an input time of the frame data, calculating a correction gain value for correcting the accumulated stress data based on the input time accumulated when the accumulation of the stress data is completed for all pixels, correcting the accumulated stress data based on the correction gain value, and storing the corrected accumulated stress data.

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.
