1. An organic light-emitting display device, comprising:
a display unit comprising a plurality of pixels each having an organic light-emitting diode (OLED);
a controller configured to accumulate image data of each frame and to generate compensated image data using a degradation compensation method determined, based on the accumulated image data, to compensate for the degradation of the OLED of each of the pixels; and
a data driver configured to generate a data voltage according to the compensated image data and to provide the data voltage to the pixels,
wherein the controller is configured to determine at least one of a first compensation method and a second compensation method as the degradation compensation method based on the accumulated image data,
wherein the first compensation method uses sensing data corresponding to a degree of the degradation of the OLED of each of the pixels, and the second compensation method uses the accumulated image data, and
wherein the controller is configured to determine both the first and second compensation methods as the degradation compensation method in response to the accumulated image data being greater than first reference data and less than second reference data.
