Abstract
An organic light emitting display device includes pixel driving circuits to control pixels which include organic light emitting diodes. The pixel driving circuits include a first pixel driving circuit and a second pixel driving circuit, and the organic light emitting diodes include a first organic light emitting diode. The first organic light emitting diode emits light at a first brightness based on a driving current from the first pixel driving circuit in a first frame, and emits light at a second brightness based on a driving current from the second pixel driving circuit in a second frame.
