Abstract: There is provided an organic light emitting display device including a display panel including pixels and a display panel driver configured to drive the display panel. The display panel driver is arranged to receive a maximum brightness signal. When a maximum brightness determined corresponding to the maximum brightness signal is lower than a first reference maximum brightness for a frame, the display panel driver is programmed to direct less than all of the pixels to emit light components during a frame period of the frame. When the maximum brightness is higher than the first reference maximum brightness and is lower than a second reference maximum brightness, the display panel driver is programmed to direct all of the pixels to emit light components during only part of the frame period. The second reference maximum brightness is higher than the first reference maximum brightness.
