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.

Abstract: A display device may include a display panel, a data driver transmitting a data signal, a scan driver sequentially transmitting a scan signal, a frequency selector for selecting a driving frequency for image display, selecting a low frequency if the image displayed on the display panel is a first image and selecting a normal frequency if the image displayed on the display panel is not the first image, the normal frequency being higher than the low frequency. The display device also includes a timing controller for controlling the data driver and the scan driver based on the selected driving frequency. The timing controller may control the data driver and the scan driver such that luminance of the display panel on which the first image is displayed is periodically changed according to the low frequency if the image displayed on the display panel is the first image.
