Abstract

The invention provides an organic light emitting display device and a method of driving the same. The organic light emitting display device comprises 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2015-0095956 filed with the Korean Intellectual Property Office on Jul. 6, 2015, the entire contents of which are hereby incorporated by reference in their entirety. technical field [0003] Embodiments of the present invention generally relate to organic light emitting display devices. More specifically, embodiments of the present invention relate to an organic light emitting display device having a dimming capability and a method of driving the organic light emitting display device.
