Organic light-emitting diode-based display device and method for driving the device

Abstract:

Disclosed are an organic light-emitting diode-based display device and a method for controlling the device. The device may include an organic light-emitting diode-based display panel; and a data driver configured for: dividing a reference gamma voltage into a first gamma voltage corresponding to a high gray level and a second gamma voltage corresponding to a low gray level; selecting one between the first and second gamma voltage based on a gray level of video data; and supplying the selected one through a corresponding output stage among dual output stages, wherein the dual output stages respectively correspond to the first and second gamma voltages.
