Abstract
An organic light emitting display device includes: an APL calculation unit; a current value calculation unit output a first result value or output a second result value; a peak luminance controller configured to output a first luminance control signal based on a first gamma conversion value when receiving the first result value from the current value calculation unit and output a second luminance control signal based on a second gamma conversion value when receiving the second value from the current value calculation unit; a programmable gamma unit configured to output a gamma voltage; and a data driver configured to generate a data signal and supply the generated data signal to a display panel.
