ORGANIC LIGHT EMITTING DISPLAY DEVICE AND DRIVING METHOD FOR THE SAME

摘要

PURPOSE: An organic light emitting display device and driving method for the same are provided to increase the usage time of a battery by making the operation range of a driving power source wider. CONSTITUTION: A pixel unit(100) displays an image. A data driver(200) transmits an image signal. A data driver outputs a data signal. A scan driver(300) outputs a scanning signal. A power supply unit(500) generates a first power source and a second power source. A controller(400) outputs a voltage control signal and a first gamma or a second gamma. The voltage control signal outputs the voltage of a second power source and a first power source. The first gamma or the second controls the voltage of a data signal.
