Abstract:
1. An organic light emitting display device comprising; a scan driver for sequentially supplying scan signals to first scan lines and sequentially supplying inverse scan signals that are produced by inverting the scan signals, to second scan lines; a data driver for supplying data signals to data lines; a display unit comprising pixels located at crossing regions of the first scan lines and the data lines, each of the pixels comprising a storage capacitor; first power lines extending in parallel to the data lines and coupled between a first power supply and the pixels; at least one second power line located outside the display unit and coupled to a second power supply having a voltage different from a voltage of the first power supply; at least one third power line extending in parallel with the data lines and coupled to a third power supply having a voltage different from the voltage of the first power supply; and fourth power lines extending in the pixels are charged with voltages corresponding to the data signals and the third in parallel with the scan lines and coupled to the pixels, wherein the storage capacitors power supply and are configured to control an amount of current flowing from the first power supply in accordance with the voltages charged in the pixels, and wherein one terminal of the storage capacitors is configured to receive a voltage from the second power supply in response to the scan signals, and to receive a voltage from the third power supply in response to the inverse scan signals.
