Abstract: A pixel of an organic light emitting display device includes a first capacitor, second capacitor, and a number of transistors. The first capacitor stores an emission data voltage from a data line. The second capacitor stores a scan data voltage from the data line. A switching transistor is selectively turned on or off in response to the scan data voltage stored in the second capacitor. When the switching transistor and the driving transistor are turned on, an organic light emitting diode is driven to display an image.
