Abstract
In an organic light emitting display including a pixel, and a method of driving the same, the pixel includes an organic light emitting diode (OLED), a storage capacitor coupled between a first power supply and a first node, a first transistor for controlling a current that flows from the first power supply to a second power supply through the OLED in response to a voltage applied to the first node, a second transistor coupled between a data line and a first electrode of the first transistor and turned on when a control signal is supplied through a control line, a third transistor coupled between the first node and a second electrode of the first transistor and turned on when a scan signal is supplied through an nth (n is a natural number) scan line, and a fourth transistor coupled between an initializing power supply and the first node and turned on when the scan signal is supplied through an (n−1)th scan line.
