Claim Text:
1. A pixel, comprising: 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 magnitude of a current that flows from the first power supply to a second power supply through the OLED in response to a magnitude of a voltage applied to the first node; a second transistor directly 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, wherein a data voltage from the data line is supplied to the first electrode of the first transistor through the second transistor.
