Abstract
A pixel of a simplified configuration, and an organic light emitting display using the same are disclosed. The pixel includes an organic light emitting diode; a first transistor connected with a scan line and a data line and turned on when a scan signal is supplied to the scan lines; a storage capacitor having one terminal connected to an electrode of the first transistor and the other terminal connected to a reset line; and a second transistor for controlling an electric current that flows from a first power source to a second power source through the organic light emitting diode according to a voltage charged in the storage capacitor, wherein the second transistor is turned-off when a reset signal is supplied to the reset line.
