Abstract:
1. An organic light emitting display comprising: a plurality of scan lines adapted to transmit a scan signal; a plurality of data lines adapted to transmit a data signal; a plurality of emission control lines; and a plurality of pixels connected to the scan lines, the emission control lines, and the data lines, wherein at least one of the pixels comprises an organic light emitting diode; a driving transistor adapted to supply a driving current to the organic light emitting diode; a first switching transistor adapted to selectively supply the data signal to the driving transistor; a second switching transistor adapted to selectively supply an initialization signal; a third switching transistor adapted to selectively allow the driving transistor to be connected as a diode and to selectively supply the initialization signal; a storage capacitor adapted to store a first voltage corresponding to the initialization signal received from the third switching transistor and then to store a second voltage corresponding to the data signal applied at a gate electrode of the driving transistor; and an interrupter adapted to selectively supply a pixel power to the driving transistor and to selectively allow the driving current to flow into the organic light emitting diode.
