Abstract:
1. A pixel of an organic light emitting display comprising a first power source, a second power source, an initialization power source, a data line, a first scan line, a second scan line, and an emission control line, the pixel comprising: an organic light emitting diode having a cathode electrode coupled to the second power source; a second transistor coupled to the data line and the first scan line, the second transistor being configured to turn on when a scan signal is supplied to the first scan line; a first transistor coupled between a second electrode of the second transistor and an anode electrode of the organic light emitting diode, the first transistor being configured to control an amount of current supplied to the organic light emitting diode; a third transistor coupled between a gate electrode and a second electrode of the first transistor, the third transistor being configured to turn on when the scan signal is supplied to the first scan line; a fourth transistor coupled between the gate electrode of the first transistor and the initialization power source, the fourth transistor being configured to turn on when the scan signal is supplied to a second scan line; a fifth transistor coupled between a first electrode of the first transistor and the first power source, the fifth transistor being configured to turn off when an emission control signal is supplied to the emission control line; a first capacitor coupled between the gate electrode of the first transistor and the first power source; and a second capacitor coupled between the gate electrode and the first electrode of the first transistor.
