Abstract:
1. A pixel comprising: an organic light emitting diode; a storage capacitor having a first terminal and a second terminal; a first transistor coupled to the second terminal of the storage capacitor for supplying a current from a first power source to a second power source through the organic light emitting diode, the current corresponding to a voltage at the second terminal of the storage capacitor, the first transistor having a first electrode coupled to the first power source; a second transistor coupled between a data line and the first terminal of the storage capacitor and being controlled by a first scan signal supplied to a first scan line; a third transistor coupled between the second terminal of the storage capacitor and a second electrode of the first transistor and being controlled by the first scan signal; a fourth transistor coupled between the second electrode of the first transistor and an initialization power source and being controlled by a second scan signal supplied to a second scan line; and a fifth transistor coupled between the first terminal of the storage capacitor and the initialization power source and being controlled by an emission control signal supplied to an emission control line.
