Patent ID: 7382340

Claim:
A pixel circuit coupled to a first scan line for applying a first signal, a second scan line for applying a second signal, and a data line for applying a data voltage, the pixel circuit comprising: a driving transistor including a control electrode, a first electrode coupled to a first power source, and a second electrode and for outputting a current corresponding to a voltage between the first electrode and the control electrode; a display element coupled to the second electrode of the driving transistor and for displaying an image corresponding to the current output from the driving transistor; a first switching transistor coupled between the control electrode of the driving transistor and the display element; a compensation device for electrically coupling the control electrode of the driving transistor to a second power source in response to the first signal; a storage capacitor coupled between the first power source and the compensation device; and a second switching transistor for applying the data voltage to the compensation device in response to the second signal.
