Patent ID: 7477218

Claim:
A pixel circuit, comprising: a selection transistor having one end connected to a data line, and a control end receiving a selection signal; a correction transistor having one end connected to the other end of the selection transistor, and a control end connected to a first power source at a predetermined voltage; a driving transistor having a control end connected to the other end of the correction transistor, and one end connected to a second power source functioning as a current supply source; a storage capacitor having one end connected to the control end of the driving transistor, and the other end connected to a pulse voltage line; and an emissive element for emitting light caused by a current flowing through the driving transistor, wherein the correction transistor is switched between on and off states in a process of turning on the driving transistor by changing a voltage value of the pulse voltage line, thereby controlling a voltage of the control end of the driving transistor when it is turned on, and the driving transistor and the correction transistor are formed adjacent to each other, wherein a data voltage for turning on the correction transistor is supplied to the data line while the selection transistor is ON, a voltage corresponding to the data voltage is stored at the control end of the driving transistor, the selection transistor is turned off thereafter, and the voltage of the control end of the driving transistor is shifted by changing the voltage of the pulse voltage line in this state, thereby turning off the correction transistor and turning on the driving transistor to cause a current in accordance with the data voltage to flow into the driving transistor.
