Patent ID: 7561129

Claim:
An organic light-emitting device comprising: an organic light-emitting diode emitting light using an output current; a storage capacitor that receives a data voltage from a data line and stores the received data voltage; a driving thin film transistor connected between a source voltage and the organic light-emitting diode and having a gate connected to a first terminal of the storage capacitor to supply the output current to the organic light-emitting diode using the data voltage stored in the storage capacitor; a first switching unit connected between the first terminal of the storage capacitor and the data line, the first switching unit having a control terminal connected with a first scan line to receive an input current from the data line by a first scan signal and transmit a control terminal voltage of the driving thin film transistor to the first terminal of the storage capacitor; a second switching unit connected between a second terminal of the storage capacitor and an initialization voltage line and having a control terminal connected with the first scan line to transmit an initialization voltage to the second terminal of the storage capacitor by the first scan signal; and a third switching unit connected between the second terminal of the storage capacitor and the data line and having a control terminal connected with a second scan line to transmit the data voltage to the second terminal of the storage capacitor through the second scan line.
