Abstract
An organic light-emitting device and an organic light-emitting display having the same are provided. The organic light-emitting device comprises: an organic light-emitting diode emitting light using an output current; a storage capacitor for receiving a data voltage from a data line, and storing 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 one terminal of the storage capacitor; a first switching unit connected between the one terminal of the storage capacitor and the data line and having a gate connected with a first scan line; a second switching unit connected between the other terminal of the storage capacitor and an initialization voltage line and having a gate connected with the first scan line; and a third switching unit connected between the other terminal of the storage capacitor and the data line and having a gate connected with a second scan line.
