Abstract
An organic light emitting display device including a power generator for sending a plurality of voltages to a display unit. The display unit receives a scan signal, a light emitting control signal, and a data signal, which enable a current corresponding to the data signal to flow from a first power supply to a second power supply. The display unit includes a pixel circuit that includes a storage capacitor adapted to store the data signal and to stabilize the stored data signal utilizing a third power supply. A driver IC includes a signal generator for generating the data signal, the scan signal, and the light emitting control signal, and further includes a power generator for generating the first power, the second power, and the third power, wherein the second power and the third power are at a lower voltage than that of the first power.
