Abstract
An organic light emitting diode (OLED) display including: a display unit including pixels; and a power supply unit including: an output terminal; a reference terminal having an insulated output; and a bias circuit generating a first power source voltage from a received input voltage and supplying a second power source voltage to the reference terminal wherein the first power source voltage and the second power source voltage are voltages driving the plurality of pixels, wherein the bias circuit supplies the second power source voltage to the reference terminal and the plurality of pixels and is referenced to a ground voltage, and wherein a current flowing to the pixels flows to the reference terminal. In the OLED display, one power supply may be used as a power supply powering electroluminescence (EL), and thereby a cost of the OLED display may be reduced and a power efficiency may be improved.
