摘要： An organic electroluminescent display supplies a reverse bias voltage to an Organic Light-Emitting Diode (OLED) for emitting light. The organic electroluminescent display additionally includes a reverse bias transistor to supply the reverse bias voltage. The reverse bias transistor is connected between an anode of the OLED and a reverse bias power supply, between the anode of the OLED and a first power line supplying a positive source voltage, or between the anode of the OLED and a data line. Furthermore, the reverse bias transistor can be connected between an initialization line and the anode of the OLED. The reverse bias voltage is supplied to the OLED before displaying an image or within a non-display period of a vertical synchronous signal, thereby enabling detection of whether or not the OLED has a defect.
