ABSTRACT:
An organic LED (OLED) display device and an operating method of driving the same. In an OLED image display device, one switch transistor is provided in one pixel. For at least a part of an OFF period of time of the switch transistor, the OLED is in the non-light emission state, and also the bias of the polarity reverse to that in the light emission is applied to the OLED.
