Abstract:
An OLED device is disclosed. The OLED device disposes a voltage divider and a switch unit in the output stage of a power supplier, thereby lowering the level of a supply voltage VDD, which is applied to a driver IC in an emission interval, below that of the supply voltage which is applied to the driver IC in a non-emission interval. Accordingly, the OLED device can reduce electric power consumption.
