摘要

The increased component of the threshold voltage (Vth) of the driving transistor in an amorphous silicon TFT of 0LED (Organic Light Emitting Diode) is removed by turning on and off the gate voltage and the drain voltage at the same time. Specifically, OLED display 10 when turning on and off the gate voltage to the gate electrode of the driving circuit, and an amorphous silicon TFT that drives the OLED by an amorphous silicon TFT, supply to the drain electrode of the amorphous silicon TFT and a supply line driver 14 to the off-voltage.
