Abstract

This paper demonstrates a new driving scheme which allows reducing the supply voltage of data drivers for low power active matrix organic light emitting diode (AMOLED) displays. The proposed technique drives down the data voltage range by 50%, which subsequently diminishes in the peak power consumption of data drivers at the full white pattern by 75%. Because the gate voltage of a driving thin film transistor (TFT) covers the same range as a conventional one by means of a level-shifting scheme, the low data supply scheme achieves the equivalent dynamic range of OLED currents. The normalized power consumptions have been kept at the lower level than 0.25.
