P-14: AM-OLED Pixel Circuits Based on a-InGaZnOThin Film Transistors

In this paper, we investigated the application of amorphous In-Ga-Zn-O (a-InGaZnO) thin film transistors (TFTs) to active-matrix organic light emitting display (AM-OLED) pixel circuits. SPICE model of a-InGaZnO TFTs was developed based on experimental data. Several pixel circuits were explored, and the potential advantages of using a-InGaZnO TFTs were discussed.
