Abstract

An Amorphous In-Ga-Zn-O TFT (a-IGZO TFTs) Current-Scaling Pixel Circuit for Active Matrix Organic Light-emitting Displays (AMOLEDs) is presented, it composes of four amorphous a-IGZO TFTs and one capacitor (4T-1C), which effectively compensates the threshold-voltage-shift ( Vth 1V) of the drive TFT as well as degradation of the OLED. In a monochromatic 2-inches QVGA AMOLED display, simulating results show that programming current between several pA and hundreds of nA can realize OLED luminance from 1cd/m2 to 200cd/m2, and the aperture ratio of AMOLED with this pixel driving circuit is high as 80%.
