A stable pixel circuit with constant current compensation for threshold voltage, mobility, and subthreshold swing variations

Abstract In this paper, we propose a novel active matrix organic light-emitting diode (AMOLED) pixel circuit using amorphous indium-gallium-zinc oxide (a-IGZO) thin-film transistors (TFTs). The proposed pixel circuit, which comprises seven TFTs and two capacitors, is capable of comprehensively and s...
