A low power TG a-IGZO TFT gate driver circuit for AMOLED display

A amorphous-indium-gallium-zinc-oxide (a-IGZO) TFT integrated 9T2C gate driver on array (GOA) circuit with a novel inverter structure has been proposed. This inverter contributes significant to the reduction of power than traditional inverter structure. To testify the function, the circuit was placed in an active-matrix organic light-emitting diode (AMOLED) display. After the panel was tape out, the circuit exhibited stable out-put signals.
