The a‐IGZO TFTs integrated gate driver being compatible depletion‐mode device is proposed for AMOLEDs. The circuit features a bootstrapping inverter, which is initialized by global signal and controlled by cascading gate‐driving signals. Two sets of clocks with different low voltages are employed. Enhanced stability and reduced power consumption is thus resulted. The circuit can generate ultra‐wide compensation signals for AMOLED displays even with V th of ‐6 V.
