This work proposes a bidirectional gate driver circuit that can provide scan signals for AMOLED pixel circuits. The proposed circuit generates a stable output waveform with high driving capability and low leakage current by adopting the LTPO backplane. Hence, this circuit has great prospects for use in low-frame-rate displays.
