A GOA Circuit Capable of Simultaneously Outputting Positive and Negative Pulses

A new gate driver circuit composed of amorphous In-Ga-Zn-O (a-IGZO) thin-film transistors (TFTs) is proposed. Through this circuit we can output both positive and negative pulse waveforms. Positive pulses can be used to normally drive the panel to emit light, and negative pulses can be used to implement the internal compensation function. Through simulation we found that the circuit has a very large margin (9 V to 11V).
