Abstract
A GOA circuit comprises m cascaded GOA units, wherein a GOA unit comprises forward-reverse scan control module, first gate signal output module and second gate signal output module. The forward-reverse scan control module controls the GOA circuit to perform forward scanning or reverse scanning. The first gate signal output module comprises seventh TFT, ninth TFT and sixteenth TFT; a second terminal of the sixteenth TFT receives a high potential signal, and a first and a third terminal of the sixteenth TFT are connected to the first and second terminals of the seventh TFT, respectively. The second gate signal output module comprises twelfth TFT, thirteenth TFT and fifteenth TFT; a second terminal of the fifteenth TFT receives the high potential signal, and a first and a third terminal of the fifteenth TFT are connected to the first and second terminals of the twelfth TFT, respectively.
