Abstract: Disclosed are a GOA drive unit and a GOA drive circuit. The GOA drive unit includes a bidirectional selection unit. The bidirectional selection unit is activated under an action of a first control signal and a second control signal which are complementary to each other in timing sequence, and outputs a first selection signal. The bidirectional selection unit is activated under an action of a third control signal and a fourth control signal which are complementary to each other in timing sequence, and outputs a second selection signal. The GOA drive unit can reduce the influence of stress and improve the reliability of the GOA drive circuit.
