Abstract
Disclosed is a GOA drive unit and drive circuit. The GOA drive unit includes a first pull-down transistor, a second pull-down transistor, a third pull-down transistor, a fourth pull-down transistor, a fifth pull-down transistor that is configured to maintain a low voltage at gate electrodes of the first pull-down transistor and the third pull-down transistor, and a sixth pull-down transistor that is configured to maintain a low voltage at gate electrodes of the second pull-down transistor and the fourth pull-down transistor. The drive unit can reliably stabilize a voltage on a critical circuit node in a circuit.
