Provided is a GOA unit, comprising a first node control unit (31), a second node control unit (32) and an output unit (33), wherein the first node control unit (31) is used for pulling a level of a first node (PU) to align with a signal of a first level end (CN) under the control of a signal of a first input end (IN), or is used for pulling the level of the first node (PU) to align with a signal of a second level end (CNB) under the control of a signal of a second input end (INPUT); the second node control unit (32) is used for pulling a voltage of a second node (PD) to align with a signal of a third level end (VGH) under the control of the first level end (CN), the second level end (CNB), a second clock signal end (CK2) and a third clock signal end (CK3), or is used for pulling the voltage of the second node (PD) to align with a fourth level end (VGL) under the control of the first node (PU); and the output unit (33) is used for outputting a signal of a first clock signal end (CK1) at an output end (OUTPUT) under the control of the first node (PU), or is used for pulling a level of the output end (OUTPUT) to align with the fourth level end (VGL) under the control of the second node (PD). Also provided are a GOA circuit, a display device and a GOA drive method. |
