Abstract
Provided are a GOA unit and driving method, a GOA circuit and a display apparatus. A first node control unit () pulls a first node (PU) to a voltage at a first level terminal (CN) under the control of a first input terminal (IN), or to a voltage at a second level terminal (CNB) under the control of a second input terminal (INPUT). A second node control unit () pulls a second node (PD) to a voltage at a third level terminal (VGH) under the control of the first level terminal (CN), the second level terminal (CNB), a second clock signal terminal (CK) and a third clock signal terminal (CK), or to a voltage at a fourth level terminal (VGL) under the control of the first node (PU). An output unit () outputs a signal at the first clock signal terminal (CK) under the control of the first node (PU), or pulls the output terminal (OUTPUT) to the voltage at the fourth level terminal (VGL) under the control of the second node (PD).
