1. A display panel, comprising a shift register unit, the shift register unit comprising a shift register, an inverter and a line drive signal enhancement circuit,
wherein the line drive signal enhancement circuit comprises:
a control unit, having a first control terminal and a second control terminal, for inputting a first power supply voltage to one of a first node and a second node, and inputting a second power supply voltage to the other of the first node and the second node, under the control of the first control terminal and the second control terminal;
wherein the shift register is used for outputting an initial scan signal to an input terminal of the inverter and the first control terminal of the line drive signal enhancement circuit; and an output terminal of the inverter is connected to the second control terminal of the line drive signal enhancement circuit.
