Abstract: A shift register circuit and its driving method, a display panel, and a display device are provided. The shift register circuit includes an input module, a first inverter, a second inverter, and an output module. The input module is connected to a first input terminal, a second input terminal, a third input terminal, and a first electrical-level terminal, to respond to signals from the second and third input terminal and control a voltage of a first node. In the first inverter, an input terminal is connected to the first node, and an output terminal is connected to a second node. In the second inverter, an input terminal is connected to the second node, and an output terminal is connected to the first node. The output module provides a signal of the fourth input terminal to an output terminal of the output module, and also provides a voltage of a first power terminal to the output terminal of the output module.
