Shift register, gate drive circuit and its driving method, display panel

This application relates to a shift register, a gate driving circuit and its driving method, and a display panel. The shift register includes: an input module; a control module including a first switching unit, a second switching unit, and an energy storage unit, wherein the control terminal of the first switching unit receives a first control signal, the second terminal of the first switching unit is electrically connected to the first terminal of the energy storage unit and the second terminal of the second switching unit, the control terminal of the second switching unit receives a second control signal, and the first terminal of the second switching unit receives a second power supply signal; and an output module; in a first sub-stage of the holding phase, the first switching unit is turned off under the control of the first control signal, and the second switching unit is turned on under the control of the second control signal, so that the voltage levels of the first terminal and the third terminal of the energy storage unit remain consistent. Using the above-mentioned shift register, the energy storage unit can be controlled to not charge or discharge in the first sub-stage, thereby reducing power consumption.
