摘要： Embodiments of the present disclosure provide a shift register unit and a driving method thereof, a gate driving circuit and a display device. The shift register unit comprises a latch module and a latch output module. Switching on and off of the transmission gates is controlled by using an intermediate signal generated based on a clock signal and an inputted signal, instead of by using the clock signal, such that the shift register unit will not be influenced by frequent flips of the clock signal in a non-operational state, thus avoiding a great deal of useless power consumption.
