Abstract
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.
Claims14
A shift register unit, comprising:
- a latch module having a first voltage terminal, a second voltage terminal, a first clock signal terminal, an input terminal and an output terminal, the latch module being provided with a latch function;
- and
- a latch output module having a first voltage terminal, a second clock signal terminal, a control terminal and a same-stage signal output terminal, the first voltage terminal of the latch output module being connected with the first voltage terminal of the latch module, the control terminal of the latch output module being connected with the output terminal of the latch module;
- wherein the latch module is used for controlling switching on and off of the latch function and the latch output module depending on a signal inputted via the input terminal of the latch module and a signal inputted via the first clock signal terminal;
- and
- wherein the latch output module is used for outputting a signal inputted via the second clock signal terminal to the same-stage signal output terminal when the latch output module is switched on, and for isolating the signal inputted via the second clock signal terminal when the latch output module is switched off.
