Shift register unit, gate driving circuit, display apparatus and control method thereof

A shift register unit, comprising:

• an input sub-circuit, having a first terminal connected to a first signal line, a second terminal connected to a pull-up node, and a third terminal connected to an input signal line;
• an output sub-circuit, having a first terminal connected to the pull-up node, a second terminal connected to a clock signal line, and a third terminal connected to an output terminal, and configured to output a clock signal inputted by the clock signal line to the output terminal under a control of the pull-up node;
• a shutdown control sub-circuit, having a first terminal connected to the output terminal, a second terminal connected to a first shutdown control signal line, and a third terminal connected to a second shutdown control signal line, wherein the shutdown control sub-circuit is configured to output a second shutdown control signal inputted by the second shutdown control signal line to the output terminal under a control of a first shutdown control signal.
