Shift register unit and gate driving circuit

A shift register unit comprising an input unit, an output unit, a pull-up unit, a pull-down control unit and a pull-down unit;

• wherein
• the input unit is connected to an input signal terminal and is configured to supply an input signal to the output unit via a first node in response to the input signal, wherein the first node functions as a connection point between the input unit and the output unit;
• the output unit is configured to supply a first clock signal to an output terminal in response to a voltage at the first node;
• the pull-up unit is configured to supply the first clock signal to the first node in response to the voltage at the first node;
• the pull-down control unit is configured to supply the first clock signal and a second clock signal to the pull-down unit via a second node as an output terminal of the pull-down control unit in response to the first clock signal and the second clock signal;
• and is configured to supply a negative voltage of a power supply to the second node in response to the voltage at the first node, wherein the second node functions as a connection point between the pull-down control unit and the pull-down unit;
• and
• the pull-down unit is configured to supply the negative voltage of the power supply to the first node and the output terminal in response to a voltage at the second node.
