Shift register unit, driving method thereof and display device

A shift register unit, comprising:

• an input module, connected to a trigger signal terminal, a pull-down signal terminal, a first clock signal terminal, a low level terminal and a pull-up control node, and configured to transmit a signal of the trigger signal terminal or a signal of the low level terminal to the pull-up control node under control of the signal of the trigger signal terminal, a signal of the first clock signal terminal and a signal of the pull-down signal terminal;
• a pull-down compensation module, connected to a control signal terminal, the pull-up control node, a pull-down control node and the low level terminal, and configured to pull down a signal of the pull-down control node at least twice when a signal of the pull-up control node is in a high-level state to pull down the signal of the pull-down control node to a low-level state;
• a pull-up module, connected to a second clock signal terminal, the pull-up control node and an output terminal of the shift register unit, and configured to pull up a signal of the output terminal of the shift register unit to the high-level state and pull up the signal of the pull-up control node to the high-level state by its own bootstrap phenomenon under control of the signal of the pull-up control node and a signal of the second clock signal terminal;
• and
• a pull-down module, connected to the input module, the pull-up module, the pull-up control node, the pull-down control node, the low level terminal and the output terminal of the shift register unit, and configured to pull down the signal of the output terminal of the shift register to the low-level state under control of the signal of the pull-down control node,
• wherein the pull-up control node is a connection node of the input module, the pull-down compensation module, the pull-up module and the pull-down module, and the pull-down control node is a connection node of the pull-down compensation module and the pull-down module.
