Shift register unit, gate drive device, display device, and control method

A shift register unit, comprising:

• an input module, connected with a driving input signal input terminal, a clock signal input terminal, and a pull-up control node, and configured to control potential of the pull-up control node according to a driving input signal and a clock signal;
• a pull-up module, connected with a high level direct current signal input terminal, the pull-up control node, and a driving output signal output terminal, and configured to pull up a driving output signal according to the potential of the pull-up control node;
• a first pull-down control signal generation module, connected with a first signal input terminal, the driving input signal input terminal, the pull-up control node and a first pull-down control node, and configured to control potential of the first pull-down control node according to the driving input signal and the potential of the pull-up control node during a period that a first signal is at a high level;
• a second pull-down control signal generation module, connected with a second signal input terminal, the driving input signal input terminal, the pull-up control node, and a second pull-down control node, and configured to control potential of the second pull-down control node according to the driving input signal and the potential of the pull-up control node during a period that a second signal is at a high level, wherein the first signal and the second signal become a high level alternatively;
• and
• a pull-down module, connected with the first pull-down control node and the second pull-down control node, and configured to pull down the driving output signal according to the potential of the first pull-down control node and the potential of the second pull-down control node.
