1. The shift register unit is characterized by comprising an input end, a reset end, a first output end and a second output end, and further comprising:

  • the input module is respectively connected with the input end and the first node and used for pulling up the potential at the first node to a high level when the input end receives a cascade trigger signal;

    the first output module is respectively connected with the first node and the first output end and used for outputting a gate driving signal at the first output end at the next level turnover moment of a clock signal after the electric potential at the first node is pulled up to a high level;

    the second output module is respectively connected with the first node and the second output end and used for outputting a cascade trigger signal at the second output end at the next level turnover moment of the clock signal after the potential at the first node is pulled up to a high level;

    the reset module is respectively connected with the reset terminal, the first node, the first output terminal and the second output terminal, and is used for pulling down the potential at the first node to a low level when the reset terminal receives a cascade trigger signal and stopping the signal output of the first output terminal and the second output terminal;

    the reset module comprises a pull-down submodule, a first overturning submodule, a second overturning submodule and a pull-down control submodule;

    wherein the content of the first and second substances,the pull-down submodule is respectively connected with a second node, the first output end and the second output end, and is used for pulling down the potential at the first node to a low level and stopping the signal output of the first output end and the second output end when the second node is at a high level;

    the first turning submodule is respectively connected with the reset terminal, the input terminal and the first node and is used for conducting the first node to the input terminal when the reset terminal receives a cascade trigger signal;

    the second turning submodule is respectively connected with the reset terminal and the second node, and is used for setting the second node to be at a high level when the reset terminal receives a cascade trigger signal;

    the pull-down control submodule is respectively connected with the first node and the second node and is used for pulling down the electric potential of the second node to a low level when the first node is at a high level and pulling up the electric potential of the second node to a high level when the first node is at a low level.
