1. A shift register, comprising:
an output control module, a full screen reset module, a cascade output module and an output module that are electrically connected, wherein
the output control module is configured to turn on when there is no electrostatic discharge in the shift register to transmit a signal of a first node to a second node so that a first gate signal output terminal outputs a target signal configured to drive a current row of display element to display or not display, or the output control module is configured to turn off when there is electrostatic discharge in the shift register;
the full screen reset module is configured to reset the potential of the second node and the potential of the first gate signal output terminal when there is electrostatic discharge in the shift register, the first gate signal output terminal not outputting any signal when the output control module is turned off and the second node and the first gate signal output terminal are in a reset state;
the cascade output module is configured to provide a first voltage signal to a second gate signal output terminal under the control of a first driving signal when there is electrostatic discharge in the shift register, or the cascade output module is configured to provide a second voltage signal to a second gate signal output terminal under the control of a second driving signal, a signal output by the second gate signal output terminal being configured to drive a next row of display element to display or not display;
the output module is configured to provide a signal of a first clock signal terminal to the first gate signal output terminal under the control of a signal of the second node, or the output module is configured to provide a signal of a first reference voltage terminal to the first gate signal output terminal under the control of a signal of a third node, or the output module is configured not to output any signal when the output control module is turned off.
