Shift register unit, grid electrode driving circuit and display device

The utility model provides a shift register unit, a grid electrode driving circuit and a display device, and relates to the technical field of display. The shift register unit comprises an input reset module, a pull-up module, a control module and a pull-down module. The shift register unit, the grid electrode driving circuit and the display device have the advantages that high electric levels are inputted into a second signal input end of the input reset module during touch scanning, so that electric levels of a pull-up control node can be kept, electric leakage of the pull-up control node can be effectively prevented, insufficient charge rates of line pixels can be prevented, and dark lines or insufficient bright lines can be improved.
