Claim:
1. A shift register unit, which is arranged inside an in-cell touch panel, the in-cell touch panel comprising a substrate on which a common electrode is arranged, the shift register unit comprising a pre-charge module, a pull-up module, a pull-down maintenance module, a reset module, and a first signal output control module; wherein the pull-down maintenance module is connected to a first control signal input end, a reset signal input end, a third signal input end, a fourth signal input end, a pull-up node and a gate signal output end, and configured to pull down potentials at the pull-up node and the gate signal output end; the pull-up node is a point where the pre-charge module is connected to the pull-up module; the reset module is connected to a second control signal input end, the gate signal output end and a fourth signal input end, and configured to, at a touch stage within one frame of time, reset a potential of an output signal from the gate signal output end to be a potential of a fourth signal input in the fourth signal input end; and the first signal output control module is connected to the first control signal input end, the second control signal input end, a first common electrode signal input end, a first signal input end and a first signal output end, and configured to, at a display stage within one frame of time, control the first signal output end to output a first common electrode signal input in the first common electrode signal input end, and at the touch stage within one frame of time, control the first signal output end to output a first signal that is input in the first signal input end, the first signal is a signal inputted at the touch stage to a common electrode connected to the shift register unit.
