The invention provides a shift register unit, a driving method therefor, a grid drive circuit, and a display device. The shift register unit comprises a pull-up module, a pull-down module, a first capacitor, a first noise amplification module, and a compensation module. The pull-up module is used for the pulling-up of a signal outputted by the shift register unit according to a starting signal inputted by a starting signal input end. The pull-down module is used for the pulling-down of a signal outputted by the shift register unit according to a reset signal inputted by a reset signal input end. The first capacitor is used for improving the potential of a pull-up node at a pull-up stage. The first noise amplification module is used for noise amplification of the signal outputted by the shift register unit at a pull-down stage. The compensation module is used for the potential compensation of the pull-up node at a touch stage according to a touch control switching signal inputted by a touch control switching end. The shift register unit can avoid mutual interference between embedded type touch display screen drive and display drive, and achieves that the embedded type touch display screen drive and display drive are compatible with each other.
