Abstract

A shift register, a driving method, a gate driving circuit and a display device are provided. The shift register includes a scan control module, an output module, a pull-down module, a turn-off restoring module and a touch control module. The turn-off restoring module is electronically connected to the scan control module at a first node and electronically connected to the touch control module and the output module at a second node. The turn-off restoring module controls the first node to be electrically insulated from the second node during a touch scan phase, and restores a potential of the second node to a potential at a time instant before the touch scan phase when the touch scan phase is finished. The touch control module controls the output module to output a touch scan signal to an output terminal of the shift register during the touch scan phase.
