Abstract: A shift register, a gate driving circuit, a display screen and a method for driving the display screen are proposed. A first and/or a second node control unit are incorporated. The first node control unit controls a first node according to a first control signal to put a pulling-up unit in an OFF state; the second node control unit controls a second node according to a second control signal to put a pulling-down unit in an OFF state. During the period that the display screen is powered off, the level at the driving signal output terminal is prevented from being affected by the pulling-up unit through the first node control unit and by the pulling-down unit through the second node control unit, such that thin film transistors connected to a gate line corresponding to the shift register are all turned on and thus accumulated charges can be released rapidly.

The driving unit of the touch driving electrode includes a start signal shift sub-unit, configured to control a start signal output terminal to output a first level during an adjacent time period next to a time period in which a potential of the start signal is the first level, then reset the start control signal so as to control the start control signal output terminal output the second level, and control the touch driving signal output terminal to output a touch scanning signal when the potential of the start control signal and the potential of the touch control signal are both the first level. The first clock signal has a phase opposite to that of the second clock signal.
