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.
