Abstract
A shift register, a method for driving the same, a gate drive circuitry and a display apparatus are provided. The shift register includes: an input circuit, connected to a signal input terminal, a pull-up node and a first control terminal, and configured to provide a signal of the signal input terminal to the pull-up node under the control of the first control terminal; an output circuit, connected to the pull-up node, a first clock signal terminal and a signal output terminal, and configured to provide a signal of the first clock signal terminal to the signal output terminal under the control of the pull-up node; and a pull-up node control circuit, connected to the pull-up node, a second clock signal terminal, a third clock signal terminal and a first voltage terminal, and configured to provide a signal of the first voltage terminal to the pull-up node.
