Abstract
The disclosure provides a shift register, a driving method for the shift register, a gate driving circuit and a display device. The shift register comprises an input component, a reset component, a node control module, a chamfering control component and an output component. By setting the chamfering control component and cooperation among the above five components, an amplitude of a scanning signal output by a driving signal output terminal is changed so as to generate a scanning signal with a chamfered waveform. When the scanning signal with the chamfered waveform is sequentially input to each pixel unit in a corresponding row by a corresponding gate line, a jump voltageVp on a pixel electrode of the pixel unit can be reduced, thereby mitigating phenomena such as flashing and image sticking of the display panel and improving the display quality of the display panel.
