Abstract
The present disclosure provides a shift register, a driving method of the shift register, an emission driving circuit, and a display device. The shift register includes a first node control module, a second node control module and an output control module. A first low level signal VGLprovides low level at a first node, and a high level signal provides high level at a second node. The output control module includes a transistor for outputting low level, so that an output terminal outputs a third low level signal. The first low level signal VGL, the third low level signal VGLand a threshold voltage Vthof the transistor in the output control module satisfy a relation of VGL>VGL+|Vth|, such that in a phase following the output terminal outputting the high level signal, the output terminal completely outputs the third low level signal.
