  • Publication number: 20190304358
    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 VGL1 provides 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 VGL1, the third low level signal VGL3 and a threshold voltage Vth1 of the transistor in the output control module satisfy a relation of VGL3>VGL1+|Vth1|, such that in a phase following the output terminal outputting the high level signal, the output terminal completely outputs the third low level signal.
