  • Shift register and driving method thereof, gate driving circuit and display device
    Patent number: 11348501
    Abstract: The present disclosure provides a shift register and a driving method thereof, a gate driving circuit and a display device. The shift register includes: a pre-charging circuit coupled to a pre-charging signal input terminal and a pull-up node to pre-charge a potential of the pull-up node; a pull-down control circuit coupled to the pull-up node, a pull-down node and a reset signal input terminal to pull down a potential of the pull-down node or pull up the potential of the pull-down node; a pull-up circuit coupled to the pull-up node and a signal output terminal to pull up a potential of the signal output terminal; a pull-down circuit coupled to the pull-down node and the signal output terminal to pull down the potential of the signal output terminal; reset circuit coupled to the pull-up node and the pull-down node reset the potential of the pull-up node.
