Gate driving unit, gate driving method, gate driving circuit, display panel and display device

A gate driving unit, comprising a start terminal, a first gate driving signal output terminal, a second gate driving signal output terminal,

• a pull-up control node control circuit, configured to control and maintain a potential of a pull-up control node to be a valid voltage under the control of a start signal inputted by a start terminal, and control the potential of the pull-up control node to be an invalid voltage under the control of a potential of a pull-down node;
• a pull-up node control circuit, configured to control a potential of a fist pull-up node and a potential of a second pull-up node based on the potential of the pull-up control node;
• a first gate driving signal output circuit, configured to control the connection of a first gate driving signal output terminal and a first clock signal terminal under the control of the potential of the first pull-up node, and control to reset a first gate driving signal outputted from the first gate driving signal output terminal under the control of the potential of the pull-down node;
• a second gate driving signal output circuit, configured to control the connection of a second gate driving signal output terminal and a second clock signal terminal under the control of the potential of the second pull-up node, and control to reset the second gate driving signal outputted from the second gate driving signal output terminal under the control of the potential of the pull-down node;
• and
• a pull-down node control circuit, configured to control and maintain the potential of the pull-down node under the control of a third clock signal inputted by a third clock signal terminal and a fourth clock signal inputted by a fourth clock signal terminal, and control to reset the potential of the pull-down node under the control of the potential of the pull-up control node.
