Abstract

A gate driving unit includes a first pull-down node control circuit, a second pull-down node control circuit and a pull-up node resetting circuit. The first/second pull-down node control circuit is configured to control a first/second pull-down node to be electrically connected to, or electrically disconnected from, a second/first control voltage end under the control of a potential at a pull-up node. The pull-up node resetting circuit is configured to control the pull-up node to be electrically connected to the second control voltage end under the control of a potential at the first pull-down node, and control the pull-up node to be electrically connected to the first control voltage end under the control of a potential at the second pull-down node.
