Abstract

A gate driving unit includes: a pull-up node denoising circuit; a pull-down node control circuit; a pull-up node control circuit; and an energy storage circuit. The pull-up node denoising circuit is configured to, under control of a potential of the pull-down node, control coupling or discoupling between the first pull-up node and the input terminal. The pull-down node control circuit is configured to, under control of a control voltage, control the potential of the pull-down node; under control of a potential of the second pull-up node, control coupling or discoupling between the pull-down node and the input terminal. The pull-up node control circuit is configured to, under control of an anti-leakage control voltage, control coupling or discoupling between the first pull-up node and the second pull-up node, and configured to maintain the potential of the second pull-up node. The energy storage circuit is configured to store electric energy.
