Claim 15:
16. An operation method of a scan driving circuit, the scan driving circuit comprising a pull-up output charging circuit, a pull-down discharge circuit, an anti-noise start-up circuit and an anti-noise pull-down discharge circuit, the anti-noise pull-down discharge circuit electrically connected to the pull-up output charging circuit and the pull-down discharge circuit through a driving node, the pull-up output charging circuit and the pull-down discharge circuit electrically connected to an output terminal, and the operation method comprising:
in a non-working state, enabling the anti-noise pull-down discharge circuit through the anti-noise start-up circuit to pull down an electric potential of the driving node; and
when the electric potential of the driving node is pulled down, disabling the pull-down discharge circuit and enabling the pull-up output charging circuit, thereby pulling up an electric potential of the output terminal.
