Abstract
A method of switching a high-side switch of a plasma display panel (PDP) scan circuit in zero-voltage-switching mode. The scan circuit contains a high-side switch and a low-side switch. By controlling the voltage potential difference across the high-side switch, the high-side switch of the PDP scan circuit can operate using soft switching or in zero-voltage-switching (ZVS) mode. The switching loss of scan ICs and the switching noise from scan ICs will therefore be reduced.
