Abstract
A power saving circuit for a liquid crystal panel (LCD) and a plasma display panel (PDP) recovers an energy charged in a panel capacitor through one path of a drive IC driving a scan electrode or data electrode for the PDP, and recovers the energy charged in the panel capacitor through one path of a column drive IC or row drive IC for the LCD panel. The energy recovery path can be a parasitic diode or protective diode of the drive IC. The power saving circuit can operate in an addressing period.
