Plasma display device and driving apparatus thereof

摘要

A sustain or scan electrode driver for a plasma display device including a power recovery circuit, a voltage storage circuit, and a switching circuit. Power recovery is achieved by a coupling a power source at a minus sustain voltage to the sustain or scan electrode driver circuit that includes a capacitor and an inductor for creating resonance with the panel capacitor and recovering the power used in sustain discharge. Power loss of switches used in the driver circuit may be reduced and power recovery efficiency may be increased by using an additional capacitor in the driver circuit that maintains terminals of the switch at a predetermined level.
