Energy recovery circuit and energy recovering method using the same

摘要

The present invention relates to an energy recovery circuit and energy recovering method using the same that is capable of reducing the number of components. An energy recovery circuit according to the present invention includes: a panel capacitor formed equivalently in a scan electrode and a sustain electrode; a scan electrode driver installed at a side of the scan electrode of the panel capacitor to supply a sustaining pulse to the side of the scan electrode; a sustain electrode driver installed at a side of the sustain electrode of the panel capacitor to supply the sustaining pulse to the side of the sustain electrode; one source capacitor commonly connected to the scan electrode driver and the sustain electrode driver to supply a voltage to the panel capacitor and to charge with a voltage discharged in the panel capacitor; and a path providing part to a current path of both the panel capacitor and the source capacitor when a voltage is supplied from the panel capacitor to the source capacitor.
