Abstract
An energy recovery circuit is provided that 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, and 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. The energy recovery circuit may further include a first diode coupled to the scan electrode side of the panel capacitor, a second diode coupled to the sustain electrode side of the panel capacitor, a first inductor commonly coupled to the sustain electrode side and the scan electrode side of the panel capacitor, a path providing part coupled to the first inductor, and a single source capacitor connected to the path providing part.
