摘要： A three electrode AC plasma display device including a plasma display panel and an improved energy recovery circuit. The energy recovery circuit uses resonance to efficiently drive a scan electrode and a sustain electrode with alternating sustain pulses to create a sustain discharge in a discharge cell. A panel capacitor lies between the sustain electrode and the scan electrode. According to one embodiment, a first inductor is coupled to the scan electrode and a second inductor is coupled to the sustain electrode. Four switches control connections within the energy recovery circuit. The first inductor creates a resonant circuit with the panel capacitor to transfer the sustain voltage from the scan electrode to the sustain electrode. The second inductor creates a resonant circuit with the panel capacitor to transfer the sustain voltage back from the sustain electrode to the scan electrode.
