摘要： A plasma display device including a scan circuit, a plasma display panel, and a plurality of power sources for driving the plasma display panel. The scan circuit is configured to apply scan voltages to scan electrodes of the plasma display panel in order to select light-emitting cells and non-light-emitting cells during an address period. The scan circuit includes a capacitor configured to remove the need to provide a current cut-off switch to prevent undesirable current flowing between the power supplies during the operation of the plasma display.

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.
