AC-type plasma display panel having energy recovery unit in sustain driver |
摘要 |
An apparatus of a sustain driver in an AC-type plasma display panel having an energy recovery unit, comprising: a first drive unit for driving one electrode of a panel capacitor to a sustain voltage or a ground voltage; a second drive unit for driving another electrode of the panel capacitor to a sustain voltage or a ground voltage; and a common energy recovery unit. The common energy recovery unit includes: an inductor connected to the one electrode of the panel capacitor and form a L-C resonance circuit with the panel capacitor; a first and second external capacitors connected in series between the power source of the sustain voltage and the ground; and a switch unit for selectively switching the L-C resonance circuit and the first and second external capacitors during the charge and discharge operation of the panel capacitor.
