Abstract:
1. An energy recovery circuit for a plasma display panel (PDP), comprising: an energy recovery unit recovering and storing energy from the PDP; and a switching stabilizing unit electrically connected to the energy recovery unit to stabilize switching of a sustain discharge pulse applied to the PDP, wherein, when energy is recovered from the PDP, the switching stabilization unit allows a first capacitor for energy recovery of the energy recovery unit and a second capacitor for energy recovery of the switching stabilization unit to be connected in parallel, so that the energy is recovered to the first and second capacitors for energy recovery through different paths; and when the recovered energy is supplied to the PDP, the switching stabilization unit allows the first and second capacitors for energy recovery to be connected in series, so that the energy is supplied to the PDP through one path.
