Abstract:
A driving circuit for driving a plasma display panel, the plasma display panel having a first electrode connected to a capacitor-like load of the plasma display panel, the first electrode being driven between a driving potential and a reference potential which is lower than the driving potential, the driving circuit comprising:a first voltage source(V1) for providing the driving potential; a second voltage source (V2) for providing a first potential, wherein the first potential is lower than one half of the driving potential; a first series circuit including a first inductor(L1) connected to both ends of the first voltage source (V1) and the first electrode, wherein electrical energy stored in the capacitor-like load is supplied by the first voltage source through the first inductor when the first series circuit is made conductive and the potential of the first electrode changes from the reference potential to the driving potential; a second series circuit including a second inductor(L2) connected to both ends of the second voltage source and the first electrode, wherein electrical energy transmitted to the second voltage source by the capacitor-like load through the second inductor when the second series circuit is made conductive and the potential of the first electrode changes from the driving potential to the reference potential; a first switch connected to both ends of the first voltage source and the first electrode, wherein the first switch turns on to conduct the first voltage source and the first electrode when the potential of the first electrode changes from the reference potential to the driving potential; a second switch connected to both ends of the second voltage source and the electrode, the second switch connecting the reference potential and the electrode when the second switch being turned on, and the potential of the electrode is changed from the driving potential to the reference potential.
