Abstract
The present invention relates to a plasma display apparatus and a driving apparatus of a plasma display panel. The plasma display apparatus and the driving apparatus of the plasma display panel according to the present invention comprises an energy storage unit connected to a voltage source that supplies a reference voltage, for supplying or recovering energy. The present invention can prohibit circuit loss and can enhance an energy recovery ratio by improving an energy recovery circuit of a sustain driver.
Claims15
A driving apparatus of a plasma display panel comprising an electrode, comprising:
- an energy storage unit connected to a voltage source that supplies a reference voltage, for supplying or recovering energy corresponding to a negative first voltage;
- a path forming unit for supplying the energy corresponding to the negative first voltage from the energy storage unit to an electrode through resonance, or for recovering the energy corresponding to the negative first voltage from the electrode to the energy storage unit through resonance;
- and
- a voltage application unit for applying a negative second voltage to the electrode after the energy corresponding to the negative first voltage is supplied and for applying the reference voltage to the electrode after the energy corresponding to the negative first voltage is recovered.
