Patent ID: 7969386

Claim:
A plasma display apparatus, comprising: a plasma display panel having a first electrode and a second electrode that are separated from each other by a distance greater than 100 μm and less than or equal to 150 μm; a first electrode driver for supplying a first falling signal in a pre-reset period to the first electrode before supplying a rising signal in at least one subfield of several subfields of a frame; and a second electrode driver for supplying a second signal having a polarity opposite to a polarity of the first falling signal to the second electrode during the supply of the first falling signal, wherein a voltage magnitude of a lowest voltage of the first falling signal is greater than a voltage magnitude of a lowest voltage of a scan signal supplied during an address period, the first falling signal is gradually falling to the lowest voltage of the first falling signal, and the second signal sharply rises to a first voltage, wherein subsequent to application of the rising signal in the at least one subfield, the first electrode driver is adapted to supply a second falling signal and a third falling signal each having linear waveforms in a reset period, and the second falling signal has a polarity equal to a polarity of the rising signal, and the third falling signal has a polarity opposite to the polarity of the rising signal, wherein the first falling signal and the second signal are supplied in the at least one subfield of the several subfields of the frame, and the at least one subfield is first arranged among the several subfields in time order, wherein the second electrode driver comprises an energy recovery circuit unit for supplying a voltage of a sustain signal to the second electrode during a sustain period that follows the reset period before the address period, and the second electrode driver supplies a first sustain bias voltage to the second electrode by using a voltage charged to at least one capacitor of the energy recovery circuit unit in a part of a whole period when the third falling signal is supplied during the reset period, and a magnitude of the first sustain bias voltage is substantially equal to half of a voltage magnitude of the sustain signal.
