Abstract
In a plasma display of the present invention, a VscH voltage is applied to a scan electrode during an address period, and a −Vs voltage is initially applied to the scan electrode during a sustain period. Subsequently, during the sustain period, a sustain pulse alternately having a Vs voltage and the −Vs voltage is applied by performing an energy recovery operation. Then, a hard switching generated during an early stage of the sustain period may be reduced.

A method of driving a plasma display comprising a plurality of first electrodes and a plurality of second electrodes, the method comprising:
- during an address period, applying a first voltage to a first electrode selected from the plurality of first electrodes, and applying a second voltage that is higher than the first voltage to the first electrodes not selected from the plurality of first electrodes;
- and
- during a sustain period, applying a third voltage to the plurality of second electrodes while decreasing a voltage at the plurality of first electrodes from the second voltage to a fourth voltage, and applying a sustain pulse alternately having the fourth voltage and a fifth voltage that is higher than the fourth voltage to the plurality of first electrodes.
A plasma display, comprising:
- a plasma display panel (PDP) comprising a plurality of first electrodes and a plurality of second electrodes;
- and
- a driver configured to, during a sustain period, apply a sustain pulse having a second voltage that is higher than a first voltage and a third voltage that is lower than the first voltage to the plurality of first electrodes while the first voltage is applied to the plurality of second electrodes,
- wherein the driver is further configured to apply a fourth voltage to a first electrode not selected from the plurality of first electrodes during an address period, and to apply the sustain pulse to the plurality of first electrodes after decreasing a voltage at the plurality of first electrodes from a fourth voltage to a third voltage during a sustain period.
