Abstract
A plasma display device in which a sustain pulse having a leading period is applied between row electrodes forming each row electrode pair by a number of times previously determined for each subfield, in a sustain period, and a length of the leading period of the sustain pulse is set in accordance with an accumulated light emission time or an accumulated use time of the plasma display panel.

1-12. (canceled)
A plasma display device for displaying an image on a plasma display panel in accordance with an input video signal, said plasma display panel having a plurality of row electrode pairs, and a plurality of column electrodes intersecting with said plurality of row electrode pairs, so as to form display cells at the intersections, respectively, and a display period for one field of the input video signal being configured of a plurality of subfields each formed of an address period and a sustain period for the image display, said plasma display device comprising:
- an addressing portion which selectively generates address discharge in each of said display cells in accordance with pixel data based on the video signal in the address period;
- and
- a sustaining portion which applies a sustain pulse having a leading period between row electrodes forming each of said row electrode pairs by a number of times previously determined for each of the plurality of subfields, in said sustain period;
- wherein said sustaining portion sets a length of the leading period of the sustain pulse in accordance with a temperature of the plasma display panel.
25-27. (canceled)
A method for driving a plasma display panel to display an image based on an input video signal, a display period for one field of the input video signal being configured of a plurality of subfields each formed of an address period and a sustain period,
- wherein a length of a leading period of a sustain pulse applied in the sustain period is set in accordance with a temperature of the plasma display panel.
