Plasma display device and plasma display panel drive method

A plasma display device comprising:

• a plasma display panel having a plurality of discharge cells, each discharge cell having a display electrode pair formed of a scan electrode and a sustain electrode;
• and
• a sustain pulse generating circuit for generating a sustain discharge by applying a sustain pulse to the display electrode pairs,
• wherein the sustain pulse generating circuit sets a rising time period of a sustain pulse for generating a sustain discharge just before a final sustain discharge in the sustain period to be shorter than that of at least one of other sustain pulses and sets a repetition period of the sustain pulse for generating the sustain discharge just before the final sustain discharge in a sustain period to be longer than the repetition period of at least one of other sustain pulses.

A plasma-display-panel driving method in which one field includes a plurality of sub fields, each sub field having an address period in which an address discharge is selectively generated in discharge cells and a sustain period in which a sustain discharge is generated by applying a sustain pulse by the number of times corresponding to a brightness weight, the method comprising:

• raising or lowering the sustain pulse by allowing an inter-electrode capacitor of a display electrode pair including a scan electrode and a sustain electrode and an inductor to resonate;
• and
• clamping a voltage of the sustain pulse to a predetermined voltage,
• wherein a rising time period of a sustain pulse for generating a sustain discharge just before a final sustain discharge in the sustain period is set to be shorter than that of at least one of other sustain pulses and the sustain pulse for generating a sustain discharge just before the final sustain discharge in the sustain period is set to a sustain pulse other than a sustain pulse having the shortest repetition period.
