Plasma display panel driving method and plasma display device

A plasma display apparatus comprising:

• a plasma display panel that has a plurality of discharge cells each of which has a display electrode pair formed of a scan electrode and a sustain electrode, and a data electrode;
• and
• a driver circuit that forms one field using a plurality of subfields each of which has an address period and a sustain period, and drives the plasma display panel,
• wherein
• the driver circuit includes a plurality of scan ICs for applying scan pulses to a predetermined number of scan electrodes disposed continuously,
• scan electrodes driven by one of the scan ICs are divided into two scan electrode groups:
• a scan electrode group formed of an odd-numbered scan electrodes;
• and a scan electrode group formed of an even-numbered scan electrodes,
• the scan IC sequentially applies scan pulses to one scan electrode group of the two groups, and then sequentially applies scan pulses to another scan electrode group of the two groups,
• a pulse width of scan pulses applied to a first through predetermined-numbered scan electrodes belonging to the one scan electrode group is set to be longer than a pulse width of scan pulses applied to remaining scan electrodes belonging to the one scan electrode group, and
• a pulse width of scan pulses applied to the first through predetermined-numbered scan electrodes belonging to the another scan electrode group is set to be longer than pulse width of scan pulses applied to remaining scan electrodes belonging to the another scan electrode group.
