`
`Listing of Claims:
`
`1.
`
`(Currently Amended)
`
`A method of driving a plasma display panel
`
`provided with a plurality of discharge cells, each having a scan electrode and a sustain
`
`electrode, comprising:
`
`forming one—field period by arranging a plurality of sub-fields including an
`
`initializing period for generating initializing discharge at the discharge cell, an address
`
`period for generating address discharge at the discharge cell, and a sustain period for
`
`emitting light from the discharge cell by alternately applying a periodic pattern of at
`
`least one first sustain pulse for generating emission having one peak at the discharge
`
`cell and at least one second sustain pulse for generating emission having two peaks at
`
`the discharge cell, a plurality of times to the scan electrode and the sustain electrode,
`
`wherein the periodic pattern includes the at least one first sustain pulse being
`
`alternately applied to the scan electrode and the sustain electrode a first
`
`integer
`
`number of times, consecutively followed by the at least one second sustain pulse being
`
`applied to the scan electrode and the sustain electrode a second integer number of
`
`times which is different—less than the first integer number of times, and
`
`a rise time of the at
`
`least one second sustain pulse applied to the scan
`
`electrode and a rise time of the at
`
`least one second sustain pulse applied to the
`
`sustain electrode are individually set in accordance with a ratio of discharge cells for
`
`emitting light in the sustain period of sub-fields, and
`
`a rise time of the at least one first sustain pulse is set independent of the ratio
`
`of discharge cells for emitting light in a respective subfield of the plurality of subfields.

`
`second sustain pulse applied to the scan electrode is set longer than the rise time of
`
`second sustain pulse applied to the sustain electrode.
