Abstract:
1. A method for driving a plasma display panel in which a first substrate and a second substrate are positioned facing each other sandwiching a discharge space in which discharge gas is sealed, and a pixel cell including a fluorescent layer is formed at each intersection of a plurality of row electrode pairs formed on said first substrate and a plurality of column electrodes formed on said second substrate, by dividing one field display period of a video signal into a plurality of subfields and driving each subfield independently, wherein said one field display period has: a plurality of subfields, each of which executes an address process for setting said pixel cells to ON mode or OFF mode by address-discharging said pixel cells selectively according to a pixel data of each pixel based on a video signal, and a sustain process for repeatedly sustain-discharging only said pixel cells being set to said ON mode for a number of times assigned corresponding to a brightness weight of said subfield by sequentially applying a sustain pulse to one row electrode of said row electrode pair and to the other row electrode alternately for said number of times; and a subfield for executing a reset process for initializing each of said pixel cells to one state out of said OFF mode and said ON mode by reset-discharging each of said pixel cells, in addition to said address process and said sustain process, and in said one field display period, an auxiliary pulse is applied to said column electrode only while a first sustain pulse is being applied in said sustain process of at least one subfield out of the subfields in which said reset process is not executed.
