ABSTRACT:
Driving a plasma display panel, in which generation of a region having brightness non-uniformity can be reduced over an entire screen without changing the voltage and pulse width of sustain pulses, to enable suppression of an increase in power consumption. This driving of the plasma display panel comprises (i) an initialization period for forming a discharge cell at an intersection where a scan electrode and a sustain electrode meet a data electrode and generating initialization discharge in the cell, (ii) a writing period for generating writing discharge in the discharge cell, and (iii) a sustain period for generating sustain discharge by alternately applying sustain pulses to the scan electrode and sustain electrode of the discharge cell. The rise time of the sustain pulses applied to the scan electrode and sustain electrode during the sustain period is shortened at a frequency of once every several times.
