PLASMA DISPLAY AND DRIVING METHOD FOR PLASMA DISPLAY PANEL

摘要

In a driving method for a plasma display panel provided with a plurality of discharge cells having a display electrode pair composed of a scanning electrode and a sustain electrode, a plurality of subfields having an initialization period, a writing period, and a sustain period are provided in one field period and at least two types of sustain pulses of a first sustain pulse which is the basis and a second sustain pulse whose rising edge is steeper than that of the first sustain pulse and whose trailing edge is easier than that of the first sustain pulse are applied to the scanning electrode in the sustain period. The second sustain pulse issequentially applied by a predetermined number of times immediately before an erase ramp waveform that allows the voltage to immediately drop when it rises from a base potential toward a predetermined potential (Vers) and reaches the predetermined potential (Vers) at the end of the sustain period.
