Abstract
A plasma display driving method capable of displaying a vigorous image having enhanced maximum luminance and contrast. For this purpose, one field is divided into a plurality of sub-fields each including a sustain period. In the sustain period, the number of sustain pulses obtained by multiplying a proportionality factor by a brightness weight set for each of the sub-fields are applied to display electrode pairs to generate sustaining discharge in discharge cells having generated addressing discharge therein. Thus, the total number of the sustain pulses in one field period can be changed. When a predetermined image meeting predetermined conditions is displayed, the total number of the sustain pulses in one field period is made larger than those in the case where the other normal images are displayed.
