Abstract:
1. A PDP apparatus comprising a panel unit and a driving unit, the panel unit including a first substrate on which a plurality of pairs of first and second electrodes are formed and a second substrate on which a plurality of third electrodes are formed, the first substrate and the second substrate being opposed to each other with a discharge space therebetween so as to form discharge cells at areas where the plurality of pairs of first and second electrodes intersect the plurality of third electrodes, the driving unit driving the panel unit to display an image according to a display method that includes a write period and a sustain period, by, in the sustain period, applying a voltage to the plurality of pairs of first and second electrodes and applying a voltage to the plurality of third electrodes, the PDP apparatus being characterized in that the plurality of third electrodes are divided into a plurality of groups of third electrodes, each of the plurality of groups of third electrodes include two or more third electrodes, and in the sustain period, the driving unit applies the voltage to the plurality of third electrodes such that waveforms of the voltage applied to the plurality of third electrodes differ among the plurality of groups of third electrodes in terms of a rise start timing which is set relative to a time at which the voltage applied to the plurality of pairs of first and second electrodes reaches a predetermined level.
