Abstract
A novel PDP device capable of reducing the peak current of a sustain discharge without the need to modify circuits has been disclosed. The PDP device is an AC-type gas-discharge display device comprising an AC-type gas-discharge panelhaving a plurality of first electrodes X and a plurality of second electrodes Y arranged by turns substantially in parallel and a plurality of third electrodes A arranges so as to intersect the first and second electrodes, and in which a cell is formed at the intersection of a combination of the first and second electrode and the third electrode, wherein a cell to be lit is selected during an address period and a discharge is caused to occur for the display in the selected cell by applying sustain pulses of opposite polarities alternately between the first and second electrodes during a sustain discharge period, the plurality of the third electrodes are divided into a first group and a second group, and a fixed voltage 0 V is applied to the third electrode of the first group and the third electrode of the second group is brought into a high impedance state during the sustain discharge period.
