摘要： A plasma display device includes a plasma display panel and a driver unit driving the plasma display panel. The plasma display panel includes a first plate on which a sustain electrode and a scan electrode, a dielectric layer, an address electrode extending in a direction intersecting with the sustain electrode, and a protective layer are sequentially stacked and a second plate disposed to face the first plate via a discharge space. On the second plate, a barrier rib extending in the direction intersecting with the sustain electrode is formed. One edge part of the address electrode lies on the barrier rib and the other edge part of the address electrode lies on the discharge space. During an address period, the driver unit applies a scan pulse operating as an anode to the scan electrode and applies an address pulse operating as a cathode to the address electrode. This makes it possible to prevent erroneous discharge.

摘要： A plasma display device has a plasma display panel (PDP) and a driver unit driving the PDP. One field for displaying one screen of the PDP is made up of a plurality of subfields having a reset period and an address period. At least one of the plurality of subfields is a subfield for low luminance with number of times of sustain discharge being set to 0 (zero) and a voltage between a scan electrode and a sustain electrode during the address period being set smaller than a firing voltage between the scan electrode and the sustain electrode. The driver unit applies between the scan electrodes and the sustain electrodes a voltage smaller than the firing voltage between the scan electrodes and the sustain electrodes in a reset period of a subfield subsequent to the subfield for low luminance. As a result, luminance when reproducing black can be lowered.
