Abstract
Protective layer of front plate of the plasma display panel is formed of base protective layer and particle layer. Base protective layer is a thin film containing metal oxide. Particle layer is formed in a manner that aggregated particles of a plurality of magnesium-oxide single-crystal particles are stuck on base protective layer. The panel driving circuit drives the panel in a manner that an initializing discharge for forming wall charge is generated in a first subfield of the plurality of subfields, and an address discharge for erasing wall charge is generated in an address period of the plurality of subfields.
Claims2
A plasma display device comprising:
- a plasma display panel including:
- a front plate having display electrode pairs on a first glass substrate, a dielectric layer disposed so as to cover the display electrode pairs, and a protective layer disposed on the dielectric layer;
- a back plate having data electrodes on a second glass substrate, the back plate being disposed opposite to the front plate;
- and
- discharge cells formed at intersecting positions of the display electrode pairs and the data electrodes;
- and
- a panel driving circuit for driving the plasma display panel in a manner that a plurality of subfields are temporally disposed to form one field period, each of the subfields having an address period for generating an address discharge and a sustain period for generating a sustain discharge in the discharge cells,
- wherein the protective layer has
- a base protective layer formed of a thin film of containing metal oxide;
- and
- a particle layer formed in a manner that aggregated particles of plurality of single-crystal particles of magnesium oxide are stuck on the base protective layer, and
- wherein the panel driving circuit drives the plasma display panel in a manner that an initializing discharge for forming wall charge is generated in a first subfield of the plurality of subfields, and an address discharge for erasing wall charge is generated in an address period of the plurality of subfields.
