Patent ID: 7733305

Claim:
A plasma display device in which a plasma display panel provided with display cells having a discharge space formed at intersections of a plurality of row electrode pairs and a plurality of column electrodes arranged to cross said row electrode pairs is driven for respective N sub-fields to display images for one frame, said plasma display device comprising: a dielectric layer covering the plurality of row electrode pairs, a magnesium oxide layer comprising magnesium oxide crystals disposed on the dielectric layer and facing the discharge space, the magnesium oxide crystals including magnesium oxide single crystals that cause a cathode luminescence having a peak in a wavelength range of 200 to 300 nm when an electron beam is irradiated on to the magnesium oxide single crystals and that have a particle diameter of 2000 angstroms or more; an address portion that applies a scanning pulse sequentially to one electrode of each of said row electrode pairs and applies a data pulse corresponding to an input video signal to cause selective discharge in said discharge space of each of the display cells and to set each of said display cells to a turned-on cell state or a turned-off cell state in each of said sub-fields; a sustain portion that applies a sustain pulse to said row electrode pairs in each of said sub-fields to cause sustain discharge in said discharge space of each of said display cells set to said turned-on cell state; and a reset portion that applies a reset pulse to said row electrode pairs in M sub-fields of said N sub-fields (0<M<N) to cause reset discharge in said discharge space of each of said display cells and to initialize all said display cells.
