Patent ID: 7777695

Claim:
A plasma display device having a plasma display panel, for displaying an image on said plasma display panel in accordance with an input video signal, said plasma display panel having a plurality of row electrode pairs, and a plurality of column electrodes intersecting with said plurality of row electrode pairs, so as to form display cells at the intersections, respectively, and a display period for one field of the input video signal being configured of a plurality of subfields each formed of an address period and a sustain period for the image display, wherein said plasma display panel includes: a front transparent substrate on which a dielectric layer is formed to cover said plurality of row electrode pairs; a rear substrate, disposed in parallel with said front transparent substrate, on which a protective layer is formed to cover said plurality of column electrodes; a fluorescent material layer formed on said protective layer to face a discharge space for each of said display cells; and a magnesium oxide layer formed on said dielectric layer to face the discharge space, containing magnesium oxide monocrystals which are excited by irradiating an electron beam in each of said display cells to emit cathode luminescence light having a peak within a wavelength range of 200 to 300 nm, said plasma display device comprising: an addressing portion which selectively generates address discharge in each of said display cells in accordance with pixel data based on the video signal in the address period; a sustaining portion which applies a sustain pulse between row electrodes forming each of said row electrode pairs in said sustain period; and a discharge timing controller which applies, in the sustain period, a discharge timing control pulse of a same polarity as that of the sustain pulse, to one row electrodes of the row electrode pairs, so that the discharge timing control pulse partly overlaps with a first sustain pulse in terms of time, which is applied to the other row electrodes of the row electrode pairs by said sustaining portion.
