Abstract: Set-up, write, sustain and erase pulses are variously applied to a plasma display panel using a staircase waveform in which the rising or falling portion is in at least two steps. These staircase waveforms can be realized by adding at least two pulses. Use of such waveforms for the set-up, write and erase pulses improves contrast, and use for the sustain pulses reduces screen flicker and improves luminous efficiency. This is of particular use in driving high definition plasma display panels to achieve high image quality and high luminance.

Abstract: A phosphor in which water adsorption onto the surface of a blue phosphor is inhibited, luminance degradation and chromaticity shift of the phosphor is decreased, or discharge characteristics thereof is improved, and a plasma display device using the phosphor. In phosphor layers used for plasma display, selectively coating at least the vicinity of the sides of planes of mirror symmetry containing Ba atoms in a blue phosphor with an oxide or a fluorine-containing oxide inhibits water adsorption onto the surface of the blue phosphor, decreases luminance degradation and chromacity shift of a phosphor, or improves discharge characteristics thereof.

Abstract: A plasma display device is provided in which deterioration in brightness of phosphor layers can be avoided. The plasma display device includes a plasma display panel in which a plurality of discharge cells in one color or in a plurality of colors are arranged and phosphor layers are arranged so as to correspond to the discharge cells in colors and in which light is emitted by exciting the phosphor layers with ultraviolet rays. The phosphor layers include blue phosphor, the blue phosphor being composed of an alkaline-earth metal aluminate phosphor containing at least one element selected from the group consisting of Mo and W. The addition of hexavalent ions (Mo, W) in the blue phosphor allows the elimination of oxygen defects in the vicinity of a layer containing Ba atoms (Ba—O layer), the suppression of adsorption of water to the surface of the blue phosphor and the improvement of deterioration in brightness and a change in chromaticity for the respective phosphors and discharge characteristics.

Abstract: Phosphor and a plasma display device are provided whose deterioration in brightness of phosphors and a degree of change in chromaticity are alleviated and whose discharge characteristics are improved and that has excellent initial characteristics. Phosphor of the present invention is an alkaline-earth metal aluminate phosphor containing an element M (where M denotes at least one type of element selected from the group consisting of Nb, Ta, W and B). In this phosphor, a concentration of M in the vicinity of a surface of the phosphor particles is higher than the average concentration of M in the phosphor particles as a whole. A plasma display device according to the present invention includes a plasma display panel in which a plurality of discharge cells in one color or in a plurality of colors are arranged and phosphor layers are arranged so as to correspond to the discharge cells in colors and in which light is emitted by exciting the phosphor layers with ultraviolet rays.

Abstract: A method of manufacturing a plasma display device which prevents the brightness of a phosphor layer from lowering is disclosed, and the method can form the phosphor layer in a stable manner because a nozzle is free from clogging. At least one of the phosphor layers has a green phosphor layer containing green phosphor having zero or positive charges and a crystal structure of Zn2SiO4:Mn. Green phosphor ink, whose major ingredient is the green phosphor, is applied through the nozzle to discharging cells, thereby forming the green phosphor layer. The green phosphor ink is formed of green phosphor powder coated with an oxide having positive charges, or the ink is formed by crushing the green phosphor powder originally having negative charges and a crystal structure of Zn2SiO4:Mn such that the powder changes to have positive charges.
