  • Patent number: 7528548
    Abstract: A crystalline magnesium oxide layer, including magnesium oxide crystals causing a cathode-luminescence emission having a peak within a wavelength range of 200 nm to 300 nm upon excitation by an electron beam, is provided between the front glass substrate and the back glass substrate, facing the discharge cells. The phosphor layer of any one of red, green and blue colors has a discharge timing adjusting function for giving rise to an approximate match between a timing of a discharge initiated in the green discharge cell and a timing of a discharge initiated in the red or blue discharge cell.

  • Patent number: 6831412
    Abstract: A plasma display panel comprises a front glass substrate and a back glass substrate. A plurality of row electrode pairs regularly arranged in a column direction, each extending in a row direction to form a display line, and a dielectric layer covering the row electrode pairs are provided on an inner surface of the substrate. A plurality of column electrodes are provided on an inner surface of the substrate, and regularly arranged in the row direction, each extending in the column direction to intersect with the row electrode pairs to form discharge cells in a discharge space at the intersections. A recess groove is formed in a portion of the dielectric layer opposite a discharge gap between paired row electrodes constituting the row electrode pair, so that the dielectric layer has a thickness in the portion opposite the discharge gap smaller than that in portions on both sides of the portion opposite the discharge gap.
