  • Patent number: 7504126
    Abstract: A plasma display panel is composed of a first substrate and a second substrate facing each other via a discharge space and sealed together. A protective layer on the first substrate is composed principally of magnesium oxide, includes a substance or structure that creates a first energy level in an area of a forbidden band, the area being in a vicinity of a conduction band, and includes a substance or structure that creates a second energy level in another area in the forbidden band, the other area being in a vicinity of a valence band. During driving the second energy level is occupied by electrons, and few electrons exist in the first energy level, or electrons can easily occupy the first energy level due to a minus charge state, and MgO insultaive resistance is not lowered. This maintains wall charge retention and reduces discharge irregularities and firing voltage Vf.

  • Patent number: 7449213
    Abstract: A phosphor paste is applied to inner surfaces of a cell. Then, a conveyer moves a substrate relative to a CCD camera at a constant speed. Simultaneously, two LEDs radiate visible light onto a portion, to be inspected, of the substrate. The visible light is light configured to have a wavelength so as to be able to prevent the phosphor of the phosphor paste from being excited and emitting light and reflected by a liquid surface of the phosphor paste to produce reflected light. Thereafter, the CCD camera captures an image of the phosphor paste and a data processor processes the received image data, and determines whether a phosphor layer formed by drying the phosphor paste will normally be formed, prior to formation of phosphor layer.
