  • Patent number: 7531961
    Abstract: Phosphor layers (110G, 110B, and 110R) are made of a combination of: blue and green phosphors that are positively charged on their surfaces and baked in an oxygen-nitrogen atmosphere to reduce oxygen vacancy, and that have a ?-alumina crystal structure; and a red phosphor made of an yttrium oxide compound. Uniformly forming such phosphor layers on the wall surfaces of barrier ribs (109) provides equal charge characteristics of the phosphors of respective colors, reduces oxygen vacancy in the phosphors, and inhibits adsorption of various gases in the panel production process. This can stabilize the discharge characteristics and prevent luminance degradation at driving the panel.

  • Patent number: 7476334
    Abstract: Disclosed here is a plasma display unit that employs phosphors having an amount of charge controlled close to zero, by which degradation in luminance, color temperature, and charge characteristics can be minimized. A phosphor bearing positive or negative charge is coated with a compound for controlling the amount of charge of the phosphor through a strong chemical bonding, whereby the amount of charge of a phosphor can be suppressed within ±0.01 ?C/g. Controlling the amount of charge of phosphors close to zero can keep impurity gases away from the phosphor particle when the panel is in operation, suppressing problems critical to driving a plasma display unit, such as luminance degradation of phosphors, improper alignment of color in panel operation, luminance degradation when the panel displays all white.
