  • Patent number: 7723919
    Abstract: The present invention provides a front panel for a plasma display panel which can suppress the incidence of chipping of the barrier rib of a rear panel for a PDP, can enhance the stability of initial electron emission in a dielectric layer, and can reduce a voltage required for maintaining a wall charge. The front panel for a plasma display panel includes a substrate, a plurality of electrodes formed on the substrate, a dielectric layer formed to cover the respective electrodes and the substrate, a dielectric-protection layer formed to cover the dielectric layer, and powder components dispersed on the dielectric-protection layer, wherein an annealed layer having a thickness of 10 to 300 nm is formed on at least the exposed surface of each of the powder components, wherein said exposed surface does not contact the dielectric-protection layer.

  • Patent number: 7690961
    Abstract: A fluorine-containing precoating is formed to cover a phosphor particle by, for example, a physical vapor deposition of a fluoride. Then, a fluorine-containing coating covering the phosphor particle is formed by supplying fluorine into the precoating. This obtained phosphor particle with the coating is applied in the form of a paste to a substrate on each electrode between two adjacent ribs to form a phosphor layer including phosphor particles between the ribs on the substrate. The substrate is positioned with respect to another substrate having electrodes thereon to form discharge spaces between the substrates. The discharge spaces are filled with a discharge gas to produce a plasma display panel.
