摘要:
Phosphor layers (110G, 110B, and 110R) are made of 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 have a β-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.

摘要:
The first object of the present invention is to provide a PDP with improved panel brightness which is achieved by improving the efficiency in conversion from discharge energy to visible rays. The second object of the present invention is to provide a PDP with improved panel life which is achieved by improving the protecting layer protecting the dielectrics glass layer. To achieve the first object, the present invention sets the amount of xenon in the discharge gas to the range of 10% by volume to less than 100% by volume, and sets the charging pressure for the discharge gas to the range of 500 to 760 Torr which is higher than conventional charging pressures. With such construction, the panel brightness increases. Also, to achieve the second object, the present invention has, on the surface of the dielectric glass layer, a protecting layer consisting of an alkaline earth oxide with (100)-face or (110)-face orientation. The protecting layer, which may be formed by using thermal Chemical Vapor Deposition (CVD) method, plasma enhanced CVD method, or a vapor deposition method with irradiation of ion or electron beam, will have a high sputtering resistance and effectively protect the dielectrics glass layer. Such a protecting layer contributes to the improvement of the panel life.

摘要:
The present invention aims to provide a method of producing a plasma display panel in which the fluorescent substance layer or the reflection layer is formed easily and accurately even for a minute cell structure, and in which the fluorescent substance layer or the reflection layer is formed evenly in the channels between the partition walls formed in stripes, or such a layer is formed also on the sides of the partition walls. To achieve this purpose, a fluorescent substance layer or a reflection layer is formed by applying a fluorescent substance ink or a reflection material ink continuously onto the channels, the ink being spouted out from a nozzle which runs along the partition walls. The nozzle may be directed to one side of the plurality of partition walls while running. Pressure may be put upon the ink having been applied onto the channels so that the ink sticks to both sides of the partition walls. The ink may be continuously spouted out from a nozzle while a bridge is formed between the nozzle and both sides of the partition walls by surface tension of the ink. A plate with a plurality of partition walls and channels in between may be formed so that adsorption of the sides of the channels against the ink is higher than that of the bottom of the channels.
摘要:
The plasma display panel of the present invention has, for achieving high luminance and high reliability, a plurality of discharge spaces formed between a front panel and a back panel that are disposed to oppose each other, and phosphor layers, formed in the discharge spaces, each including phosphor particles of one of blue, red and green colors, wherein the phosphor particles of at least one of blue, red and green colors included in the phosphor layer are flake-like particles.
摘要:
The present invention intends to provide a manufacturing method for a PDP that can continuously apply phosphor ink for a long time and can accurately and evenly produce phosphor layers even when the cell construction is very fine. To do so, phosphor ink is continuously expelled from a nozzle while the nozzle moves relative to channels between partition walls formed on a plate so as to scan and apply phosphor ink to the channels. While doing so the path taken by the nozzle within each channel between a pair of partition walls is adjusted based on position information for the channel. When phosphor particles is successively applied to a plurality of channels, phosphor ink is continuously expelled from the nozzle even when the nozzle is positioned away from the channels. The phosphor ink is composed of: phosphor particles that have an average particle diameter of 0.5 to 5 &mgr;m; a mixed solvent in which materials selected from a group consisting of terpineol, butyl carbitol acetate, butyl carbitol, pentandiol, and limonene are mixed; and a binder that is an ethylene group polymer or ethyl cellulose containing at least 49% of ethoxy group (—OC2H5) cellulose molecules. After dispersion a charge-removing material is added to the phosphor ink.
