  • Method for manufacturing plasma display panel
    Patent number: 8152585
    Abstract: The present invention provides a method for manufacturing a plasma display panel having a front plate provided with a front substrate, a display electrode formed on the front substrate, a dielectric layer covering the display electrode, and a protective layer covering the dielectric layer. In the method above, after the protective layer has been formed, the front plate is processed in a moisture-free atmosphere for only a period where the front plate has a temperature of 400° C. or lower.
    Type: Grant
    Filed: November 10, 2009
    Date of Patent: April 10, 2012
    Assignee: Panasonic Corporation
    Inventors: Masaki Nishimura, Koyo Sakamoto, Ryousuke Sawa
  • Glass composition for lamp, glass part for lamp, and process for producing lamp or glass composition for lamp
    Patent number: 8067322
    Abstract: A glass composition for lamps includes the following by weight percent: SiO2: 60-75 wt %; CeO2+Ce2O3: 0.01-5.2 wt %; SnO+SnO2: 0.01-5.2 wt %; Al2O3: 0.5-6 wt %; B2O3: 0-5 wt %; Li2O+Na2O+K2O: 13-20 wt %; MgO: 0.5-5 wt %; CaO: 1-10 wt %; SrO: 0-10 wt %; BaO: 0-10 wt %; ZnO: 0-10 wt %; Fe2O3+FeO: 0-0.2 wt %; and TiO2: 0-1 wt %. The glass composition for lamps that contains no lead or antimony achieves high ultraviolet screening capacity, ensuring fewer occurrences of initial coloring and ultraviolet ray caused coloring of glass.
