  • Protective layer material for PDP and method of manufacturing the same
    Patent number: 7868550
    Abstract: An MgO protective layer formed on a front substrate of a plasma display panel and a method of manufacturing the protective layer are disclosed. The protective layer is manufactured by using an MgO pellet, which is simultaneously doped with a first doping material of BeO and/or CaO among alkali earth metals and a second material selected from the group consisting of Sc2O3, Sb2O3, Er2O3, Mo2O3, and Al2O3, as a deposition source through a vacuum deposition method. The protective layer remarkably improves a discharge efficiency of the PDP and shortens a discharge delay time, so that it is applied to a signal can PDP. Also, it lowers a manufacturing cost by reducing the number of electronic components.
