  • Patent number: 7462989
    Abstract: A plasma display panel (PDP) includes front plate, scan electrodes and sustain electrodes both formed on front plate, dielectric layer covering scan and sustain electrodes, and protective layer formed on dielectric layer. Protective layer contains silicon (Si) and nitrogen (N), and is made of magnesium oxide (MgO) including Si of which atoms count in the range from 5×1018 pieces/cm3 to 8×1021 pieces/cm3. The foregoing construction allows the PDP to shorten a discharge-delay time, achieve a quick response of discharge to a voltage applied, and suppress changes of the discharge-delay time with respect to a temperature.

  • Publication number: 20080157672
    Abstract: Disclosed is a PDP and a manufacturing method therefor having improved display performance even if the PDP is of a fine-cell structure. A protective layer of the PDP is composed of an MgO film layer and an MgO particle layer that is made of MgO particles. The MgO particles are formed by burning an MgO precursor and satisfy that a/b?1, where a denotes a spectrum integral value in a wavelength region of a CL spectrum from 200 nm to 300 nm, exclusive of 300 nm, and b denotes a spectrum integral value in a wavelength region of the CL spectrum from 300 nm to 550 nm, exclusive of 550 nm. With provision of the MgO particle layer, the discharge characteristics of the protective layer improve (shorter discharge delay and less temperature dependence of the discharge delay). Consequently, the PDP is ensured to exhibit excellent display performance.

  • Publication number: 20070298162
    Abstract: An apparatus for manufacturing a protective layer includes a film-forming chamber (32); gas inlets (47) for introducing at least gas into the film-forming chamber (32); exhaust pumps (43) for evacuating the film-forming chamber (32); a cryotrap for controlling the exhaust velocity of water independent of the exhaust pumps (43); and a temperature controller for controlling the cooling temperature of the cryotrap. The exhaust velocity of the water is controlled by the cooling temperature of the cryotrap so as to form a protective layer susceptible to the partial pressure of water always under the same conditions. This results in a protective layer having resistance to sputtering and excellent secondary emission characteristics.
