  • Patent number: 8531356
    Abstract: In a plasma display panel, a protective layer of a front plate is formed of a base protective layer and a particle layer. The base protective layer is a thin film of metal oxide containing at least one of magnesium oxide, strontium oxide, calcium oxide, and barium oxide. The particle layer is formed in a manner that single-crystal particles of magnesium oxide having a peak of emission intensity at 200-300 nm two times or higher than another peak of emission intensity at 300-550 nm in the emission spectrum in cathode luminescence emission are stuck on the base protective layer. A panel driving circuit drives the plasma display panel with a subfield structure in which subfields are temporally disposed so that a magnitude of luminance weight has a monotonous decrease from a subfield where an all-cell initializing operation is performed to a subfield where a next all-cell initializing operation is performed.

  • Publication number: 20130017751
    Abstract: It is a method for manufacturing a plasma display panel having a discharge space, and a protective layer opposed to the discharge space. A gas containing a reducing organic gas is introduced into the discharge space, and the protective layer is exposed to the reducing organic gas. Then, the reducing organic gas is emitted from the discharge space. Then, a discharge gas is enclosed in the discharge space. The protective layer contains at least a first metal oxide and a second metal oxide. Furthermore, the protective layer has at least one peak in an X-ray diffraction analysis. The peak exists between a first peak of the first metal oxide in the X-ray diffraction analysis, and a second peak of the second metal oxide in the X-ray analysis. The first peak and the second peak show the same surface orientation as a surface orientation shown by the peak.
