  • Patent number: 7230381
    Abstract: A method of manufacturing a panel assembly is used for making a plasma display panel having electrodes and ribs formed on a substrate. The method includes the steps of forming the electrodes on the substrate so that these electrodes are extended to a periphery of the substrate to form their terminals, applying a terminal protective paste on the terminals for protecting the terminals, applying a rib paste on the entire area of a rib formation region provided on the substrate, molding the rib paste by use of a stamping die having cavities in the form of rib shape into green ribs, and firing the terminal protective paste and the green ribs simultaneously to form a terminal protective layer and ribs on the substrate.

  • Patent number: RE40104
    Abstract: On a first substrate provided on a display surface of a plasma display panel, bus electrodes (12a, 14a) in X and Y electrode lines (12, 14) forming a pair of display electrode lines are formed with an Ag material containing a black additive (RuO2, etc.) by a screen printing. This prevents external light from being reflected at the surfaces of the bus electrodes (12a, 14a) on the display side of an FP substrate (10) to improve the display contrast. The bus electrodes (12a, 14a) may be formed as a multi-layer structure. In this case, for example, the lower-layer bus electrodes are formed with a black metal material and the upper-layer bus electrodes are formed with a light-reflecting material layer, which improves light utilization efficiency and further improves the contrast.
