  • Photosensitive thick-film paste materials for forming light-transmitting electromagnetic shields, light-transmitting electromagnetic shields formed using the same, and method of manufacture thereof
    Publication number: 20050037278
    Abstract: The present invention relates to light-transmitting electromagnetic shields which, when installed at the front of displays such as plasma display panels (PDP), cathode-ray tubes (CRT) or electroluminescent (EL) displays, have electromagnetic shielding properties that cut down on the emission of electromagnetic waves, have a high visible light transmittance, lower the reflectance to outside light, and have a good durability.

  • Insulator composition, green tape, and method for forming plasma display apparatus barrier-rib
    Patent number: 5985460
    Abstract: A coatable insulator composition for use in the formation of a green tape comprising fine inorganic micropowders composed of amorphous glass and a refractory oxide in a volatile organic solvent solution of a binder composed of a polymer substance and a plasticizer(s). A green tape obtained by coating said composition over a flexible substrate, and heating and drying this product to remove the organic solvent; and a method for forming a barrier-rib for a plasma display apparatus by sandblast etching using said green tape as an insulator layer for the barrier-rib formation. A use of a pre-formed green tape of uniform thickness in the formation of the barrier-rib of a plasma display apparatus allows the thickness uniformity of the barrier-rib to be improved and the work rationalized, which means that the plasma display apparatus can be made larger and finer, and mass production throughput will be enhanced.
