Abstract
1381077 Liquid crystal cell ELECTROVAC FABRIKATION ELEKTROTECHNISCHER SPEZIALARTIKEL GmbH 21 June 1973 [3 July 1972] 29564/73 Heading H4F In a liquid crystal cell comprising two plates joined at their marginal areas by a rim of different material, an opening is left in the rim for filling the cell with liquid crystal material, after which it is hermetically sealed. As described, the plates are of glass and the rim of glass solder. A further opening in the rim may be provided for venting purposes. The openings are sealed with synthetic resin, or by encircling each opening with a stored, vapour deposited or cathodically vaporized metal coating followed by sealing by depositing solder per se or by soldering a metal pad to the coating. The coating may include a layer which adheres strongly to the glass, an easily solderable layer and an overlying oxidation resistant layer, e.g. or Cr-Sn-Au(optional). A stack of cells may be formed, the openings being offset from each other. The cells may be filled in vacuo or under pressure. The cell may include thin layer electrodes.
