Patent

CA 2278293

The present invention consists of materials and a processing method for coating rigid-rod poly(ionomers) or salts thereof, in a solvent system, directionally on charged surfaces resulting in the formation of liquid crystal display surfaces with planar alignment and pretilt.

L'invention porte sur des matériaux et des procédés de traitement permettant le dépôt de revêtements de poly(ionomères) à bâtonnets rigides ou leurs sels, placés dans un système de solvants et dirigés sur des surfaces chargées, ce qui produit la formation de surfaces d'affichages à cristaux liquides à alignement plane et préorientation.
