  • the invention aims to realise said screen in such a manner that one or several parts thereof are controlled separately, so that certain parts in the shape of suitable patterns, surfaces or such can be made transparent or non- transparent .
  • Such an arrangement can be realised for example by providing the above-mentioned film as a uniform, electrically conductive layer on one side, and by applying the electrically conductive layer according to a specific pattern on the other side.

Abstract

L'invention concerne un écran optiquement réglable comprenant au moins deux couches de verre ou d'un matériau (2, 3) synthétique transparent. Ces couches sont pourvues d'une couche d'un matériau (4, 5) transparent électroconducteur. Une couche de cristaux liquides (6) est placée entre les couches; ses caractéristiques optiques, en particulier la transparence, peuvent être réglées entre un état transparent et un état opaque de l'écran. Au moins une de ces couches (4, 5) électroconductrices est divisée en au moins deux zones (23-24-25-26-27-28-29) séparées l'un de l'autre. Chacune de ces zones est électriquement connectée à une source (36) d'alimentation, et un commutateur (30-31-32-33-34-35) est placé dans au moins une zone de connexion.
