Abstract

Abstract Translated from French L'invention se rapporte à un dispositif de visualisation qui utilise une varistance (2) comme élément de commutation pour commander l'orientation des molécules composant une couche de cristal liquide (1). L'invention a pour objet d'agencer les connexions aux cellules élémentaires sur un substrat isolant (4) et de former sur des connexions des plots de varistance (2) assurant une commande à seuil desdites cellules. L'invention s'applique à la visualisation d'images transmises sous forme d'un signal vidéo, pour la télévision et les périphériques de visualisation, en télétransmission. The invention relates to a display device which uses a varistor (2) as a switching element to control the orientation of the molecules making up a layer of liquid crystal (1). The object of the invention is to arrange the connections to the elementary cells on an insulating substrate (4) and to form on connections varistor pads (2) ensuring a threshold control of said cells. The invention applies to the viewing of images transmitted in the form of a video signal, for television and viewing devices, by remote transmission.
