Abstract

Ce procédé consiste en substance dans l'application sur un substrat de plusieurs couches superposées de cristaux liquides, chaque couche ayant la forme d'une image de la séquence à representer et étant constituée par un mélange de cristaux liquides changeant de couleur à une température différente de celle à laquelle les autres couches superposées changent de couleur.
