Description
Nematic liquid crystals can be electrically addressed when sandwiched in thin layers. In this paper a liquid crystal optical data composer which is X-Y addressed using the electro-optical effect of index modulation, a field effect, realised for an a.c. electric field on an Homeotropic structure is presented. It is a 128x128 dots display capable of presenting at the same time 1.6x104 digital optical data, with overall writing times of a few milliseconds
Abstract (French)
Les cristaux liquides nematiques peuvent etre adresses electriquement lorsqu'ils sont montes en couches minces. On presente dans cette communication un composeur de donnees optiques a cristaux liquides a adressage matriciel, mettant en oeuvre l'effet electro-optique de modulation d'indice, ou effet de champ, obtenu dans une structure homeotrope soumise a un champ electrique alternatif. Il s'agit d'un dispositif d'affichage de 128x128 points capable de presenter simultanement 1,6x104 informations optiques digitales, l'ensemble etant inscrit en quelques millisecondesAdditional details
