Abstract

ENSEMBLE COMPRENANT UN ECRAN D’AFFICHAGE ET UN EMETTEUR DE LUMIERE OPTIQUE ET DISPOSITIF ELECTRONIQUE COMPRENANT UN TEL ENSEMBLE La présente description concerne un ensemble (10) pour un dispositif électronique comprenant :- un écran d’affichage (300) ;- un émetteur de lumière optique (100) adapté à émettre un faisceau de lumière infrarouge ou proche infrarouge (501) à travers l’écran d’affichage ;ledit émetteur de lumière optique et ledit écran d’affichage étant du type dans lequel, quand un faisceau de lumière non polarisée en provenance de l’émetteur de lumière optique passe à travers une région (301) de l’écran d’affichage, une tache blanche (601) d’une première intensité se forme dans ladite région ;- un polariseur de lumière (200) positionné entre l’émetteur de lumière optique (100) et l’écran d’affichage (300), ledit polariseur de lumière étant orienté de manière à ce qu’une tache blanche (602) d’une seconde intensité, inférieure à la première intensité, se forme quand le faisceau lumineux (502), en provenance de l’émetteur de lumière optique et polarisé par le polariseur de lumière, passe à travers la région de l’écran d’affichage.
