Abstract

TITRE : Film d’écran tactile et écran ainsi qu’appareil ainsi équipé Film (100) pour un écran image tactile (105) et ayant une plage de couplage (125), une plage de découplage (135), une plage de pression (140) avec un hologramme de pression (145). La plage de couplage (125) couple le rayonnement optique (130) d’une source (115). La plage de découplage (135) découple le rayonnement optique (130). La zone d’appui (140) comprend l’hologramme de pression (145) dans le chemin de rayonnement (150) entre la plage de couplage (125) et la plage de découplage (135). En fonction de la pression appliquée sur la zone d’appui (140) l’hologramme de pression (145) diffracte une fraction du rayonnement (130) le long du chemin de rayonnement (150) et/ou découple une fraction du rayonnement (130) hors du chemin de rayonnement (150).
