Abstract

L'invention concerne un afficheur à fibre optique non plat servant à transférer une image projetée depuis un projecteur jusqu'à un écran au moyen de fibres optiques. Une pluralité de panneaux transparents est regroupée dans un cadre, de façon à constituer l'écran d'affichage. Le panneau transparent consiste en un panneau incurvé, étant donné que le matériau qui le constitue est flexible, les extrémités des fibres optiques sont couplées aux surfaces intérieures des panneaux transparents. Ces derniers peuvent être accouplés aux cadres selon une certaine forme afin de créer un afficheur non plat pouvant ainsi s'adapter à différentes situations.
