Abstract

Procédé de réalisation d'un écran ou d'un autre type de surface réfléchissante ayant une courbure complexe. Ce procédé consiste à lier une pellicule métallisée à un support formable à chaud, de manière à former une feuille stratifiée. Cette feuille stratifiée, qui comporte au moins une face réfléchissante, est transformée en un écran à l'aide d'un outil concave ou convexe ayant la courbure complexe correspondante. Application en particulier à la réalisation d'écrans très lumineux ayant une surface réfléchissante.
