The method for the fabrication of a curved back projection screen includes coating the screen before forming a sheet into the proper curvature. In one embodiment the sheet includes lenticulations to improve the perceived luminous intensity thereof. Through this method a back projection screen is provided that overcomes the manufacturing difficulties associated with previously known methods.

Méthode de fabrication d'un écran courbe pour la projection par transparence. Elle consiste à revêtir l'écran avant de donner à la feuille la courbure appropriée. Dans une application de l'invention, la feuille comprend des éléments lenticulaires afin d'accroître l'intensité lumineuse perçue. Grâce à cette méthode, il est possible d'obtenir un écran de projection par transparence et de surmonter les difficultés de fabrication liées aux méthodes antérieures connues.
