CA 2338597

Large display apparatus includes a plurality of modular display units each having an image projector for projecting a section of a large composite display, and a light-transmissive screen located and dimensioned with respect to its projector to receive its respective section of the display in a slightly contracted form with respect to the overall display to be viewed, so as to leave a bare margin around the outer edge of a size such that the refraction of the light when transmitted through the screen will diverge the light to the outer edges of the viewing side of the screen, thereby minimizing mullions between adjacent screens without losing any part of the image content of the respective sections of the composite display.

Ce grand dispositif d'affichage comprend plusieurs unités modulaires d'affichage, possédant chacune un projecteur d'image, destiné à projeter une section d'un grand affichage composite, ainsi qu'un écran transmissif situé et conçu en fonction de son projecteur, de manière à recevoir sa section respective de l'affichage dans une forme légèrement contractée par rapport à l'entier affichage à visionner, et de façon à laisser une marge nue autour du bord extérieur, qui soit d'une dimension telle que la réfraction de la lumière, lorsqu'elle est transmise à travers l'écran, fasse diverger la lumière vers les bords extérieurs du côté vision de l'écran, ce qui contribue à minimiser les meneaux entre écrans adjacents sans perte d'aucune partie du contenu de l'image des sections de l'affichage composite.
