The invention relates to a projector screen for image projection, comprising a transparent support (16) which fixes the screen shape and a light-scattering layer, which covers at least one defined projection surface within the screen shape, whereby, in order to reduce the corona effect which degrades the image contrast and the image resolution, the light-scattering layer is embodied as a coating (18) on a very thin transparent film (17). Said film (17) is fixed to the separate support (16) and optically decoupled from the support (16), preferably by means of an air gap (19).
L'invention concerne un écran de projection destiné à la projection d'images. Cet écran comprend un support (16) transparent déterminant la géométrie de l'écran, ainsi qu'une couche dispersant la lumière, cette couche recouvrant au moins une surface de projection définie à l'intérieur de la géométrie de l'écran. Selon l'invention, pour réduire l'effet corona, qui altère le contraste et la résolution d'image, la couche dispersant la lumière se présente sous la forme d'un revêtement (18) appliqué sur une feuille (17) transparente très mince, cette feuille (17) étant fixée au support (16) séparé et découplée optiquement du support (16), de préférence par un intervalle d'air (19).
