| 摘要 |
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 scree n shape, whereby, in order to reduce the corona effect which degrades the imag e 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 t o the separate support (16) and optically decoupled from the support (16), preferably by means of an air gap (19).
