Abstract
The general field of the invention is that of display systems comprising an image projector and an associated display screen, the said display system being designed to be used by an observer situated at a given location, the said display screen comprising two transparent and substantially parallel faces, the said display screen comprising, on at least one of its transparent faces, a plurality of regularly distributed light-scattering patterns. The image projector according to the invention illuminating the screen under a plurality of angles of incidence determined by the position and the size of the display screen, the said angles of incidence being centered on a mean angle of incidence, the scattering patterns comprise at least one scattering surface oriented in such a manner as to diffuse the light rays having at least the mean angle of incidence in one or more directions corresponding to the said given location of the observer. Several embodiments are described.
