  • Back-projection screen
    Patent number: 7092158
    Abstract: The invention concerns a screen wherein elements distributed on a single and common diopter enable both collimating and micro-focusing by relecting the light beams projected on said screen; on said diopter can also be distributed elements acting by refraction. The inventive screen has only one main optical component, hence it is not expensive to produce. The invention is particularly applicable to very compact projection devices and to situations with high projection incidence angles.
