    摘要： Portable projection screen assemblies include a case comprising a flexible projector screen held on a roller, the screen has a high ARR and a high-gain and can be adapted for use in uncontrolled indoor ambient lighting conditions. The case is configured with releasably matable first and second housing members and a slidably collapsible frame that slides open in a side-to-side orientation and unrolls the projector screen to at least one predetermined viewing configuration and closes together to encase the screen and frame therein. The projector screens may be particularly suitable for use with low-lumen projectors.

    摘要： Portable projection screen assemblies include: (a) a roller housing holding a roller with a flexible projection screen; (b) at least one substantially laterally extending screen support arm attached to the roller housing, the at least one screen support arm being configured to hold an outer edge portion of the flexible projection screen when the projection screen is in a laterally extended configuration; and (c) an outer housing case having an interior cavity sized and configured to hold the roller housing therein in a storage configuration. The roller housing is hingeably or releasably attached to the housing case and resides substantially vertically above the outer case in an operative position, whereby the outer housing case defines a support base adapted to reside on a support surface.

    摘要： Light transmissive structures include a light transmissive substrate that includes optical microstructures. The optical microstructures have a geometric feature that is configured to reduce glare in light transmitted through the light transmissive structure. Moreover, the plurality of optical microstructures also have a geometric feature that is configured to vary randomly and/or pseudorandomly across the light transmissive substrate so as to diffuse light transmitted through the light transmissive structure. Related fabrication methods are also described.
