    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： Portable front projection screens include: (a) a first panel having opposing primary outer and inner surfaces, the first panel having at least first and second portions that are foldable relative to each other so as to be oriented at an angle relative to each other in an open configuration and closed to a coplanar flat configuration; and (b) a second panel foldably attached to the first panel and having opposing outer and inner primary surfaces. The second panel inner surface comprises a high gain, high Ambient Rejection Ratio projection screen that extends over a major portion of the inner surface. In a closed configuration, the first and second panels reside adjacent and substantially parallel to each other. The first and second panels cooperate to open to a user viewing configuration whereby the second panel is substantially vertical with the projection screen oriented to face forward toward a user and the second portion of the first panel defines a substantially horizontal base with the first portion of the first panel angled upwardly and inwardly from the horizontal base toward the substantially vertical second panel.
