Abstract: A reconfigurable projection-screen system. The projection-screen system includes a flexible screen and a frame assembly. The flexible screen includes a screen perimeter and a viewing region interior the screen perimeter. The frame assembly includes a plurality of frame members, where at least some of the plurality of frame members include a screen perimeter engaging portion. The plurality of frame members are selectively arrangeable in at least an assembled viewing configuration and a disassembled configuration. In the assembled viewing configuration the plurality of screen perimeter engaging portions extend the screen perimeter and hold the viewing region substantially flat. In the disassembled configuration the plurality of screen perimeter engaging portions allow the viewing region to fold.

Abstract: A front projection display device is provided including an image-generating source configured to generate an image, a wide angle lens system adapted to receive the image, and a screen. The wide angle lens system may be configured to increase distortion of the image in a first stage and decrease distortion of the image in a second stage. The screen may be configured to receive the image from the wide angle lens system on a first side and reflect the image back to a viewer on the first side. In another embodiment, a screen is provided for a front projection system, the screen may be configured to receive light from a steep angle and may include any number of surface topographies configured to reflect light back to the viewer along a desired viewing plane.

Abstract: A light filter for use in an optical system for displaying image. The light filter comprising, a substantially transparent substrate and an optical coating applied to the substrate. The optical coating is applied to the substrate such that a percentage of light being directed through the filter that is attenuated varies based on a position on the substrate on which the light impinges.

Abstract: A projection system. The projection system includes a projector, a projector holder, and, optionally, a screen. When included, the screen has at least a deployed configuration in which a viewing portion of the screen is substantially planar. The projector includes a wide-angle lens system to selectively project display images onto the projection screen or other viewing surface. The projector holder supports the projector and is moveable relative to the projection screen or other viewing surface. The projector holder has at least an operating position at which the projector is supported for projection onto the projection screen or other viewing surface.

Abstract: A system, method, and apparatus for sensing an operational condition of a projection device and generating a signal to be used in the adjustment of the relative disposition of a component of the projection device, are disclosed herein.

Abstract: An apparatus, system and method for stabilizing components is provided. In some embodiments, an apparatus for positioning an optical component relative to a frame is provided including a stabilizer. The stabilizer may be configured to be coupled to the optical component and the frame, wherein in a first configuration the stabilizer is configured to enable select adjustment of the optical component in at least two directions and in a second configuration a position of the optical component may be fixed.

Abstract: Embodiments of this invention include a system, method and apparatus for combining light paths of colored light sources through a common integration tunnel.

Abstract: A projection apparatus having three light source units optically coupled to an integrating tunnel. The three light source units to output three different color light bundles of different wavelengths into the integrating tunnel from a direction nonparallel to the output direction of the integrating tunnel.

Abstract: A projection apparatus that includes a light source optically coupled to an integrating tunnel to output light into the integrating tunnel through a first and a second medium from a direction nonparallel to the output direction of the integrating tunnel. The first and second mediums having different indices of refraction to facilitate reflection of the output light from the light source off a reflective surface of the integrating tunnel and propagating the reflected light substantially towards an output end of the integrating tunnel.

Abstract: A projection apparatus comprises a Light Emitting Diode (LED) and a cooling arrangement is described herein.
