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.

Embodiments of methods and systems to generate an enhanced layered display system are described herein. In one embodiment, a method of generating an enhanced layered display system is provided including dispensing an optical bonding liquid onto a first substrate; forming an adhesive preform unit by curing the optical bonding liquid on the first substrate; and laminating the adhesive preform unit to a second substrate to form the enhanced layered display system, where one of the first substrate and the second substrate is a display.

Enhanced liquid crystal display system and methods

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.

Reconfigurable projection-screen system

A projection apparatus comprises a light emitting device (LED) and a cooling arrangement is described herein.

Projection LED cooling

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.

Method and system for dynamic gradient light filtering

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.

Projection device and screen

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.

Method and apparatus for adjusting relative disposition of projection optics based on operating conditions

A display device for displaying images in a rear projection display device is provided. The display device may include, amongst other structure, a screen including a lens portion and a frame portion. A tensioner may be operatively associated with the screen and may be adapted to adjust the frame portion to maintain a predetermined tautness in the lens portion.

Fresnel lens having reduced distortions

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.

Stabilizer for optical devices

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

A method of controlling power provided to one or more light emitting diodes in a projection system comprises measuring light output from the one or more light emitting diodes. Based at least upon the measured light output, the power to at least one of the light emitting diodes is modified.

LED control system with feedback

Embodiments of this invention include a system, method and apparatus for combining the light paths of a plurality of colored light emitting devices into a single light path with two reflecting devices and an optical combiner assembly in a projection system.
