Abstract: A thin rear projection television using a wide angle lens system is provided. In an embodiment, a fresnel screen is used in which there are at least two spatial zones in the screen with different properties. The at least two zones may be adapted to compensate for the variation in input angle.

Abstract: An apparatus, system, and method for a luminaire with a light emitting device and a deformable reflector well is disclosed herein.

Abstract: A projection apparatus is formed employing a transparent optical element to receive a plurality of colored light bundles from a plurality of light sources along a plurality of optical paths and to emit the plurality of colored light bundles along a substantially common optical path due, at least in part, to refraction through the transparent optical element.

Abstract: 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.

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 Fresnel lens for a display device is provided. The Fresnel lens includes a first sloped surface angled to receive input light, a second sloped surface facing the first sloped surface, and a valley floor linking the first sloped surface to the second sloped surface. The valley floor may be configured to scatter stray light reflected from the first sloped surface.

Abstract: The ultra-thin rear projection display device described herein includes a lens system and one or more planar mirrors that are parallel to a screen on which an image is to be displayed. The screen may be a Fresnel lens having a plurality of bumps on the output surface to reduce the visibility of a stray light image. The Fresnel lens may have a diffusion layer on the output side of the Fresnel lens.
