Abstract: Disclosed herein are light collectors for use in projection applications. The light collectors gather light from surface emitting sources (e.g., LEDs) of differing color (or same color in some embodiments) using input lightpipes. A light collection system splits the light into orthogonal linear polarization states and efficiently propagates the light by use of a polarizing beamsplitter (PBS) and a reflecting element. Further, the light collection system may efficiently homogenize the light using an output lightpipe in a lightpath from the output of the PBS and the reflecting element. In addition, the light collection system may present a single, linear polarization at the output through the use of a half-wave switch (LC cell) in some embodiments or ColorSelect filter in other embodiments. The light collection system may be integrated into a single, monolithic glass, plastic or combination glass/plastic assembly.

Abstract: A four-panel liquid-crystal-on-silicon (LCOS) projection display system utilizes four available ports of a beam splitter and polarization filter architecture to provide a four-color component image with an increased brightness and color gamut compared with typical three-color component images. The projection display system includes a light source, four light modulating panels, a light directing subsystem, and a projection lens. The light source is operable to generate light having four color components. Each of the four light modulators is operable to generate a respective image associated with the respective one of the four-color components. The light directing subsystem is operable to split the four-color components before modulation and recombine them after modulation, and each light modulator is located at a separate port of the light directing subsystem. The projection lens is operable to project an image of the modulated combined color components.

Abstract: , Provided are several apparatus and methods to attenuate illumination light in a projector. Illumination light may be attenuated by directing polarized light toward a liquid crystal (LC) attenuation panel. The panel selectively modulates some, all, or none of the polarized light passing through. The light from the panel is then directed toward a polarization device. The polarization device analyzes the polarized light, and allows or denies the light to pass therethrough based on the polarization of the light.

Abstract: An achromatic polarization switch (APS) acts on linear polarized light to provide orthogonal polarized output states over a range of visible wavelengths. In a first switching state, the APS is operable to pass light of a first polarization state therethrough. In a second switching state, the APS is operable to transform light passing therethrough to a substantially orthogonal second polarization state. Used in conjunction with orthogonal analyzing eyewear, left and right eye images are time-sequentially modulated in orthogonal polarization states by the APS to yield a stereoscopic 3D image sensation.

Abstract: A problem addressed is the temperature cycling induced delamination of retarder stacks or other optical devices in the high-temperature, high-luminosity environments of optical projection systems. Described is an optical compensator device that can maintain a high degree of performance in the demanding environment of projection display. A mounting process involves using a sealant between optically clear glass or ceramic substrate and low elastic polymer retarder film. The sealant may mitigate or prevent the degradation of the retarder film by acting as an oxygen barrier that seals the substrate and increases the lifetime of the device in high luminance.
