    摘要： A simplified two-light valve configuration for high performance projection displays which eliminates much complexity and the costs associated with three-light valve projection displays, such as a crossed dichroic beam splitter cube, a long retrofocus projections lens, and the additional cost and complexity of a third light valve. Two reflective liquid crystal light valves are positioned and aligned relative to each other on two adjacent surfaces of a polarizing beam splitter cube. Illumination is introduced through a third face of the cube, and a projection lens images the two light valves through a fourth surface of the polarizing beam splitter cube. Color-sequential and alternating polarization states are provided by a color filter wheel or cage containing individual facets of dichroic or color glass filters, such that as the wheel or cage rotates, the filters change and produce sequential red, green and blue outputs. In addition, the polarization of adjacent colors is alternated by adding a polarizing film onto each color filter.

    摘要： A light guide system has a light guide having a first end portion opposite a second end portion. The light guide provides a first surface and a second surface between the first and second end portions, and the second surface is inclined relative to the first surface. A light source is disposed along the first end portion on a first axis. A light redistribution device is disposed on an entrance of the light guide for receiving light from the light source and redistributing a portion of the light perpendicular to the first axis to provide a uniform light distribution from the first surface.

    摘要： A method of fabricating a dielectric film comprising atoms of Si, C, O and H (hereinafter SiCOH) that has improved insulating properties as compared with prior art dielectric films, including prior art SiCOH dielectric films that are not subjected to the inventive deep ultra-violet (DUV) is disclosed. The improved properties include reduced current leakage which is achieved without adversely affecting (increasing) the dielectric constant of the SiCOH dielectric film. In accordance with the present invention, a SiCOH dielectric film exhibiting reduced current leakage and improved reliability is obtained by subjecting an as deposited SiCOH dielectric film to a DUV laser anneal. The DUV laser anneal step of the present invention likely removes the weakly bonded C from the film, thus improving leakage current.
