摘要： Beamsplitters are frequently used in projectors based on reflective liquid crystal display for separating input and output light, and more recently for color management systems. Rather stack filters are used in such systems to orthogonally polarize primary colors, converting polarizing beamsplitters to color splitters and combiners. Geometric polarization rotations induced by beamsplitters at moderate f-numbers have the effect of significantly degrading performance. Because retarder stacks in general rely on a specific input polarization to perform properly, such skew rays are responsible for color cross-talk. Retarder stacks designed according to the present invention are sensitive to the symmetries that exist between input and output polarizer configurations. These stacks provide the polarization transformations that will compensate for skew rays, such that normal incidence performance is maintained for all incident light.

摘要： Disclosed are color management architectures used in video projection systems including, for example, retarder stacks sensitive to the symmetries between input and output polarizer configurations that provide the polarization transformations that will comprise for skew rays, such that normal incidence performance is maintained for all incident light. Additionally, also disclosed are systems that utilize color selective polarization (CSP) filters and polarizing beam splitting elements such that an output analyzer is not required. One exemplary CSP architecture includes two CSPs, a single polarizing beam splitting element combination for splitting and combining light between two of the three panels, and an output polarizing beam splitting element used as an analyzer such that a single CSP is in the projection path. In all such architectures, an output CSP and clean up polarizer directly in line with the projection optics need not be included, thereby increasing transmission, improving imaging crispness, and reducing cost.

摘要： Generally, this disclosure concerns the angle sensitivity of polarization switch elements and the resulting impact of the ray direction on performance. More specifically, apparatus and techniques for compensating the angular sensitivity of liquid crystal (LC) polarization switches are described that enhance the performance of polarization switches. For example, a polarization switch is disclosed that transforms linearly polarized light of an initial polarization orientation that includes a first and second liquid crystal cell with a compensator located between the LC cells. The compensator layer is operable to enhance the field of view through the polarization switch. Such compensation techniques are particularly useful for short-throw projection environments.

摘要： A light source for sequential or scrolling displays that recycles otherwise unusable light. The recycling is achieved by reflecting that portion of the light spectrum that will not be used by a pixel back into the light pipe where the light is rehomogenized or redistributed. The rehomogenized or redistributed light may then be used by other pixels that can uses that portion of the light spectrum. The reflection or transmission of the light through a reflective polarizer is controlled by a polarization rotation element that rotates certain portions of the spectrum according to excitation.
