摘要： 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.

摘要： The present application describes color management architecture for a three-panel projection system that utilizes color selective polarization filters (CSPF) and polarizing beam splitting elements. An exemplary embodiment describes a color management architecture with a dichroic input beam splitter and three polarizing beam splitters. An output polarizing beam splitter is used as an analyzer. The color management system architecture can isolate any color channel from those remaining whose separation and combination are then carried out by a single beamsplitting element. The disclosed embodiments also provide an improvement in the ANSI contrast. In some embodiments, an achromatic quarter-wave plate is used in combination with a color filter to block the light reflected from projection optics.

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 sequential color system with reduced or eliminated global temporal notching losses may be implemented with a buffered display panel. Fast global blanking and/or inter-field images may be used to reduce or eliminate the global temporal notching losses. When consecutive states of a pixel are “on,” an inter-field image may be displayed by maintaining the pixel in an “on” state instead of turning the pixel “off” and then turning the pixel “on.” This improves the color brightness and saturation. The display may be implemented with a color wheel or with a color switch.
摘要翻译：可以使用缓冲显示面板来实现具有减少或消除的全局时间切口损耗的顺序彩色系统。可以使用快速的全局消隐和/或场间图像来减少或消除全局时间缺口损耗。当像素的连续状态“开”时，可以通过将像素维持在“开”状态而不是使像素“关闭”然后转动像素“开”来显示场间图像。这提高了颜色亮度和饱和度。显示器可以用色轮或彩色开关来实现。
