摘要： In a particular embodiment, the fractional coverage louver device includes a transparent layer of material having a first surface and a second surface parallel thereto. A plurality of louver members disposed within the transparent layer of material provide fractional reflective coverage across the width of the transparent material. The louver members are aligned to receive light entering the first surface at a shallow angle relative to the first surface and direct the light out the second surface at a high angle relative to the second surface, thereby increasing the angular viewing range. Transparent areas between louver members allow a portion of incident ambient light to pass through the louver device without being reflected back to a viewer. As such, the louver device has advantageous contrast properties.

摘要： Provided is a curved light guide screen. A plurality of vertically aligned light guides are arranged into light guide magnifying layers. Spacers are disposed between any two adjacent light guide magnifying layers, proximate to the magnifying output ends, to position the magnifying layers and define an orientation for the magnifying output ends. A curved viewing surface is defined having a concave, convex or complex curvature shape depending on the size, shape and positioning of the spacers. The spacers may have a variety of shapes, and may be flexible, semi-rigid or rigid. A case houses the light guide magnifying layers and spacers, as well as an image source and associated lenses. A related method of making a curved light guide screen is also provided.

摘要： In a particular, a high contrast projection system configured for front or rear projection includes a screen having a viewing side and a back side opposite thereto. The screen includes a transparent layer of material having louver members disposed therein to provide fractional reflective coverage across the width of the transparent material. The screen discriminates an image signal light from a source, such as a projector, from ambient light incident upon the viewing surface. The image signal light is redirected over a range of angles relative to a normal to the viewing side, while the majority of ambient light is directed generally toward the back side, for example passing through the transparent material between louver members. A light absorbing back panel adjacent to the back side absorbs the ambient light further improving contrast.
摘要翻译：特别地，配置用于前投影或后投影的高对比度投影系统包括具有观察侧和与其相反的后侧的屏幕。屏幕包括透明的材料层，其中布置有百叶窗构件，以在透明材料的宽度上提供分数反射覆盖。屏幕识别来自诸如投影仪的源的图像信号光与入射到观察表面上的环境光。图像信号光相对于观看侧的法线在一定范围的角度被重定向，而大多数环境光通常指向背侧，例如通过透明构件之间的透明材料。与背面相邻的吸光后面板吸收环境光，进一步改善对比度。

摘要： In a particular embodiment, the louver device includes a transparent layer of material having a first surface and, parallel thereto, a second surface. A plurality of shaped louver members are disposed within the transparent layer of material. The shaped louver members are aligned to receive light entering the first surface at a first angle relative to the first surface and direct the light out the second surface at a plurality of angles relative to the second surface.
