    摘要： Light directing film is disclosed. The light directing film includes a first structured major surface and an opposing second major surface. The first structured major surface includes a plurality of unitary discrete structures. Each unitary discrete structure includes a light directing portion that is primarily for directing light and includes a plurality of first side facets. Each first side facet makes an angle with the plane of the light directing film in a range from about 35 degrees to about 55 degrees. Each light directing portion also includes a first base that is defined by the plurality of first side facets and has a first minimum dimension. Each light directing portion also has a first maximum height. Each unitary discrete structure also includes a bonding portion that is primarily for bonding the light directing film to a surface. The bonding portion is disposed on and between the plurality of first side facets and includes a plurality of second side facets. Each second side facet makes an angle with the plane of the light directing film greater than about 70 degrees. The bonding portion also includes a second base that is defined by the plurality of second side facets and has a second minimum dimension less than about 10% of the first minimum dimension. The bonding portion also has a second maximum height. The ratio of the second maximum height to the second minimum dimension is at least about 1.5.

    摘要： Optical stack is disclosed. The optical stack includes a light redirecting film that includes a first structured major surface that includes a plurality of unitary discrete structures. The optical stack also includes an optical adhesive layer that is disposed on the light directing film. At least portions of at least some unitary discrete structures in the plurality of unitary discrete structures penetrate into the optical adhesive layer. At least portions of at least some unitary discrete structures in the plurality of unitary discrete structures do not penetrate into the optical adhesive layer. The peel strength of the light redirecting film and the optical adhesive layer is greater than about 30 grams/inch. The average effective transmission of the optical stack is not less or is less than by no more than about 10% as compared to an optical stack that has the same construction except that no unitary discrete structure penetrates into the optical adhesive layer.

    摘要： A passive daylight-coupled display having an LCD panel, a diffuser, and a curved reflector behind the LCD panel. For passive backlighting, the diffuser transmits daylight to the reflector, which reflects the daylight to the LCD panel and provides for substantially uniform distribution of the daylight on the LCD panel for backlighting it. An N-stack daylight-coupled display includes a plurality of passive backlights cascaded in a stack for backlighting of LCD panels or static display panels. One N-stack display can include an active light source to provide light to the reflectors, and a secondary light source to provide light to at least one of the reflectors to provide backlighting of the display in low lighting conditions. A collapsible daylight-coupled display includes a daylight-coupled backlight that is collapsible when not in use for hand-held or portable display devices.

    摘要： The present invention includes electronic devices having liquid crystal display modules and repositionable front polarizers. A viewer views the display module through a front polarizer, which can be repositioned to change the display appearance, enhance the display contrast, invert the image, increase ambient light exposure, provide privacy, or the like. Repositionable front polarizers can be tiltably and/or rotatably mounted in front of the display module, or can be remotely located, for example on a pair of polarizing eye glasses. The present invention also includes reflective liquid crystal displays that have internal front light guides disposed between a liquid crystal cell and a front polarizer. As such, the light from the front light guide can illuminate the liquid crystal cell without being attenuated by the front polarizer, resulting in a brighter front lit display.

    摘要翻译： 本发明包括具有液晶显示模块和可重新定位的前偏振器的电子装置。 观看者通过前偏振器观看显示模块，其可以重新定位以改变显示外观，增强显示对比度，反转图像，增加环境光曝光，提供隐私等。 可重新定位的前偏振器可以倾斜和/或可旋转地安装在显示模块的前面，或者可以远程定位在例如一对偏光眼镜上。 本发明还包括具有设置在液晶单元和前偏振器之间的内部前导光体的反射型液晶显示器。 这样，来自前导光板的光可以照亮液晶元件而不被前偏光器衰减，从而形成更亮的前照亮显示。

    摘要： A polarizer has low color shift and is particularly well suited to use in an LCD display. The polarizer has a double pass color shift of |&Dgr;x|≦0.005 and |&Dgr;y|≦0.005 for illumination by a C-illuminant, and a double pass contrast modulation of at least 90%. The display includes two or more layers stacked together, at least one of the layers being an absorbing polarizer having a double pass color shift of |&Dgr;x|≦0.005 and |&Dgr;y|≦0.005 for illumination by a C-illuminant. A polarizer with a selected color shift is also used with a rear projection screen having a dispersing layer stacked together with first absorbing polarizer. The polarizer has a single pass color shift with at least one of &Dgr;x and &Dgr;y being negative under illumination by a C-illuminant, and a polarization co-efficiency greater than 90%.
