    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： 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%.

    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： In a new packaging method for light management films in displays, such as liquid crystal displays, a stack of two or more optical films is held together before insertion into the display frame. The stack includes at least two of the films that are adhered together using adhesive positioned outside the viewing area of the films. In some embodiments, the adhesive is provided at one or more tabs provided around the periphery of the film stack.

    摘要： Color transmissive displays have historically used only backlight for forming the color image, and have not used ambient light. Usually, such a display is not used in bright sunlight, since the color image becomes washed out. Transflective color displays form an image by reflecting ambient light or by transmitting backlight, and can be used in bright sunlight. The transflector in such displays reflects the ambient light while also transmitting the backlight. The requirements on the transflector, however, are different from those used in monochromatic displays. According to the invention, a color transflective display device uses comprises a transmissive display unit having a viewing side and a back side and defining picture elements. A structured transflector is disposed to the back side of the color display unit. The structured transflector includes a structured surface and a layered dielectric reflector disposed over the structured surface.
