A method for forming a display device including generating a face plate element by providing a first substrate with a photoactive resin thereon and exposing the photoactive resin to a light interference pattern formed by three collimated and coherent light sources, resulting in columnar features. A display device including an optical display element and a polymer face plate that receives or directs light to the optical display element. The face plate includes columnar areas where an index of refraction of the columnar areas is different from the index of refraction of a cladding area surrounding the columnar areas. The columnar areas are formed by exposure of a photoactive resin to a light interference pattern formed by three collimated and coherent light sources. A method of manufacturing a wave guide including providing a first substrate with a photoactive resin thereon and creating a wave guide channel in a wave guide template. The wave guide channel is filled with a liquid crystal material that is exposed to a light grating to create a variation in an index of refraction of the liquid crystal material in the wave guide channel.

A polarizer is formed with an arrangement of polymer fibers substantially parallel within a polymer matrix. The polymer fibers are formed of at least first and second polymer materials. At least one of the polymer matrix and the first and second polymer materials is birefringent, and provides a birefringent interface with the adjacent material. Light is reflected and/or scattered at the birefringent interfaces with sensitivity to the polarization of the light. In some embodiments, the polymer fibers are formed as composite fibers, having a plurality of scattering polymer fibers disposed within a filler to form the composite fiber. In other embodiments, the polymer fiber is a multilayered polymer fiber. The polymer fibers may be arranged within the polymer matrix as part of a fiber weave.

Optical devices using reflective polarizers and, in particular, diffusely reflective polarizers are provided. Many of the optical devices utilize the diffusely reflecting and specularly transmitting properties of diffusely reflecting polarizers to enhance their optical characteristics. The optical devices include a lighting system which uses a reflector formed from a diffusely reflecting polarizer attached to a specular reflector. Another optical device is a display apparatus which uses a diffusely reflecting polarizer layer in combination with a turning lens which folds shallow angle light toward a light modulating layer. Other optical devices exploit the depolarizing characteristics of a diffusely reflecting polarizer when reflecting light. Still other optical devices use diffusely reflecting polarizers to recycle light and improve display illumination.
摘要:
Optical films and processes for forming the optical films are described in which materials having different properties are used and the different properties are exploited to obtain improved optical and/or mechanical properties of the optical film. The different properties of the materials may be used to select processing conditions under which the materials will react differently. The film may be processed with respect to two different directions with the amount of molecular orientation, if any, induced by the process being separately controlled for each material and each direction.

Diffusely reflective articles manufactured from optical bodies including continuous and disperse phases are disclosed along with methods of manufacturing such articles. Also disclosed are underdrawn continuous/disperse phase optical bodies that are particularly well-suited to post-forming operations. The articles, methods and optical bodies of the present invention preferably allow for post-forming of the optical bodies while retaining desired levels of diffuse reflectivity in the articles formed from the optical bodies.

A dispersing element for a rear projection screen assembly is sensitive to the polarization of the light passing through the element. In particular, the element disperses light having a first polarization differently from light having a second polarization orthogonal to the first polarization. The dispersing element may be aligned with a polarization axis neither parallel nor perpendicular to the polarization of the light passing through the element. The dispersing element may also be employed with a polarizer to remove unwanted light that propagates through the dispersing element. The dispersing element may also be rotatably mounted relative to a polarized light source so as to vary the angle between the polarization axis of the element and the polarization direction of the light.

The present invention provides light valves including polarizing elements in which light transmission can be controlled by rotating at least one of the polarizing elements about an in-plane axis. Although reflective polarizing elements are preferred in devices according to the present invention to reduce the problem of heat build-up, the use of absorptive or other polarizers may also be envisioned. The polarizing elements may also include at least one reflective polarizer in combination with an infrared reflective material or an infrared absorptive material. The polarizing elements can be included in light valves to control light transmission by rotating at least one of the polarizing elements about an in-plane axis. The light valves according to the present invention may find use in any application in which the transmission of light (visible or otherwise) is to be controlled. Examples of specific applications include, but are not limited to: windows, luminaires, skylights, etc.
摘要:
A diffuse infrared communication link provides for communication directly between nodes each having a transceiver. A repeater may be present to facilitate communication. Each node is automatically reconfigurable between operation with or without a repeater. When a repeater is present each node automatically ignores any transmission by another node.
摘要:
The present invention is for a radiation transmitter which transmits radiation to an illumination spot for forming reflected radiation. The transmitter includes a plurality of radiation transmission sources. Each of the sources transmits to a portion of the illumination spot. The transmitter includes means for alternately activating a portion of the transmission sources to illuminate a portion of the illumination spot for aligning a radiation receiver to receive the reflected radiation.Each resident of network transmits in turn its address and the address of each resident that it recognizes. Once a prospective resident can recognize each resident of the network it announces that it is joining the network and states its new address and the address of each resident it can see. Every resident then amends its list of recognized residents to include the new member.
