摘要： A light redirecting article redirects light toward a target angle. The light redirecting article is made from a material having a refractive index greater than 1.6. The light redirecting article has an input surface for accepting incident illumination over a range of incident angles and an output surface with a plurality of light redirecting structures, each light redirecting structure having a near surface and an exit surface for emitting an output light at an emitted light angle, wherein the exit surface is at an oblique angle relative to the plane of the input surface. For incident illumination at either of at least two different principal angles, each principal angle being greater than 60 degrees from normal and the principal angles having a difference of 5 degrees or greater, the emitted light angle is within 5 degrees of the target angle.

摘要： A projection display apparatus (10) uses a modulation optical system (200) that includes a liquid crystal device (210) in combination with a wire grid polarization beamsplitter (240), a wire grid polarization analyzer (270) and a projection lens (285) to form an image. In order to achieve high contrast and maintain high brightness levels, a compensator (260) is provided for minimizing leakage light for pixels in the black (OFF) state. A number of configurations are possible, such as with the compensator (260) disposed in the optical path between the liquid crystal device (210) and the wire grid polarization beamsplitter (240) and with a secondary compensator (265) disposed between wire grid polarization analyzer (270) and the wire grid polarization beamsplitter (240).

摘要： A system for creating a patterned polarization compensator (550) has a retardance characterization system (560) for optically scanning the spatially variant retardance of a spatial light modulator (210). A compensator patterning system (565) writes a spatially variant photo-alignment pattern on a substrate (555) of a polarization compensator. The patterned polarization compensator is completed by a process that includes providing a photo-alignment layer onto which spatially variant photo-alignment layer is formed, providing a liquid crystal polymer layer onto the photo-alignment layer, and then fixing the liquid crystal polymer layer to form a spatially variant retardance pattern into the structure of the patterned polarization compensator.
