    摘要： A film construction (330) includes a broad band reflective polarizing film (312) that may be immersed in an ultra low refractive index medium (332, 334). The reflecting polarizing film is characterized by a pass axis and a block axis, and its reflectivity for white light of the pass state polarization increases with increasing incidence angle to provide a compressed or narrowed viewing cone selectively in one plane of incidence. In some embodiments, the plane of incidence associated with the compressed viewing cone is aligned with the pass axis. In other embodiments it is aligned with the block axis.

    摘要： A reflective film includes microlayers arranged into optical repeat units, each optical repeat unit including a negatively birefringent microlayer. The microlayers are tailored to provide the film with on-axis polarizing properties, such that normally incident light polarized along a block axis is substantially reflected and normally incident light polarized along a pass axis is substantially transmitted. On-axis transmission for the block axis may be 70%. The microlayers also provide the film with angularly dependent polarizing properties: p-polarized light incident in a block plane of incidence is substantially reflected at near-normal angles but substantially transmitted at an oblique angle. The film transmits unpolarized light incident in this plane more strongly at the oblique angle than at normal. The films can be used in direct-lit backlights, luminaires, and similar lighting systems for flux leveling to promote spatial brightness uniformity.

    摘要： A display device includes a display panel and a biaxial reflective polarizer having a plurality of layers characterized by a varying optical thickness. A majority of the layers of the biaxial reflective polarizer having a smaller optical thickness are disposed closer to the display panel than the layers having a larger optical thickness.

    摘要： The present invention is applicable to optical assemblies for use with direct-lit backlights that exhibit a lower transmission for light of normal incidence as compared to the transmission of light at higher angles of incidence, to accomplish a leveling effect of the light across the display. In one embodiment, an optical assembly includes a reflector having an internal Brewster angle and a reflective polarizer having orthogonal reflection and transmission axes. In another embodiment, a direct lit backlight assembly includes one or more lamps, a reflector having an internal Brewster angle, where a major surface of the reflector is facing at least one of the one or more lamps, and a light redirecting layer.
