    Abstract: Optical stacks including a first reflective polarizer and a partially reflective component are described. The partially reflective component may be a second reflective polarizer or a collimating reflector. The first reflective polarizer has a first average visible light reflectance for light polarized along the first block axis at normal incidence of at least 90 percent and a first average visible light transmittance for light polarized along the first pass axis at normal incidence of at least 85 percent. The second reflective polarizer has a second block axis and a second average visible light reflectance for light polarized along the second block axis at normal incidence being no more than the first average visible light reflectance minus 10 percent. The first and second block axes are not parallel and the first and second reflective polarizers have different f-ratios.

    Abstract: Multilayer reflective polarizers are described. More particularly, multilayer reflective polarizers having a higher block light transmission at longer wavelengths than shorter wavelengths while having a high pass light transmission are described. The described multilayer reflective polarizers may be combined with absorbing polarizers or used in display devices.

    Abstract: The present disclosure describes an optical stack that includes an asymmetric diffuser. As described herein, use of an asymmetric diffuser in an optical stack reduces undesirable defects in a display while maintaining optical gain and/or contrast of the display. The asymmetric diffuser is less diffusive along a first direction that is parallel with linearly extending structures of an associated light directing film

    Abstract: An optical system includes an extended illumination source configured to emit light from an extended emission surface thereof toward a display panel. The emitted light includes substantially distinct blue, green and red emission spectra having respective blue, green and red peaks at respective blue, green and red peak wavelengths, and corresponding blue, green and red full widths at half maxima (FWHMs). The blue FWHM extends from a smaller blue wavelength to a longer blue wavelength. The optical system further includes reflective polarizer disposed on the emission surface of the extended illumination source. The reflective polarizer includes a plurality of first polymeric layers. The optical system also includes an optical filter disposed between the reflective polarizer and the emission surface of the extended illumination source.

    Abstract: An optical stack includes an optical film (200) and an optical adhesive (500) disposed on the optical film. The optical adhesive has a major structured surface facing away from the optical film that includes a plurality of channels formed therein. The channels define a plurality of substantially flat land regions therebetween. The land regions include at least about 50% of a total surface area of the major structured surface. When the optical stack is placed on a support surface with the major structured surface of the optical adhesive contacting the support surface, the optical stack bonds to the support surface and may be removed from, or slidingly repositioned on, the support surface without damage to the optical adhesive or the support surface, and upon application of at least one of heat and pressure, the optical stack substantially permanently bonds to the support surface and the plurality of channels substantially disappear.
