Abstract: A multilayer partial mirror includes a plurality of alternating first a second polymeric layers numbering at least 50 in total, disposed between, and integrally formed with, opposing first and second polymeric skin layers. For a visible wavelength range extending from about 420 nm to about 680 nm and an incident light propagating in an incident plane that includes a x-direction, and for an s-polarized incident light, the multilayer partial mirror has an average reflectance Rs1 for a first incident angle of less than about 10 degrees, and an average reflectance Rs2 for a second incident angle of greater than about 45 degrees, and for a p-polarized incident light, the multilayer partial mirror has an average reflectance Rp1 for the first incident angle, and an average reflectance Rp2 for the second incident angle. Each of Rs2/Rs1 and Rp2/Rp1 is greater than about 1.15.

Abstract: Multilayer optical films are described. In particular, multilayer optical films that include both birefringent high index layers and low index layers are disclosed. The low index layers can be a glycol-modified polyethylene terephthalate. These optical films can be reflective polarizers and may be particularly suitable for automotive, architectural, and industrial applications.

Abstract: A display system includes a display panel configured to emit a polarized image light having a first polarization state and at least one emission spectrum having a full width at half maxima (FWHM). The display system includes a reflective polarizer configured to receive and reflect the polarized image light as a first reflected polarized image light. For a first light incident at a first predetermined angle, the reflective polarizer has an average reflectance of greater than about 60% across the at least one emission spectrum for the first polarization state, a transmittance of at least about 50% for at least wavelength outside the FWHM of the at least one emission spectrum for the first polarization state, and an average total transmittance of greater than about 70% across a visible wavelength range including the FWHM of the at least one emission spectrum for an orthogonal second polarization state.

Abstract: Optical film stacks are described. More particularly, optical film stacks including a half-wave retardation layer are described. Achromatic half-wave retardation layers, including achromatic half-wave layers formed from a quarter-wave and a three-quarters-wave retardation layer, are described. Film stacks including reflective polarizers tuned to reduce wavelength dispersion of the half-wave retardation layer are also described.
