    Abstract: A multilayer optical film includes a plurality of alternating polymeric first and second layers numbering at least 20 in total. The polymeric first layers include between about 10% and 50% by weight of polyethylene terephthalate and between about 50% and 90% by weight of polyethylene naphthalate. For a substantially normally incident light and for a visible wavelength range, the multilayer optical film has respective average optical transmissions of between about 10% and 30% when the incident light is polarized along a first direction and greater than about 60% when the incident light is polarized along an in-plane orthogonal second direction. For a p-polarized incident light and for at least one wavelength in an infrared wavelength range, the multilayer optical film has optical transmissions T1 and T2 for respective incident angles of less than about 10 degrees and greater than about 40 degrees, wherein T2−T1 is less than about 40%.

    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: An optical system for displaying an image to a viewer includes a pixelated display including a plurality of pixels emitting unpolarized image light; a partial reflector having an average optical reflectance of at least 30% in a predetermined wavelength range; a first retarder layer disposed between the pixelated display and the partial reflector; a second retarder layer disposed between the first retarder layer and the partial reflector; and a reflective polarizer disposed between the first and second retarder layers. The reflective polarizer is adapted to increase a brightness of a pixelated image emitted by the pixelated display and displayed to the viewer by recycling at least a portion of unpolarized image light emitted by the pixels; and receive an image ray reflected by the partial reflector and reflect the received image ray toward the viewer.

    Abstract: An optical stack includes a reflective polarizer including a plurality of interference layers and an absorbing polarizer disposed on the reflective polarizer. The plurality of interference layers transmits at least about 85% of an incident light having a first polarization state, reflects at least about 80% of the incident light having a second polarization state, and transmits less than about 0.1% of the incident light having the second polarization state. The absorbing polarizer has a first transmittance for the first polarization state and a second transmittance for the second polarization state. An average of the first and second transmittances is greater than about 0.46. The second transmittance has a first standard deviation. The optical stack has a transmittance for the second polarization state having a second standard deviation which is less than the first standard deviation by at least about 10%. A display includes the optical stack.
