摘要： A display (1000) including a display panel (130) and a polarizer (110) disposed to receive a light (150) output of the display panel (130) is described. The polarizer (150) may be a reflective polarizer (110) or a circular polarizer (100) incorporating a reflective polarizer (110). The display panel (130) includes a plurality of pixels and each pixel includes a plurality of subpixels. The reflective polarizer (110) has a first reflection band, wherein at normal incidence, the first reflection band has a long wavelength band edge wavelength between peak emission wavelengths of two subpixels in the plurality of subpixels. The reflective polarizer (110) may be disposed between an absorbing polarizer (106) and a retarder (108) in a circular polarizer (100). The reflective polarizer (110) may have substantially non-overlapping first, second, and third reflection bands.

摘要： Thermoplastic birefringent multilayer optical films are described. More particularly, thermoplastic multilayer films having alternating first and second layers having a linear layer profile where both outer layers are thinner than 350 nm but thicker than 150 nm are described. Thermoplastic birefringent multilayer optical films with thinner outer protective boundary layers are described.

摘要： The present disclosure is directed to optical bodies including a first optical film, a second optical film and one or more strippable boundary layers disposed between the first and second optical films. Each major surface of a strippable boundary layer may be disposed adjacent to an optical film or another strippable boundary layer. At least one of the first and second optical films may include a reflective polarizer. The present disclosure is also directed to methods of processing such optical bodies.

摘要： 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.

摘要： An integral optical stack includes a lens film having first and second major surfaces. The first major surface includes microlenses having an average peak-to-valley height PV1. A light absorbing layer is disposed on the lens film and defines a plurality of openings. A substantially planarizing optically diffusive layer is disposed on the first major surface of the lens film, conforming to the microlenses. The optically diffusive layer includes a plurality of nanoparticles. A polymeric material bonds the nanoparticles to each other to form a plurality of nanoparticle aggregates defining a plurality of voids therebetween. The optically diffusive layer has an average thickness greater than about 8 microns, and an index of refraction of less than about 1.25. Any non-planarity of a major surface of the optically diffusive layer due to the microlenses of the first major surface has an average peak-to-valley height PV2, PV2≤0.7 PV1.

摘要： A reflective polarizer has substantially distinct blue, green and red-infrared reflection bands for substantially normally incident light. A display system includes a display panel including blue, green and red light emitting pixels having respective blue, green and red peak wavelengths and respective blue, green and red FWHMs; and the reflective polarizer disposed on the light emitting pixels. The reflective polarizer: reflects at least about 60% of the incident light for each of the blue and green peak wavelengths and at least about 40% of the incident light for the red peak wavelength for a first polarization state; transmits at least about 60% of the incident light for each of the blue, green and red peak wavelengths for an orthogonal second polarization state; and has an absorption peak at a wavelength between the green and red FWHMs.

摘要： Optical bodies are disclosed that include a first optical film, a second optical film and at least one rough strippable boundary layer disposed between the first and second optical films. Also disclosed are optical bodies including a strippable boundary layer disposed between the first and second optical films and including a first polymer and a second polymer that is substantially immiscible in the first polymer. The present disclosure also provides methods of processing optical bodies that include stretching the optical bodies.
