    Abstract: An optical film includes a plurality of alternating first and second layers. The first layers have a first in-plane birefringence, the second layers have a second in-plane birefringence, and the second in-plane birefringence is less than the first in-plane birefringence and greater than 0.03. The first layers may include polyethylene terephthalate homopolymer and the second layers may include glycol-modified co(polyethylene terephthalate). The optical film has a shrinkage along a first direction of greater than 4% and a shrinkage along an orthogonal second direction of greater than 3% when heated at 150° C. for 15 minutes. A glass laminate is prepared by disposing the optical film between glass layers and laminating the optical film to the glass layers.

    Abstract: A partial reflector including a plurality of optical repeat units where each optical repeat unit includes first and second polymer layers is described. A refractive index difference between the first and second polymer layers along a first axis may be Any, a refractive index difference between the first and second polymer layers along an orthogonal second axis may be Δƒχ, where |Δηχ| is at least 0.1 and |Δny| is no more than 0.04. The optical repeat units may have a smallest optical thickness T1 proximate a first side of the optical stack and a largest optical thickness T2 proximate an opposite second side of the optical stack, where (T2−T1)/(T2+T1) is in a range of 0.05 to 0.2, and T2 is at least 350 nm and no more 1250 nm. The partial reflector may be used in a circular polarizer for correcting color shift with view angle in a display.

    Abstract: The disclosure relates to emissive displays and, in particular, to emissive displays that include a top surface (111) that has a diffusely reflective inactive surface (116) adjacent a diffusely reflective emissive surface (114). The emissive display further includes a polarization selective antireflection film component (120) that includes a linear absorbing polarizer (126), a reflective polarizer (124), and a quarter-wave retarder (122), and is positioned separated from the top surface. The disclosure also relates to issues arising from these antireflection film components, such as brightness efficiency loss and image degradation such as pixel blur. The enhanced antireflection stack performs well in commercial OLED displays, with a 20% or greater brightness gain, a 30% or greater ambient light reflectance gain and no visually apparent image degradation.

    Abstract: 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.
