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: 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.

Abstract: An OLED display including a display panel and a color-correction component is described. A plurality of comparative display panels otherwise equivalent to the display panel but having one or more different optical thicknesses of OLED layers have a maximum white-point color shift from 0 to 45 degrees of WPCSC45 and a white-point axial efficiency of WPAEC. The plurality of comparative display panels defines a performance curve along a boundary of performance points. The OLED display and the display panel have respective maximum white-point color shifts from 0 to 45 degrees of WPCS45 and WPCS045 and respective white-point axial efficiencies of WPAE and WPAE0. WPCS045 and WPAE0 defines a performance point of the display panel to the right of the performance curve and WPCS45 and WPAE defines a performance point of the OLED display above or to the left of the performance curve. Methods of making the OLED display are described.

Abstract: Polarizer stacks are described. More particularly, polarizer stacks that include an absorbing polarizer and multiple reflective polarizers, including at least one collimating reflective polarizer are described. Such polarizer stacks are capable of emitted light that is both collimated and color neutral. Backlights incorporating such polarizer stacks are also described.

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: 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 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.
