摘要： A reflective polarizer includes a plurality of first layers disposed on a plurality of polymeric second layers. Each of at least 30% of the first layers includes at least 30% by weight of an inorganic material. For an incident light incident in a plane and a first incident angle, the reflective polarizer and the first layers have respective average optical reflectances R3v and R1v in a visible wavelength range and respective average optical reflectances R3ir and R1ir in an infrared wavelength range, R1v 10%, when the incident light is polarized along a first direction; and for the visible wavelength range and for a second incident angle, the plurality of polymeric second layers has an average optical reflectance R2v(x) when the plane includes the first direction and an average optical reflectance R2v(y) when the plane includes a second direction, 5%

摘要： A heads-up display includes a windshield (10) with a standardized wedge profile and an embedded reflective polarizer (20) for p-polarised light and a display (40). The reflective polarizer is disposed between, and spaced apart from, opposing outermost first and second major glass surfaces (11, 12) of the windshield. The heads-up display forms a virtual image for viewing by the eye of a passenger. An image emitted by the display may include a first image ray emitted from a predetermined region of the display and incident on the outermost first major glass surface of the windshield at an angle of incidence greater than about 60 degrees, with at least 90% of the incident first emitted image ray polarized in a plane of incidence of the first emitted image ray.

摘要： Optical stacks are described. In particular, optical stacks including reflecting-absorbing polarizers and quarter-wave plates are disclosed. The optical core of the optical stack—which includes a reflecting-absorbing polarizer with at least one skin layer including polarizing dye—may be co-extruded or co-stretched.

摘要： An optical stack includes an optical film (200) and an optical adhesive (500) disposed on the optical film. The optical adhesive has a major structured surface facing away from the optical film that includes a plurality of channels formed therein. The channels define a plurality of substantially flat land regions therebetween. The land regions include at least about 50% of a total surface area of the major structured surface. When the optical stack is placed on a support surface with the major structured surface of the optical adhesive contacting the support surface, the optical stack bonds to the support surface and may be removed from, or slidingly repositioned on, the support surface without damage to the optical adhesive or the support surface, and upon application of at least one of heat and pressure, the optical stack substantially permanently bonds to the support surface and the plurality of channels substantially disappear.

摘要： 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.

摘要： A polarizer including an oriented polymeric first layer is described. The oriented polymeric first layer is preparable from a mixture of polyvinyl alcohol and crosslinker where the crosslinker is included in the mixture at 5 to 40 percent by weight based on the total weight of the polyvinyl alcohol and crosslinker. The oriented polymeric first layer is a substantially uniaxially drawn layer, in that for U=(1/MDDR−1)/(TDDR1/2−1), U is at least 0.85, with MDDR being a machine direction draw ratio and TDDR being a transverse direction draw ratio.
