Abstract: A glass laminate (100) including first and second glass layers (102,104), a reflective film (110) having opposed first and second major surfaces and disposed between the first and second glass layers (102,104) with the first and second major surfaces facing the respective first and second glass layers (102,104), a first adhesive layer (117) disposed between and bonding together the first glass layer (102) and the reflective film (110), and a second adhesive layer (119) disposed between and bonding together the second glass layer (104) and the reflective film (110) is described. The second adhesive layer (119) is thicker than the first adhesive layer (117) such that the first major surface of the reflective film (110) is separated from an outermost major surface of the first glass layer (102) by distance d1, the second major surface of the reflective film (110) is separated from an outermost major surface of the second glass layer (104) by a distance d2, and 0.05

Abstract: A windshield of a vehicle includes a reflective polarizer. The windshield is configured to receive and reflect an image light emitted by a display toward a passenger of the vehicle, such that for a substantially normally incident light, the windshield has first and second reflection spectra versus wavelength for the incident light polarized along respective first and second directions. The first reflection spectrum includes a plurality of reflection bands. Each of the reflection bands has a maximum reflectance R1max between 20% and 80%. Between each pair of adjacent reflection bands in the plurality of reflection bands, the first reflection spectrum has a minimum reflectance R1min between 5% and 25%. In the visible wavelength range, the second reflection spectrum has a maximum reflectance R2max and a minimum reflectance R2min, such that R2max and R2min are within 15% of each other.

Abstract: 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%

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: 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.
