  • Patent number: 12117636
    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.

  • Patent number: 12007593
    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.

  • Publication number: 20240027757
    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.

  • Publication number: 20230350119
    Abstract: An optical stack includes a reflective polarizer including a plurality of interference layers and an absorbing polarizer disposed on the reflective polarizer. The plurality of interference layers transmits at least about 85% of an incident light having a first polarization state, reflects at least about 80% of the incident light having a second polarization state, and transmits less than about 0.1% of the incident light having the second polarization state. The absorbing polarizer has a first transmittance for the first polarization state and a second transmittance for the second polarization state. An average of the first and second transmittances is greater than about 0.46. The second transmittance has a first standard deviation. The optical stack has a transmittance for the second polarization state having a second standard deviation which is less than the first standard deviation by at least about 10%. A display includes the optical stack.
