  • Publication number: 20240118541
    Abstract: A display system for displaying information is disclosed, the display system comprising a glazing that includes a first transparent rigid substrate, a second transparent rigid substrate, and an interlayer positioned between the first and the second transparent rigid substrates; a projector that emits light toward the glazing at three discrete wavelength ranges in the visible spectrum; and at least three narrow band rejectors, disposed in a vision area of the glazing, that selectively reject light within the three wavelength ranges emitted by the projector.

  • Publication number: 20240027761
    Abstract: Display systems for viewing information are disclosed, that comprise a glazing, one or more holographic optical elements which reflect light within three or more discrete wavelength ranges; and one or more narrow-band absorbers that selectively absorb light of the same wavelengths as those reflected by the holographic optical elements. Also disclosed are methods of preventing or reducing stray light artifacts resulting from reflection or transmission from one or more holographic optical elements.

  • Publication number: 20240004114
    Abstract: Display systems and methods are disclosed for displaying images, while preventing or reducing unintended viewing. A projector is provided that emits light toward a viewing surface at three discrete wavelength ranges to create an image. A light-absorbing substrate is also provided, disposed between the viewing surface and the unintended viewer, incorporating narrow-band absorbers that selectively absorb light within the three wavelength ranges, thus reducing or eliminating the image perceived by the unintended viewer.

  • Publication number: 20230305207
    Abstract: The present application discloses interlayers comprising half waveplate (“HWP”) films and head-up display systems incorporating the interlayers. The interlayers and head-up display systems are optimized so that the optical axis has an angle phi (?) relative to the axis formed from the p-polarization direction of a display light projected onto the plane of the HWP film. The optimized ? depends on the optical properties of the films.

  • Publication number: 20180298224
    Abstract: The invention is a method for producing cellulose ester and acrylic composite latex particles and to latex compositions prepared from the method. The cellulose ester and acrylic composite materials are prepared by dispersing at least one cellulose ester in water and incrementally adding at least one acrylic monomer to said dispersion in the presence of a polymerization initiator. Surfactants and solvents are optionally added to aid in the dispersion of the cellulose ester in water.
