  • 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: 20140360582
    Abstract: The present invention provides a photovoltaic device comprising metal and a poly(vinyl butyral) layer that incorporates a suitable amount of 1H-benzotriazole. When electrical bias is applied to the photovoltaic device, 1H-benzotriazole forms a barrier layer at the metal/poly(vinyl butyral) interface, which, for example, unexpectedly virtually eliminated the yellowing of poly(vinyl butyral) in photovoltaic devices comprising silver components.
