  • Patent number: 11947314
    Abstract: VHOEs with expanded acceptance angle ranges are described as well as various systems and methods for fabricating VHOEs with expanded acceptance angle ranges. The VHOE with expanded acceptance angle range may include two or more individual Bragg gratings. The two or more individual Bragg gratings have the same diffraction geometry but with shifted Bragg conditions. Having the same diffraction geometry means when light is incident on the VHOE including two or more individual Bragg gratings, the diffracted light from each of the Bragg gratings is co-linear or overlapping with the diffracted light from the other Bragg gratings. The Bragg condition for each of the Bragg gratings are shifted with respect to each neighboring Bragg grating by an amount up to the acceptance angle range of each individual Bragg grating.

  • Patent number: 11947136
    Abstract: The anti-Newton ring film of the present invention is manufactured by subjecting a liquid phase containing one or a plurality of polymers, one or a plurality of curable resin precursors, and a solvent to phase separation through spinodal decomposition in association with evaporation of the solvent to thereby form a phase-separated structure, and then curing the curable resin precursor to form an anti-Newton ring layer having an arithmetic mean roughness Ra of 30 nm or less. This film may have a parallel light transmittance of 90% or greater, a haze of 3% or less, and a transmission image clarity of 90% or higher as measured by an image clarity meter using an optical comb with a width of 0.5 mm. The anti-Newton ring layer may contain the polymer and the curable resin precursor at a ratio (weight ratio) of from 1/99 to 60/40. This film can effectively suppress the occurrence of a Newton's ring in a resistive touch screen, and can suppress glare even in a high-definition LCD and an organic EL display.
