  • Patent number: 9372353
    Abstract: A method for forming sunglass lenses with a predetermined optical gradient, namely a polarized gradient, transmissivity gradient or color gradient in which an ink jet printer is used to print a gradient pattern on an oriented sheet, with the ink jet printer being provided with a dye, in one embodiment a dichroic dye and in another embodiment an iodine dye. The printed oriented sheet is incorporated into a lens to provide the lens with the associated gradient.

  • Publication number: 20150261011
    Abstract: A method and apparatus for continuously forming a web having a gradient polarization characteristic for use in sunglasses or other optical applications includes drawing a vertically oriented web of molecularly oriented material through a dye bath at an angle to the bath such that the residency time in the bath varies from top to bottom of the web to establish a polarization gradient from 100% at the top of the web to close to 0% at the bottom of the web. This process also creates a minimum transmissivity at the top of the web and a maximum transmissivity at the bottom of the web for permitting viewing displays using sunglasses having lenses cut from the web by viewing a display through the bottom portion of the sunglass lenses.

  • Patent number: 9128302
    Abstract: In the manufacture of gradient polarized sunglasses an optical retarder is used in front of a portion of a polarized lens to destroy the linear polarization of incoming light to render that portion of the sunglass lens non-polarized, thus to permit viewing of polarized displays through that non-polarized portion of the polarized sunglass lens.

  • Patent number: 7251075
    Abstract: An optical stack includes an intrinsic polarizer, such as a K-type or thin KE polarizer sheet. Optically functional coatings are disposed on one or both of the surfaces of the intrinsic polarizer. The optically functional coatings include a hardcoat, a transflector coating, a reflector coating, an antireflection film, a liquid crystal polymer retarder coating, a diffusion coating, an antiglare film, a wide view film, and an electrode. An optical stack including an intrinsic polarizer and an optically functional coating may have a thickness of less than 25 microns.

  • Patent number: 6630970
    Abstract: A liquid crystal display structure includes a liquid crystal display cell having a front surface and a back surface. One or more intrinsic polarizers lacking protective coatings thereon, such as K-type polarizers and thin KE polarizer sheets, are disposed adjacent to the front and back surfaces of the liquid crystal display cell. Alternatively, thinly cladded or encased iodine polarizers are disposed adjacent to the front and back surfaces of the liquid crystal display cell. The liquid crystal display structure may be used in conjunction with other optical display elements to enhance the brightness and contrast of the liquid crystal display.
