    Abstract: An aspect of the present disclosure provides for a quarter-wave retarder film that is overlaid onto a linearly-polarized stereoscopic image pair in an appropriate orientation in order to produce an image that is viewable using circularly polarized viewing glasses for increased viewing comfort and head-tilt resistance. Another aspect of the present disclosure enables the production of StereoJet-type ink jet images through the use of two separate single-sided clear polarizer substrates with the stretch orientation parallel to the running edge of the support layer. A further aspect of the present disclosure is directed to the production of laminated stereoscopic images in which the spacing of the image planes of the members of the image pair can be made in close proximity, farther proximity, or at an intermediate proximity to achieve desired optical, mechanical and/or visual results.

  • Publication number: 20100225832
    Abstract: A polarizing element includes a substrate with protruded threads, and metal thin wires provided on the protruded threads. Each metal thin wire includes a first thin wire provided to a first side surface of the protruded thread and a second thin wire provided to a second side surface of the protruded thread. Each first thin wire has a first volume. Each second thin wire has a second volume. Each metal thin wire has a third volume which is the sum of the first and second volumes. As a distance from one end of the substrate increases, the volume of each first thin wire decreases and the volume of each second thin wire increases so that the third volume is maintained within a predetermined range.
