Patents by Inventor Christine Higgins

Christine Higgins has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11467397
    Abstract: Methods are described for forming polarized image films in which a displayed image changes depending on the state of polarization of a backside illumination source. Methods are also described for eliminating the leakage of unpolarized light through certain parts of the images resulting in unwanted visual artifacts in these images. Polarized dual graphic films achieving images with higher optical density and uniformity, minimum ghosting and mis-registration, can be made by a manufacturing technique that is faster, capable of higher production volumes, and that can produce polarized images at a lower cost. An exemplary method provides for forming a polarized image or pattern on an oriented substrate by using a negative patterned resist image or pattern formed by graphic arts techniques, followed by the imbibition of a dichroic dye or iodine ink to form a corresponding positive image in the areas not protected by the resist.

  • Patent number: 10675824
    Abstract: Methods are disclosed for forming polarized films and glasses having polarization efficiency that is varied in a predetermined design. In particular, such designs include monochrome and color polarization density gradients, where the non-polarized areas of films and glasses allow viewing of polarized displays without distortion. The methods include forming films and glasses that have visually uniform density while still incorporating polarization gradients. The disclosed methods also enable creation of polarization filters and glasses with increased optical density and reduced glare from multiple angles.
