  • Liquid crystal alignment layers and method of fabrication
    Patent number: 10838258
    Abstract: Methods are provided for making layers with nano- and micro-patterned topographies by laser action or inkjet printing on a first surface. These topographies have a periodicity of 5 nm to 500 ?m in a first direction in the plane of the first surface. These layers can be used as anisotropically patterned alignment layers in electro-optical devices and generate an orientational order of at least 0.30.
    Type: Grant
    Filed: March 29, 2018
    Date of Patent: November 17, 2020
    Assignee: E-VISION, LLC
    Inventors: Anita Trajkovska-Broach, David Boyd, Dan Chambers, Joseph O. Branham
