  • METHOD OF FORMING A TOP PLANE CONNECTION IN AN ELECTRO-OPTIC DEVICE
    Publication number: 20210247657
    Abstract: An electrical connection between the backplane and the light-transmissive front electrode of an electrowetting device is provided by forming an aperture through the top front electrode coupled and a substrate coupled thereto and subsequently introducing a flowable, electrically-conductive material into the aperture. The flowable, electrically-conductive material provides an electrical contact between the light-transmissive electrically-conductive layer and the backplane.
    Type: Application
    Filed: April 30, 2021
    Publication date: August 12, 2021
    Inventors: Matthew Joseph KAYAL, Steven Joseph BATTISTA, Richard J. PAOLINI, JR., Shyamala A. SUBRAMANIAN
