Patents by Inventor Hwansil JANG

Hwansil JANG 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).

  • TOUCH SENSOR AND IMAGE DISPLAY DEVICE INCLUDING THE SAME
    Publication number: 20220382403
    Abstract: A touch sensor includes a substrate layer, a plurality of sensing electrodes on the substrate layer, and at least one device hole penetrating through one or more of the sensing electrodes. A functional device of an image display device may overlap the device hole so that an optical interference by the touch sensor may be prevented.
    Type: Application

  • Conductive pattern
    Patent number: 11360612
    Abstract: Provided is a conductive pattern having at least one unit conductive pattern forming one touch pixel according to an aspect of the present invention. The at least one unit conductive pattern includes a plurality of nanostructures each having opposite ends. A ratio of nanostructures, both opposite ends of which are in contact with edges of the at least one unit conductive pattern to all nanostructures included in the at least one unit conductive pattern is 70% or more.
    Type: Grant
