  • Patent number: 10852614
    Abstract: The present disclosure is directed to a method of forming a layered structure including a nanostructure layer having nanostructures. The method includes: forming a coating layer on the surface of the nanostructure layer, reflowing the coating layer, depositing one or more conductive plugs into the coating layer, and hardening the coating layer. The one or more conductive plugs each has a first portion configured to be placed in electrical communication with the nanostructure layer and a second portion not covered by the coating layer.

  • Patent number: 10324352
    Abstract: Various embodiments of the present disclosure are directed to structures comprising a nanostructure layer that includes a plurality of transparent conductors and coating layer formed on a surface thereof. In some embodiments, the coating layer includes one or more conductive plugs having outer and inner surfaces. The inner surface the plug is placed in electrical communication with the nanostructure layer and the outer surface forms conductive surface contacts proximate an outer surface of the coating layer. In some embodiments, the structure includes a polarizer and is used as a shielding layer in flat panel electrochromic displays, such as liquid crystal displays, touch panels, and the like.
