Abstract
Touch screen displays comprising at least one nanostructure-film, and fabrication methods thereof, are discussed. Nanostructure-films may comprise, for example, a network(s) of nanotubes, nanowires, nanoparticles and/or graphene flakes. Such films are preferably at least semi-transparent and relatively flexible, making them well-suited for use in a variety of touch screen applications.
