When applied over glass displays, these transparent conducting films make better touch screens for smart phones and tablet computers. They’re more electrically conductive than the films used now, which means better touch response; they prevent electromagnetic interference from other parts of the device, so you can run more applications at the same time; and they let more light through, which means a brighter display.
