New flexible films for touch screen applications achieve longer lasting display

Today, touch screens are everywhere, from smart phones and tablets, to computer monitors, to interactive digital signage and displays. Many touch screens are made of layered thin (billionths of a meter thick) films of indium-tin oxide, an inorganic material that is electrically conductive, which allows electrical signals to travel from the "touch" to the edges of the display, where they are sensed by the device—as well as optically transparent.
