In fact, the technology behind the touch screen can actually traced right back to the 1940’s but it was only two decades later that it actually became feasible to use on a large scale. ATMs have been using technology since 1965 which is when E.A. Johnson invented the first finger-driven touch screen that actually used the same capacitive touch mechanism that is still used in cell phones and other devices to this day.
Although there are other types of touch screen technology such as resistive touch or multi touch technology, capacitive touch technology is the one that is preferred for mass produced consumer products. How is a Capacitive Touch Screen Made? Today, a capacitive touch screen works through the use of an ITO touch film that is attached to the screen.
