Choosing the right touchscreen
Touchscreen technology has come a long way since it was first used in 1966 in a radar screen used by the Royal Radar Establishment (RRE) for air traffic control. Despite it being bulky, slow, imprecise and very expensive, it was in use until the 1990s. Since then, consumers have come to expect quick and responsive touchscreens, which are increasingly used in industrial environments. Here, Noel Sheppard, director of Distec Ltd, explains how companies can choose between projected capacitance (PCAP) and resistive touchscreen technologies.
