From Air Traffic Control to LCD Module: Evolution of Capacitive Touch
Capacitive touch is the pioneer of touchscreen technology, dating back to the mid-1960s and paving the way for other succeeding technologies. It remains the most widely used touchscreen technology today, from LCD module displays to consumer tablets and smartphones. Before all these, however, capacitive touch helped to keep air travel safer. Eric Arthur Johnson designed the first touchscreen in 1965 at the Royal Radar Establishment in the U.K. for air traffic control. The device naturally was a far cry from today’s touchscreens. The first models could only process commands one touch at a time. By today’s standards, certainly not quite ideal for the task of coordinating with dozens of planes in airspace.
