How Smartphone capacitive touch-screens work
posted December 1 2014 20:39.41 by Giorgos Lazaridis

It is a nice video if you really do not know how smartphone touch-screens work. It's a combination of capacitive touch sensing technology and matrix arrays (follow the links for more info on each one).

Its interesting to learn though that the first capacitive touch screen was first used in CERN back in 1976, which makes this technology barely older than me!
