Capacative Touch Screen (Option)
General
The TFT Touch Screen works according to the principle of a change in
analog capacitance. It has a glass screen with a transparent, thin-film
overlay on the surface. This is fully sealed and protected by a further
layer of clear glass. Electrodes on the edges of the screen provide a
uniform low-voltage field. As soon as you touch the screen with your
finger the contact point is “recognized” by the change in capacitance.
Because this takes place very quickly - 15 milliseconds after being
touched - the Touch Screen is optimally equipped for a number of
different requirements and applications.
