Touch screen
General
The TFT LCD flat panel display is an XGA-compatible display which is
absolutely flicker free and low radiation. The screen module comprises of
a TFT-LCD colour screen, the TFT-interface and an inverter that
generates the voltage for backlighting the screen. As
an option the screens are available with Touch Screen including a
beeper.
Capacitive Touch Screen
The TFT Touch Screen works according to the principle of a change in
analogue 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 by the change in capacitance.
Because this takes place very quickly, the Touch Screen is optimally
equipped for a number of different requirements and applications.
The programming interface of the screen is identical to the mouse
interface.
