Projected Capacitive Technology (PCT) is currently the most world-advanced technology regarding capacitive screens construction. Application of PCT in the touch screen makes possible to operate multi-touch function – tracking from 1 to 10 touch points (or more) at the same time, depending on controller configuration. PCT provides very high precision and much higher resistance to various types of errors caused by e.g. dirt on the screen. Depending on the controller configuration, the PCT offers possibility to add new features such as increased electromagnetic resistance (EMC), glove touch and proper operation despite the presence of water on the surface.
