Projected capacitive (PCAP) touch technology has just recently been scaled up for use in large format applications like the TSItouch interface. PCAP touch has been implemented in popular handheld devices such as smartphones and tablets for years. In a PCAP system, a touch point is detected when a finger or stylus comes in contact with the surface, signaling a change in the system’s electromagnetic field and capacitance.

This touch triggered change is then pin-pointed and converted to locations on an X/Y electronic grid. The system uses this point on the X/Y grid to determine the placement of the touch. The TSItouch PCAP interface features a seamless at front bezel design, allowing the monitor to be easily be wiped clean, eliminating having to worry about dust and dirt collection.
