There are many types of touch panel technologies available in the market, the popular types are resistive touch panel (RTP), surface capacitive touch panel, projected capacitive touch panel (PCAP or CTP), surface acoustic wave (SAW) touch panel, Infrared (IR) touch panel. The reason each type of touchscreen responds so differently is the underlying technology. In this article, we are going to discuss the two most widely used types, and compare resistive vs capacitive touch screen. Capacitive Touch Panel Projected Capacitive Touch Panel (PCAP) was actually invented 10 years earlier than the first resistive touchscreen. But it was no popular until Apple first used it in iPhone in 2007. After that, PCAP dominates the touch market, such as mobile phones, IT, automotive, home appliances, industrial, IoT, military, aviation, ATMs, kiosks, Android cell phones etc. Projected capacitive touchscreen contains X and Y electrodes...
