Projected Capacitive: PCAP
The projected capacitive method allows simultaneous detection of two or more input points with high robustness and robustness. A light operating feeling and multi-touch gesture operations such as flicking, zooming in/out, and rotating, and a flat design that eliminates steps on the display surface are also possible. Sensitivity is improved by controller adjustment, and glove input is also possible. It has high performance in scratch resistance, weather resistance, design and so on.
Action principle
The electrodes are formed in a matrix shape, and adjacent electrodes are capacitively coupled to each other. When a conductive material (such as a finger) approaches the electrodes, capacitive coupling occurs between the finger and the electrodes, the capacitive coupling value between the electrodes changes, and the touch position is detected.
