CST Capacitive Touch Screen is a human-machine interactive interface comprised of a conductive-material-coated glass panel. Current is uniformed on the glass panel entirely. By touching a finger on the panel, current flows via the finger and the ratio of the current flow is computed in order to detect the touch location. Due to a simple and robust design, CST Capacitive Touch Screen fully exerts its capability without losing its touch performance in any harsh environment.
