Capacitive touch film works:

The principle of projected capacitive touch foil technology belongs to projected capacitive screen. It is composed of two transparent thin films, with a grid matrix layer of X and Y axes crisscrossed by metal wires.Each matrix forms an induction unit that can sense the touch of human hands.Capacitive touch foil is the only new method that can achieve curved surface, full transparency, waterproof, anti-pollution, anti-light interference, no frame and touch through glass.
