Jiangsu Touch Explorer Photoelectric Co., Ltd. Is a wholly-owned subsidiary of Suzhou Touch Planet Co., Ltd. Is also a national high and new technology enterprise. Committed to the human-computer interaction technology research, production and sales. The principle of the projective capacitive touch film technology belongs to the projective capacitive screen. It is composed of two transparent thin films, with a grid matrix layer consisting of a layer of metal wires crisscrossed by X and Y axes. Each matrix forms an induction unit that can sense the touch of human hands. The touch signal is transmitted to the circuit control board connected with the touch film. The control board transmits the signal to the computer. The computer automatically calculates the position of the touch to form an effective touch response, which can replace the mouse or even surpass the mouse (multi-point). The projective capacitive touch film is the only new touch mode that can realize surface, transparency, waterproof, anti-fouling, anti-light interference, no border and touch through glass in all touch modes.
