touch interactive.?? ITO , indium oxide, weak conductor, the characteristic is that when the thickness drops below 1800 Angstroms (Angstrom = 10-10 meters), it will suddenly become transparent, the light transmittance is 80 %, and the light transmittance will decrease when it is thinner At the thickness of 300 Angstroms, it rose to 80 %. ITO is the main material used in all resistive technology touch screens and capacitive technology touch screens. In fact, the working surface of resistive and capacitive technology touch screens is ITO coating.
