46 touch screen displays.The four-wire resistive screen is covered with two transparent conductive layers ITO (ITO: indium oxide, weak conductor) between the surface protective coating and the base layer. When the thickness is reduced to less than 1800 Angstroms (Angstroms = 10-10 meters) It will suddenly become transparent, and the light transmittance will decrease when it is thinner. It will increase again when it is 300 angstroms in thickness. It is the main material of all resistive and capacitive screens.) They are insulated with fine transparent insulating particles, and the two conductive layers are turned on by the pressure generated when touching, and the X and Y coordinates of the touch are obtained due to the change in the resistance value.
