viewsonic cde6561t 65 interactive touch screen.ITO is the English abbreviation for Indium Tin Oxide. It is a transparent electrical conductor. The properties of this material can be adjusted by adjusting the ratio of indium and tin, the deposition method, the degree of oxidation, and the size of the grains. A thin ITO material has good transparency but high impedance; a thick ITO material has low impedance, but its transparency becomes poor. When depositing on PET polyester film, the reaction temperature should drop below 150 ?? C, which will cause incomplete oxidation of ITO. In subsequent applications, ITO will be exposed to air or air barriers, and its unit area impedance will vary with Change of time. This makes resistive touch screens often need to be calibrated.
