Indium Tin Oxide (ITO) coatings are designed to produce an electrically conductive surface while maintaining high transparency in the visible spectral range. Due to the semiconductor properties of this material, ITO is also effective in reflecting long-wave IR radiation. With its dual characteristics of transparency and electrical conductivity in the visible range, indium tin oxide can be used in a wide variety of applications. Indium Tin Oxide serves well in preventing electrostatic discharge (ESD). Furthermore, it finds application as a heating resistor or for contacting electrical panels. Additionally, the ITO coating exhibits infrared radiation reflection properties. Due to its high refractive index, ITO boasts exceptional reflectivity. ITO coatings are also suitable for the electrical activation of liquid crystals in micro-displays.
If required, we can also apply a passivation layer of silicon dioxide SiO2 before coating with ITO. This very thin layer applied between the glass substrate and the ITO coating increases the electrical insulation. The layer also serves as protection, e.g. in LCD display applications, so that alkali oxides from the glass cannot migrate into liquid crystals.
