ITO and IMITO

Conductive and Transparent Coating

Indium-Tin-Oxide (ITO) is a widely used material for thin film coatings with electrically conductive and optically transparent properties. The reflectance of light on interfaces or surfaces of an ITO layer may be reduced considerably by integrating it into an anti-reflecitve multilayer – a so called Index Matched ITO (IMITO). The Materion Balzers Optics ITO is very dense and remarkably free of pinholes.

Benefits

Electrically conductive and optically transparent coating
High physical density of coating
Low specific electrical resistance
No pinholes
High environmental and temperature stability
ITO may be electrically contacted by Gelot™ busbars
(please refer to datasheet OBA011PE)

Applications

Electrode layer in LCD technology
Counter Electrode on Lid Glass for LCOS micro-displays
Electrode on Heater Windows
Electro-Magnetic Shielding (EMS)

LC Display (or LCOS Microdisplay) ITO (red line) is counter electrode for applying a voltage across Liquid Crystall (green area). Voltage impacts polarization of light and thus steers brightness of pixel.

Heater Window Electrical current across ITO layer (red line) heats the glass and prevents from condensing moisture on surface. Yellow lines are busbars for electrical contacting of ITO.
