indium tin oxyde (LCD) (ITO)

Indium Tin Oxide, Indium Tin Oxyde (ITO), is an inorganic, transparent semiconductor consisting of approximately 90% indium dioxide and 10% tin oxide.

Indium tin oxide is used in photodiodes, LCD displays, OLED displays, touchscreens, plasma displays, touch-sensitive films, EL films, solar cells, and to shield electric fields and thus ensure electromagnetic compatibility( EMC).

In displays, indium tin oxide forms the transparent electrode on the viewer side, the anode, which is applied in strips to a glass plate or foil. In active matrices, the thin-film transistors are located on the indium tin oxide anode, which activate the individual color pixels and thus cause them to light up.
