About Indium

Indium is a soft, silvery technology metal primarily used as indium tin oxide, the transparent conductive coating essential for virtually all touchscreens, flat panel displays, and thin-film solar cells. It is produced almost entirely as a byproduct of zinc refining. Supply is highly concentrated in China, and there are currently no effective substitutes for ITO in display applications.
