Indium

Indium was used to solve two main problems that stood in the way of lcd screens.

One of indium’s oxides enables conductivity and circuits without the use of wire. Doped with tin to form Tin Oxide (ITO), this ITO has 2 essential properties and is the ONLY material which, in the form of thin films (typically one hundreth of a micron thick) has a v.high electrical conductivity and is nearly completely transparent over the whole visible spectrum making it neutral in colour.
