Killer Touch Screens
So touch screens are made out of this stuff, which is very very rare. It is predicted that in 10 years the world’s supply will be depleted, due to all the hubbub about touch screens. And how the fuck are expected to just go back to keyboards and mouses? What are we, fucking barbarians?
The interesting thing is what people are doing to try and find an alternative.
“Perhaps the answer is not to cut out indium altogether, but make what we have go further. Tobin Marks and his colleagues at Northwestern University in Evanston, Illinois, have developed a material based on cadmium oxide with just a sprinkling of indium that is just as transparent as ITO and three to four times as conductive. The material is prone to corrosion, so needs to be sealed under a thin layer of ITO, but ends up being just 20 per cent indium compared with 90 per cent for ITO (Thin Solid Films, vol 518, p 3694).
That has the sound of a stop-gap solution. Unfortunately, it’s not that simple. First, cadmium is a highly toxic metal, requiring careful handling and disposal. Second, materials such as cadmium oxide are prone to cracking, a decidedly inconvenient property in a screen that is designed to be repeatedly prodded and poked.”
If all this toxic stuff started appearing in touch screens who the hell wouldn’t get poisoned?
BUM BUM BUUUUMMMMM
