Nanotech Brings Cheap Flat TVs From Diamond Dust 193
neutron_p writes "Nanotech scientists are going to develop new TV display technology made from diamond dust. It opens up the possibility of cheaper and more power efficient flat panel displays, for use in wide screen digital TVs and many other applications. Toshiba recently announced plans to launch a television based on a new flat-panel display technology called SED (Surface-conduction Electron-emitter Display) in 2005. Sony and others have been working for several years on another technology called FED (Field Emission Display) but that too has yet to reach commercialization."

I guess it depends how perfect you want it.

Looks like they are using Diamond Like Carbon quite often... so its a quasi-zinc-blend structure apparently.
With field emission they are generating electrons so somehow the electrons get enough energy to reach the vacuum level. I wonder how efficient this is since diamond's bandgap is something like 5.5 eV.

Here's the original press release... (Score:5, Informative)
So here's some missing links: the press release at Bristol [bris.ac.uk], the diamond group at bristol [bristol.ac.uk] and the home page of Advance Nanotech [advancenanotech.com].
As you can see, that's a chemical vapor deposition group, so there's no need to grind up diamond dust from real diamonds.
