Nanotech Brings Cheap Flat TVs From Diamond Dust
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."
Probably synthetic diamonds, you know, the ones made in high-pressure ovens that cost about $50 and are the bigger than a fist, and are great for this kind of stuff. There was an article on Wired a while back, which I think was also mentioned in /. about this technology. But since nanotech is being mentioned this time, then probably now the diamond dust is being created by nanobots?
Go hug some trees.

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.

Once again, the physorg honeypot grabs slashdot eyeballs. Physorg takes press releases and puts them up, with bad formatting, on ugly web pages... with no links to the original source.
:) It's also, um, not exactly what I'd call "nanotech"... unless you consider any product involving structures at the molecular scale (like, oh, wood, or portland cement) to be "nanotech".
So here's some missing links: the press release at Bristol, the diamond group at bristol and the home page of Advance Nanotech.
As you can see, that's a chemical vapor deposition group, so there's no need to grind up diamond dust from real diamonds.
