LCD? Plasma?? OLED??? Nano Based FEDs!
Field Emission Displays?! Ever hear of em? (I hadn't) but being a fringe science kinda person I stumbled across this and it sounds really impressive.
Nanotube based field emission displays - Sounds like something from 10 years from now? Well if Samsung has their way displays based on this technology will be on the shelves by the end of 2006!! They have a 30" prototype right now.
http://www.technologyreview.com/arti...nn1104.asp?p=1
It's a 5 page story so don't miss some of the most interesting stuff by just reading the first page. For example - 1 gram of nano-tubes is enough to cover the display area of SIX 30" displays - one tiny gram! How small is that? Well, it says 10,000 nanotubes will cover a single pixel! We're talking TINY stuff here!
Some of the other benefits:
?__Thin (in fact the story states its a mere 2mm thick)
?__Light
?__No burn-in
?__Viewable from any angle
?__Pixels switch quickly
?__Low power consumption (current 30" prototype draws 100 watts)
Fact is, anything 'nano-related' is really interesting to me and this seems goes far beyond what current nano-tech is involved with today.
Anyway... Enjoy!

Hi Dave
I think these have been researched for some time in the form of 'cold cathode' emission where each pixel featured its own phosphors and electron source. If that's the case, this development is an advance on the prior art. Sounds exciting.

I hope those Carbon nanotube based FEDs are capable of super high resolutions and be really really cheap, because Samsung's own CRT unit is producing a short-tube (15 inches) 32" CRT TV. That will easily short circuit demand for flat panel tech TVs...
Yep... page 5 of the story talks about the Vixlim tube (37" @ 14" deep - better pic than LCD or Plasma and up to 1/3 cheaper ETA next year) but the comments from the Samsung VP running this project said something like technologies will surly push each other and drive costs down.
Manufacturing cost per diagonal inch: (2005/2006)
Plasma: $9
FED: $7 (perhaps as low as $5)
As for resolution... its clearly supporting HD - "The image is as sharp as those produced by traditional high-definition picture tubes with similar display sizes..."
But the most interesting thing to me was 10,000 nanotubes PER PIXEL! The story went on to say something like due to the inexact science in creating and laying nanotubes some are broke and some aren't pointed in the right direction but we only need 30 to 50% of them to be 'okay' for the picture to come out looking the way it should. Imagine the day when those hurdles (production of and deploying of carbon nanotubes) are perfected. The displays using a technology like this could be turned into a super hi-def device one day!

I think you'll need to google on that to get more data.
I have read there is a US company selling these tubes by the gram and it is still very expensive. They are working on reducing production costs but still an inexact science. Still, this is really cool stuff!

"Carbon Nanotechnologies, a Houston-based firm with a considerable arsenal of patents in the field. A gram of carbon nanotube powder, enough to make half a dozen 40-inch displays, cost $100 last year, Kim says, but will sell for less than $10 in two years."
1 gram (enough raw material for 6 40" displays) sold for $100 last year is pretty impressive (~$17 per 40" display) but if Samsungs forecast is correct that same gram will sell for $10 in two years time. WOW talk about price drops! Bodes well for nano-tech going forward (~$1.66 per set).

P.S. I'm glad I finally extracted myself from "Political Outsider" - Tech is much more fun than politics and IMHO shouldn't be mixed.
I'm amazed at how little goes such a long way (1g builds multiple sets? wow!). $100/g is quite expensive (2835.xx/oz. just ain't cheap) but is cheap when you consider someone is lining up C molecules in tubelike formations at the atomic level.
Cool stuff indeed, and much more fun than listening to Scott, dmz, SDW2001, & others in PO.

Yea, that's why I said I was amazed at how such a little bit (1g) went such a long ways (covering multiple displays). That is really cool. Especially if it goes down to $10/g. At those kind of prices maybe we'll have displays that cover entire walls, like in Quaid's apartment in the beginning of Total Recall.
That would be awesome!

I will now bet on the chameleon Apple being a reality.
Also, a very small volume of vacuum is easy to degrade. A CRT has a vacuum chamber thousands of times larger and thus is far less susceptible to this.
I'm not trying to throw cold water on this, just pointing out some of the realities. FEDs have been researched long before nanotubes came into being. The previous idea was to use small diamond crystals as emitters. In cold Field Emission Gun electron microscopes they use tungsten crystals as emitters.
Personally, I think OLEDs have a stronger chance of being used in flat displays. They don't need a vacuum and are very easy to manufacture. The problem now, of course, is that they cannot be manufactured. There is as of now no suitable material for generating blue light that lasts long enough to be used in a consumer product.
Now I guess they should have banned me rather than just shut off posting priviledges, because kickaha and Amorph definitely aren't going to like being called to task when they thought they had it all ignored *cough* *cough* I mean under control. Just a couple o' tools.
Don't worry, as soon as my work resetting my posts is done I'll disappear forever.
Equally problematic, in his view, is the thermal expansion and contraction of the display. When the nanotubes are emitting electrons, the display gets hotter, and all its materials expand; when the electron beam is off, they shrink. ?The problem is how to accommodate the expansion,? Saito says. His team had to find materials whose thermal expansion coefficient was the same as that of glass, so that the entire display would expand and contract in concert.
Exactly how Samsung pulled all these pieces together is ?our secret,? says Kim.
From the story....
