The RPI researchers are also working with scientists who used nanotubes as adhesives, mimicking the structures that allow geckos to cling to walls. The extremely high surface area of the nanotubes creates enough friction to hold two surfaces together. One possibility that uses the flexible plastic is a souped-up version of Velcro.
The RPI work is part of a much larger research effort to combine nanotubes with polymers and other flexible materials. "Flexible nanotube-polymer films will find a large range of applications, not only for electronics, but also for sensing applications and even optical applications," says Liming Dai, professor of materials engineering and chemistry at the University of Dayton in Ohio, who recently developed a chemical sensor using nanotubes embedded in plastic. "It's an important area. Now is the time for people to push these things toward real applications."

No mention of CRT radiation levels with this new tech?
One of the (perceived by me at least) benefits of throwing away my old CRT monitors to switch to LCDs was to get away from two things:
1) pixels that were fuzzy (not true squares, forcing the eye to work harder than necessary)
and
2) higher levels of radiation blasting my eyes when using a CRT
Its hard for me to tell from the article if using nano-tube based CRT technology solves either of these two issues?
Are we going back to blindness accelerating CRT technology just to get to a flexible screen?

1) this isn't an LCD display, but a potential thin CRT
2) the benefits of both LCD and thin CRT are lower weight and much lower power consumption - plus the obvious benefits of thinness (freedom of placement, e.g.)
3) drawbacks of LCD are lower contrast, dimmer images with a slower refresh rate
4) the benefits of CRT are faster, brighter images with higher contrast
5) i'm not aware of any research suggesting that eyes 'work harder' on images with fuzzy pixels. Reality, after all, does not present itself to us as tiny perfect squares! There is actually less eye strain produced when anti-aliasing techniques are use to prevent jagged-looking images. I think the benefit of this thin-CRT technology might be to product extremely high-rez displays. This *would* have a positive impact on eye strain.
6)The nano-emitters in thin CRTs will be 'blasting radiation', but the emissions should be orders of magnitude below that of a traditional CRT.

I believe that the mechanism allowing geckos to cling to walls and ceilings is the Van der Waals forces between nanostructures on their feet and the surface in question. Friction does not play a roll to my knowledge.

I know that many of the biggies like Sharp and Sony are working on Field Emition Display (FED). The promise of this technology is Flat Screens at comparable prices and low power requirement. FED displays should be available by next year. Will this technology negate nanotube development?

If this stuff could be made in large enough addressable arrays with organic LEDs embedded in or above it you'd have the makings of that classic sci-fi element the Chameleon suit. All you'd need is a couple dozen tiny camera's (well within today's tech) and some routing/mapping hardware to route the video image 180 degrees around the suits exterior. Voila! It'd be terribly much like the cloaking tech from the movie "Predator"

Respected Sir/Madam,
As I am a Engineering student doing seminar on FLEXIBLE CRT DISPLAY with a great interest please send related matters to vinays_mail@yahoo.co.in
Thanking you in advance !

Would these be capable to display 3 dimensional pictures as well (Be able to display the 3d motion pictures?)
i need all the technical aspects of the flexible crt display for a swminar. please send the regading details

One of the best uses I can think of this is towards the advancement of prostetic limbs. With this sense of pressure it would give the user of an prostetic arm a sense of touch in the fake limb if it could be wired into the nervous system where the prostetic attaches.

creating nanotube energy
I would like to talk to all the parties involved in this article including Liming Dai, The individual researchers and the people at Rensselaer Polytechnic Institute (RPI), Northeastern University, and New Mexico State University. We have Altruistic Ventures to study and invent together. How 'bout it! :)
