Previously Applied Nanotech's carbon nanotube TV company, only had an intriguing low-res video (right) and very little else to show for their research. Now Applied has taken the first step to actually making some usable prototypes, by signing an agreement with Taiwanese manufacturer Da Ling to do manufacturing trials later this year. Carbon nanotube sets use tiny flexible tubes to display images, and Applied claims that their technology can produce HD-quality sets that could sell for less than comparable LCD or plasma models. Of course, it'll be at least two years until Applied and Da Ling actually produce anything that you might be able to buy, and by then we assume that you'll be able to get a 50-inch LCD for about $400.
