Carbon nanotubes used in computer and TV screens

A new kind of computer and TV screen, called a nano-emissive display or NED, is made from two sheets of glass, one covered by a layer of nanotubes standing on end, the other by a layer of blue, red or green phosphors. When charged, the nanotubes direct electrons at the phosphors, making them light up. Because the electrons have only a short distance to travel, an NED would use little power, says maker Motorola. more @ newscientist.com
