Photos How It Works
"This is our Kitty-Hawk," said Tobin Marks, a researcher from Northwestern University and another study author, referring to the first flight of a motorized airplane. Entire rows or columns in the display can produce green light as bright as in most commercial TVs, but the scientists can not yet illuminate individual pixels. Still, the team has been approached by car manufacturers and plans to license the technology to a small start-up company. They hope to have a large-scale prototype within five years. The adoption of transparent nanowire OLED displays will mirror that of liquid crystal displays, appearing first in watches and cell phone displays and growing into larger, television-sized displays, say the scientists. "If you asked me about this a year ago, I would have said this was way far out in the future," said John Rogers, a scientist at University of Illinois at Urbana-Champaign who was not involved with the paper. "But there is a lot of work that makes OLED technology very promising." The research appears in the April issue of Nano Letters. Related Links: Eric Bland's blog: What the Tech? |
