Lighting the GE Way

couple of pargraphs from article.

This isn't news to GE. Proving commercial viability becomes more important as OLEDs develop. Scientists do their part through a process called "toll gating," in which they incrementally tackle risks that a promising technology will turn out to be a dud. Right now, Duggal's team is at work on improving the brightness and duration of OLED lighting. In March 2004, they successfully demonstrated that their prototype could match a standard incandescent bulb's light output. But the ultimate goal is to produce an OLED about seven times better than that, superior to even fluorescents.

The other major hurdle is solving the production problems that would let you print OLEDs as you would a newspaper. OLEDs need to be hermetically sealed to work. Today that's accomplished by sandwiching the OLED material between two layers of glass. That's why it's premature to talk about roll-to-roll production. "In a way, those lines I plotted that showed the potential of OLEDs were deceptive, because there were things missing -- like manufacturing," says Duggal. "These are challenging problems. But we can either be scared by them or find a way to work around them."

ECD machine program with GE to end about 2007- September 25 that would make four years.
