OLEDs Reach Milestone

A demonstration of the world's first roll-to-roll manufactured Organic Light Emitting Diodes (OLEDs) at GE's Global Research Center in Niskayuna, NY.

GE Global Research, the centralized research organization of General Electric (NYSE: GE), and GE Consumer & Industrial, today announced the successful demonstration of the world’s first roll-to-roll manufactured organic light-emitting diode (OLED) lighting devices. This demonstration is a key step toward making OLEDs and other high performance organic electronics products at dramatically lower costs than what is possible today.

OLEDs are thin, organic materials sandwiched between two electrodes, which illuminate when an electrical charge is applied. They represent the next evolution in lighting products. Their widespread design capabilities will provide an entirely different way for people to light their homes or businesses. Moreover, OLEDs have the potential to deliver dramatically improved levels of efficiency and environmental performance, while achieving the same quality of illumination found in traditional products in the marketplace today with less electrical power.

“Researchers have long dreamed of making OLEDs using a newspaper-printing like roll-to-roll process,” said Anil Duggal, manager of GE’s Advanced Technology Program in Organic Electronics. “Now we’ve shown that it is possible. Commercial applications in lighting require low manufacturing costs, and this demonstration is a major milestone on our way to developing low cost OLED lighting devices.”

Duggal continued, “Beyond OLEDs, this technology also could have broader impact in the manufacturing of other organic electronic devices such as organic photovoltaics for solar energy conversion, sensors and roll-up displays.”

Product packaging in lights, the coming thing.

The LEDS are Coming

Seoul launches single LED package delivering 900lm at 10W without the poisonous mercury, which would be talked about until the cows came home if it weren't for the fact that CFLs fit the loony toons alarmist global warming agenda ... Odd how the agenda trumps safety isn't it? I can see the day when the mercury in CFLs enters the food chain through ground water contamination and then the fish, so it's coming, because don't you know 'w e got to do something to save the planet. Remember MTBE and how it was going to save us all, then the results came in from CA groundwater studies and ... now MTBE is banned and the very same government that mandated it's use is suing the gasoline companies for using it, go figure.

LEDs have made more sense from the beginning, it's only the government that does no wrong who can't seem to see that. Note the four seperate LED dies in an array of the package below.

Korean LED maker Seoul Semiconductor has announced the commercial release of its ultra-bright Z-Power P7 Series LED, which has entered volume production. Seoul claims that the new LED, which incorporates four chips in a single package, delivers record brightness of 900 lumens at 10 watts.

In comparison with a 60W incandescent lamp producing 660 lm with an efficacy of 11lm/W, the 10W P7 single LED package produces a luminous flux of 900lm with eight-fold higher efficacy of 90lm/W. This is also nearly one-and-a-half times higher than for compact fluorescent lamps (CFLs), which typically consume 15W and emit 924lm (an efficacy of 61lm/W).
