GE Announces a breakthrough in low-cost, organic LED (OLED) production



We found this over on inhabitat today..originally from the GE Blog

With all the issues facing the planet, man produced or not, we really like seeing new technologies like this being produced. I’ve been to India, and I’ve seen the good LED Lighting can do there. LED’s in the long run, are extremely cheap, and offer great lighting alternatives, with often better ambient lighting in my opinion. With new technologies like the ones that GE are working on with OLEDS, we quickly see this as becoming a viable alternative to regular light bulbs, cfl or otherwise.

From the Article:

Hey everyone. We have a big development in the lab to report.

Since the early days of OLED research, people have said that OLEDs could potentially be made at very low cost because they don’t require expensive semiconductor manufacturing techniques. The ultimate low cost fabrication method would be a continuous “roll-to-roll” process like what is done in newspaper printing. However, so far, no one has demonstrated that OLEDs can be made this way. So about 4 years ago, we set out to find out for ourselves whether it could be done. We found a partner company (Energy Conversion Devices or ECD) with great experience at making roll-to-roll equipment and together we were successful in winning a proposal that we submitted to a government agency (NIST) looking to help fund high risk technology development.

Our proposal was to build a research roll-to-roll line for making OLEDs and our deliverable was to show that OLEDs could be made on it. We’ve been working to make this happen for the past 4 years. This means that we’ve been working to develop OLED device designs and fabrication processes that are compatible with roll-to-roll processing and to design and build individual equipment modules and then integrate them into a working line. Because this had never been done before, we faced some real technical challenges – especially given our program time constraints that often meant we had to start designing machine modules before we had the device fabrication process completely figured out! Anyway, in the end it all came together and we were successful in making our deliverable. Here’s picture proof that we were able to make OLEDs using our roll-to-roll machine.

Going forward, we’ll be using this machine to try to move from manufacturing research to real manufacturing. Still a lot of process and machine development to go but our recent success has energized us to keep going!
