GE builds an OLED Holiday Tree, makes mistletoe out of disused RAM
The R&D-types at GE have high hopes for their roll-to-roll OLED manufacturing process, but it looks like we have a couple years to wait before the tech is cheap enough to really catch on. In the meantime, what do we have for you? How about some super-expensive digiframes and a YouTube video of the world's first ever "OLED Holiday Tree?" Man, we hope those "War on Christmas" people don't catch wind of this one...[Via OLED Display]
European ROLLED project promises to print OLEDs on the cheap
Printed and flexible OLEDs aren't exactly uncharted territory, but a group of European organizations led by Finland's VTT Technical Research Center look to be taking things a bit further than most, and they're saying their material could eventually be cheap enough to be used in everything from product packaging to business cards. Helping things on that front is the use of regular roll-to-roll printing technology, which both lowers the cost of manufacturing the material and speeds up the production. The resulting material, which is still a tad mysterious, is apparently about as thick as three of four sheets of paper, and consists of organic sensors encapsulated in a moisture barrier film. According to the researchers, it could also be attached to sensors to measure the freshness of food contained in the packaging, or even be used as a copy protection measure. If all goes as planned, the researchers say the material could be put to commercial use in a "couple of years," and cost just a few cents for some applications.[Via OLED-Display.net]
Alps Electric shows off longer-life, printable OLED panel
Printable OLED panels are hardly the rare occurrence they once were, but Alps Electric seems to think it's worked enough magic with its latest prototype to stand out from the pack, even if it may not wind up in actual product form anytime soon. The key bit with this one, it seems, is a so-called "getter" layer that's used in addition to the usual electrodes and emission layer, which helps to seal the area around the cathode electrode and compensate for minute defects. According to the company, that effectively triples the life of the OLED panel, which is especially useful considering that the same technology is also increasingly being used for lighting systems in addition to displays.
