I was just flipping through a copy of last months Photonics Spectra magazine tonight and came across this little article on OLEDs that can be used for e-paper and e-books. I believe it was Bell (it was one of the telecomm companies) that wanted to make a roll-up cell phone (a cell phone that can roll up like a fruit roll-up) and was wondering how you could possibly do that.
They basically have a active-matrix of organiec LEDs and InO nanowires as an active channel material for a transistor.
Anyways, for anyone interested, this was the first real exposure I had to OLEDs (organic LEDs) and it looks pretty cool.
