IBM Takes Another Step Towards E-Paper.
In the journal Nature, IBM researchers said that they had developed flexible transistors made out of very thin layers of the organic compound phenethylammonium combined with tin oxide that can be laid down on plastic. The transistors conduct electricity at much lower heat levels than amorphous silicon displays, meaning that a flexible plastic mounting can be used. The manufacturing process is also much cheaper and can be done at room temperature.
However, IBM is not the only company working on electronic paper. Lucent Technologies Inc and E Ink Corp are also developing an electronic display using plastic transistors from Bell Labs and 'electronic ink' from E Ink. Neither company is prepared to hazard a guess on when electronic paper might migrate from the labs to market.
