New technology promises fast and bright e-paper displays

Researchers from the Novel Devices Laboratory at the University of Cincinnati developed a new e-paper technology based on plastic sheets coated with aluminum with pores that hide black ink behind them. To show a black pixel, the display pushes the ink through the pore and onto the front of the sheet.

The research already developed a first prototype - a 6" round display that features 150 ppi. The refresh rate is very fast - about 67 times a second. It has a very bright white background - due to the aluminum coating.

As we said, this technology was developed at the University of Cincinnati, and it's is being commercialized now by Gamma Dynamics (who is also working on adding color using roll-to-roll printing processes), but they say it is still years away from actual products.
