Another e-paper technology looks promising

Ars Technica has a report on a new form of e-paper that could offer the same low power consumption rate as the e-ink used in current e-readers, but at a much higher refresh rate and better screen reflectiveness.
Gamma Dynamics’s e-paper screen uses layers of oil and pigment that can be induced to change places through an electrical voltage. It could offer a refresh rate of 50Hz, and possibly color eventually. (At the moment it works best in grayscale.)
The screen will reflect 75% of ambient light, rather than the 40% of e-ink or 30% of electrowetting, making it easier to read in brighter areas without needing additional power.
This looks like a promising technology, though I hope they figure out something else to call it. If everything that isn’t “e-ink” becomes “e-paper” things are going to get pretty confusing.
