Iddo Genuth writes to tell us that Samsung and Unidym have shown the world's first carbon nanotube-based color e-paper. Interestingly, the new film is electrically conductive while remaining almost all translucent and only 50 nanometers thick. "The company also mentions that the EPD has momentous advantages over pedantic flat panel displays. EPDs have very low power use and bright light readability, which means that even under bright lights or sunlight, the user would be able to view the display clearly. Furthermore, since the device uses the thin CNT films, applications can include e-paper and displays with thin, flexible substrates. Power use is lowered due to the EPD's ability to reflect light and therefore able to defend text or images on the display without customarily refreshing."
