There are reports that Nemoptic declared bankruptcy. That's a shame, they seemed to have very interesting technology. Hopefully someone will pick it up and continue development...
Nemoptic has developed the world's first display that combines a color OLED with a monochrome Bistable Nematic LCD (Binem). The idea is that you can choose whether you want to have an OLED displays, or a e-paper like display, depending on the application and lighting condition (this somewhat reminds us of Pixel-Qi displays).
A Binem display, which is patented by Nemoptic offers the optical performance of a normal Nematic display but is still retains the image even without any power (i.e. it is bistable, like e-paper). Nemoptic displays are suitable for e-readers and other applications. Nemoptic claims that their displays offer a very high reflectance, a good contrast and good colors. They can also be made on flexible substrates - which means that the OLED/Binem display can probably be made flexible, too.
Back in June. Nemoptic has demonstrated a Active-Matrix prototype.
