There seems to be a new Eink-type display launching/about to launch. There are a couple of small companies (Topjoy and Reinkstone) saying that they're going to launch colour ereaders with these new displays.

GoodDisplay's new DES (Display Electonic Slurry) looks rather interesting. Like the original E-Ink it uses charged coloured (usually black) particles to form the display. Unlike E-ink, the cells containing the particles are aligned to the pixel electrodes, giving a sharper edge to the pixels. There's a PDF about the technology on their website which has a close-up comparison:

There also a rather poorly done slide in the PDF that suggests the B&W contrast ration of DES is 1:45. I can't find contrast figures for the latest E-Ink Carta 1200 display.

It looks interesting. If the claims of higher contrast and faster response times hold up. I look forward to hearing what they're like in real life when devices eventually ship.
