Tech-On were in the Delta Electronics booth during Display Taiwan 2011 in Taipei this week, and they found a couple goodies. The image above shows Delta's plans for the epaper screens that they have developed in partnership with Bridgestone.
In addition to the 32" color screen, they also plan to offer a 10" flexible screen in 2012. None of the screens are in production, though.
You can also get the 13" unit that I showed you at CES 2011 as a development kit. it has pretty impressive specs, IMO. It comes with an API which will help reduce development time.
