We are practically neighbors with Polymer Vision, and I saw the device a few months ago, looks pretty neat. For those interested, check out my post about it.
Neat! There are some truly gifted people in your neighborhood then. Seriously, I am thankful for all your hard work. I digged some more and came up with a post from your blog (What makes our electronic paper displays different?) describing the controler in more detail:

Quote:
The E-paper controller
The waveform is software that needs to be controlled by a chip or ASIC (Application Specific Integrated Circuit). This ASIC controls all the switches of the matrix and in simple terms tells the pixel when it is activated. This together with the waveform tells the electronic ink when and how it has to make black, grey or white. This is the beating heart of the electronic paper display. For the iLiad, iRex Technologies has developed the Delta ASIC which in contrary to the industries standard E-paper controller is able to handle 4 bits gray scales (16 gray scales).
Now, of course I had to ask this: Why didn't you offer Polymer Vision to use the iLiad screen for the Readius rather than them using a tiny 5" display?
