Tiniest mobo for a e-ink reader ?

I'm looking for the TINIEST realistic motherboard and battery to make some kind of e-reader :
drive a 8" e-ink screen (normal refresh rate);
high polling rate for the digitizer (>= 180Hz);
display e-book on it (zoom, prev/next page, annotations);
4 hours of usage on battery will be fine. 2 will be ok (and unlimited if usb powered);
being able to run app is an option but not mandatory;
Do you know of some crazy projects (e-watch mobo + lvds driver) I could have a look at ?

Thank you. Weight of this e-reader is very good and it looks very capable. But my problem is more with the motherboard size. I got no problem with the weight or size of the screen. The problem is with the mother board that should be "apart" from the screen (ribbon)

The Open Book project is a complete, hackable e-reader with a 7" screen. It comes in two flavors, one utilizing a ATSAMD51 microprocessor, and the "Wing" version one utilizing an easier-to-solder Feather microcontroller. Check out the schematic and BOM, should give a good idea of what you're in for if you try to build your own (or, you could just go with the Open Book...)
