Hi.

I am working on a nice electric motorcycle project and we are looking for an awesome instrument cluster display. E-paper (with backlight) would be a nice touch.

We can go in two ways with this:
1. buy a kindle and throw everything away, except display, backlight and touch. Obviously that would involve a design of new motherboard. Not too big a deal, but still.
2. buy a kindle, throw only the enclosure away, leave all the electronics.That would give as a running OS and possibly a good head start to create our dash app.

The main concern is about the display. I know there is a sequence to change pixel color, however, since we would only need black&white and would do segmented components (like a 7-segment digit display for speed), we would not mind any leftover shadows on the edges at all, it could be a design element...
So the question is: is it possible to get reasonably good refresh rates (200ms) when only few components are changed, and can it be done without the usual flickering? Is it possible in hardware at all, and if so, does the OS/drivers allow it? I believe our choice of options depends on that.
Thanks.
