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.

Hi. I noticed the little tiffs and wanted to comment.
In all actuality: black and white are NOT colors.
Black is all colors together and white is the absence of all colors.
In technology and art, there is a big difference between "black & white"(grayscale) and colors. Always has been. When I was growing up, the TV in my room was a black & white, the living room TV was in color.
Sorry but the resident crafter had to check in.
Note: even today some older movies are listed as black and white.
So yes, one does need to be specific when trying to do something technical.
As to backlight and frontlight,
They also work totally different. Again, it helps to be specific if doing something technical.
Otherwise, it turns into a battle of did you mean this or that because this and that are two wildly different things.
Good luck with your project.
