E Ink smart screen puts a newspaper on your wall

What's here under discussion is contrast ratio - not contrast between the image and its surroundings, but contrast between the lightest and darkest tones that can be represented within the image itself. Another term would be "dynamic range", if that helps; "contrast ratio" is how the concept is typically expressed in the context of raster displays, so that's what I've gone with here.

Under either name, it's a major figure of merit for quality of image reproduction, and my point is that e-ink, being worst at it of any raster display technology of which I'm aware, is thus a very poor choice for displaying images if quality of reproduction is a criterion.

I know, and quality of photographic reproduction is not a criterion I would need from an eink display. My goal is subtlety. Honestly in a parallel universe I have probably built the same exact prototypes from the blog. My (defunct) startup was called Nitrogen Logic because technology should be as critical but invisible as the nitrogen in the air.

I am totally fine with an 8:1 contrast ratio if it gives me perfect integration into the ambient light :)

Photography would be displayed elsewhere, in a place that is meant to draw attention. I want eink because it shouldn't grab attention at all.
