Hi! my name is Diana and I love the initiative and ideas behind the fairphone, I don’t have one yet but I’m very interested. Now I wanted to bring in a new idea for develloping fairphones. I thought that using an e-ink or e-paper screen, like the screens they use on ereaders would be very usefull because it uses less energy and you wouldn’t have to charge it too soon.
I love the e-ink technology. We own 2 Kobo readers and a smartwatch (the latter doesn’t have e-ink but is low power).
E-ink has a few drawbacks:
Black/white (and gray). No colours. Try using your current phone or desktop with black and white contrasts (option in Accessibility).
Very low refresh rate, lower than any TV. Makes it not feasible for things like typing, browsing, IM. For emergency use of that, its OK though, but not regular usage.
Not sure if the screens can be capacitive or accurate.
