Reply to comment by pnlrogue1 in Hisense Hi Reader Pro is an Android smartphone with a 6.1 inch E Ink display (pre-order 250$) by giuliomagnifico

That's pretty neat. Something else that would be cool would be having the eink panel sit on top of an LCD. Then just turn off the LCD and output to the eink. Afaik, eInk panels are transparent or can be made so when they have no ink on them.

I think some smart watches do this (use eInk for the always on time and OLED otherwise) and it's really neat.

Or maybe a dot matrix top display

The only problem with that idea is this one:

  1. Send something to the e-ink.
  2. Battery dies before you finish what you're doing and the phone shuts off.
  3. No battery/phone shutdown means the e-ink never appears and you lost the benefit of being able to save something for when the phone's dead.

Surmountable problem (and probably a rare issue anyway) but would be irritating if you were in that situation where you don't realise your battery is so low so your phone shuts down before turning on the e-ink!
