OLED

Regular 128x32 0.96" OLED display is very cheap, about $1-1.5. Energy consumption is about 20mA on average:

E-ink

Corne-ish Zen uses E-ink (Sharp GDEW0102T4). Nice!view uses LCD (Sharp LS011B7DH03), see discord (@Nicell: always been the sharp display. I tinkered with the epaper, but was never happy with the performance so never released it as a product).

LCD

Careful with the screens, there are screens for direct soldering, they have different pitch/spacing. Mind that open source board is slightly thicker, because of another connector. Board dimensions are slightly different too. Main branch also has an incompatible pinout.
