when you remove power from those, does the display go blank?

  If I’m not mistaken yes the power does go. I have a smartwatch with a 30day+ battery life (Amazfit Bip) which also uses I believe the same type of display. It’s ~somewhat similar to a calculator 8 segment display in operation - low power, low resolution/pixel density, can be inverted etc. Or maybe old gameboys perhaps?
