Does e-paper fit your description? (nice because it only takes power to change, not display)
There are LED light arrays.
I don't think this is what you want, but it came to mind: https://en.wikipedia.org/wiki/Refreshable_braille_display
Yes, ePaper, while still being a scream looks to be relatively cost-effective and certain programmable
Check out the Mui wood display (https://mui.jp/#en). It seems as though it would fit a kitchen display quite nicely. When not in use it doesn't even resemble a display of any kind, it is a little pricey though.
This looks really cool, definitely fits my definition of a programmable non-screen display. Thanks.
What about a projector?
Since screens are already so abundant, I'd like to use something which does not have a screen.
After much thought the only thing I could come up with is a Split Flap Board. There is a company making them but it's cost prohibitive (smallest ones are over 5K).
What are some programmable displays which are not screens?
