Current-limiting resistor for the Optrex green LCD

Which value do you use? The datasheet available at Mouser is not very complete.

Its low, I stuck a 500R pot on mine and it was a couple turns above short to be acceptable

I’ve put a 100R resistor on mine. It’s working nicely !

I used 100R and it’s plenty bright.

100R as it was recommended. works fine.
