How did people differentiate between 1 and L, 5 and S, 0 and O?

ex: 1055 & LOSS ( one zero five five & loss)

I'm a fan of HPDL-1414 display modules, which have an integrated character ROM covering the symbols and upper-case part of ASCII: https://www.farnell.com/datasheets/76528.pdf

It does have a few more segments, but all the glyphs it covers are distinguishable.

With more segments than just 11:

This one's missing a period (and question mark/exclamation point), and the opportunity for a hyphen.
