A pretty reasonable way to prototype fixed segment LCD displays. I'm kind of on the fence about the on/off backgrounding stuff.

The backgrounds are achieved by having two overlapping elements in different colors. If you use the font standalone, you wouldn't get the two-tone appearance.

Ah good to know.

I'm not convinced that, in the 14 segment font, we should just give up and accept that lower case "a" and "m" should just be the same as their upper case counterparts:

We can represent a "double storey" a like this:

   ___
      |
   ___|
  |   |
  |___|
It's also unclear why we couldn't have a 14 seg lower case m like this:

   _ _
  | | |
  | | |
Maybe for each character, have a link to a documented rationale.

EDIT: Oh, look at the example font sheet featured in Wikipedia's Fourteen-segment-display page: it has these letters exactly as I say:

If you’re at all interested in segmented displays Posy’s YouTube video about them is pure gold: https://youtu.be/RTB5XhjbgZA

This rare 22-segment display is the most interesting I've seen so far. It can display the full 7-bit ASCII range including special characters: https://www.youtube.com/watch?v=D2cyZoCat_U

All the letters in DSEG14 are in upper-case, regardless if a lower case variant is possible. It appears to be a stylistic choice.

Only DSEG7 has lower case letters, and that's probably only to distinguish them from other characters or numbers (e.g. h/X, i/1, or o/0).
