When you say “low res” - there are two types of technology:
Active matrix LCD displays (which have a definitive pixel count ranging from everything from your super high res retina iPhone all the way back to the monochrome display on your first generation gameboy)
Segmented LCD displays (which I think is what you are referring to) have no resolution. They are defined segments that are either on or off against a solid color background. This is your Casio wrist watch, Treadmill display, etc. There are very few limitations with these, but obviously as segments increase, so does the cost. Additionally you do need to take into account the electrical traces that will power each segment - usually this requires some type of gaps or paths between segments.
But in terms of inspiration, you’ll find more in 5 minutes on Google image search or Pinterest then anyone will have time to post fresh here.
