Sort of related question. I have an old clock with a 3 inch clock face that I want to change to be digital.

Does anyone know where to get a 3 inch round led/lcd display (ideally that can be attached to a Raspberry Pi)? I've looked online and they are either crazy expensive, a round display on a square back, or I have to buy 1000 of them.

I assume I'm just not googling right.
