I'm working on something where i need to display 20 independent 2-digit numbers that are located in different places. In current prototype there are 20 extruded in plastic numbers with led backlight. The drawback for my application is that I cannot change the order of numbers. I can live with that, but dynamic numbers would be cool and would enable some other useful features.
Long story short, while I was going to sleep last night I thought "woah, I can probably use some displays". Well, after some thinking it became obvious that 7-segment displays would require enormous amount of pins or expensive driver ICs. Also, my application is in very limited space. So, could someone help me out and give an advice how to implement this? Or prove that it's too stupid. I know that it sounds like an absurd idea, I just want to be sure. Thanks.
