I need advice from electronics enthusiasts
Each segment lights up individually and I've had a tough time thinking of a way to create the display in a compact form. I quickly had to rule out using LEDs because trying to fit sixty LEDs into a tight ring like that would be impossible in a small watch and I don't especially want a pocket watch the size of a dinner plate—even as a prototype. After searching a bit more I learned about LEC panels and I think that this might be what I'm looking for but I need to know if it's possible to do what I hope with it.
The EL panel I linked to is a light-emitting capacitor. If I understand correctly that means that you need to wire the back side and the front side of the panel for each segment that you want to light up as well as breaking the circuit between all individual segments so that only one lights up at a time. Since there are 132 segments that's quite the task but it's still better than using separate LEDs. My plan is to take an EL panel and cut this pattern into it which should break the large panel into smaller independent sections that can be turned on and off separately while still remaining connected. I may edit that pattern to be a bit easier to wire up. After I get that all wired and running I would attach a black cover made from this template to block the excess EL Panel from being visible.
What I need to know is if it is possible to do this and any tips or advice any of you may have. I'm a complete novice when it comes to actually building this sort of thing so I need to know whether it's worth spending my money on the parts for this or if it would be better to try a different approach. Thank you for taking the time to read this. I hope you all have a fantastic day.
