I know I'm a bit late with the response, but I only just started working on my own Pip-Boy a few days ago.
Since I don't have a smartphone that's the right size to fit in one of the Pip-Boy kits, and I didn't want to mess around with EL sheet or anything, I ordered up a super cheap 3.5" digital photo frame off ebay that I'll use for my screen. I'm also using a rectangular magnifying lens to make my screen look like a tiny CRT monitor, and since I didn't want the glare and such already on my screen, I decided to make up my own, completely clean Pip-Boy Screens.
The first one was cobbled together from multiple sources, but the other two are completely from scratch by myself, and feel free to use them!

This way there's one screen for all three settings: Stats, Items and Data.
I purposefully made them so that they’re not specific to any certain game or character name so that they can be used by anyone who might be interested.
Enjoy!
