This is the original screen I intended to use, powered by 12V DC and having a discrete controller board it seemed ideal.

Unfortunately I could get this screen to light up and nothing else.

I'll continue to troubleshoot it and will return to this setup if I can.

You can see the first iteration of nylon "welding" which is actually quite strong.

Additionally this is 1mm vent holes, which seemed too small so I bumped them up to 2mm for the next iteration.

The PowMr screen didn't fit AT ALL and I had to hack at the hole to make it fit.
