Bad news. And this is really bad news. Our monitor screen is not UV transparent. All this time we assumed it was but we thought wrong. It's not SO bad though because there are monitors out there that have uv transparent glass and polarizers in them according to my research.That is indeed an annoying setback, but at least your motor, controller, framework, and other components are still viable. Have you investigated whether the LCD panel has some sort of coating that can be peeled off? I know that that is the case with some panels.
