RLCD, so the screen itself is transparent? If it were rendering an image, and a spotlight shown through it, would it project the image effectively?

I've had some silly little art projects that I'd love to try this screen for, if you have any spares/prototypes or anything you wouldn't mind selling or sharing!




What you're describing exists already: https://en.wikipedia.org/wiki/Projection_panel. You can find plenty on eBay.

No, because shining a spotlight through it wouldn't result in an in-focus image. Draw something on some transparent plastic wrap and shine a light through it and observe what occurs.
