I found this YouTube video of a guy ripping apart broken lcd panels to repurpose the innards into lighting panels.
And I immediately though about using this design for hanging a Backglass, or possibly even a movie poster. I’d assume once you get the filter layers removed from the lcd panel, that you could cut them to size and just build a new frame to match.
The key to this design is the light diffuser layers in the panel. Next time I see a large broken tv on the side of the road I might pick it up and give this a try.
