This is a semi-fake experiment which I believe could work, but which I have not fully prototyped into a functional state. It is faked to show a concept.
By treating plain paper with a mix of food-grade ascorbic acid and a solution of UV ink infused with a setting agent, an LCD panel could cheaply be modified with UV LED backlights to become a low cost “photo-copier”.
Useful for quick copies when away from the office or when a printer is too bulky.
Monotone only. Low resolution.
…but not stupid-dangerous, mind you… just dangerous enough to learn a lesson or void a warranty. Trust me. Voiding warranties is the best way to learn how something works. If it has more than one piece, I must take it apart (marbles, you’re safe, for now). It’s an illness that only a tiny screwdriver can cure.
I dedicate this post post to my latest victim, an innocent little LCD projection clock flashlight. I needed to know, so there it is. Gruesome, yes?
Keep on breaking stuff, friends!
