Would a stripped (backlight-removed) LCD pass IR light through? Answered
I'm looking to create a desktop touchscreen interface. I've seen the LCD projectors, but I was thinking that instead of creating a projector, just put a stripped LCD similar to an LCD projector:
underneath an IR display like this:
Beneath it all, I would put an IR converted webcam & a lamp. The goal is to make it as compact as possible under the desk.
This design hinges upon the IR light from the touch screen passing through the stripped LCD.
