Electrical – Can you damage an LCD screen with a camera flash, high-powered flashgun/speedlight

lcdlightuv

I'm curious as to what the limitations are in regards to uv radiation on LCD screens when subjecting them to high intensity light sources such as camera flashes (such as a nikon or canon speedlight).

What measures can you take in order to protect against this damage? Dichroic filters? Hot mirrors?

Thanks in advance!

A common camera flash/speedlight should not emit very much UV at all, unless you modify the device. UV will be blocked quite efficiently by most plastic materials (such as the ones used in camera flash "lenses")
