A little web search turns up interesting information, e.g. from Wikipedia: "In 1953, Russian scientists showed that triboluminescence caused by peeling a roll of an unidentified Scotch brand tape in a vacuum can produce X-rays. In 2008, American scientists performed an experiment that showed the rays can be strong enough to leave an X-ray image of a finger on photographic paper."
But none of that relates to the fact that it takes only a weak static charge to trigger the LCD, and that is easily generated on the LCD cover glass by simply separating the plastic from the glass, even without adhesive. OTOH, the reason why the film has been taken off at the factory is that some builders did manage to damage the LCD, even pulling the glass off while trying to remove tape that was laid down so well that it was very difficult to see the edge. 73, Ron AC7AC -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Stephen Prior Sent: Tuesday, July 10, 2012 1:02 AM To: Kevin Luxford Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] KX3 Remove plastic film on display? I believe it may well be UV which is produced, certainly visible light is. I agree that the energy is too small for the production of x rays, after all you need to accelerate electrons through 10kV or so to produce x rays. UV radiation exists across a wide energy range compared with visible light.
