We have a set of small LCD units installed in one of our attractions (theme park), and they are suffering what appears to be burn in.
THey are on 18 hours a day, and for about 15 of those hours, they are displaying a static image of a geometric shape, moving cloud and sky imagery the rest of the time.
It was noticed that when the signal to them was blanked, an after image of the geometric shape was still visible. At first it was thought this might me signal leakage, but when the feed was disconnected and a black frame generator hooked up, same result.
I vaguely remember a thread about LCD burn-in on this forum, but search is not turning it up.
Anyone recall, or have advice on how to reverse this? I seem to recall someone suggesting a procedure to correct the problem periodically.
Thanks.
