A few people have seen this behaviour on the PLED displays, so I've been
looking into it.
The light emitting polymers used in the PLED display behave differently to
liquid crystal displays.
It seems that their brightness reduces over time.
The makers quote a brightness half-life of "more than 10,000 hours", which
would mean leaving a pixel turned on 24/7 for over a year would reduce its
brightness by 50%.
Do you leave your P3 switched on all the time ?
It could be that a screen-saver is called for.
Anyone else seeing noticeable degradation of the display ?
