Expending effort to understand/analyze an outlier is a waste of time, but if you believe you understand the facts surrounding that use case, I'd be happy to try.
In general, my sense is the following:
-First reports of burn-in on 2016 WOLEDs emerged in April 2016 and accelerated by summer, about a year after introduction.
-Those cases of burn-in were primarily examples of frequent CNN/MSNBC watchers that accumulated hundreds of hoyrs of cumulative static logo content watching over the course of a year.
-The Rtings.com 2016 burn-in test proved that noticable burn-in of red can occur after only 560 hours at 175cd/m2, so 2 hours of CNN a day for a full year, and there you go: http://i.rtings.com/images/burn-in-t...-red-large.jpg
-Someone analyzed the rtings images and confirmed that burn-in at the 5% level become noticable (meaning a burned-in logo which has 95% brightness on a field at 100% brightness).
-For 2017, LG reserved an undetermined amount of brightnessvheadroom to enable burn-in compensation technology. That headroom was obviously at least 5% and may be as much as 15% or 20% (TBD
-At 200 cd/m2, the burn-in compensation technology has largely succeeded to mask burn-in for 3360 hours (week 24): http://i.rtings.com/images/reviews/t...-red-large.jpg
-Those owners who are viewing ~600 hours of CNN or MSNBC per year at 200 cd/m2 or less and not going to develope visible burn-in for 5+ years and so we have had no reports from any of them on 2017 WOLEDs a year after introduction.
-Even those owners who are viewing ~600 hours of CNN or MSNBC per year at 375 cd/m2 (OLED Light = 100) are not going to develope visible burn-in for 4+ years (2500 hours - week 18): http://i.rtings.com/images/reviews/t...-red-large.jpg
-The net-net out of all of this is that we have not yet seen any
,reports of burn-in on 2017 WOLEDs one full year after introduction and we are unlikely to see any such reports from any other than cable news addicts warching over 1000 hours of CNN or MSNBC per year until 2020...
As I said before, bravo, LG
