12,000 hours/ letterbox bars present for 2 hours, then absent for 3.5 hours so out of 5,5 hours of content 2 hours is letterbox (would mean clear signs of letterbox burn-in after 4,000 - 4,500 hours...two letterbox movies a day for three years)?
Good catch. I thnk someone else had already pointed that out to me but with rtings only putting out updated measurements every month now, my memory fades more than usual between posts.
LT97 or LT95 of 4000-45000 hours @ 175 cd/m2 is correct (we need a measurement on how much brighter the letterbox bars are to decide which).
Think I'm just going to leave my incorrect post as is and let this exchange set the record straight (though if others feel correcting my earlier post would be worth the effort, ease send me a PM and I will do so).
The 2016s are now old news and are what they are.
The 2017s added compensation that hides the first 20-25% of burn-in, so LT97 or [email protected]
/m2 should be 4-5 times longer (16,000-22.500 hours to an equivalent level of letterbox burn-in).
And depending on whether brighter letterbox bars begin to become visible on content at 3% (LT97) or 5% (LT95), 4000-4500 hours on 2016 WOLEDs should translate to 4-8 times than number of hours on a 2017 WOLED (so let's say 15,000-30,000 hours).
The other goid news is that the larger sunpixels of the 2019 WOLEDs should deliver ~200% time-to burn-in on red due to larger red subpixel and this means 8000-9000 hours compared to letterbox burn-in on 2016 WOLED without accounting for compensation and 30,000-60,000 hours compared to letterbox burn-in on 2017 WOLEDs (which we have not seen yet).
