, What's the most promising OLED tech in this regard?
We know that LG made significant improvements to burn-in resistance and conpensation in the 2017 model year and the continueing Rtibgs.com 2017 burn-in test prove how significant those improvements are - burn in went from something that could be caused by hundreds of cumulative hours of bright, fully-saturated static elements to something that required thousands of cumulative hours of bright, fully-saturated static elements (4200 hours of CNN @ 200 cd/m2; 2500 hours of CNN @ 380 cd/m2).
There are a few reasons the 2018s coukd further improve upon the 2017s and the 2019s may further improve upon that, but we don't yet have any 3rd-party test results to quantify any improvements.
Starting with the 2017s, now that LG has entered the era of estimating burn-in ad reserving brightness headroom to compensate for it, it becomes much more difficult to guess what improvemets may have been made without test results.
Top emission will result in a significany reduction in mA/cm2 for the same brightness and hence a significant improvement in burn-in resistance.
I'd say that the 2017 technologies moved us from a 'hundreds of hours' of static/non-random content problem to a 'thousands of hours' of static/non-random content problem but we're not likely to get close to a 'ten thousand hours' of static/non-random content -level issue before LG lanches top-emission.
So the good news is that if you estimate and realize that you may have a few hbdred hours of non-random static elemts displayed on your WOLED, you no lobger need to be terribly concerned about burn-in, but the bad news is if you are likely to have non-random/static elements displayed for thousands of hours during the expected lifetime of your TV, you're probably better off sticking to LED/LCD...
And all of these estimates are for moderate peak viewing brightness of under 200cd/m2 (SDR). If you are alumens junkie and watch at OLED Light 100 and oeak brightness levels close to twice that level, your 'time-to-burn-in' as summarized above will be reduced by half...
The case of the mute button being burned-in despite very low hours of display is very, very strange. Makes me wonder about something that happened during LGs testing before shipping the TV (like the burned-in 'rectangles' that Rtings.com exposed).
