Excellent article. Very comprehensive and insightful.
I understand Samsung is going to produce OLED displays with QDOT.
Often what manufactures avoid talking about is vertical banding on OLEDS. Just read any OLED owners thread here and count how many returns/swaps due to vertical banding. PERHAPS THIS IS ALSO A LIMITATION unless manufacturing improves. Maybe Printing screens is a solution.
Aside from the issues you've already mentioned, another problem with RGB OLED is that the blue sub-pixel decays faster than the other two. This is the main reason LG pursued WRGB and Samsung abandoned its RGB OLED TVs, although the latter is still one of the largest manufacturers of AMOLED screens for mobile devices.I can agree with a significant portion of the argument in this article but it is worth remembering that LG's OLED displays are not 'true' RGB OLEDs in that they only (as I understand it) use a white pixel and a series of colour filters to achieve the picture. Samsung have been working on true RGB OLEDs (that is a red, green and blue sub-pixel) for more than 10 years now but the production process is extremely challenging to commercialise. I would guess that these RGB OLEDs may still be affected by issues such as peak brightness and burn in (although I have seen zero instances on my 2017 E6) but surely the use of three separate sub-pixels would allow OLEDs to achieve a wider colour gamut.
No. Burn in is a non issue. Vertical Banding is number 1 reason for returns. Owners threads.I think complaints about banding have come down in the last couple of years. It was discussed a lot, but now it doesn't strike me as being discussed any more then DSE or uneven backlight on the LCD forums.
The hottest topic currently is Burn in/out. But having been on this forum since the early Plasma days, I suspect that will always be a hot topic. Wether it's prevalent or rare, given it's unlikely there will ever be a no questions asked cover in warranty, people will always question it.
There's been a lot of talk about QD-OLED, but I don't think it's the great saviour that some people believe it to be. I haven't seen a single demo yet, suggesting it's still some way off.I understand Samsung is going to produce OLED displays with QDOT.

I think image retention and burn-in is the big unknown when it comes to OLED. There's no doubt that early models were more susceptible, but new features have been introduced that seem to mitigate the risk. I've owned three OLEDs (B7, C8 and C9) and I haven't any problems with image retention or screen burn so far. However with panels being driven harder and harder, I wonder whether this might become more of an issue as the TVs age.The hottest topic currently is Burn in/out.

Steve, I am curious to know if you only watch streaming content such as Netflix. Is any of the HDR content delivered higher then 1000 nits via streaming. If not, then for people only viewing via streaming [Netflix HDR, Amazon HDR10, iTUNES HDR, Disney+ HDR] there is no benefit for 1000 nits.
Thank you. I understand you know the light nits for UHD’s, but for streaming surely only the Mastering Colourists know this when they created a Digital version.Most of them are capped around 1,000 nits including UHDs.
WB / Sony UHDs usually are 4000-10000 nits.
Disney are the worst of the lot. Most of their releases are low APL.

Totally agree.I have to agree here, I've got a 65C8 bought during the world cup 2018 and no burn in issues on mine. I think for normal mixed viewing at home, its a non issue.
However the biggest issues talked about on the forums are banding/screen uniformity and the flashing macro blocking issues (think it was termed chroma overshoot by Vincent). If LG can produce a band free/uniform and flashing macroblocking free panel then that will be the biggest improvement.
Personally I watch movies with the lights off and I find my 65inch Panel PLENTY bright, in Dolby Vision, the amount of light it blasts out sometimes can be blinding in a dark room environment in certain scenes, so panel brightness for me is also a non issue.

I agree there seems to be improvements, but still very relevant issue and reason people swap out. I cannot compare to DSE issue severity on LCD as not been on those threads.I'm not claiming its prevalent or common, but its the main negative the forum is discussing. Wether that be because someone has suffered from it, or it's holding them back from switching to OLED.
IMO vertical banding is rarely discussed now. It was the most common topic for returns a few years ago. But now it doesnt strike me as being more common then people returning LCD's for DSE or uneven backlight.

I think that Panasonic GZ2000 seems to have surprisingly good screen uniformity. However this was not a selling point, but just happily realised by owners and reviewers.I think like the LCD forums, it becomes a self fulfilling prophecy.
I've avoided using slides to go look for banding. If I dont see it in content, there's no point making it an issue by going and looking for it.
Unfortunately the problems in the early days has led to people recommending using slides. Both on the OLED and LCD forums. And once you start on that road, you will be perpetually swopping out panels. Like any product, you will never get perfection.
It's not trivial driving 25m sub pixels within a relatively small area, in a perfectly uniform manner. Some variation is always going to occur unfortunately. But people seem to think they will get the perfect panel. If I applied that to everything I bought, I'd be returning every product several times
