Samsung Display has stopped manufacturing LCD panels last year and has sold its related US patents to a Chinese company (https://www.thelec.net/news/articleView.html?idxno=4183). While Samsung Electronics (separate company) still sells LCD TVs and monitors, those use Chinese panels now. Due to the general trend in LCD panel pricing, the manufacturing in Korea probably wasn’t competitive anymore.
Yep - Samsung sources all it's LED panels from China now (TCL I believe), but naturally tries to keep this quiet. Samsung Display now manufacture QD-OLED panels for medium to large panels and RGB OLED panels for small-medium panels.
 
Why even report this? It‘s so for out, a lot can and will change with their planning based on things beyond their control.

But he, then you can write an article saying the “cancelled it”
I'm guessing this is priming investor expectations for what to look forward to in case the $3k ski goggles don't fly off the shelves.
 
Would this be higher than 8K like the 32” display is 6K, something like 10K? I’m assuming it’s done like that to get a full 4K preview of video content and the rest is used for software UI and to fit Apple’s ppi retina requirements.
It seems that for monitors, retina is defined as being >200 ppi. For 32" this is 6k and for 42" this is 8k.
 
A 42“ retina display would be 8K …

Or in layman’s terms: 🤤🤤🤤🤤🤤🤤🤤🤤

That's bigger than my TV! I have a 40". Obviously, I don't really care about tv or movies or I would have a larger screen...but, for movies and tv and I can see having something that large. For a computer, though? Why?

I have two 24" monitors at work and that's about the limit of the screen real-estate that I want. I tried three, but went back to two.
 
According to the article, this is about QD-LED vs WOLED:

LG Display explained that the reason its panels fared better is thanks to its use of white subpixels. The deeper meaning of this explanation was lost on no one. Samsung has made LG’s white subpixel a prime target in its promotion of QD-OLED panels, claiming that the white subpixel reduces color accuracy by washing out the adjacent subpixels.

For its part, LG is now striking back by saying that without the brightness boost afforded by those white subpixels, Samsung is pushing its own OLED pixels too hard and that burn-in is the consequence of doing so.


In addition, QD-OLED has the problem of more color fringing. (https://www.thefpsreview.com/2022/0...-alienware-aw3423dw-samsung-qd-oled-monitors/)

It is yes. But QD-OLED is newer than WOLED and these two companies are the only game in town currently. JOLED just went bust and it's not looking good for the smaller upstarts right now.

But you can view the full article here where they found both QD-OLED and WOLED to be burning in more so than previous panels.


In my own testing with the PG42UQ, I actually had image persistence by the end of the very first day I owned it. And that used WOLED from LG. The pixel cleaning removed it, meaning it was not permanent damage but I literally have never had that happen on any of my IPS LCD's so having it happen literally within the first 8 hours of ownership was my first wake-up call that OLED (and specifically in my case LG WOLED) was not appropriate for my desktop use case, I think for gamers who don't do any kind of office work that creates lots of static imagery it's usable.

One last thing I wanted to mention, both the WOLED and QD-OLED panels available right now for PC monitor use are all low-density. 105 PPI. Apple would much more likely ship displays around 168-220 PPI where the text fringing issue will not be a problem. I noticed a lot of fringing on the monitor I just mentioned which had the white sub-pixel and although that was a 4K panel it had a low pixel density due to its 42" panel size. 4K/5K at 27" I don't think the fringing would be noticeable.
 
OLED displays are great but prone to burn-in, which is especially an issue when used with desktop interfaces which tend to display static elements for extended time.

Hopefully Apple will have the issue sorted out, but it's a concern.
Oh, they'll sort it out, but it will delay the monitor until 2029.
 
I don't know if I could fit three 42 inch monitors on my desks. With my current workflow, I need three screens on my Studio, three screens on my Linux box and an additional two screens on my M1 Mini that I use for testing. With my next project, my home office will probably be expanding into my library. Early this morning I was measuring for a new desk, making sure it would not block bookshelves. I strongly suspect that much furniture moving is in my near future.
 
32" imac i bet a lot of people will buy it
SoCs and monitors need to stay separated. They simply don’t get upgraded on the same timeline for various reasons. If you tie them together the cost of an upgrade doubles whether you want it to or not. That’s why I don’t see a 32” iMac Pro anytime soon. A cheaper Pro Display XDR would be preferable. Ideally without the $600 tax for throwing in an M2 and webcam.

I wish I lived in your area and had that much square footage in my apartment! I would have to sell my electronics, clothes, and probably body too, to afford that kind of rent here.

Yes, I’m waiting for 27" 4K OLED myself, as that would match the font size I prefer at two-pixel stems. I’d like to try OLED for desktop use. Based on my iPhone and Samsung tablet experience, I think it could work at the lower brightness levels I use. Temporary image retention is expected and wouldn’t be a deal-breaker for me.

It’s a pity that JOLED went bust.
 
I suspect the best solution to image retention is having the system take a screen sample every few minutes, then average the images together and display a super bright negative of that image late at night. If anyone happened to be walking by when that happened, "Why is your computer displaying a negative image of porn and your bank account numbers?" You could probably get a similar result by having your computer display a white screen at full brightness, taking a photo of that screen, then creating a negative map from that to burn in everything that was not burned in.
 
42” would be awesome… not so interested in OLED on the desktop though. If it’s that far out, why not target micro-led?

In the meantime, I love the Pro Display XDR. They should drop the price $1k to make it a little more accessible…

All you’re doing then is reducing the lifespan and overall brightness of the monitor.
 


Apple will transition almost all of its iPad, MacBook, and external display models to OLED displays by 2027, according to technology research firm Omdia.

Omdia's latest IT OLED display forecasts, seen by OLEDInfo, claim that worldwide OLED shipments will rise rapidly from around 9.7 million units in 2022 to over 70 million in 2028. Most of this growth will be driven by laptops, but the number of OLED tablets will also increase sharply during this period.

The main contributor to this expected increase is said to be Apple's expanded use of OLED displays across its devices. In line with other rumors, Omdia believe that Apple will begin using OLED panels for the iPad starting with new iPad Pro models next year, followed by an OLED MacBook Pro in 2026. Apple will almost entirely phase out LCD and mini-LED displays on mobile devices by 2026.

In 2027, Apple will apparently begin using QD-OLED or WOLED panels for 32-inch and 42-inch displays, likely for future iMac or external display models. The Pro Display XDR is Apple's only existing product with a 32-inch display and there is no currently 42-inch device.

Nice!
So at least 10.000€ for the 42“, I assume?

The only practical way to remove image retention is wear leveling. You can't bring the worn pixels back. The other method is to artificially dim the non worn pixels and over drive the ones that are. That simply dims the screen and burns out the effected elements faster.

Edited to say:
dimming the pixels that are not burned and overdriving the ones that are would also greatly reduce your contrast.

OLEDs already implement compensation cycles which are designed to detect pixel degradation and attempt to compensate it. These cycles are performed when the display goes in standby after a set amount of hours of activity.

These cycles are not a silver bullet though: they can only compensate degradation up to a point before permanent damage becomes visible.
