That said, AFAICT microleds are the only technology that really lets you tile them. So you can build a 4K UHD display that is basically a bit smaller shorter than 8 feet (2.5 meters). But at 31 PPI it isn't great up up close. (not bad obviously but not stunning). Once it crosses 72 PPI that is when the world gets really interesting. For me.
In the specs for The Wall microLED display, they mention a pixel pitch of 0.84mm. A quick conversion (1 inch = 25.4mm) tells me that's roughly 30 pixels per inch - oh, right, that's what you meant by 31 PPI, you already calculated it. :)
Still, it's an attractive product, and I can imagine many use cases. Looks like the price range is $17~22K, for 9.6m x 5.4m dimension.
So... if your average viewer will be farther away from this wall than a desktop user, the DPI can go down and still be attractive.

No matter what particular bit of new display tech they're advertising it's always the following too:

I'm on a conventional led, how can I actually see what the wall version is like?
On the other side doesn't Sony, Barco, Christie and a few other signage companies have something similar to it?
They're made to be quickly set up and torn down, hanging from cables or lighting supports.
Perhaps this version by Samsung is easier to configure in odd shapes? I've seen a music show (Jon Anderson) where he had multiple vertical panels with large gaps in-between (several feet) and the panels all showed parts of the same video as though it was one display, with gaps in the image where the physical gaps were. So there is some configurability in existing modular LED walls too.
If you search on eBay you'll find the panels listed by the pixel spacing, P2, P3, P4, P6 where the number is the number of millimeters spacing.
You can buy a 10ft x 5ft, P3, 18 panel system for around $10,000 complete except for the laptop to run it. Various show control software has the ability to map video or graphics to pixels on the panels (VDMX, GrandVJ, MadMapper, QLab, etc.)
I dunno about Sony, but the Sharp and Philips models I could find had thin bezels too. When you tile displays, you have two bezels touching, so the black line is at least twice as wide.
Zero bezel on 4 sides also seems to be noteworthy, because it removes some ways in which one could 'cheat'. For example the new iPhone. From what I understand the bezel on the sides and top could be zero instead of just really really narrow, but the bottom edge has the display electronics attached. To keep from having a big bezel at the bottom of the phone they folded the screen over, so the electronics sit behind the display instead of below. I'm not sure that allows true edge-to-edge display, so Samsung would have had to do some other trick instead of feeding signal in from the edges.
A wall display that can be tiled on three edges still allows for quite a big bigger displays (especially in situations where long linear ones are good, like balconies or the barriers in MLS fields), but not quite like this one.
IIRC Sony has Crystal led (which is just a brand for their micro led), and other companies have a sub 1mm pitch led walls which should be pretty similar.
For a more "classical" solution there are LCD's with hairline bezels like Barco Unisee's, but again even those are far from consumer prices.
Samsung for long been trying to make LEDs in-situ on backplane, and they had samples in labs at least 5 years ago.
These individual modules measure 31.75 x 17.86 inches, but have an individual resolution of 960 x 540 pixels. In order to enjoy the same 3840 x 2160 resolution you'll get on a standard 4K TV, you'll need to buy 16 of these panels, to set up in a 4 x 4 configuration that measures 146 inches diagonally.
Making smaller displays this way will be a challenge as the pixels will have to get closer together.
You can see a little line on certain images (for example at 0:20) but maybe it's caused by the sliding mechanism, because there is no line on the left side assuming they are put together from two square panels same as the sliding one.

Guess the next ad campaign will read like this:

2x superior color purity is no mean feat. Such advanced technology can transcend beyond the boundaries set by your paltry screen.

What's your problem?
It's not that you can't make a post discussing astroturfing on HN or that you can't point out astroturfing to someone that can actually do something about it it's that you aren't supposed to just respond to an article that you think it's astroturfing as that helps nobody even if it is or isn't actually astroturfing.
IMHO OLED displays are analogous to Plasma displays back in the day: A new tech that enabled many new form factors (Thinner TVs) but had many key drawbacks like power consumption and burn-in. The same is the case with OLED, which enables new form factors like foldable displays, but brings its own issues.
I've been actively avoiding OLED displays for all my purchases due to its major current drawback: Burn-in. As beautiful as OLED displays may be with color and contrast, I have seen plenty of TV displays and phones with a permanently burned-in image of something that remained static for too long such as network logos, and status bars. My previous employer used beautiful 80" Samsung displays for their conference rooms, all of which were ruined in little over a year.
This matters a lot to me because I use my TV for gaming, which involves static menus that will burn OLED displays if you're not careful.
This is not something current LED displays are prone to, and I'm hoping micro LED displays work the same way.
I will disappoint you. LED displays have burn ins too! And with pixel sizes approaching that of OLED, burn ins will start sooner, and be more visible.
Samsung will not go for microled for consumer market until it gets "led on the backplane" going. That eliminates the transfer process, and most of cost associated with it.
The unsolved issue is current transfer. If you grow LED in-situ, you have to somehow put power supply there too, and preferably do it in the same manufacturing process.
If you have to transfer LEDs mechanically, it makes little cost difference to put LED driver ICs there mechanically too.
Another artifact OLED displays have is their PenTile subpixel arrangement to compensate for the red, blue, and green organic compounds degrading at different rates. Hopefully micro LED brings us OLED quality with LCD reliability.
Those LED displays you can get in retail are nowhere close in die size to what microled is. Those conventional 1080P led displays with <1mm pitch already demonstrate very visible burnins. There is one in a hotel nearby that is only 4 moths old, and I can already distinguish an imprint from the brand logo, they seem to have unknowingly ran it on maximum brightness though.
Do you mean the LCD displays with LED backlights; that's what I've seen in retail, marketed as "LED TV"? Are you seeing burnin of the LEDs, or image retention on the LCD? LED burn in might look more like noticeably different white levels across the different local dimming areas, especially if it gets worse over time related to static brightness differences in the displayed image.
