What just happened? Samsung Display has shown off several products at Display Week 2024, including a prototype monitor featuring technology that some say could eventually replace OLED. The Korean giant revealed the world's first 18-inch QD-LED display, which the company calls next-generation self-emissive tech.

We've seen QD-OLED panels appear in several TVs and monitors in recent times, including the Asus PG32UCDM. While QD-LED, aka NanoLED, QDEL, or quantum dot electroluminescent, is also self-emissive, it applies electricity directly to the quantum dots. "This next-generation self-emissive technology features QD RGB pixels emitting light directly through current drive without the need for OLED," the company explained.

Samsung says QD-LED offers a wide color gamut and high color accuracy for a superior viewing experience. As it doesn't have any organic material, QD-LED isn't susceptible to the kind of long-term damage often seen in OLED panels.

Another advantage of QD-LED is that the stable material properties of the panels make their manufacture possible using Inkjet Printing (IJP), something that TCL has used for its OLED TVs. This increases manufacturing efficiency and lowers costs when producing large quantities. QD-LED panels also use environmentally-friendly cadmium-free quantum dots.

The QD-LED set Samsung had on display doesn't have the most impressive spec list. It measures 18.2 inches and comes with a 3200 x 1800 (202 PPI) resolution with just 250 nits of brightness. But the set is a prototype, and the largest one Samsung has revealed to date, having previously shown off 12.3-inch and 14-inch versions.

Shoei Chemical of Japan, the new owner of Nanosys, which creates QD-LED, said it has plans to accelerate the development of the display technology, and it could go into full production by 2025 or 2026 at the earliest. FlatpanelsHD notes that the main challenge facing QD-LED is the lifetime of the blue quantum dot.

Samsung had other products on show during the event, including Ultra-Thin OLED panels, a glasses-free 3D OLED panel, and an OLEDoS display for XR headsets.

It was reported earlier today that TCL subsidiary TCL CSOT had shown off a 4K display with a 1,000Hz refresh rate at Display Week 2024. It was assumed that the first 1,000Hz panel would have a 1080p or 1440p resolution.

1800p is absolutely fine. Please bring 1800p monitors soon. 4K is just still too much for
most games.

Not really, it's just that most people want 4k+raytracing. I play plenty of games on a 6700xt@4k and get 100+FPS.

Granted, I play on a 65" TV, but 4k as a resolution has tons to offer. I don't mind turning the settings down, I just hate fuzzy edges. And if I'm so inclined I can just change the resolution to 3840x1080 and have an ultra wide experience.

Frankly, I'd happily upgrade to a 75"8k display if you could run it at 120hz. They need to put displayport on TVs....

I think all the techs will co-exist
we have TCL RGB printables they were showing off eg laptops RGB 350Nits peak, an 8K screen at 800Nits highlights
The Blu OLED is still a bit short lived in these

We have eLEAP with stackable RGB promising to put out products end of this year

We have LG Display that has made a micro 10000Nit display

Ie LG is still believing it can compete , and has built large factories on this faith.
I think if they can hit 4000NIts and Near Ful lBT2020 that should be enough to sustain them for awhile
We have lots of research into better OLED materials and methods for increased efficiency , less heat. longer life . Especially for Blue

So think still quite away from its best performance

True QD is gaining traction and will be a big player as well

mini-LCD will stick around and give a pretty close performance to emissive tech
I just don't see a future for microLED in mainstream consumer devices anytime soon, unless manufacturing costs can be massively decreased and yields improved (I suppose dead LEDs ?? )

Given that Plasma was king. Panasonic could have released a 4K consumer monster. but decided only a portion of the market wanted such displays vs Bright big cheap LCD. Maybe Panasonic knew OLED was coming as well??

What is "4000NIts"? Do you mean 4000 nits?
 
"Samsung had other products on show during the event, including Ultra-Thin OLED panels"
Love it. This is something I do not like about some oled tvs, they are as thick (at the bottom) as very first lcd tvs.

The problem with Plasma, aside from its power draw, was it was never cost-effective to shrink down much below the 65" form factor. That limited it just to the super-high end.

Kinda a weird compromise, not really my style. Give me eye candy like most people, like you said. 4K medium just really really reminds you you're playing at medium. Where at 1800p you could go to high or very high and probably have a hard time noticing you aren't at 4K but it's still better looking than 1440p and most people could enjoy it where few people can afford to push 4K with eye candy.
 
I wish they stuck to one name. QD-LED is just NanoLED. 2025/26 at the earliest and commercialization doesn't mean mass production.

On my 48 C1, I realized I can have 48" 4K, 40" 1800p, or 32" 1440p, all @120Hz. And they all look great thanks to the true black box around them. Not sure why we need a dedicated 1800p monitor when you can easily get 1800p from any 4K screen. The C1 even has that resolution hard-coded. The 42C2 allows an even sharper (if smaller) 35" 1800p image. Doubt there's a huge market for 1800p too, since it's so close to 4K and 4K is much more versatile as a TV/Movie format.

"the main challenge facing QD-LED is the lifetime of the blue quantum dot."

Maybe I'm missing something here but these statements seem mutually exclusive to me.

They are. The article is in error. Qdel (or QD-LED, if your prefer) uses electroluminescent quantum dots that, although inorganic, currently suffers worse burn-in issues than OLED. But - as I've posted in other threads here - there are strong reasons to believe the tech will rapidly see longevity improvements that will largely obviate the issue.

Display wise, it still holds up. My parents are still using a Panasonic VT65 we got them at a clearance sale once Panasonic killed their plasma brand.

Yeah still have a lovely SDR picture. In NZ, when Panasonic said they would end it, prices dropped a bit , not a fire sale, but good discount, then later shot back up real high over MRP . When shops/consumers last chance to get best of best
Given the massive size and weight, prices were quite reasonable, given flagship price on a Sony A95L , LG G4, Samsung S95D 65"

Saying that in NZ colour TVs were really expensive brand new in the 1970s in today's money. Probably had a lot of import duty on them as well. many families brought second hand ones

I snagged that VT65 for just over $1k. That was an absolute steal.

27in 1800p is nearly the same ppi as 32in 4K.
1800p is 5.76MP. 4K is 8.29MP. That is a substantial increase in pixels and hardware requirement for the same exact pixel density. Look at the market for 1440p, that's not a TV resolution. I also don't want a very large screen on my desk. 27-30in. 4K is a hype that needs a reality check.

Fair enough. 27-30" 1800p would be a nice boost in screen real estate from 1440p, and likely without the cost of 4K.
