QD-OLED (QD-Display) Explained | What's myth, what's fact.

As is often the case with new technologies, the introduction of QD-OLED, A.K.A. QD-Display, has generated some questions, confusion, and misinformation. To get the real story, we spoke with Samsung Display and the quantum dot-experts at Nanosys. Here's how the latest and greatest TV technology actually works, and why everyone is buzzing about it.

Thanks to @BTheInstaller for QD-OLED footage from CES 2022! Check out his channel here:

Hey everyone! Thanks for all the great comments. I appreciate the feedback, both positive and constructive. Keep it coming! Now, what's the one thing you MUST know about the performance of the Sony A95K QD-OLED TV. Anything but price. That info just will not be issued for another couple of months. Let me know as a reply to this post!

[DropkickNation]

Well explained. Haven't been so hyped for a new technology in years.

I still run a 2008 Pioneer Kuro. A true RGB display, the Jacob + Katie Schwarz 4k vids look stunning even at 1080p. QD OLED is the next gen Kuro I have been waiting for.

Thanks Caleb! Having been pretty familiar with the inner workings & tech behind QD-OLED, this is a great explainer video. I also think having just a Blue based OLED layer, there is less chance of uneven aging and the display may not show Red or Green color shift/tint.

[michaelbaldwin]

yes, all well and good, but still waiting for Pioneer to reapper and shock everyone with a 4K Plasma display !

[nikhilaher]

Was waiting for this video since I checked articles on qd- display.Great work

[bd]

Great video mate, thank you. Can't wait for you to review in detail this QD OLED

[GraveUypo]

Just one thing: quantum dots still sap some of the energy from the light for color conversion. about 20%. the thing is that is still less than filters, so it's better.

A TV that runs many hours a day may not be “watched” full time. A TV could include a device that recognizes when there are no eyes on the screen and dim the intensity of the blue led. Commercial breaks could be toned down to give a “break” to the led. It sounds like some sophisticated processing is being used to monitor the degradation of the quantum dots, so a simple tracking of TV watching could be implemented easily.

I'm pretty familiar with the tech behind QD-OLED, but I've been anxiously awaiting this video with your breakdown, Caleb. Thanks so much!

[YungMilOnstage]

This makes a lot of sense! Great explanation 🙌

[jasmadahar]

Great review Caleb. I purchased an LG CX 55” based on your recommendation, and love it. What worries me is that Samsung ignore Dolby Vision which I love and this is a big sticking point with their products. Still, if they were to bite the bullet and use DV, then I’d buy this product without hesitation.

QLED - expensive
OLED - more expensive
QD-OLED... gonna have to sell a kidney AND your firstborn child

I'm eagerly looking forward to Sony's introduction of the A95K QD-OLED TV and Caleb Denison's full review. Even though I'm rarely an early adopter I could seriously consider opting for this new TV technology. My plasma TV is starting to show its age and Sony's A95K flagship model would be a premium upgrade.

[jeromegny]

If we have to expect an extremely expensive Sony a95k line, I can’t wait to know how extreme it will be. They look like terrific tvs and technology.

[Gaurn]

I always thought OLED used an individual oled "unit" for each oled pixel. Whether it's LCD, oled filters or QD, we are just using advanced prisms to get colors. I would really like to see us use just one layer of self emitting pixels; micro led or micro oled.

[richroggio]

that was very informative Caleb, thanks as always for another great video !

[soyanchd]

In my opinion, high end CRT are still the best looking tv ever made. The industy been playing catchup for the past 15 years or so

[bewhee]

So, how are quantum dots better than color filters? If they turn blue light into red and green, don't they lower the brightness also?

[MrOffTrail]

Well explained.
But tbh, I just can’t get excited about TVs anymore, no matter how good they get. This used to be something I was really interested in, so I stopped to think on why this is. I guess I’m just over TV’s. I can’t see a use case for my family anymore. Thinking back on it, we turned on our big TV once in the past 3 or 4 years. Usually, we just use our large-format iPads to watch content. Everybody gets to watch what they want and when, and nobody has to put on their eyeglasses. We can get everything we want as far as shows (but we mostly watch YouTube these days), and I watch sports in apps, and get stats and other data along with the video feed.

I could see this being more exciting for PC monitors perhaps. But I think those days are numbered too. Once they really get VR headset technology locked in, that’ll be the death of large-screen displays. And while you can use them to simulate a large 2D screen, I think it will eventually lead to the death of fixed-view cinema as an art form. I think we’ll end up with theater making a comeback, except you are on the stage with the actors, able to look around at will. And it will revolutionize sports viewing. Imagine being able to choose between a pitcher’s- or umpire’s-eye view of a baseball game in 3D, as if you are right there? And of course it will be a game changer for video games, a revolution that is already in the early stages. I have high hopes for the Pimax 12K that is in the works, but even if that turns out to be underwhelming, somebody is going to figure out the tech soon.

So, I guess I’ve shifted my thinking of video from a big piece of furniture to a personal consumption model, similar to how most people have shifted with audio, moving from large living room-based hi-fi stereo systems to Spotify and Apple Music on headphones, smart speakers, and in the car.
