The fact that quantum dots are already being successfully applied to LCD-LED and OLED screens is encouraging for future QDEL products. QDEL stakeholders claim that the tech could bring efficiencies like lower power consumption and higher brightness than OLED. (Research using a prototype device has recorded quantum dot light-emitting diodes reaching 614,000 nits. Of course, those aren’t the type of results you should expect to see in a real-life consumer product.)
614,000 nits
That’s fucking insane. HDR 1400 displays are at least 1,400 nits. 614,000 nits seems like you’d be staring at the fucking sun.
There’s also hope that QDEL could eventually last longer than OLED, especially since QDEL doesn’t rely on organic materials that can cause burn-in.
Tbh the burn-in issue is the reason why I don’t like OLEDs as computer monitors. I know phones and TVs don’t tend to have major burn-in issues, but the fact that it exists sucks. TVs have a variable-enough image that long-term use isn’t an issue imo, and even the most thrifty person will probably end up replacing their phone every 4~6 yrs. However, I’m used to having computer monitors be long-term things. My last monitor lasted about 10yrs before it died.
As it stands, QDEL displays would become noticeably dimmer more quickly than today’s OLED displays.
Aw, that’s disappointing. At the same time though, if they’re able to get even 10% of the 614,000 nits on commercial units, then they’d have to lose a significant amount of brightness to dim to current display levels.
But optimists believe QDEL display lifetimes could one day be on par with LCD-LEDs and outlast OLEDs.
Yeah, I hope so too.
So the formula for nits to Lumen is below:
N=L/3.426
614,000 = L / 3.426
2,103,564 Lumens
Bruh…
1m² of the sun is 127,000 Lumen. This TV is at most 2 m². It’d certainly be the last thing you ever saw.
Imagine playing CS2 or CoD and getting flashbanged with a screen that bright

I checked the linked paper and sadly this brightness reduced the cell lifetime from over 5000h at 100 Nits to just around 5h.
So unless they find some magic, even better chemistry this TV as bright as the sun won’t happen.

We will continue to wait for the holy grail of micro LED monitors and phones. So far, all of my OLED phones have burnt in around the 5 year mark. Avoiding OLED like the plague for longer lasting devices like Monitors, TVs and (god forbid) car displays.
I would assume a retail ready model would have the capacity for that blinding level of nits, but undervolt to a more reasonable brilliant 2,000 and then add voltage over time to compensate for the dimming over time.
I will say that having a >10,000 nit display could be really cool at 8k, you could produce some really awesome images and stare at the Sun without having to go outside and with less cone damage.
Apparently the Sun at noon is 1.6 billion nits, that would be hilarious in a TV.

I’m posting this from a 7 year old phone with an OLED screen. The screen still looks as good as the day I bought it.
I cannot confirm. The phone I’m writing these very words on is a Samsung Galaxy S10 Plus from 2019 running LineageOS 20, and the AMOLED display is absolutely gorgeous and looks as good as today’s top-tier smartphone screens. But maybe that’s because this is a Samsung flagship, and Samsung is notorious for making kind of the absolute best displays for their flagships.
S10e owner here, still running the stock Android. The display looks factory fresh. Battery is slightly tired but still quite functional, I just wish they’d keep sending updates.

Note 9 owner here, and there’s definitely a little over the years (particularly where the status bar is), but it’s usually impossible to notice. You only pick it up with a blank colour where the difference becomes more apparent.
I was reading this and realized my two monitors are from over 15 years ago…
Cool, so they’ll be available without all the spyware, right? … Right??
No, there will be Spyware in the fucking diodes…
*In every quantum dot
Sometimes when you spend too long staring into the quantum dots, the quantum dots stare back at you.
😂
😳
behold, nanotechnology
Bring on the nanomachines.
Nano-TVs, son.
What is this? A TV for quarks?
Pretty sure these tvs will be the same size as today’s.

We would build this TV and make ants pay for it!
Celebratory shots from AR-15 and red caps get thrown into the sky.
Diode emitting lights?
From the article:
Quantum dots are already moving in the premium display category, particularly through QD-OLED TVs and monitors. The next step could be QDEL, short for “quantum dot electroluminescent,” also known as NanoLED, screens.
No.
Quantum diode emitting lights
Be careful, you’ll need to keep up on vacuuming around the display, or you’ll have tiny diodes scattered all the place.
Also wear safety googles while viewing. Occasionally the diodes shoot our far, especially if there’s a sudden white flash on screen.
Won’t these lose brightness over time as the chemical reactions die out, forcing you to buy a new tv?
That’s that entrepreneurial spirit whenever been looking for! Straight to the top of the corporate ladder with you.
Refills.
HP begins salivating.
Could you imagine a TV needing “printer ink”?
I get the distinct feeling the writer doesn’t understand quantum Dots, and doesn’t understand the technology behind any of the display technologies he attempts to describe.
Come back if you have it on market.
How much do you reckon the first qdel tv cost? 20k?
2000 plus all your personal information, habbits and sex noises you make.
Sounds a lot like Sharp going “please don’t buy OLED panels, we don’t make them!”
My 2017 LG OLED is still going strong, looks great, and when it eventually dies, I’ve seen the 77" model in Costco for just over £2000. For all the chatter about burn in, I’ve never seen any of it, and that’s with heavy gaming use. Not sure I’d use one for desktop PC use, but for everything else, just get OLED.
I just bought two LG OLEDs to replace Roku TVs after the great brickening of Roku TVs earlier this year. I wish I would’ve done it sooner. Even a month later I look at the screen sometimes and am just blown away by how much better it looks than the QLED whatever Roku garbage I had.
Will they be available in computer monitors?
Asking the right questions. I am still waiting for 42" QD OLED monitors to become available
The closest thing I could get is a 32" QuadHD monitor with a VA panel. Best IT purchase I made in a long while.
Quantum!
So if a pixel dies you get to pay more to fix it
You fix a lot of pixels with your current monitor?
I did once with a 17in sceptre. Pixel wssnt dead but stuck dayglo green. Massaged itwith a finger tip and it cleared up. Dead ones would likely require an RMA
I’ve only ever used the jscreen fix for an old monitor that i damaged. Helped after a few hours to soften some of the discoloration. Just wondered.
I don’t know exactly why but for some reason I hate oled. Maybe it’s the flickering thing. Will that be solved with this tech?
What flickering thing?
pwm
Are you confusing them with CRTs? Those are notorious for flickering!
No, oleds have this thing that some people can get headaches from. I have no idea how it works
