    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 loose 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.

      phones definetly have issues with burnin still. my last phone had it as well as some image degradation despite constant promising its all good now. at this point ill just stick with lcds until we have better tech.

        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.

        I am worried about burn-in on computer screens, but at the same time I am just wondering about how others use their phones, my last 4 phones had OLED and I have never had any burn in occur. I bought a used Galaxy S4 mini at some point and when I got it had slight burn-in of some icons, but it didn’t get any worse in the two years I was using it. Am I maybe just too old because I use a computer while young people use their phones for 10 hours a day?

          As a young person that uses their phone extensively, daily driving both a Samsung Galaxy S10 Plus from 2019 and a Samsung Galaxy S24 Ultra from 2024 for about 6 to 7 hours every day, I can tell you that at least for flagships, AMOLED display burn-in is a non-issue, it arguably does not exist.

      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 star 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.

      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.

      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.
