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.

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.
