RE: Thus has Vision Pro written all over it!14 Jan 2024 10:49
I'm not a PHD chemist, but a read of articles out there will tell you the fundamental issue.
Red and green electroluminescent QD lifespan is 20000 and 30000 hours respectively. Blue is 200 hours. That's really the issue, as you can't really create a true QDEL display with one-third of your pixels missing or using another technology.
So the requirement for true QDEL is a blue emitter with a minimum hundred fold improvement in lifespan. That's quite an ask, and it's been an issue for OLED display too, which is why true RGB OLED never caught on in large display format. My guess is it'll probably require some radical change in the materials used.
The tech which is more likely to succeed and become the big hit within the next decade or so is microled, possibly with red and green QD's correcting blue microled pixels in some applications, although the school is out whether native RGB microled (e.g. Porotech, Plessey etc.) will trump that technology.
