Will This Next-Generation Display Technology Change the World?

"I saw the future at CES 2023," writes Geoffrey Morrison, describing "a new, top-secret prototype display technology" that could one day replace LCD and OLED for phones and TVs. "It was impossibly flat, like a vibrantly glowing piece of paper." Meet electroluminescent quantum dots:Until now, quantum dots were always a supporting player in another technology's game. A futuristic booster for older tech, elevating that tech's performance. QDs weren't a character on their own. That is no longer the case. The prototype I saw was completely different. No traditional LEDs and no OLED. Instead of using light to excite quantum dots into emitting light, it uses electricity. Nothing but quantum dots. Electroluminescent, aka direct-view, quantum dots. This is huge. Or at least, has the potential to be huge. Theoretically, this will mean thinner, more energy-efficient displays. It means displays that can be easier, as in cheaper, to manufacture. That could mean even less expensive, more efficient, bigger-screen TVs. The potential in picture quality is at least as good as QD-OLED, if not better. The tech is scalable from tiny, lightweight, high-brightness displays for next-generation VR headsets, to highly efficient phone screens, to high-performance flat-screen TVs. The article predicts the simpler structure means "Essentially, you can print an entire QD display onto a surface without the heat required by other 'printable' tech.... Just about any flat or curved surface could be a screen." This leads to QD screens not just on TVs and phones, but on car windshields, eyeglass lenses, and even bus or subway windows. ("These will initially be pitched by cities as a way to show people important info, but inevitably they'll be used for advertising. That's certainly not a knock against the tech, just how things work in the world....") Nanosys is calling this direct-view, electroluminescent quantum dot tech "nanoLED," and told CNET that "their as-yet-unnamed manufacturing partner is going to be talking more about the technology in a few months... "Even Nanosys admits direct-view quantum dot displays are still several years away from mass production.... But 5-10 years from now we'll almost certainly have options for QD [quantum dot] displays in our phones, probably in our living rooms, and possibly on our windshields and windows."
