![]() ![]() ![]() They're also extraordinarily efficient, almost perfectly emitting the same amount of energy absorbed.įor the last few years, quantum dots have been used by TV manufacturers to boost the brightness and color of LCD TVs. There are more possibilities, but for display tech, RGB is all you need. Or to put it another way, some dots emit red light, others green, and others still, blue. Different size quantum dots emit different wavelengths. Quantum dots are tiny particles that when supplied with energy emit specific wavelengths of light. The main difference is being able to add the QDs to the diffuser plate instead of it having its own film layer. Two of the current methods of adding quantum dots to LED LCD displays. In the meantime, here's what I can tell you. Its reps told me its as-yet-unnamed manufacturing partner is going to be talking more about the technology in a few months, however, so hopefully we'll learn more soon. It's so cutting-edge, Nanosys said I could only show a blurred image and couldn't take any video. It felt like I was staring at something from the future, because basically I was. A gallery of colorful nature images cycled through on screen, the de facto standard content for preproduction display demos. It was impossibly flat, like a vibrantly glowing piece of paper. A maze of wires connected it to multitiered circuit boards. And there on one table, farthest from the door, was the 6-inch prototype I had come to see. Inside the Nanosys suite at the Westgate hotel, a short walk from the convention center, tables against the walls showed different TVs and monitors featuring quantum dots. The prototype I saw at CES wasn't simple, however. A simpler structure makes these displays theoretically so easy to produce, they could usher in a sci-fi world of inexpensive screens on everything from eyeglasses to windscreens and windows. They have the potential of improved picture quality, energy savings and manufacturing efficiency. They could possibly replace LCD and OLED for phones and TVs. These are even more advanced than the quantum dots found in the TVs of today. What could be so interesting that I'd drive an eight-hour round trip to see it? Electroluminescent quantum dots. Not just any next-gen display, but one I've been writing about for years and which has the potential to dethrone OLED as the king of displays. However, a few weeks before the show, Nanosys, a company whose quantum dot technology is in millions of TVs, offered to show me a top-secret prototype of a next-generation display. And if I didn't have to attend, I'd rather avoid it. I saw the future at CES 2023, and I wasn't even planning to go. ![]()
