Here is Top-Secret Prototype Display. CES 2023 is where I glimpsed the future, despite not even having plans to go. Even if I didn’t have to go, I didn’t want to because the show is a grind. Nevertheless, just a few weeks prior to CES this year, Nanosys, a company whose quantum dot technology is used in millions of TVs, offered to let me see a top-secret prototype of a new sort of display. Not just any next-generation display, but one that I’ve been writing about for years and that could unseat OLED as the display king. I did a motel booking right away.
Electroluminescent Quantum Dots
Why would I go eight hours round trip to see something that I find so fascinating? quantum dots that emit light electrically. These are even more sophisticated than the quantum dots used in modern TVs. They might take the place of LCD and OLED in phones and televisions. They may result in better picture quality, energy savings, and production efficiency. These displays are theoretically so simple to manufacture that they might usher in a futuristic world of cheap screens on everything from eyeglasses to windscreens and windows.
Top-Secret Prototype Display
But the CES prototype I saw wasn’t straightforward. A little distance from the conference centre, in the Westgate hotel’s Nanosys suite, tables against the walls displayed various quantum dot-based TVs and displays. The 6-inch prototype I had come to view was sitting on one table, furthest from the door. It was connected to multitiered circuit boards by a labyrinth of wires. It appeared to be a vibrantly shining piece of paper and was impossibly flat. The de facto standard content for preproduction display demos cycled through a library of vibrant nature photos on the screen.
I was, in fact, looking at something that felt like it belonged in the future. Nanosys told I could only present a blurred image and couldn’t capture any videos because it is so cutting-edge. But maybe we’ll learn more soon; according to its representatives, its as-yet-unnamed manufacturing partner will be discussing the technology in more detail in a few months. Here’s what I can tell you in the meanwhile.
The QD Past And Present
Let me go back a bit. When given energy, microscopic particles called quantum dots release particular light wavelengths. Quantum dots of various sizes emit light at various wavelengths. In other words, some dots emit red light, some green light, and yet others blue light. Although there are other options, RGB is all you really need for display technology. Additionally, they are incredibly effective, almost exactly expelling the same amount of energy as they absorb.
Quantum dots have been used by TV manufacturers in recent years to improve the colour and brightness of LCD TVs. “Quantum” is what the “Q” in QLED TV stands for. Quantum dots, which were previously only seen in high-end TVs, are now present in mid- and lower-end TVs from manufacturers including Samsung, TCL, Hisense, LG, and Vizio. They facilitate better colour, increased HDR brightness, and other things.
Samsung recently coupled OLED’s outstanding contrast ratios with quantum dots. Some of the highest image quality QD-OLED TVs ever have been produced by them (and partner Sony).
Quantum dots have traditionally played a supporting role in other technologies’ games. a futuristic performance enhancer for outdated technology. QDs weren’t a stand-alone character. That’s not the situation anymore.
Direct View Quantum Dots
The quantum dots now employed in display technology are “photoluminescent.” They radiate light after absorbing it. This often meant LEDs generating blue light in the case of LED LCD TVs. In addition to making red and green quantum dots emit their own coloured light, this blue light was also employed to create the blue light you see on television. Thus, the blue light from the LEDs and the red and green light from the quantum dots would combine to form the image you would see on the screen. Although there are many other ways to carry out this process, that is the fundamental principle.
I saw a completely different prototype. neither conventional LEDs nor OLEDs exist. It makes use of electricity to activate quantum dots rather than light to make them emit light. Only quantum dots are used. direct-view quantum dots, also known as EL dots. It’s a big deal.
