Nanosys demonstrates the next generation of electroluminescent quantum dot display technology

why does it matter: Manufacturers have been including quantum dots in LED displays for a while now, but they’re working on displays that use them exclusively. The technology could become efficient and cheap enough to find success in LCD and OLED displays as the range of applications for digital displays expands.

At CES 2023, Nanosys held a “hot secret” proof For his latest work on electroluminescent quantum dots – a candidate for the next major display technology. Nanosys wasn’t able to release any photos of its CES presentation, but the capabilities available could be quite extensive.

Considered so efficient because they emit almost all the light they absorb, quantum dots produce light when fed energy and give off different colors depending on their size. Display manufacturers only use red, blue, and green quantum dots, but other colors are possible.

Quantum dots actually make up the “Q” in QLED and the “QD” in QD-OLED screens. Until now, these luminous quantum dots, which receive energy from light, have played only a secondary role to more mature display technologies.

Nanosys’ electrically luminous quantum screens will use only electrically activated quantum dots. It can significantly reduce power consumption and lower manufacturing costs while at least matching the picture quality and brightness of QD-OLED.

The prototype for CES was a 6-inch screen attached to a complex array of wires, but electrically luminous quantum dot displays can fit in a variety of sizes. Manufacturers can use them for large-screen TVs, smartphone screens, virtual reality headsets, and more.

Moreover, the efficiency and low-cost nature of electrically illuminated quantum dots could make them applicable for a variety of surfaces that would not normally include displays. Nanosys believes the technology can greatly advance augmented reality by working with transparent objects.

Nanosys website it contains Artwork that visualizes displays, advertisements, and other information around windows, car windshields, and other glass items. CNET speculates that electroluminescent quantum displays could show drivers important information on their windshields without drawing their eyes away from the road, or create augmented reality experiences over regular glasses.

The company admits that direct-vision quantum dot matrix displays may still be several years away. The format in which it debuts will depend on which display manufacturers will be willing to adopt the technology first: TVs, phones, VR, or whatever.
