Saphlux and Leyard Plan to Launch QLED Direct View Products in Q4
On October 4, 2023, the Royal Swedish Academy of Sciences decided to award the Nobel Prize in Chemistry 2023 to Moungi G. Bawendi, a professor at the Massachusetts Institute of Technology (MIT), Louis E. Brus, a professor at Columbia University, and Alexei I. Ekimov, a scientist at Nanocrystals Technology Inc., in recognition of their pioneering contributions to the discovery and synthesis of quantum dots(QDs).

In April 2023, Leyard and Saphlux jointly launched the world's first 162’’ 4K direct-emitting QLED display, marking the successful integration of quantum dots into Micro-LED direct-emitting displays exceeding 100 inches in size for the first time.
In the following six months, the R&D teams of Leyard and Saphlux, after product refinements, successfully developed the QLED direct view product covering various sizes ranging from P0.9 to P1.2. These products are set to be officially launched in Q4 of 2023. Introducing these products will propel the industry into the era of direct-emitting QLED displays, ushering Nobel Prize-winning technologies into the next-generation displays.

Direct-emitting QLED displays offer several advantages:
Wider Viewing Angle
The QD red chip achieves an expansive viewing angle of up to 150°, ensuring consistency across the R, G, and B light sources and making it ideal for applications such as XR shooting backgrounds, stadiums, and venues.
Superior Color Performance
QDs in QLED displays deliver outstanding color stability and gamut, remaining unaffected even under temperature and current fluctuations. The wavelength remains consistent, meeting display requirements under varying brightness levels in different environments. It also ensures color uniformity across different display areas of the entire screen.
Safe and Environmentally Friendly
The manufacturing process of conventional red chips relies on gallium arsenide and phosphine as essential growth materials, both of which are highly toxic and pose hazards to environmental safety and human health. Inorganic arsenic has been classified by the World Health Organization as a highly toxic and carcinogenic substance. In contrast, the use of a gallium arsenide system is avoided throughout the entire production, usage, and recycling processes of QD chips, reducing the impact of toxic materials on air, soil, and water quality.
Research on semiconductor QDs began as early as 1980 and has attracted numerous scholars over the past 40 years. One of the most outstanding optical properties of QDs is their ability to adjust their emission spectrum by changing their sizes, covering the entire visible light spectrum. Since 2017, Leyard has been collaborating with Saphlux to explore the integration of QDs and Micro-LED technologies to address reliability and efficiency issues in high-brightness applications. Saphlux achieved this by loading QDs into nano-porous GaN to create the NPQD® color conversion layer. This layer was then bonded to a blue LED to produce QD Micro-LED chips with pure and stable colors, as well as high conversion efficiency. In 2022, Saphlux and Leyard jointly completed the development and validation of the display powered by NPQD® R1 Micro LED chips. In 2023, based on NPQD® technology, Saphlux and Leyard achieved significant breakthroughs in both major display technologies--QD technology and Micro-LED technology--and initiated commercialization.
Today, with the endorsement of the Nobel Prize in Chemistry, QD Micro-LED display technology is positioned to replace traditional LCD and OLED technologies across various applications, including large-sized displays, automotive displays, VR headsets, and AR glasses. We believe that in the near future, products combining these two technologies will spearhead a revolution in display technology.
