- At Display Week 2024, Nanosys' booth showcased the significant advancements in quantum dot technology, particularly focusing on quantum dot electroluminescent (QD-EL) displays. Jeff Yurek, Vice President of Marketing, highlighted that this year marks a pivotal moment with multiple demos of QD-EL displays from companies like TCL, Samsung, and Sharp. These demonstrations represent years of anticipation and development in the quantum dot industry, moving from initial glowing pixel prototypes to fully functional displays that are close to commercial viability.
One of the significant milestones discussed was Sharp's announcement of a 100,000-hour blue quantum dot lifetime. This breakthrough addresses the longstanding challenge of achieving long-lasting blue emissions, which is crucial for the viability of quantum dot displays. Yurek mentioned various strategies to enhance the lifespan and performance of these displays, such as using multiple layers of blue pixels or increasing the pixel area to reduce current requirements. These innovations bring the industry closer to producing durable, high-quality quantum dot displays.
Nanosys did not present its own displays but showcased the advantages of quantum dot technology, particularly its speed. Quantum dots are the fastest lighting phosphor materials available, which significantly benefits applications requiring rapid light emission, such as gaming and professional displays. Yurek contrasted this with slower competing technologies like KSF phosphors, which can cause color lag and artifacts. By collaborating with experts like Mark Rejhon from Blur Busters, Nanosys developed tests that visibly demonstrate the superior performance of quantum dots.
The company also introduced a new version of its technology called XQF, a cost-effective, air-stable quantum dot diffuser plate that enhances TV performance across various price ranges. This innovation makes high-quality quantum dot displays accessible to more consumers, even in lower-priced TV models. Yurek noted that this broad accessibility is transforming the market, making it almost nonsensical not to opt for quantum dot-enhanced TVs due to their superior performance.
Quantum dot OLED (QD-OLED) technology was another highlight, with new models leveraging blue OLED stacks and quantum dots to achieve exceptional color reproduction and brightness. The use of tandem stacks, consisting of multiple OLED layers, allows for brighter and more efficient displays. This technology addresses challenges such as the accurate representation of difficult colors and enhances overall display quality, making QD-OLEDs highly attractive for both consumer and professional markets.
The discussion also touched on the practical aspects of manufacturing quantum dot displays. While OLED manufacturing is costly due to the need for vacuum environments, quantum dot displays can potentially be produced using existing LCD manufacturing infrastructure. This compatibility with current equipment could significantly lower production costs and leverage the vast installed capacity for LCD manufacturing, accelerating the adoption of quantum dot displays.
Nanosys' recent corporate developments were also featured, including their acquisition by Shoei Chemical in 2023 and the opening of the world's largest quantum dot factory in Oshima, Japan. This new facility, operational since January 2024, represents a major investment in the future of quantum dot technology. It underscores the commercial success and growing demand for quantum dots, driven by their application in various fields beyond displays, such as agriculture, solar energy, and biological applications.
Finally, the Nobel Prize in Chemistry for 2023, awarded for the invention and commercialization of quantum dots, was celebrated. The prize highlighted the profound impact of quantum dots on consumer electronics and their potential in other industries. The award recognized both the scientific innovation and the practical applications that have emerged, demonstrating the broad significance of quantum dot technology in modern science and industry.

This is a terrific video! I learned more about Nanosys and their quantum dot development effort from this video alone than form all others that I have seen. Excellent work!
Wow, I did not know that Nanosys goes back that far. And their enhancement film was developed in Cleveland. That's my neck of the woods!
Nanosys singlehandedly carrying the display market. Absolute GOATs
I'm 47 and a film nerd/display enthusiast, so I can easily recall when quantum dots were just a whisper in the industry. And now we have them in nearly every consumer display at affordable prices. 2023 and 2024 are the breakout years that miniLED is really giving OLED's perfect blacks a decent run for their money, especially in brighter rooms. The fact that you can get a 65" LED that is better than almost anything on the market from just a few years ago for such a bargain is wonderful. Now with Sony releasing their new Backlight Master Drive tech for the Bravia 7/9 series, 2024 is going to be another epic year to be a display enthusiast. We've come a long way since the 480i lines of NTSC I grew up with!
Great video thanks
CRT like motion Clarity out of a display that doesn't require vacuum? Come on self emissive quantum dot!
How long do Quantum Dots last before they deteriorate? I have a Sony from 2014 and it probably has 20,000 hours on it. It still looks new in terms of performance.
TV brands typically require reliability of 30,000 hours to 80% initial luminance. QDEF can achieve 100,000 hours. Typically other things will fail first.
@@NanosysInc Thanks so the TV may have lost some of its luminance, right but should be over 80%.
Do you know if it has Quantum Dots or Phosphors? I know Sony switched either after 2013 or 2014.
@@techsamurai11 The 2013 XBR-X900 had an early QD component for LCDs in which QDs were encapsulated in a glass tube affixed to the LEDs at the edge. This was produced by QD Vision. In 2014 they switched the Triluminos brand to phosphor and came back to QD with QDEF LCD as well as QD-OLED in 2022-23.
*Ask him does nanoLED match the brightness of QD-OLED?*
Not yet! The nanoLED displays shown at Display Week were in the 100-250 nit range. But... emissive quantum dot pixels have been produced with >600,000 nit luminance so nanoLED displays definitely have the potential to get pretty bright!
@@NanosysIncwhat is the pixel response time of nano led ?
@@NanosysInc *100-250 nits at what window?*
@@charliewright1009 a few nanoseconds

We have a system that can eliminate color blindness in those who look at the monitor for a long time. Our beautiful children are safe.
