Interview with Nanosys

A person wearing glasses and a blue shirt AI-generated content may be incorrect.Ahead of Phosphors & Quantum Dots Industry Forum, we spoke with Dr. ZhongSheng Luo, VP&GM, Application Development, Products and Revenue at Nanosys, to get a sneak peek of what we can expect from his presentation on ‘Pushing the Limits of Quantum Dots: Brighter, Purer, Tougher and Lower Cost for Displays’.

Here's what he had to say...


1. Why did you choose the topic “Pushing the Limits of Quantum Dots: Brighter, Purer, Tougher and Lower Cost for Displays”?
      As a perfect light-emitting material, quantum dots are one of the most versatile and powerful materials in displays. However, many people may underestimate how much efforts and innovations it has taken the quantum dots technology from early R&D to initial commercialization and a sustained business success. In addition, the potential for QD in display is still far from fully realized. I wanted to frame my talk around four attributes: brightness, color purity, robustness, and cost, because those are the areas where we continue to see both rapid progress and meaningful challenges. Each of these qualities is essential for meeting the real-world demands of consumers, whether it’s HDR on a TV, visibility in a car display, or efficiency in a mobile device. My goal is to show how advances in materials, processing, and system integration are converging to expand the value quantum dots bring to displays.

2. How do you see quantum dots evolving in the display industry over the next 3–5 years?
       We are at an inflection point. In the near term, I see quantum dots becoming even more deeply embedded across the display ecosystem. Not just in premium TVs, but also in monitors, tablets, and automotive displays. We’ll see higher-efficiency, higher-reliability QDs that allow brighter and more immersive HDR experiences with lower power consumption. At the same time, the manufacturing infrastructure has matured, enabling scalable and cost-effective deployment. Over the next five years, I expect QDs to shift from being a “special feature” to a baseline technology in advanced displays, in much the same way LED backlights became standard. In addition, I also expect you will see commercial products employing QD color conversation (QDCC) technology, especially for some automotive applications and public information displays (indoor). Furthermore, I also expect to see some trial production of the QD electroluminescence (QDEL) technology for certain niche applications.
 
3. What role do phosphors still play in the era of OLED and QD technologies?
      Phosphors are complementary to QDs, not simply competitors. There are many ways the two technologies can collaborate to create better products. In fact, many successful products already combine phosphors and QDs today. The industry benefits from having both toolkits available.
 
4. Where do you see the biggest challenges right now—materials, cost, scalability, or environmental aspects?
       In many ways, we’ve already overcome the challenges that once defined this field. At Shoei, we have scale. Our factory can deliver QDs for more than 40 million TVs per year. Cost will always be important for any consumer electronics product, and the latest generation of our QD diffuser plate technology delivers more performance at a lower cost, now matching the brightness of QDEF. And we have resolved regulatory concerns. RoHS compliance is well-settled with a range of heavy metal free QD options delivering excellent performance.
So instead of a single “biggest challenge,” I’d say the real task now is pushing all three strengths forward simultaneously:
  • Scaling up even further to reach not just TVs but monitors, notebooks and automotive.
  • Driving down the implementation cost while maintaining or improving performance
  • Bringing the technology to a new level such that it brings the best visual experience to the viewer at the most affordable cost
Our strength in each area gives us confidence but also raises the bar for what’s possible in the next generation of displays.
