Session I: The Industry Now and Tomorrow

An overview of the current market, market drivers, trends and future considerations.

  1. Keynote: New Activity Around Quantum Dot Technology

    Jason Hartlove | President and CEO of Nanosys

    In 2018 Quantum Dot technology entered the mainstream TV market for the first time with several great Quantum Dot display products available to consumers for well under $1,000. This major adoption milestone is the result of over 30 years of academic and commercial development from the earliest discoveries at Bell Labs until today. It’s also just the beginning for Quantum Dots.

    What’s next for this novel nanotechnology? Jason Hartlove, CEO of Quantum Dot leader Nanosys, shares his vision for the next phase of Quantum Dot technology development - including future display applications and a look at how Quantum Dots will begin to change other industries such as lighting, agriculture, and sensors over the next decade.

  2. Emerging Display Technologies and Impact for Downconverters

    Dr. Eric Virey | Senior Market & Technology Analyst of Yole Développement

    After LCD won the battle against plasma, the display industry is once again on the verge of a technology revolution. However this time, rather than a duopoly, there seem to be a proliferation of highly credible emerging technologies. The presentation will discuss the major contenders such as White OLED, RGB OLED, emissive and electroluminescent Quantum Dots, miniLED, microLED etc. Strengths and weaknesses as well as the technology development status and industrialization perspectives will be discussed with a particular emphasis on the role played by downconverters (phosphors, Quantum Dots or Perovskites) for each of those technologies.

Session II: Capabilities and Opportunities

This session will focus on the capabilities of Phosphors and Quantum Dots.

  1. Are There Limits for Narrow Band Phosphors?

    Dr. Daniel Bichler | Senior Key Expert Phosphor Design of OSRAM Opto Semiconductors

    Narrow band phosphors are a key technology for many conversion applications today. Such phosphors allow tailored spectral design and efficacy improvements. However, the emission of most phosphors currently considered ‘narrow band’ still limits the application performance of LEDs. OSRAM’s highly efficient R&D approach enabled the discovery of groundbreaking new ultra-narrow band phosphors. They show much narrower emission bands than established ‘narrow band’ phosphor materials. Several unique new materials will be presented and their application potentials discussed. They enable enhanced flexibility in future LED design, potentially surpassing existing technologies. 

  2. Coffee and Networking Break

  3. Monolithic Phosphors for High Lumen Density LED Sources

    Dr. Henri Jagt | R&D Manager - Light Sources & Materials of Signify

    In the transformation in the Lighting Industry from conventional to LED, one of the most difficult areas to implement LED technology is the area of high brightness light sources. For this purpose, new breakthrough High Lumen Density (HLD) LED technology was developed by Signify that makes use of light extraction from monolithic phosphor rods (green/yellow) that are pumped by arrays of blue LED sources. The requirements, benefits and challenges of such monolithic converters will be discussed. With this technology, high luminance levels (1-2 Gnits) were realized combined with high source outputs to result in LED based light sources for mainstream 2000 – 4000 Alm digital projectors.

  4. Narrow band Green Phosphors Enabling Wide Color Gamut Displays

    Dr. Jonathan Melman | Co-Founder of Lumenari

    Quantum dots have attracted attention over the years for many reasons. One such reason is the potential for narrow full-width-at-half-maximum (FWHM) of the photoluminescent emission, and the wide color gamut that would enable in display applications. The FWHM of the green downconverter plays a pivotal role in that gamut, as a narrower FWHM results in a more saturated green color and thus, a wider gamut. Lumenari’s novel class of efficient phosphor, Emerald, exhibits a narrow FWHM less than 40 nm, rivaling InP quantum dots, and is tunable between 505 nm and 545 nm. This talk will discuss how Emerald, when paired with an appropriate red phosphor, is capable of delivering gamuts on par with quantum dots.

  5. Networking Lunch

Session III: Novel Opportunities

This session will explore ways that Phosphors and Quantum Dots can be used beyond traditional lighting and display.

  1. Wide-Gamut Displays Without Blue Radiation

    Dr. Aurelien David | Chief Scientist of Soraa

    The physiological effects of blue radiation have recently spurred device manufacturers to seek                low-blue, "human-centric" alternatives for lighting and displays, but conventional approaches        require a low-CCT colorpoint. Here, we introduce a unique approach to generate white light       spectra where violet replaces blue radiation; these spectra have a melanopic lumen output (a          metric of circadian entrainment) 30-40% below conventional spectra at the same CCT. We then            demonstrate how these spectra can, despite the lack of blue radiation, be configured to obtain a          wide-gamut display. Our results enable dynamic control over circadian stimulation without          sacrificing color gamut or visual experience.

  2. Can Human Performance be Improved by Light?

    Dr. Sadakazu Wakui | Phosphor Engineer of Nichia

    In the general lighting market, a large efficacy gap has stymied the transition from 80 CRI to 90+ CRI. 80 CRI has been widely adopted, being deemed acceptable throughout most of the market. To encourage the further growth of the lighting market, additional features and benefits are necessary, without sacrificing luminous efficacy. As one additional feature, Nichia has focused on and researched the effects that the spectral shape has on eye fatigue. Channeling its 50+ years of phosphor experience, Nichia has developed an innovative LED which reduces visual fatigue and increases human work efficiency, all with a minimal efficacy drop. This LED ideal for office and educational facilities.

  3. Horticulture LEDs and Phosphors: Lighting the Farms of the Future

    Eden Dubuc | Current, Powered by GE of Senior Technology Architect, Horticulture Lighting

    Greenhouses and vertical farms are helping feed the world by enabling farming in tough climates and food deserts. LED lighting is a key element of these innovative farms and plants are an entirely new lighting customer. LEDs, and specifically the role of phosphors in horticultural lighting represent a fascinating branch of research and development rife with opportunity. Join Eden Dubuc, a horticultural lighting expert at Current powered by GE to discuss where these technologies are today and where they could lead us in the future. 

  4. Agricultural and Medical Use Cases Enabled by CIS QDs

    Hunter McDaniel, Ph.D. | Founder and CEO of UbiQD, LLC

    Quantum dots (QDs) have seen significant market success as narrowband emitters for displays, but have had limited penetration into the many other applications areas due to reliability issues, high manufacturing costs, and toxicity concerns. UbiQD has developed a new class of QDs based on copper-indium-sulfide (CIS) that largely solve these issues. These dots have a novel copper-defect-based photoluminescence mechanism that has some characteristics of phosphors, but they still exhibit size-dependent emission. As such, these materials are better-suited for non-display applications, and UbiQD is currently focused on improving the quality of sunlight in greenhouses. This talk will highlight the recent developments including data from several plant trials, and an overview of the first-ever QD greenhouse film product called UbiGro. Additionally, a QD-based medical diagnostic light source will be introduced and new CIS QD cytotoxicity data will be shared.

  5. Coffee and Networking Break
