    David Wyatt | CTO of Pixel Display

    Light, color, contrast are the key elements of communication, and today the portable device display is the dominant communication portal. The challenges for modern displays are increasingly complex, but the rewards of prolifically making visual interfaces colorful, bright, efficient and healthy, can be enormous. Looking ahead we see ever more exciting opportunities in the faster than Moore’s law growth of visual technologies, and in the elemental source of this revolution: the materials. This presentation will recap on some of the leading-edge developments, the gaps in the value chain, the challenges and key factors for success, and explore some possible options.

  2. Realizing the Promise of Micro LED Displays

    Khaled Ahmed | Global Supply Chain & Technology Development, Principal Engineer of Intel Corporation

    The demand for low power in mobile devices has increased dramatically in the past ten years due to limited battery lifespan. One of the components with the highest percentage of total power consumption, and therefore a suitable candidate for improvement, is the display. Inorganic µLEDs have a number of potential advantages over organic LEDs (OLEDs) for display applications. These include the possibility of high brightness and higher power efficiency. In this talk, the ecosystem components of micro LED displays will be discussed including the potential need for color conversion materials such as quantum dots.

  3. PFS/KSF Phosphor in Display and General Illumination Applications

    Dr. Bill Cohen | PFS Business Leader of GE Current

    Starting when GE launched the technology in 2014, PFS/KSF Phosphor filled the void for an efficient, on-chip red luminescent material desired in both display applications seeking wider color gamut performance as well as general illumination applications desiring high-efficiency lighting with truer color rendering of illuminated areas and objects.  With PFS/KSF Phosphors in display devices, LEDs illuminate with a truer saturated red yielding vivid red colors while reducing yellowing of the green pixel emission.  In general illumination, the technology has enabled lighting products with 90CRI and R9>50 at the same/better lumen efficiency as 80CRI products starting with products launched in 2015.  Moreover, the technology is well suited for high-quality, high-efficient lighting as evaluated with evolving color standards (e.g. TM-30).   Significant progress has been made to enable more challenging applications for these fluoride Mn4+  phosphors in terms of both cost and reliability.  Today’s use of this technology as well as areas of development, innovation, and expansion for PFS/KSF Phosphor will be discussed.

    Dr. Chaoqun Yang | Development & Application Engineer, QD Technology of CSOT (China Star Optoelectronics Technology)

    We have developed a scheme to make small size QD (quantum dot) display come true. It is different from QD enhancement film which is used in backlight, our work focus on developing QD color filter. Compared with traditional LCD, the brightness and color purity of QD-LCD have been greatly improved. In our development projects, the QD Color filter is realized through the lithography process and we got wide color gamut up to 99.2%BT2020 (equal to132.86%NTSC) in Cd based QD, and 93.6%BT2020 (equal to 125.35%NTSC) in Cd-free QD. In this communication we focused on the explaining architectural principles used during design and implementation.

  7. Optimizations of Quantum Dots and Device Structures to Improve the Lifetime, External Quantum Efficiency and Reproducibility of Quantum Dots Light Emitting

    Dr. Wenyong Liu | Display Expert of TCL

    Motivated by the new wave of AMOLED technologies which has been successfully applied on smartphones, TV sets and other electronic products, quantum dots light emitting diodes (QLEDs) also embrace augmenting attentions. QLEDs, compared to OLEDs show better opto-electro properties including short full width at half maximum, high quantum yield, potentially long stability. Here in TCL research center, we dedicated to focusing on QLEDs as out next generation display technology. Currently, we TCL incorporation successfully built a complete QLEDs platform from QDs design and synthesis, then to device fabrication and performance test, then to 31’’ display panel demonstration, up to the Gen 8.5 production line and finally to the TV sets terminals. All together are integrated onto the same platform, with the goal of commercializing QLEDs in near future. In this speech, I will focus on the steps and procedures employed to improve the QLEDs performance and stability.

Session III: A look at Lighting

This session will feature presentations focused on how the use of highly engineered color conversion materials in lighting applications can lead to the design and commercialization of novel LEDs.

  1. Novel Color/Spectral Tunable LED Helps to Organize Our Circadian Rhythms

    Dr. Sadakazu Wakui | Engineer of LED Back-End Material Engineering Department of Nichia

    In the general lighting market, the transition from CRI80 to high CRI LED is slower than expected because of existing efficacy gap. To encourage further growth of the market, Nichia believes that additional features will be needed, without decreasing the efficacy. In this forum, we will discuss the original concept and the research used to prove out this new color/spectral tunable LED which can tailor both CCT and melanopic spectral factor to match our circadian rhythms without the efficacy dropping. We believe that this LED will help to control disordered sleep and decrease eye fatigue. Hence, this will be suitable for educational, health care facilities and manufacturing environments.

  2. Full Spectrum Artificial Lighting and Virtual Windows for Human Health and Well-Being

    Dr. Partha Dutta | Professor of Electrical, Computer and Systems Engineering of Rensselaer Polytechnic Institute

    Recent research correlating the cognitive psycho-physiological health of human beings and their interactions with nature and natural light conditions are clearly indicating the important role of windows with external views on the productivity and well-being of building occupants. Providing access to outdoor views and natural lighting to every occupant in a building is a daunting task for architectural designers and often cost prohibitive when accounting for energy efficiency of the buildings. This talk will present the design and operation of emerging LED-LCD based virtual window systems. A new approach for designing tunable spectrum phosphors and phosphor based LEDs for virtual windows and full spectrum lighting applications will be discussed.

  1. Combining Phosphors and Quantum Dots: On-chip Operation and Solution Tailoring

    Sebastian Stoll | Development Engineer of OSRAM Opto-Semiconductors

    Solid state lighting-based phosphor-converted LEDs have evolved over the last two decades as the driving force in the general illumination market. Improvements in efficacy and product quality have been the main objective. Enhancing these poses a particular challenge as the maturity of conventional LED phosphors has progressed tremendously, and the limits are becoming apparent. Additionally, the quality of light with properties like CRI and FCI is becoming more and more important.By developing red-emitting Quantum Dots (QD), encapsulated to face harsh external influences such as moisture and thus enabling on-chip operation, and combining them with LED phosphors, OSRAM Opto Semiconductors pushes the limits of high-CRI white LEDs. The narrow band emission of QDs together with the high variety of LED phosphors enables flexible engineering to maximize spectral efficiency and thus boost product efficacy. Due to the ability to spectrally tune the QDs e.g. by changing the size, more applications can be envisioned.  This presentation will give insights in the interplay of phosphor and QDs in solution tailoring, procedures that enable on-chip operation and additional applications enabled by this beyond general lighting.

  4. Towards Future Display Technologies: On-chip Grade Quantum Dots

    Willem Walravens | CTO & Founder of QustomDot

    Quantum Dots (QDs), the nanocrystals that can downconvert light with high efficiency, are on their way to revolutionize display and lighting applications. However, the widespread use of QDs is limited by two issues. As cadmium is restricted by RoHS, the use of cadmium-based QDs is limited. Second, the Cd-free alternatives deteriorate quickly under high temperatures and light flux conditions. At Ghent University we’ve developed a Cd-free technology that can withstand these harsh conditions and can be used directly on the LED chip. This opens new possibilities for QDs that are being explored by the spinoff company QustomDot.
