  1. Environmentally Friendly Quantum Dots for Display Applications

    Dr. Eunjoo Jang | Samsung Fellow of Samsung Electronics

    Ever since the physics of quantum dot (QD) materials was discoverd, much research effort has been carried out for more than 30 years, and lots of applications adopting QDs have been proposed. Especially, wide color gamut displays using QDs as active light emitting materials have drawn much attention from the academia as well as the industry.  And, the QD-based consumer displays such as LED TVs, tablets, and special monitors are now on the market.  They provide best color gamut, reasonable power efficiecy, and affordable price showing superior competitive edge to OLED technology.  However, up to this point, still there are issues and argues using Cadmium containing materials in practical consumer devices.  In spite of the European RoHS Exemptions, we need to be aware the environmental risk of producing large quantity of Cd-containing materials and using them in the consumer electronics.  And, this growing apprehension for environmental issues formed great limitation for QD’s applications.  Therefore, we have dedicated to develop more environmentally friendly InP based QDs that showed considerably high efficiency and saturated color spectrum compared to the Cd-containing materials.  The structure of Cd-free QD was specially tailored for display applications and the synthetic process was optimized to produce reliable materials in commercial scales.  In order to improve the efficiency and stability of the QDs in the devices operating under severe atmosphere, specific composite materials were designed and the fabrication process was optimized.  From 2015, Samsung has released Cd-free QD adopted UHD TV for major product line-up which show the best color gamut among the current displays. Now we are trying to make additional breakthroughs in displays by using established QD technology and broaden the technology to wider optoelectronic applications.

    Matt Bergren | Vice President of UbiQD

    In recent years, quantum dots (QDs) have gained interest as narrowband emitters for displays, but have not traditionally been incorporated into products beyond displays. At UbiQD, we envision making QDs ubiquitous across many industries with a new kind of QD that is intrinsically more stable, lower-cost, and avoids toxic compounds. We are currently focusing on bringing to market QD-tinted luminescent solar concentrators (LSCs) that enable electricity-generating windows and optimize greenhouse agriculture. I will highlight the unique optical properties of our QDs and recent LSC developments.

    QD Solar Inc. develops colloidal quantum dot-based solar cells that absorb infrared light which silicon solar cells cannot harvest. QD Solar’s solar cell sheets can be seamlessly integrated into a solar panel manufacturing process to boost the overall power generation by >20%. Adding this game-changing lightweight performance-boosting technology to silicon solar modules will decrease the cost of electricity.

  4. SWIR, X-SWIR and MWIR Nanocrystal Imagers

    George M. Williams | President, and Chief Executive Officer of Voxtel Inc.

    George Williams (CTO and President, Voxtel, Inc.) will present an environmentally-robust, air-stable, colloidal nanocrystal quantum dot wafer scale infrared imaging array device technology for the shortwave infrared (SWIR), extended SWIR (XSWIR), and midwave IR (MWIR) spectrum that operates at or near room temperature. This platform is manufacturable using high rate solution-based synthesis and deposition for three order of magnitude system cost reductions vs conventional IR imagers while delivering comparable imaging responsivity and D* performance.

    Our imagers can be effectively deployed as 1) higher resolution passive XSWIR low light level (LLL) imagers, 2) laser spot imagers, and 3) lower cost SWIR imagers. We have demonstrated the ability to control doping, deposition and photodiode device processing, thus combining the best attributes of crystalline semiconductor CMOS processing and large, scale LED and OLED display manufacturing. We have demonstrated the ability to create 1280 x 1024 (SXGA), 5-micron pixel; 1980 x 1280 (HDTV), 9-micron pixel; and 640 x 512, 25-micron pixel dual-mode (simultaneous passive and laser spot) imagers. Organic and inorganic ligand passivation with p-type and n-type quantum dot doping, when combined with interfacial engineering in tight, regular packed solids, with infilling of the void space with smaller-bandgap semiconductors, make possible rapid charge and relatively long distance charge transport with efficient injection and extraction. Engineering control over the band structure makes it possible to perform detector device engineering in a fashion common to crystalline semiconductor detectors.

    The LED industry is maturing and entering a new growth cycle driven by high added-value applications such as Human Centric Lighting, automotive or horticultural lighting. A common trend across those applications is an increasing need for higher efficiency and complex spectral engineering. Downconverters are one of the most critical components to achieve those goals. Yet, the phosphor industry is experiencing growing pains and strong revenue pressure due to fierce competition. At the same time, quantum dots are finally transitioning from a 2 decade long research project into a multibillion dollar industry driven by display applications.

  9. Uniformly Dispersed and Stable QD/Siloxan Resin for Display Applications

    Byeong-Soo Bae | Founder and CEO/ Professor of Solip Tech. Co., Ltd., Korea / KAIST, Korea

    Dispersion of QD in polymer resin and stability of its curing products over heat and moisture are key issues for practical applications of QD-base displays. We have developed uniformly dispersed QD in siloxane resin by in-situ sol-gel condensation of organo-silanes mixed with QD. Dispersion stability is almost permanent to uniformly coat or dispense. Its cured films are extremely stable at high temperature and humidity environments. Also, they are stable over photolithography chemicals and plasma illumination. Photo-stability can improve by modifying QD synthesis and siloxane resin composition. Thus, it can apply to phosphor resin in BLU LED encapsulation, color filter, and MicroLED display.

  10. Color Converter Novel Materials

    Philippe Gounine | Deputy CEO of NEXDOT

    Nanoplatelets have unique optical and electronic properties: they are fluorescent with a color purity that cannot be matched by other phosphors or fluorophores. In addition, their fluorescence lifetime is faster than in other type of nanocrystals and their electronic density of states is continuous, which results in brighter fluorescence when multi-excitonic states are present. We will present this novel material with a focus on novel properties and applications when used as color converter.

  11. Networking Break & Afternoon Refreshments
