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.

Quantum dot LEDs (QD-LEDs) have been actively researched due to the potential impacts to display and lighting industry. A considerable future task is to substitute Cd-containing QDs with other, preferably less toxic materials such as InP-based QDs. Here, we investigated the performance of inverted QD-LEDs fabricated with tailor-made multi-shell InP-based QDs and ZnO nanoparticles. The maximum current efficiency and luminance of red QD-LEDs with an emission wavelength of 610 nm reached over 10 cd/A, 20,000 cd/m², respectively. The luminance values are the best records among the reported QD-LED performances using InP-based QDs, and it is now comparable to Cd-based QD-LEDs.

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.

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.
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.
