MicroLED technology is on its way to replacing traditional display technologies by bringing added value propositions to the consumer market, including high brightness, excellent lifetime, high resolution, and superior efficiency, with applications spanning from wearable devices, augmented/virtual reality, and ultrahigh-definition TVs. To date, challenges in scaling pick-and-place processes and producing highly efficient red and green native microLEDs hamper microLED mass production. A quantum dot (QD) color conversion strategy to produce an RGB display from an array of blue microLEDs is an elegant way to simplify the manufacturing process and to overcome several technological challenges in the mass-transfer process, the display brightness, and the driving electronics. QustomDot’s mission is to bring unmatched colors to micro-LED devices through QD color conversion layers to overcome the challenges above and facilitate market entry of miroLED-based devices. Over the past few years, QustomDot has made a giant leap towards QD resins containing Cd-free RoHS-compliant InP QDs. Our focus has been to formulate QD resins with ultra-high solid loading, excellent shelf life, and processability, adapted for various processing methods, including photolithography, nano-imprint lithography, and high-precision printing methods. In addition to excellent processability, our QD resins result in QD films with high solid loading, excellent absorption at the sub-10 µm thickness, and high conversion efficiency while matching, if not exceeding, the reliability of commercially available InP-based QDs. Our talk will showcase our recent progress towards optimization of our red and green QD resins to obtain color conversion films with optical properties one step closer to fulfilling the challenging requirements of commercial microLED displays.

Alexander Goerk Business Development Manager Diode lasers are by far the most efficient method to introduce thermal energy into NIR absorbing materials. Fortunately, most conductive inks absorb the 940nm of the Hamamatsu cw SPOLD laser, allowing a homogeneous and rapid sintering result comparable to other thermal post-processing technologies. The use of laser line optics favours scalable, yet highly sustainable high volume production, for example in an R2R machine or ITO Touch display manufacturing. Hamamatsu's own developments in terms of lasers and optics make it possible to adapt to customer-specific requirements, materials and processes.

GE Healthcare is a global company that has been operating for many years, with almost 50,000 employees and a revenue of almost 20 billion dollars. The company is best known for its medical imaging devices, but one of its business units, Monitoring Solutions, is focused on manufacturing multi-parameter monitors for operating rooms and intensive care units. Recently, GE Healthcare established a smaller unit that focuses on wearable patient monitoring, which is the department that will be discussed in this video. Patient Monitoring in Hospital: In an intensive care unit, a sedated patient is connected to many cables and tubing to measure various parameters. The nursing staff is interested in knowing whether the tissues are properly oxygenated, whether the medication is correct, and whether other vital organs are functioning well. Therefore, lots of information is required to answer these kinds of questions. On the other hand, in general wards, patients are not monitored at all. The vitals are checked once or twice a day, which is a recognized problem since incidents may happen. Wearable Patient Monitoring: The wearable patient monitoring department of GE Healthcare has recently released a product called the Portrait Mobile Monitoring Solution. It includes two wireless transmitters, one measuring the respiration rate, and the other measuring the blood oxygen level. The system also includes a small mobile phone-like patient monitor that can be used in standalone mode or transmit data to the hospital server. Why Respiration Rate and Blood Oxygen Level? Respiration rate has been recently recognized as a very good early indicator of patient deterioration, and there are a good number of articles on this topic. The respiration rate can be measured in many different ways, but GE Healthcare chose to use bio-impedance, a very traditional way used in EKG devices, to capture the body movement. The reason behind this choice was that it provides much better reliability than other methods like breathing belts. How Was Respiration Rate Measured? To get an accurate respiration rate and low alarm burden, GE Healthcare started by mapping the human body to understand where to get the best possible signals for respiration rate calculation. They used EIT devices to scan the whole body and chose three electrode locations, two leads, or two channels, to capture the thoracic and abdominal breathing effort. Then, on the algorithmic side, GE Healthcare developed an algorithm to remove the cardiogenic component from the impedance signal, which captures everything and makes up near detection very difficult. Conclusion: The wearable patient monitoring solution developed by GE Healthcare provides continuous signals, and the device can alarm on life-threatening events almost immediately. This is very different from wellness devices that can provide very good trend information but are not suitable for medical analysis. The wearable patient monitoring solution is a standalone device that provides a full feature patient monitor and can transmit data to the hospital server. The focus on respiration rate and blood oxygen level is crucial since they are early indicators of patient deterioration, and GE Healthcare used bio-impedance to capture the body movement, providing much better reliability than other methods.

Author: Tsuyoshi Takeda, Panasonic The Electronic Materials Business Division of Panasonic Industry Co.,Ltd. (Panasonic) is a premier supplier of electronic materials like printed circuit boards laminates, semiconductor packaging materials, display films and other leading-edge products. Leveraging our core expertise in high-performance thermosetting polymer chemistry, we developed BEYOLEX™, a fully cross-linked, non-silicone, thermosetting stretchable film. BEYOLEX™ is specifically designed as a soft, stretchable, and durable substrate for reliable printed electronics. BEYOLEX™ exhibits superior performance when compared to existing stretchable films like Thermoplastic Polyurethane (TPU) and Polydimethylsiloxane (PDMS) and is under evaluation and qualification for a wide variety of demanding applications. In collaboration with our innovative partners, Panasonic introduces our latest case studies on soft circuit development which is one of the promising applications of BEYOLEX™. Case Study 1: Pliable PCB made with copper sintering ink InnovationLab and Panasonic developed a pliable PCB demonstrator. This device was designed and manufactured by InnovationLab using BEYOLEX™ and sintered copper ink. Generally, the copper inks require a high sintering temperature (>160 °C), which is extremely challenging for TPU. As can be seen in Pic 1, the BEYOLEX™ substrate had no difficulty tolerating the sintering temperature and exhibited no damage from the process. Furthermore, the combination of the high temperature tolerance of BEYOLEX™ and the solderability of the sintered copper ink enabled component mounting with standard solders such as Sn-Bi or SAC305: resulting in reliable and high density assemblies and delivering a functional PCB with more pliability and softness than typical flexible printed circuits (FPCs.) Pic 1: Pliable PCB made by InnovationLab Case Study 2: Stretchable hybrid PCB made using copper ink and stretchable silver paste Kelenn Technology, a leading manufacturer of printing equipment, also makes functional inks that are customized for their printing systems. Using their proprietary Direct Material Deposition (DMD) technology, Kelenn Technology printed land pads with copper ink and circuit traces with stretchable silver-based paste onto BEYOLEX™ film (Pic 2). This hybrid circuit produced a solderable, stretchable PCB configuration that would be difficult to achieve with copper circuitry alone. Definitely, BEYOLEX™ is the only substrate solution for this design. Pic 2: Stretchable PCB made by Kelenn Technology Subsequently, Panasonic engineers reflowed solder paste onto test vehicles prepared by Kelenn Technology. We printed an industry standard SAC305 solder paste and reflowed the part in a Vapor Solder Oven with a temperature of 230°C. We confirmed both the solderability of the copper ink pads provided by Kelenn Technology as well as the mechanical integrity of BEYOLEX™ after soldering (Pic 3). As a result of this test, we believe BEYOLEX™, with sintered copper ink, is a promising solution for solderable, pliable or even stretchable PCB constructions. Pic 3: Soldering on Cu Case study 3: Tackling the challenges of truly stretchable electronics Stretchable silver pastes are an attractive conductor solution for new form factor devices. However, these polymer composite pastes have inherent limitations for forming truly stretchable electronics; typically, the resistance increases significantly with each elongation cycle and these increases are cumulative, climbing with each stretch cycle. A printable Liquid Metal Based Composite developed by University of Coimbra (UoC) is a promising solution to this issue. UoC’s ink exhibits metallic conductivity and much lower resistance change during stretch cycles compared to silver-polymer pastes. Thanks to the lack of plastic deformation of BEYOLEX™, UoC’s ink printed on BEYOLEX™ looks to be a promising combination for truly stretchable electronics requiring repeated stretching (Pic 4). Pic 4: Stretchable LED with capacitive touch by UoC The soft-circuit solutions made with BEYOLEX™ introduced in this article are made by additive printing processes which are generally more environmentally friendly than the conventional subtractive PCB fabrication process. Panasonic’s Electronic Materials Business Division keeps contributing to create value and to society through innovative materials.
