"ams Osram has announced a series of 2835 (2.8×3.5-mm) LEDs under the Osconiq brand including an emitter that uses quantum dot (QD) technology to more efficiently deliver excellent color rendering and warm CCTs. The new series further includes an LED with a cyan peak intended for lighting for health and wellbeing or circadian lighting applications. An 80-CRI mem2ber of the family for commercial and industrial (C&I) lighting applications completes the new series." "The 2835 opportunity has certainly caught the attention of LED manufacturers. Lumileds just announced higher-performing 2835 LEDs a few weeks ago and that was after a similar performance push in February. Osram has previously offered 2835 LED in its Duris family of LEDs that target mainstream, specification-grade lighting products. The Osconiq family generally targets architectural, professional-grade luminaires." "The three LEDs in the Osconiq E 2835 series cover a breadth of potential deployments in the C&I and adjacent application spaces. The standard Osconiq E 2835 CRI 80 is a component that can serve in mainstream C&I applications and that would allow a luminaire manufacturer to offer a product line with luminaires varying in color quality that all use LEDs from the same family. The company said the 80-CRI component might be used in office and retail applications". "The most significant member of the new series is perhaps the Osconiq E 2835 CRI 90 QD component. The use of QDs in the phosphor formulatio...

Axxicon offers a microfluidic bonding technology guide and webinar to ease the decision of choosing the suitable microfluidic bonding for a high-quality consumable product. Figuring out the key criteria to consider and how several technical choices, at different stages of the process impact each other can be stressful when choosing the right microfluidic bonding technique. As an engineer, you must address design and process issues early to produce a high-quality consumable product. Requirements for the selection of your bonding process Each microfluidic product and application has unique requirements, and the bonding process you choose must meet those criteria as well. Common requirements are: Optical properties
In some applications, it is essential to compromise the optical properties of the consumable like transparency, prevent autofluorescence Chemical and biological compatibility
Biocompatibility, contact of reagents or samples with glues, VOCs Pressure stability
For some applications pressures within the consumable can increase. Channel dimensions integrity
The dimensions of structures like channels or cavities should stay within tolerance after bonding Design limitations
Not all bonding processes might be compatible with all designs. Distance of features, available surface for bonding, this all can be relevant Reagent storage on-chip (before bonding)
For example coatings or bio-reagents can be stored on-chip, but can they also survive the bonding process? Mate...

Electrochromic displays are a rapidly emerging technology in the field of visual interfaces owing to their design versatility and cost-effective production. The technology is ideal for use in smart labels, consumer electronics, logistics monitoring, medical devices, smart cards, retail, and point of service applications "The Ynvisible Segment Display is an electrochromic display. It is categorized as a reflective display - meaning that it reflects ambient light instead of using a backlight. All layers are screen-printed on a plastic substrate. The display stack consists of organic layers including a plastic substrate, an electrochromic material, an electrolyte, and an electrode for each segment. Additional layers such as graphical overlays and circuits may be added if required." "Evaluate the ultra-low-power, thin, and flexible Segment Displays. Each kit contains different display designs and includes a manual display driver as well as a display driver with an I2C interface. "Electronics engineers and enthusiasts alike can now buy Ynvisible displays in several online marketplaces, improving market accessibility to electrochromic display technology."

A team of researchers at Seoul National University's Center for Nanoparticle Research has developed a foldable variant of an ultrathin quantum dot LED (QLED), inspired by the ancient art of paper folding known as origami, and published their work in nature electronics paper "Three-dimensional foldable quantum dot light-emitting diodes" "QLEDs use quantum dots (nanoscale semiconductor particles) for the emission of light. Thanks to their outstanding electroluminescence, they have attracted considerable attention as a candidate for the next generation of display technologies. QLED displays do not require any bulky components such as backlight units, potentially allowing them to be manufactured with ultrathin form factors." "The researchers endowed foldability to the conventional planar QLED via a new fabrication process that can partially etch the epoxy film deposited on the QLED surface without damaging the underlying QLED. Using a power-controllable carbon dioxide pulsed laser and the silver-aluminum alloy-based etch-stop layers, the etching depth can be precisely controlled. As the laser-etched part of the device is relatively thinner than the surrounding region, it is possible to etch out deformation lines along which the device can be folded like origami paper." "Based on the selective laser-etching technique, researchers were able to precisely control the radius of curvature down to less than 50 micrometers. Under such a small curvature radius, the fold line resembles...

"Toshiba, the Japanese world-leader in development of perovskite photovoltaic modules for next-generation solar power generation, has developed a new coating method for the perovskite layer that boosts power conversion efficiency (PCE) to 15.1% for Toshiba’s 703cm^2 module, the highest for any large, polymer film-based perovskite photovoltaic module. The innovative coating method for perovskite layer also greatly reduces production time and costs, contributing to a lower cost for solar power generation." "Success in achieving carbon neutrality will require much greater use of photovoltaic power generation, and a significant expansion in locations where photovoltaic modules can be installed. Today’s most widely used photovoltaic modules are made with crystalline silicon and are heavy, and this, plus their rigidity, limits where they can be installed. The polymer film-based perovskite photovoltaic module is an attractive next-generation alternative, as it is thin, light and flexible, and can be installed in locations where it is difficult to use silicon photovoltaic modules, such as low load-bearing roofs and office windows. Recent improvements in the PCE of perovskite photovoltaic modules has brought them to a level comparable to that of silicon photovoltaic modules." "Toshiba’s latest breakthrough is the development of a new perovskite layer coating method. The company previously developed a two-step coating process that first applied a layer of PbI2 (lead i...

ISBC and Sappi have collaborated to present an innovative new smart paper with embedded RFID chips. The chips are embedded into the paper sheets causing no effect over the paper surface – it remains flat and smooth. "Printed electronics are decidedly on the move. Radio-frequency identification (RFID) is no longer a niche technology. It is already being used to great effect in many areas of everyday life: in our passports, ID cards and travel cards, clothes, library books, and much more. The vast scale and intricacy of the RFID market also offer new opportunities for the printing industry. " "With this in mind, ISBC from Singapore has developed and presented on the market an innovative product: ISBC RFID Paper. The product is sheet-fed and made with 100% fiber-based Swiss Matt paper substrate from specialty paper manufacturer Sappi.
The smart RFID Paper supplier was looking for an alternative to plastic for smart printing and Sappi’s Swiss Matt paper – used mostly as an inkjet paper for large-format printing – was settled on due to its white surface, print results, and scratch- and water resistance. The companies also report that the product is as easy to print as a regular sheet of paper, reportedly making it a cost-efficient solution for printers." "Another advantage of the ‘sandwich product’ is that it can be printed with various kinds of printing techniques and machines – therefore eliminating costly in-house development work and avoiding investments in new equipment, ...

A group of researchers at the Institute of Microstructure Technology, Light Technology Institute & Thin Film Technology (TFT) at Karlsruhe Institute of Technology has published an RRL Solar article "Correlative In Situ Multichannel Imaging for Large-Area Monitoring of Morphology Formation in Solution-Processed Perovskite Layers" highlighting a novel method for measuring the quality of large-area thin films in a threefold manner: Reflectance, Photoluminescence (PL) intensity and PL emission wavelength in a fast and simultaneous way. "Optical (or IR) techniques have the advantages that they can be easily used for monitoring common solution processing methods such as spin coating or blade coating and that they can provide large-area information at low cost using cameras as imaging detectors, while the necessary large-area excitation can be provided by high-power light-emitting diodes. Luminescence and reflectance imaging on large areas—established already in other PV technologies as silicon, GaAs, CdTe, and CIGS—as well as luminescence microscopy, demonstrated to yield critical information on the perovskite thin-film quality and the performance of devices incorporating these films. However, to the best of our knowledge, there is currently no technique available combining both imaging capability on large areas and rapid real-time operation for analyzing the dynamics of the perovskite formation." "In response, we developed an in situ monitoring technique based on a commerciall...
