Perovskite-Info is proud to announce an update to our Perovskite for the Display Industry Market Report. This market report, brought to you by the world's leading perovskite and OLED industry experts, is a comprehensive guide to next-generation perovskite-based solutions for the display industry that enable efficient, low cost and high-quality display devices. The report is now updated to October 2021.

Reading this report, you'll learn all about:

• Perovskite materials and their properties
• Perovskite applications in the display industry
• Perovskite QDs for color conversion
• Prominent perovskite display related research activities

The report also provides a list of perovskite display companies, datasheets and brochures of pQD film solutions, an introduction to perovskite materials and processes, an introduction to emerging display technologies and more.

Last year, Poland-based Ergis Group launched an OLED encapsulation film platform called Ergis noDiffusion®. The company is currently testing its film solutions at customer sites in Asia, the EU and the US, and it is now starting to offer the same platform for the protection of quantum dot films, including perovskite-based QDs for use in display and lighting applications.

These new films can be tuned to fit specific needs. Ergis can deploy its films on several substrate types, with varying film thickness, and the barrier properties can be tuned to be between 10-6 to 10-3. This means that custom films can be created to suit the specific sensitivity of the pQDs for water vapor and to achieve specific product lifetime or other required properties.

Researchers from National Taiwan Normal University and Kyushu University have developed a new memory device, readable through both electrical and optical methods, that needs only perovskites to simultaneously store and visually transmit data.

By integrating a light-emitting electrochemical cell with a resistive random-access memory that are both based on perovskite, the team achieved parallel and synchronous reading of data both electrically and optically in a 'light-emitting memory.'

A joint research team, affiliated with Korea's UNIST, has developed a novel method capable of controlling the brightness and wavelength of quantum dots (QDs). The work was led by Professor Kyoung-Duck Park in the Department of Physics at UNIST, in collaboration with Professor Sohee Jeong in the Department of Energy Science from Sungkyunkwan University (SKKU).

The research team demonstrated the tip-induced dynamic control of strain, bandgap, and quantum yield of single CsPbBr_xI_3'x pQDs by using a controllable plasmonic nanocavity combined with tip-enhanced photoluminescence (TEPL) spectroscopy.

The U.S. Defense Advanced Research Projects Agency (DARPA) is currently seeking research proposals for the development of x-ray technology capable of what the agency calls "extreme photo imaging."

As part of its Extreme Photon Imaging Capability - Hard X-Ray (EPIC-HXR) project, DARPA said it is looking to develop uncooled hard x-ray imagers based on advanced nanocrystalline materials with high spatial and energy resolution, including quantum dot and perovskite materials.

Researchers at McGill University have gained new insight into the inner workings of perovskites, especially their ability to function even despite the existence of defects in the materials' crystal structure.

"Historically, people have been using bulk semiconductors that are perfect crystals. And now, all of a sudden, this imperfect, soft crystal starts to work for semiconductor applications, from photovoltaics to LEDs," explains senior author Patanjali Kambhampati, an associate professor in the Department of Chemistry at McGill. "That's the starting point for our research: how can something that's defective work in a perfect way?"

Perovskite quantum dots have great potential as quantum emitters, but their inherent instability has thus far hampered their acceptance. Professor Hao-Wu Lin of the Department of Materials Science and Engineering, Associate Professor Chih-Sung Chuu of the Department of Physics, and Professor Richard Schaller of the Department of Chemistry at Northwestern University in the United States have jointly developed a perovskite quantum emitter with high stability and self-healing ability by a self-developed, simple, and economical procedure'spray-synthesis method. The unprecedented single-photon brightness of these quantum dots is said to break the world-record.

Lin said that in contrast with other quantum emitters, perovskite quantum dots can realize single photon emission at room temperature and have excellent optical properties, such as high quantum yield and high color purity, making them ideal for displays and high-speed computing and communications.

Scientists at the Chemistry and Physics Institutes of the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, in collaboration with scientists at the University of Michigan in the United States, have provides insights into the fundamental physics of perovskite quantum dots.

"We used coherent spectroscopy, which enabled us to analyze separately the behavior of the electrons in each nanomaterial in an ensemble of tens of billions of nanomaterials. The study is groundbreaking insofar as it combines a relatively new class of nanomaterials - perovskite - with an entirely novel detection technique," Lázaro Padilha Junior, principal investigator for the project on the Brazilian side, explained.
