Micro LED technology developers from Taiwan unveiled their latest progress in quantum dots (QD) color conversion and wafer production. Lextar introduced its progresses in reliable QD development to realize full color Micro LED displays while PlayNitride shared its achievement of 6-inch Micro LED epitaxial wafers with advanced uniformity. (Image: screenshot from PlayNitride video) Lextar, a vertical integrated LED company based in Taiwan, shared that the company has been working on deploying QD color conversion technology on Micro LED display. Since M...

Micro LED as the innovative display technology is expected to replace TFT-LCD and OLED display in the near future with its high performance including high resolution, high contrast, self-emission, low power consumption and long life. However, the technology still encounter several bottlenecks. The most challenging one for researchers and manufacturers is the notorious mass transfer process which requires bonding RGB LED chips to display backplane accurately and efficiently. The task also needs to tackle the issues caused by different chip materials such as breakable...

Nanoco, a UK-based quantum dot technology specialist, announced that it has filed a patent lawsuit against Samsung, accursing the Korean company of infringing Nanoco’s quantum dot patent.   Nanoco filed the lawsuit in the US District Court for the Eastern District of Texas on February 14, 2020 against defendants including Samsung Electronics, Samsung Display, Samsung Advanced Institute of Technology, Samsung Electronics Co. Ltd., Visual Display and Samsung Electronics America. Samsung was accused of infringing five technologies related to na...

The Fraunhofer Institute for Applied Polymer Research IAP in Germany and Korea Electronics Technology Institute (KETI) announced their cooperation on the development of printed quantum dots (QD) color filters for Micro LED displays. Dr. Youngsam Kim, President of KETI and Prof. Alexander Böker, Head of the Fraunhofer IAP seal the continuation of their cooperation.  Quantum dots are nanocrystals with optical, magnetic or electronic properties. These nanocrystals have a diameter of about 1-10 nm. The small diameter causes so-called qua...

Nanotechnology development company UbiQD announced an optical fiber-coupled luminescent concentrator technology as a new tool for optimizing light in controlled environments, enabling light-guiding to future UbiGro™ spectrum-control greenhouse products. "We continue to push the envelope with light optimization in greenhouses," said Dr. Hunter McDaniel, CEO of UbiQD. "One exciting potential use case is in vertical farming, where you could use our quantum dot-based luminescent fibers to harvest sunlight and optimally transmit that energy to multiple la...

American Cadmium-Free Quantum Dot manufacturer Quantum Materials Corp announced the launching of the Company's new Nano-Materials online store.

Quantum Materials Corp announced that its cadmium-free quantum dots in a remote LED application successfully surpassed the 1000 hour continuous on-time durability test. The testing has been conducted with red and green quantum dots encapsulated in resin and mounted to blue emitting LED's (see diagram below), which are similar to the type of LED's used in standard LCD display back light units (BLU).

Nanoco Group plc, a specialist in the development and manufacture of cadmium-free quantum dots and other nanomaterials, and Japanese OLED startup Kyulux Inc., announced the signing of a collaboration and joint development agreement.

Crystalplex, a pioneer in the development of high stability quantum dots, has announced a new development enabling increased brightness and color stability for LCD displays using cadmium-free Sapphire™ quantum dots.

Contradicting earlier reports in late October about LG giving up on the costly OLED TV technology opting for the less costly quantum dot technology, a latest CNET report noted the company was refocusing on OLED technology and even dedicating a new division to developing OLED screens.

If LCD TVs start getting much more colorful — and energy-efficient — in the next few years, it will probably be thanks to MIT spinout QD Vision, a pioneer of quantum-dot television displays.

Lexington-based QD Vision, Inc., a spinoff of MIT, has developed Quantum LightTM Optic and the lamp is termed a quantum LED (QLED), to produce both lamps and downlighting fixtures that emulate the warm colors of an incandescent bulb but provide much greater light power and lamp life-time. The mechanism behind this extraordinary development is the redistribution of color by means of “quantum dots”. The ability to tune the color of a quantum dot offers a way to redistribute the harsh LED light by placing a specially designed layer of quantum dots in fron...

Japanese Nanoco Group has made great breakthrough on a 1kg batch of green cadmium-free quantum dots for a major Japanese corporation, triggering a US $2 million payment to Nanoco. The green quantum dots were produced at Nanoco's production facility in Runcorn, Cheshire. It marks major technical achievement by Nanoco because green dots are significantly more challenging than red ones due to their smaller size. The Japanese corporation plans to incorporate Nanoco's red and green quantum dots including the backlighting of LCD displays and LED-based general li...
