GS Alliance develops a graphene QD and silica composite to create efficient white LEDs

Japan-based material developer Green Science Alliance developed a new composite material made from a combination of graphene quantum dots and silica, useful to create white LEDs from blue LEDs (440-470 nm).

The company says that this is the first adoption of such a material for LED applications. The company says the adoption of the QD and Silica offers superior performance to the currently-used phosphor as the QDs do not suffer from light scattering, and the white LED is more efficient. The material is also not expensive as the graphene QDs can be produced on the cheap. GS Alliance believes the new white LED will be cheaper than current white LEDs on the market.

New imaging technique can help pick out the most efficient carbon quantum dots

A new study by researchers from the University of Illinois Urbana-Champaign and the University of Delaware, Baltimore County, in a collaborative project through the Beckman Institute for Advanced Science and Technology at Illinois, used ultrafast nanometric imaging and found good and bad emitters among populations of carbon dots. This observation suggests that by selecting only super-emitters, carbon nanodots can be purified to replace toxic metal quantum dots in many applications, according to the researchers.

“Coming into this study, we did not know if all carbon dots are only mediocre emitters or if some were perfect and others were bad,” said Illinois chemistry professor Martin Gruebele, who led the study. “We knew that if we could show that there are good ones and bad ones, maybe we could eventually find a way to pick the perfect ones out of the mix.”

Quantum Materials Corp announces a $15 million investment to accelerate its QD healthcare development project

US-based Tetrapod Quantum Dots developer Quantum Materials Corp (QMC) announced that is has received a $15 million investment from Pasaca Capital.

QMC develops QDs for several markets, including the display industry, but it is currently focused on the medical market. The company developed the use of quantum dots to verify covid-10 sample origins and track samples through the testing process. The company brands is medical solutions under the QMC HealthID brand, and the Pasaca Capital investment will support an expansion of the medical market.

Samsung Electronics commits to SDC's QD-OLED TV panels

According to industry reports, Samsung Electronics (finally) committed to adopt Samsung Display's QD-OLED TV panels, and plans to release its first QD-OLED TV in 2022.

Samsung Display announced a $10.85 billion investment in QD-OLED TV R&D and production line in 2019, and has started to produce prototypes towards the end of 2020. The company's plan is to start mass production by the end of 2021, in the first line (15,000 monthly substrates). SDC is also planning a second line to follow the first, to arrive at a total of 30,000 monthly 8.5-Gen substrates.

Zhijing Nanotech and TCL introduce pQDs to LCD technology in a pilot projet

Perovskite QD film developer Zhijing Nanotech updated that it recently concluded a successful pilot with TCL to produce 500 75-inch QD-enhanced LCD TVs with Zhijing's PQDF films.

The company reports that the TVs featured a wide color gamut, 147% BT709 - which is higher than most QD TV's on the market, and higher than TCL's original 75M10 TVs. The green Cadmium-free pQD films have excellent optical properties and offer lower cost compared to current QD solutions, according to Zhijing Nanotech.

Samsung announces its 2021 flagship TVs, the Neo QLED

Samsung announced its latest flagship QLED TV model, the Neo QLED TV. The flagship 2021 models will feature mini-LED backlighting with full-array local dimming, AI upscaling and up to 8K resolutions.
