DSCC: the QD materials market to reach $100 million in 2024, will grow to $122 million by 2027

DSCC says that the demand for QD materials in the display industry is growing, and the market will grow to $100 million in 2024. It will continue to grow and reach $122 million in 2027. 

The main application is in LCD displays (color conversion), but materials used in QD-OLED's (by Samsung Display) is growing and accounts for 31% of the market (in the chart above DSCC notes QD-OLEDs as QD-CC). Production of QD-OLED panels is limited (SDC's total capacity is for around 2 million panels per year) but the material usage is large compared to QD-LCDs.

Canon's new perovskite quantum-dot inks are cadmium free, and thanks for Canon's proprietary technologies, the QDs feature protective shell that enables high lifetime and efficiency. Canon's QDs are about 20% more efficient in light converstion compared to standard QDs, and cover 94.4% of the BT.2020 color gamut - higher than regular InP quantum-dot inks (that usually cover around 88% of the same color gamut).

Perovskite-based quantum dots show promise for high brightness emission

Researchers from Northwestern University developed a perovskite quantum-dots based emitter that features high stability, self-healing and very high brightness.

Perovskite QDs can realize single photon emission at room temperature and have excellent optical properties. The research team has developed a unique spray-synthesis method to create these pQDs which greatly increases the contact area of two different solutions, making it possible to grow a uniform protective organic layer on the surface of the quantum dots.

Researchers use coherent spectroscopy to gain insights into perovskite quantum dots

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.

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.
