Nanosys in talks to go public via a SPAC merger, gain a $1 billion valuation

Quantum Dots developer Nanosys is reportedly in talks to go public via a merger with a SPAC company called GigInternational1. If the deal goes through, Nanosys will gain a valuation of around $1 billion USD.

Nanosys has several lines of QD products, including one that is heavy metal free. The company says it has the world's largest quantum dots production capacity, it lists major display makers as customers and it has shipped materials to over 35 million devices to date.

Reports from Korea suggest that the first QD-OLED TV will launch in H1 2022

A new report from Korea says that Samsung Electronics aims to ship its first QD-OLED TV in the first half of 2022. The first TVs will be 55" and 65" in size, and these will be demonstrated in CES 2022 (in January). Later in 2022 the company will also introduce 70-inch QD-OLED TVs.

Samsung Display has already started to produce panel prototypes, and is on track to start mass production in Q3 2021.

UBI Research: Samsung has almost finalized its QNED development

Market Analysts from UBI Research say that following an analysis of 160 patents filed by Samsung Display related to its quantum dot nanorod LED (QNED) technology, it has come to the conclusion that SDC has has completed the development of the QNED display structure.

UBI says that Samsung still needs to find a way to maintain the number of aligned nanorod LEDs within each pixels, though, so the development is not finished yet.

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.

BOE shows a 55-inch 4K emissive QD display prototype at SID Displayweek 2021

China-based BOE shows its latest emissive-QD display (AMQLED) at SID Displayweek 2021:

The 55-inch display offers a 3840x2160 (4K) resolution, a contrast ratio of 1,000,000 : 1 and a wide color gamut (90% BT2020). BOE says that all the functional layers of this display (HIL, HTL, QD and ETL) were ink-jet printed which enable BOE to achieve a material utilization rate of over 90%.

The Fraunhofer IAP sheds light on its QD-related research activities

"People push towards the light, not to see better, but to shine better" - Friedrich Wilhelm Nietzsche (1844 - 1900)

Quantum dots (QDs) represent the latest generation of hybrid inorganic-organic nanomaterials. They form a triad of inorganic nanotechnology, organic semiconductor technology and solution-based processability. The emission properties of inorganic, luminescent nanoparticles depend directly on the particle size. This size quantization effect makes it possible to control the band gap and thus the emission color of semiconductor materials. The target parameters are a high quantum yield of the luminescence as well as high stability and environmental compatibility.

Samsung Display to focus on QD Displays for its future large-area displays

Samsung Electronics reported its financial results for Q1 2021. The company's revenues was 65.4 trillion Won (around $58.7 billion USD). Operating profit increased 4% from the past quarter to $8.4 billion, as Samsung enjoyed strong sales of phones and consumer electronics, which offset slower sales of displays and semiconductors.

Samsung Display says that for large displays, it will "channel all its efforts towards preparing for the mass production of QD displays".

Researchers set out to uncover a process that hinders quantum dots' light emission

A team of researchers, which included scientists from SLAC, Stanford, the University of California, Berkeley and DOE’s Lawrence Berkeley National Laboratory, recently explained a process that interferes with making quantum dots brighter - when attempting to increase the intensity of emitted light, heat is generated instead - reducing the dots’ light-producing efficiency. The results of this new work could have broad implications for developing future quantum and photonics technologies.

In a QLED TV screen, dots absorb blue light and turn it into green or red. At the low energies where TV screens operate, this conversion of light from one color to another is virtually 100% efficient. But at the higher excitation energies required for brighter screens and other technologies, the efficiency drops sharply. Researchers theorized about why this happens, but no one had ever observed it at the atomic scale until now.
