MSI says it will launch an "super ultra wide" QD-OLED monitor in early 2023 (during the CES conference). The company did not disclose much - beyond saying that it will offer a 240Hz refresh rate, and that its current name is Project 491C.

Samsung is the only QD-OLED Panel maker, and it does not offer a 240Hz panel yet (the only monitor-sized QD-OLED is a curved 34-inch 175Hz 3440x1440) - so it seems as if MSI is using a panel that hasn't entered production yet. This will be interesting to watch!

According to a report from Korea, Samsung Display has decided to increase its QD-OLED production capacity, and start making panels for monitors, with sizes of around 27-inch (currently the smallest QD-OLED panel in production is 34-inch). Samsung aims to supply these panels to Apple.

It is said that SDC debated whether to adopt RGB (direct-emission) OLED displays for its future monitor panels, but the lower cost of producing QD-OLED panels led Samsung to this decision. It will continue to produce RGB OLEDs for its tablet and laptop displays.

Developing blue-emitting quantum dots is highly challenging, and researchers from the University of Tokyo says that using a new bottom-up design strategy and self-organizing chemistry they have managed to create a high purity blue-emitting QD material (with a narrow emission spectrum).

The new QDs are made from special chemical composition that combines both organic and inorganic substances, such as lead perovskite, malic acid, and oleylamine. The materials self-aligned into a cube of 64 lead atoms. The lead researcher, Professor Eiichi Nakamura, says that "it took over a year of methodically trying different things to find that malic acid was a key piece of our chemical puzzle".

In the next two weeks, Toray Research Center (TRC) is hosting online webinars focused on display technologies. TRC, who supplies technical analysis and support for R&D and manufacturing, invites you to attend the online lectures at no cost, to learn more about QD, microLED and OLED technologies.

The webinars include recorded presentations, which will be available online up until to November 22. You can register for the webinars here.
