JOLED announced a partnership with Rosen Aviation, specialists in aviation display technology, to develop and integrate medium-sized OLED displays into aircraft interiors.

Rosen and JOLED already revealed a "first illustration of their capabilities" with a 22" 4K OLED display back in 2019. The companies say that they will launch new OLED displays in a variety of sizes at AIX 2021 (April 2021.

Samsung Display announced that it has commercialized a new foldable OLED display that is the first to achieve a curvature radius of 1.4R mm. This display will be adopted in Samsung's Galaxy Z Fold2 5G (7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED) with an Ultra-Thin Glass (UTG) cover glass.

Samsung says that in order to minimize the folding stress that is increased in such a small folding radius, the company has optimized a series of technologies related to the material of the display, the panel design and the module assembly, so that the multi-layered structure will function like a cushion when the panel is folded.

US-based stable isotopes and compound producer Cambridge Isotope Laboratories announced that it is expanding its deuterated benzene capacity at the company's production plant in Xenia, Ohio.

CIL says its Xenia expansion will increase its deuterated benzene capacity six times. Bromobenzene-d5 is used in the production of OLED displays (among other uses) and CIL reports that it was increased demand for this material which initiated the capacity expansion project and investment.

The US government imposed sanctions against Huawei, which prevents the Chinese company to acquire components that use US-developed chips. According to a report from Korea, both Samsung Display and LG Display will have to stop supplying OLED displays to Huawei as these use drivers that are based on US-developed technology.

Samsung Display has applied for a US US Department of Commerce license which will allow it to export the technology to Huawei. LG Display decided not to apply for the license, at least for now, as its OLED sales to Huawei are limited in any case.

In 2018 Merck opened an OLED technology center in Shanghai, that includes laboratories to enable device fabrication and characterization for local Chinese-based OLED customers.

It is now reported that Merck is investing $26 million to expand the OLED laboratories and build an OLED material plant in the area. The new plant will start production by the end of 2022.

Poland-based Ergis Group has developed a new solution for OLED panel encapsulation. The noDiffusion film, developed in collaboration with Ergis' partners can be adopted as both the flexible substrate and the encapsulation layer for OLED devices.

The Ergis noDiffusion film offers high barrier properties, high level of optical transmittance and a low level of light scattering. This enables the production of OLED displays with extended lifetimes, efficiency and image properties. The noDiffusion film can also be used in the production of solar panels to increase panel efficiency and lifetimes.

Ergis says that the biggest advantage of its new film solution is the lower manufacturing costs, as the films already include an embedded encapsulation layer and could optionally include an embedded electrode layer.

In an interesting report from China, it is claimed that Xiaomi is developing a 27-inch transparent OLED monitor, based on panels supplied by Samsung Display. According to the rpeort Xiaomi plans to release this display by 2021.

Last month Xiaomi announced the world's first "consumer" transparent OLED TV, the Xiaomi Mi TV LUX Transparent Edition that features a 55" 120Hz 120Hz WOLED TV panel. The Mi TV Lux is now shipping in China for 49,999 yuan (around $7,200).

French OLED microdisplay maker MicroOLED announced that it has raised 8 million Euro by EU-based Cipio Partners and Ventech.

Taking place over three half-day sessions on September 30-October 2, 2020, this year's conference will provide the latest developments, key industry insights, and valuable networking opportunities you have come to expect, but with full remote access from the comfort of your home or office.

As the longest running conference dedicated to the lighting and display industry, the OLEDs World Summit is the only place to get a comprehensive view of the current OLED market, innovations for the future, and competing and emergent technologies.

Samsung started to adopt ultra-thin glass covers for its foldable AMOLEDs, instead of polyimide, as it says UTG offers higher durability. In the Galaxy Z Flip, Samsung used a UTG cover produced by Korea-based Dowoo Insys, who processes Schott's ultra thin glass for Samsung Display.

In April 2020 it was reported that Samsung Electronics wants to develop its own UTG cover technology, as as it feels that Samsung Display's UTG is still not robust enough and the company also wants to increase production yields and reduce costs. Now there are new reports from Korea that say that Samsung Electronics is collaborating with Corning in this new UTG project.
