Inkjet printing developer Notion Systems is building a new company headquarters in Schwetzingen, Germany, with a new production plant. The company recently held a groundbreaking ceremony of the new building which will have 3,600 m² of floor space.

Notion Systems is growing at a rate of 20% per year, and these new premises are needed to cope with its increasing number of orders. The company estimates that 18% of its revenue in coming years will be generated from the display industry, for which the company offers machines for inkjet printing of OLEDs, QDs, and more.

LG Display announced that its 65-inch OLED TV panel received Carbon Trust's Carbon Footprint Certification. 

LG says that its OLED TV panel meets the global standard (PAS 2050) on GHG (Greenhouse Gas) emissions throughout the entire product life cycle. 

Samsung Display launched a new web site, called OLED Finder, in which you can choose your phone model to see whether it uses an OLED produced by Samsung Display.

This is a marketing play by SDC, that aims to establish the superiority of Samsung's own OLED panels, over competing panels made by LGD, BOE, Visionox, etc. The website does not include all phones though that use OLED displays - for example it does not include any of Apple's iPhones. 

Review web site Rtings.com has performed an extensive accelerated longevity test for over three months, testing the latest QD-OLED and WOLED TVs.y 

Rtings reports that both QD-OLED displays (Samsung S95B OLED and the Sony A95K) showed signs of image retention, and it seems in general that the QD-OLED displays suffer from worse problems compared to LG's WOLED. Some of Sony's WOLED TVs also showed signs of image retention.

In 2019, following tensions between Japan and Korea, Japan's government decided to restrict some material exports to South Korea, including fluorinated polyimide, resist and high-purity hydrogen fluoride, materials required for OLED production.

The relations between the two countries are warming up now, and a few days ago the Japanese government decided to lift those restrictions, and the sale of these materials to Korean companies are now possible.

Researchers at the University of St Andrews and the University of Cologne developed a polariton-based OLED device that offers angle-independent narrowband emission.

Polariton-Exciton quasiparticles are created when an OLED material is inserted into a high-quality microcavity. The researchers explain that by sandwiching the OLED device between two "mirrors", strong coupling and hybridization of light and matter can occur. This leads to the creation of the polariton particles.
