Merck introduces new OLED encapsulation materials that the company says offer superior flexibility, higher reliability, and longer lifetime for flexible devices compared to existing solutions. 

Merck says that its new low-temperature ALD silicon materials offer highly improved barrier characteristics - 100 times more effective than current solutions. And they can be deposited in thin layers - 20 times thinner than existing solutions. Merck introduced low-temperature ALD silicon materials in 2022 for automotive OLED, and the company expects that the new materials will be used for the encapsulation of flexible IT OLED displays (laptops, tablets and monitors).

Universal Display Corporation announced that it has acquired Merck's Phosphorescent OLED Emitter Intellectual Property (IP) assets. This portfolio includes over 550 issued and pending patents around 172 patent families with an average lifetime of 10 years, and represents over 15 years of R&D. 

The two companies also entered into a multi-year collaboration agreement, in which the two companies will create advanced PHOLED stacks based on UDC's OLED green and yellow emitters and Merck's transport and host materials.

Merck inaugurated its first OLED production site in China, that has now begun operations, and it joins Merck's China-based production of liquid crystals and photoresist materials.

Merck's local OLED production will give Merck's China-based and Asia-based customers easier and faster access to OLED materials and a stable and more flexible supply chain.

DSCC updated its OLED material market data, and it now sees AMOLED stack material revenues growing at a 18% from 2020 ($1.07 billion) to 2026 ($2.9 billion). If UDC actually manages to release a commercial blue PHOLED, the market could even exceed $3 billion.

The majority of OLED material revenues from from TV applications, but the market share of mobile devices is expected to grow and reach almost 50% by 2026.

Merck announced that it has completed its OLED manufacturing capacity expansion project at its Poseung site in Pyeongtaek, Gyeonggi Province, South Korea. Merck invested around 20 million Euros to install sublimation equipment and an OLED vacuum deposition unit.

Merck began to lay the foundation for R&D, production and the stable supply of OLED materials to Korean panel makers in 2005, as part of its successful strategy of achieving success through domestic research and production. The company continuously interacts with OLED researchers from Korean panel companies so that Korea can continue to lead the OLED industry, and Merck develops materials for OLED TV and flexible, rollable and foldable OLED displays together with its customers.

DSCC updated its AMOLED material market forecast, saying that the market will reach $1.4 billion in 2021 (up 32% from 2020), and grow at a 16% CAGR from 2019 ($927 million) to 2025, to reach $2.18 billion by 2025.

DSCC takes a look into the material cost for LG Display's WOLED TV panels. LGD will likely manage to implement incremental improvements in material utilization and price, which will enable the company to almost halve the material cost of its TV panels- from $88.14 per sqm in 2019 to $47.19 per sqm by 2025.

Towards the end of 2020, Merck announced that it is expanding its OLED material production site in Korea. The company today announced that HTM production commenced at the site.

Merck is already supplying HTM (Hole Transport Materials) to LGD, to be used in large OLED TV production. Merck is now starting to supply HTM materials for LGD's mobile p-OLED displays as well.

Korea-based OLED materials maker Solus Advanced Materials (previously Doosan Solus) announced that the company will start supplying HTL materials for LG Display, for its E3 line in Paju, used to produce OLED TVs.

According to reports from Korea, up until now Merck was LGD's sole HTL supplier (for large-area WOLED production), and Solus will now replace some of the HTL materials previously supplied by Merck. Solus hopes to expand shipments to LGD and supply HTL materials for LGD's other large-area WOLED fabs.

DSCC posted an interesting post with its latest views and forecasts on the OLED material market. The company expects AMOLED stack material sales to grow at a 18% CAGR in the next five years, from $294 million in 2019 to $2.46 billion in 2024. Compared to its previous estimate, DSCC sees higher sales as demand for OLED TVs and OLEDs in the IT market (tablets and notebooks) is increasing.

DSCC also posted an analysis of LGD's new evo OLED material stack. Compared to LGD's "standard" WOLED stack, the evo adds an emitting green layer to improve the brightness by 20%. This of course adds an extra material cost to the panel price.

Last month we reported that Merck is expanding its OLED laboratories in Shanghai. Today Merck released a formal PR and details its latest plans in Asia.

Merck says that it will invest 26 million Euro ($23.6 million USD) to expand its OLED manufacturing capacities at the Pyeongtaek (Korea) and Shanghai sites.
