Merck is a global healthcare, life sciences and performance materials company based in Germany, with a history that goes back to 1668. The company designs, develops and manufactures a wide range of specialized materials including high performance OLED materials.

Following Mercks' 2005 acquisition of Covion and the 2008 OLED-T acquisition, Merck is supplying OLED materials to several OLED makers including LGD, Samsung and the Fraunhofer FEP (COMEDD). The company's OLED research program focuses on solution-processable materials.

In 2013, we interviewed Dr. Udo Heider, VP of OLED unit at Merck, who updated us on the company's OLED business and materials. In 2016, Merck constructed a €30 Million OLED materials production plant in Darmstadt as the company sees OLED as one of its future growth drivers. Merck is collaborating with several companies on OLED technologies, including Seiko Epson and Idemitsu Kosan.

The latest Merck OLED news:

Merck reveals the efficiency and lifetime of their red and green soluble phosphorescent emitters

In January 2013, Merck said that the performance gap between soluble and evaporable OLED emitters is closed - at least in the lab. Earlier this month at the OLED World Summit the company revealed the development results of their phosphorescent materials, comparing them to UDC's materials (as published on UDC's website).

Merck's red emitter features an efficiency of 19.1cd/A, a lifetime (L90) of 5,900 hours and the CIE is (0.66, 0.34). UDC's red material features an efficiency of 29 cd/A and a lifetime of 23,000 hours. Merck's green material features an of 76.4cd/A, a lifetime of 5,200 hours, and the CIE is (0.32, 0.63). UDCs green features an efficiency of 85 cd/A and lifetime of 18,000 hours, The CIE is similar (0.31, 0.63).

UBI explains their views of the OLED TV industry, gives bullish OLED market forecasts

During the OLED World Summit, an analyst from UBI gave an interesting presentation, showing the company's view of the current status of the OLED TV industry, and their OLED market forecasts for upcoming years.

So first of all, we have LG and Samsung. LGD has obviously been successful in launching WOLED OLED TVs, and scaling up to mass production has been achieved. LG is also hopeful that solution processing will enable them to produce RGB-structured OLEDs efficiently. LG is collaborating with Merck and Espon on printing technologies.

Merck: Samsung is committed to OLEDs and will return to the OLED TV market by 2017

The Korea Times posted an interesting interview with Brian Daniels, senior VP from Merck's performance materials-advanced technologies division. Brian says that Samsung is committed to OLED panels - and will return to the OLED TV market by 2017.

Merck says that improvement in OLED materials will enable cost reductions which will enable OLED TVs to reach large production volumes in three years.

Merck begins to construct a €30 Million OLED materials production plant in Darmstadt

Merck announced it has began to construct a new €30 Million ($34 million) OLED production plant in Darmstadt, Germany. This plant will produce high-purity OLED materials for display and lighting systems. Production will begin in the 2,000 square-meter building in July 2016.

Merck hopes that the new plant will help it become a leading supplier of OLED materials by 2018, as the company believes that OLED will take a significant share of the display market, and Merck plans to become a total solution provider and not just a material maker. The company is developing soluble OLED materials in collaboration with Seiko Epson.

Merck's OLED chief: I'm sure Samsung will soon start producing OLED TVs

The Korea Times posted an interesting interview with Merck's OLED unit VP, Dr. Udo Heider. Udo is 'pretty confident' that Samsung will soon start producing OLED TVs again.

In the past few weeks we heard several conflicting reports on Samsung's OLED TV program. Some say they will abandon OLEDs completely (and go for QLED TVs instead), while other reports say that Samsung will soon re-enter the OLED TV market. Last year Merck stated that Quantum Dot based TVs, unlike OLEDs, are no game changer.

Merck inaugurates a new OLED Application Center in Korea

Yesterday Merck inaugurated a new OLED Application Center (OAC) in Pyeongtaek, Korea. Merck invested over €7 million in the new center, and it hopes it will enable them to increase customer satisfaction and capture a larger share of the market - by shortening their time to market.

The OAC has a range of equipment for OLED evaporation testing and reliability analysis. In the future, it will introduce advanced processes such as inkjet printing. The OAC resides in the same site as Merck's Chemical Application Centre established in 2011. Merck also operates a technology development center in Taiwan - which also focuses on OLEDs.

Merck and FlexEnable developed a flexible plastic-LCD demonstrator

Merck and FlexEnable (which was spun-off from Plastic Logic just last week to take over all OTFT development) announced a new partnership to develop plastic-based LCD technology. The two companies say that plastic-based LCDs enables conformal (maybe bendable), light and unbreakable LCDs. Those new displays will be based on FlexEnable's OTFT backplanes.

The two companies report that they are in fact already collaborating and have reached an important milestone towards plastic LCDs and have developed a prototype in a very short timeframe. The IPS demonstrate combines the OFTF array with Merck's LC and organic semiconductor materials.

Merck Korea: Quantum Dots, unlike OLEDs, is no game changer

Quantum Dots enhanced LCDs are starting to enter the market, with reports saying that both LG and Samsung will release such TVs in 2015. Michael Grund, the managing director of Merck Korea, however, says that this technology will not have a significant impact on the global TV and display markets - unlike OLED which could be a game changer.

Quantum Dots are used to enhance the color gamut and efficiency of LCD displays. Sony already commercialized quantum-dots TVs and smaller panel display, as the QD-LCDs are far easier to produce compared to OLED TVs.

Taiwan forms an OLED lighting commercialization alliance

The OLED Lighting Commercialization Alliance (OLCA) was formed a few days ago in Taiwan, with an aim to make Taiwan an important OLED lighting player. The alliance will promote OLED technologies and will include members from materials suppliers to product makers.

The OLCA seems to be led by Taiwan's ITRI. Other members include Merck, RiT Display, WiseChip, Corning, Tongtai Machine & Tool and the TLFEA (Taiwan Lighting Fixture Export Association). ITRI says that more than 60 companies have shown interest in collaborating with OLCA members.

The German PrintOLED project successfully concludes

Merck announced that the PrintOLED project successfully concluded. During the project, the partners investigate several technologies (such as gravure, inkjet printing, slot-die coating and others) and were able to demonstrated OLEDs with homogeneously coated active areas of 10 cm2 and 27 cm2 by classic gravure printing and slot die coating (at least two of the layers were processed from solution).

Merck says that printing two organic layers one on top of the other was a major challenge. The partners achieved significant improvements with specific material sequences. They say that they managed to print with speeds of up to 3 m/s semiconducting OLED layers with a homogeneity meeting the quality standards of industrial-scale OLED production. The knowledge was also applied to OPV and sDSC solar cells.
