Idemitsu Kosan is a Japanese company, founded in 1911, to engage in oil distribution, and over the years they have gained experience in fuel products and basic chemicals, plastics, electronic materials and OLED materials. Idemitsu is best known for its fluorescent blue emitter and host.

Idemitsu Kosan are working towards OLED materials together with BOE Display, Merck, Sony, LG Display, Mitsui chemicals, Doosan and UDC. Together with Panasonic, the company launched an OLED lighting joint-venture called Panasonic Idemitsu OLED Lighting (PIOL), but PIOL was dissolved when Panasonic withdrew from the OLED lighting market.

In January 2016 we posted an interview with Idemitsu's electronic materials chief.

The latest Idemitsu Kosan OLED news:

Samsung Display developed a 18.2" 350 nits ink-jet printed OLED panel

Samsung Display has developed a 18.2" 2560x1440 202 PPI inkjet-printed OLED display, that features the highest current efficiency of any inkjet-printed OLED, with the brightness at 350 cd/m2 (full white).

Samsung Display says that the high brightness was achieved by tuning the top-emission device structure with high performance soluble materials. The high pixel resolution was achieved by modulating the jetting waveform for ejecting ink drops and improving the drop placement accuracy by selecting the right ink formulations in terms of viscosities and surface energies.

DSCC - OLED material sales will grow from $951 million in 2019 to $2.69 billion in 2024

DSCC updated its OLED material market estimates, saying that AMOLED stack material sales will grow from $951 million in 2019 to $2.69 billion in 2024 - a CAGR of 23%. These new estimates take into account DSCC's reduced input area forecast due to the slowdown in demand cased by the Covid-19 pandemic.

AMOLED material revenues (2019-2024, DSCC)

DSCC says that incremental improvements in material utilization and price reductions, material costs per square meters will decline in the future. The unyielded cost of producing a square meter of a WOLED TV panel will decline from $95.21 in 2019 to $56.11 in 2024.

Idemitsu Kosan and Toray developed a red TADF/HF device that is the world's most efficient OLED emitter

Idemitsu Kosan and Toray Industries announced that the companies have jointly developed a red OLED device that is the world's most efficient emitter at 46 cd/A. The device uses a TADF emitter combined with red fluorescent materials (which likely means this is a HyperFluorescence device).

Idemitsu and Toray has been collaborating on OLED material development since 2017. This new device uses Idemitsu's TADF material combined with Toray's new red fluorescent material. The two companies say that this new material provides the same results as currently used red phosphorescent devices, and the plan is now to "drive forward to secure adoption of their materials" in mobile and TV applications.

Things we learned at the first day of OLED Korea 2019

The first day of the OLED Korea 2019 conference is almost over - with some interesting lectures and talks by leading OLED companies and professionals. Here are some of the things under discussion today (highlights only):

LGD's future plans for OLED TVs at OLED Korea 2019 photo

  • Some believe there will be a real market for >$2,000 foldable OLED devices, and some call for cost reductions before real adoption could take place
  • LG Display is optimistic regarding the future of OLED TVs
  • Samsung will not commit yet to its QD-OLED technology
  • Both Cynora and Kyulux are rapidly progressing towards a long lasting TADF/HF blue - but it seems there's still work to be done
  • Idemitsu Kosan is increasing its fluorescent OLED emitter efficiency
  • Universal Display's RGBB architecture is back on the table - and the company now highlights the architecture's low blue light emission. UDC seems more optimistic then ever regarding blue PHOLED commercialization
  • Equipment maker's focus is shifting to China as Korean OLED makers will not increase capacity in the near future

Idemitsu Kosan starts to construct its OLED materials production plant in Chengdu, China

In April 2018 OLED materials producer Idemitsu Kosan announced plans to establish a new OLED production subsidiary in Chengdu, China. The investment in Idemitsu's third OLED production plant will total $12.8 million USD.

Idemitsu now updates that it is starting to construct the new production plant, which will have a capacity of 12 tonnes per year. The construction will be completed by November 2019 and commercial production is scheduled to begin in the first quarter of 2020.

DSCC lowers its OLED material revenue forecasts, published Samsung's latest OLED stack

DSCC lowered its OLED material revenue forecasts, saying that the market is expected to grow at a 25% CAGR from $773 million in 2017 to $2.35 billion in 2022 (down from its previous estimates of $2.56 billion in 2022). The fastest growing (51% CAGR) OLED application will be OLED lighting, which will grow from $12 million in 2017 to $95 million in 2022.

DSCC also published the material stack for Samsung's latest OLEDs (used in the Galaxy S9), which you can see above.

Idemitsu Kosan to establish its 3rd OLED material plant in Chengdu, China

OLED materials producer Idemitsu Kosan established a new OLED production subsidiary in Chengdu, Sichuan Province, China. The new company, 100% owned by Idemitsu Kosan, is called Idemitsu Electronic Materials (China) Co., Ltd. and the capital investment in this new company is $12.8 million USD.

The new Chengdu fab will be Idemitsu's third OLED production fab, joining its plant in Omaezaki, Shizuoka Prefecture, Japan and Paju, South Korea. Idemitsu says that this new production plant will enable it to meet the growth in demand from OLED makers in China.

Idemitsu Kosan and Toray to co-develop OLED materials

Japan-based OLED material maker Idemitsu Kosan announced a new partnership with Toray Industries to co-develop OLED materials.

Toray and Idemitsu will mutually utilize the OLED materials, technology and expertise that both companies possess, and will cooperate in the development of new materials and material evaluation. The two companies will also jointly use their evaluation facilities and production facilities. Both companies hope that this collaboration will accelerate OLED material development and enable lower cost production.

Idemitsu Kosan and LG Chem to share OLED material patents

Idemitsu Kosan and LG Chem announced a new collaboration agreement that will allow both companies to use each other OLED material-related patents in certain areas.

Idemitsu and LG Chem hope that this collaboration and patent sharing agreement will accelerate the development of new high-performance OLED materials. Through this cooperative arrangement, both companies will strongly support the OLED business of LG Display - but will also offer the outcome of this collaboration to other display companies.

Idemitsu Kosan to expand its OLED material production capacity next year by 70%

According to the Nikkei Asian Review, Japan-based OLED material maker Idemitsu Kosan plans to expand its production of OLED materials by 70% by March 2019 (end of Fiscal Year 2018). Its Korean subsidiary Idemitsu Electronic Materials Korea will increase annual production by 60% to 8 tons (this was already announced last year) while it's Shizuoka plant will double its capacity to 4 tons.
