DuPont is a science-based producer that is involved in many markets including materials, plastics, electronics, energy, medical and transportation. Dupont is a public company that trades on the NYSE (ticker: DD).

Dupont is also involved in displays - and is developing innovative and sustainable solutions that improve display performance, reduce production costs and enable next-generation technologies across a broad range of applications,.

DuPont has been developing OLED materials and process solutions for many years, active in both evaporable and soluble materials. In 2015 DuPont built a state-of-the-art scale-up facility to produce OLED materials. Dupont has also developed a new manufacturing process that use a 'spray-printer' together with Dai Nippon Screen - which may lead the way towards cheap OLED TVs.

In 2019 LG Chem acquired DuPont's soluble OLED technologies and assets (including 540 materials and process patents), in a deal estimated at $175 million.

In February 2015 we posted an interview with David Flattery, DuPont's OLED unit Director of Operations that was kind enough to update us on the company's materials and OLED technologies.

In 2015 Dow Chemical merged with DuPont to create DowDuPont, but after 18 months DowDupont was split into three companies, and Dupont became a public company again.

The latest Dupont OLED news:

P&H signs an OLED material supply agreement with Dupont

According to reports from Korea, P&H Tech signed a long-term contact with Dupont, for the supply of OLED materials. The deal, worth $6 million USD (paid up front), will last until 2028.

It is not clear what kind of materials will P&H Tech supply - whether these will be OLED intermediates or OLED stack materials, as P&H supplies both. The company did say that the materials it will supply to Dupont "can improve the life and luminance of OLED panels".

LG Chem acquires DuPont's soluble OLED IP and technologies

LG Chem has acquired DuPont's soluble OLED technologies and assets, in a deal estimated at $175 million. LG Chem will receive DuPont's entire soluble OLED IP (540 materials and process patents) and all of DuPont's related equipment and R&D facilities. The deal does not include any assets related to Dupont's evaporation OLED business.

LG Chem and DuPont soluble OLED technologies acquisition ceremony

LG Chem believes that the OLED industry is moving towards ink-jet printing of OLED panels based on soluble OLED materials and technologies - and it has now acquired key technologies in this area. DuPont has been developing related materials for over 20 years, has been collaborating with equipment makers (such as Kateeva) and display makers and has also developed its own nozzle-printing process.

CSoT details its OLED ink-jet printing plans, collaborates with Kateeva, Sumitomo, Merck, DuPont and Tianma

Last month CSoT (TCL) announced plans to establish a 11-Gen LCD+OLED TV fab in Shenzhen, China. Details on the OLED part of that fab were not given, but now we have some updates following the company's investor day.

The new fab will use Oxide-TFT backplanes, and it turns out that the OLED part of the fab will also use the 11-Gen substrates (which may be cut for the actual OLED front plane deposition). Out of the entire capacity of 90,000 monthly substrates, the OLED line will use 20,000 substrates. The fab will start mass production in 2021.

ETNews: Samsung to use a full-screen OLED on the GS8 and a new OLED materials recipe

According to a story on ETNews, Samsung aims to use a full-screen display in its next flagship phone, the Galaxy S8. To achieve such a display, Samsung is using a flexible AMOLED that is wrapped around all four sides of the phone (unlike its current edge phones that are cured on two edges only).

SDC M8 vs M7 OLED materials recipe comparison

ETNews also says that SDC is set to update its OLED material recipe. The so-called M7 iteration was used in the Galaxy Note 5, the GS7 and the Note 7. But now Samsung is updating its recipe to M8. You can see the different suppliers in the chart above. Most materials are sourced from the same supplier, but of course the suppliers are offering newer, updated materials and Samsung may switch to those.

UDC's evaporable emitters still outperform the best soluble materials

A few weeks ago we posted about Merck's soluble OLED material performance, and today we have some more data from the OLED Association. In the table below you can see how Merck's, Sumitomo and DuPont's soluble materials compare to UDC's evaporable OLED's materials.

Soluble vs evaporable oled performance (table, OLED-A)

As you can see, for the red material, evaporable OLEDs have a clear lead in lifetime and efficiency. For the green material that efficiency gap has pretty much closed, while the lifetime of the evaporable materials are still about double than the best soluble materials.

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.

UBI OLED TV industry status update (Nov 2015)

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.

DuPont opened a new scale-up soluble OLED material production facility

DuPont announced the opening of a new state-of-the-art, scale-up manufacturing facility designed to deliver production scale quantities of advanced solution-based printed OLED materials. DuPont specifically says that these materials will target OLED TV applications.

The new OLED facility has large-scale formulation systems and can support simultaneous production of multiple product lines. DuPont invested over $20 million in this new facility, which was also funded by a grant from the state of Delaware back in 2012.

Kateeva and DuPont to jointly optimize soluble materials for inkjet printing

Kateeva and DuPont announced that they will co-develop solutions for ink-jet printed OLEDs - specifically they will optimize DuPont's soluble materials for Kateeva's inkjet systems. The two companies hope this collaboration will enable then to offer a simple and highly-effective OLED TV printing process.

This follows Kateeva's agreement with Sumiomo Chemical that aims to pair Sumitomo's PLED materials to Kateeva's YieldJet OLED ink-jet printing platform.

DuPont updates us on their OLED advances, sees printed OLED TVs soon

DuPont has been working on OLED materials and processes for a long time, but it's been a while since we heard any update. David Flattery, DuPont's OLED unit Director of Operations was kind enough to update us on the company's materials and OLED technologies.

Q: Dave - thanks for this interview. We know that DuPont is focusing on soluble OLED materials and processes. When do you see the OLED display industry starting to adopt such materials?

DuPont is focused on developing OLED materials for evaporation and soluble technologies, as well as working with our partners on our proprietary printing process.

Many in the industry believe that 2017 will be the year of mass production for printed OLED televisions, and while we cannot disclose the manufacturing plans for our partners, we have already seen one large manufacturer announce that they will pilot solution- processed OLED displays up to gen-8 in 2015.

DuPont to extend its OLED lighting research collaboration with the Holst Centre

DuPont announced that it is extending its collaboration with the Holst Centre. This collaboration is expected to advance technology in the areas of OLED lighting, wearable electronics, in-mold electronics, sensors and smart packaging.

DuPont says that they hope this collaboration will generate innovation that will be key to unlock new opportunities in this market. The company recently announced advances in nano-silver conductor inks for OLED lighting.
