Nissan Chemical Industries acquires Solvay's soluble OLED IP

Solvay logoNissan Chemical Industries logoNissan Chemical Industries announced that it acquired Solvay's OLED IP and expertise. These patents are related to the production of soluble HIL and HTL materials.

Solvay, an international chemical company based in Belgium, had several OLED activities, which it consolidated under Solvay OLED following the acquisition of Plextronics in 2014. Solvay decided to exit the OLED market as it sees further delays in soluble OLED introduction.

Eli Vronksy at Kateeva

During our recent visit to San Francisco, we caught up with Kateeva’s executive team on a break from their presentations on inkjet printing for flexible OLEDs. Chief Product Officer Eli Vronsky gave us an update, as well as an overview of the company’s product strategy.

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.

OLED-A says 2015 was a great year for the OLED industry, gives interesting projections for 2016

The OLED Association posted an interesting article, summarizing 2015 and giving its projection for 2016 and onwards. So first of all, they conclude that 2015 was a great year for the OLED display industry, with shipments up 53% over 2014 to reach almost 275 million units. AMOLED Revenues grew to almost $13 billion - up 40% over 2014.

OLED-A OLED shipments chart (2008-2015e)

The growth was mostly due to Samsung Display's effort to commercialize flexible OLED displays for mobile phones and the expansion of AMOLED customer beyond Samsung Electronics. LG Display also contributed to the OLED display market, and the OLED association estimates the LG sold over 400,000 OLED TVs. They also say that they shipped around 14,000 flexible OLEDs, but they probably mean around 14 million - as that about makes sense for the Apple Watch.

Mitsubishi and Pioneer to start mass producing color-tunable OLEDs made using a wet-coating process

Mitsubishi Chemical Corporation Pioneer Corporation have developed a color-tunable and dimmable OLED lighting panel produced using Mitsubishi's wet-coating process. The companies say that this panel can be produced for less than one-third of the cost of OLEDs made with regular evaporation-based production methods.

Mitsubishi and Pioneer say that these panels will be mass produced in early 2016. They will make three panels, the OLE-P0505 (55x55 mm, active area 40x35 mm), the OLE-P0707 (69x69 mm, active area 54x51 mm) and the OLE-P0909 (92x92 mm, active area 76x76 mm). All three panels are 1.08 mm thick and feature a max luminance of 2,000 cd/m2 and a color temperature of 3000K to 5000K. The panels will be distributed by MC Pioneer OLED Lighting Corporation.

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).

ITRI developed a highly efficient blue OLED emitter based on plasmon-coupled green PHOLED

Taiwan's ITRI research institute developed a long-lasting OLED blue emitter. The researchers used a green phosphorescent emitter with a new double metal structure - that emits a blue light. The so-called Plasmon-Coupled Organic Light Emitting Diode (PCOLED) structure's lasts 27 times as long as a blue fluorescent emitter.

The researchers explain that a regular green phosphorescent emitter always emits a very weak emission. By using the double-metal structure, more plasmons are generated which means a larger blue emission. This is not an up-conversion process - but merely a change in conditions within the green material. This condition was actually discovered by accident.

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.

UBI says solution-based OLED TVs will be cheaper than LCD TVs

Update: originally we posted that the market for solution-based OLEDs will be $395 million in 2020, but the correct UBI is estimate is much higher - $2.4 billion

UBI Research estimates that solution based OLED processes could reduce the price of a 55" OLED TV panel by as much as 43" compared to the currently used WRGB evaporation based process.

UBI further says that solution-based OLEDs will be cheaper to produce than LCD panels. The company estimates that companies will start mass producing solution-based OLED TVs in 2018, and the market of solution-based panels will reach $2.4 billion by 2020.

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.
