Vacuum evaporation - Page 3

According to a report from Korea, LG Display acquired an OLED CVD deposition system from Korea's Sunic System. The new Gen-6 system will be deployed at LGD's upcoming E5 flexible OLED fab in Gumi.

Interestingly, the Korean report says that LGD's first choice for OLED deposition system was Cannon-Tokki, but the Japanese company could not supply the system in time as it has a "rush of orders" from Samsung Display. LGD is hurrying to build the new fab as they aim to start production in the first half of 2017.

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.

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.

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).

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.

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.

Applied Materials announced two new PECVD based deposition systems aimed towards the flexible OLED thin-film encapsulation market.

The two new systems are the AKT-20K (925x1500 mm substrates) and the AKT-40K (1250x2200 mm substrates). Both systems offer the ability to deposit diffusion barrier films with very low water and oxygen penetration. These high-performance films are deposited at low temperatures of

A few days ago LG Electronics launched the beautiful G Watch R smartwatch, with its 1.3" (320x320) flexible plastic-based OLED panel. Today LG Display announced that it started mass producing those OLED panels.

While it was pretty clear that LGD is behind this flexible OLED, it's good to hear a formal confirmation. LG Display further tells us that the panel is less than 0.6 mm thick and features a 100% color gamut (not sure which standard is that), 300 nit peak luminance and of course an "unlimited" contrast ratio.

Last month Japan Display, Sony and Panasonic announced the formation of a new OLED company. JOLED, funded by the Innovation Network Corporation of Japan, will be established formally in January 2015, and will focus mainly on medium sized OLEDs for tablet applications.

JDI 5.2-inch FHD OLED prototype

One of the key questions surrounding JOLED is the technology choice. While Sony (and JDI, which is basing its OLED program on Sony's tech) is using small-molecule OLEDs and an evaporation process, Panasonic based its OLED development on Sumitomo's PLED materials and printing technologies.

Philips' OLED lighting division has a new head of Marketing and Business Development - Jay Kim. Before he was responsible for OLED product marketing, business development, MarCom and customer services functions globally, Jay headed Philips' industry segment marketing in Europe involving Philips LED luminaries, lighting controls and services. And he was kind enough to agree to this interview here at OLED-Info.

Q: Jay - thanks for your time. Let's jump, shall we? In March 2014 Philips announced the FL300, your brightest OLED yet at 300 lumens. Any updates on this panel? Is it still on track for Q3?

We are very happy with the performance of the new Brite FL300 and its acceptance in the market. Already before official market introduction at Light+Building we have had three designs where the brightest OLED on the market is used. Italian furniture maker Riva1920 uses our OLED in its K BLADE lamp, an exceptional beautiful wooden desk lamp combining 48,000 years old Kauri wood from New Zealand with the world’s most modern lighting technology OLED. Besides that, German Designer Thomas Emde is using the Brite FL300 in its new series of OLED luminaires sold under the label OMLED. In addition, he is working closely together with Italian luminaire manufacturer Luceplan. Together they bring the OLALAL OLED luminaire to the market. Also, many of our customers with designs based on the Lumiblade GL350 OLED are going to switch to the new OLED as well.

The Centre for Process Innovation (CPI) is a UK based R&D institute that helps companies develop and scale manufacturing processes. The CPI sent us the following video and update on its OLED/OPV prototype line (built by MBraun) that was designed to enable materials companies, device designers and end users to develop their technology within a fully automated, controlled environment.

CPI's system supports both small evaporized and soluble OLED materials. The line uses slot die technology to allow the coating of substrates in a highly repeatable and reproducible manner with a uniform film thickness of under 50 nm.
