Sumitomo to start producing high-performance P-OLED materials for OLED TVs in 2012

Update: we have some more information about this upcoming plant, read more here

Sumitomo Chemical have began construction of a PLED material factory in Osaka, Japan. The company says that this plant will start mass-production of high-performance P-OLED materials in 2012. Total investment will be a several billion yen (a billion yen is about $12 million).

Sumitomo 6.5-inch AMOLED prototype

According to the report, these materials will be used for OLED TV production. Interestingly, back in 2009 Sumitomo said that 2012 will be the year when OLED TV finally takes off...

The world's most efficient OLED on plastic developed at the University of Toronto

Researchers from the University of Toronto developed the world's most efficient OLED on plastic, which they say is comparable with the best glass-based OLEDs. They discovered that coating the plastic substrate with a 50-100 nano-meter thick layer of tantalum(V) oxide (Ta2O5), an advanced optical thin-film coating material enabled them to re-construct the high-refractive index property previously limited to heavy metal-doped glass:

The researchers say that to create a high-efficiency OLED you need a high-refractive-index (n <= 1.8) substrate (to enhance the outcoupling of trapped light in the device). Plastic substrates have a low refractive index (n <= 1.6). The researchers say that their method allows for a high-efficiency OLED that does not depend on a high-index substrate. They used a phosphorescent OLED, a high-index Ta2O5 optical coupling layer, electrically conductive gold layer and hole-injection MoO3 layer. All these components are collectively optimized to achieve high efficiency. The maximum external quantum efficiency reaches 63% for green, which remains as high as 60% at >10,000 cd/m–2.

The Galaxy Note's 5.3" HD Super AMOLED display "is as gorgeous as it is enormous"

Engadget posted a review of Samsung's Galaxy Note, and they say that "the 5.3" HD Super AMOLED display is as gorgeous as it is enormous...1280 x 800 pixels in a smartphone display is quite a feat, and it's just as impressive to behold as it sounds. The Note's 5.3-inch Super AMOLED screen is incredibly bright, vibrant and detailed, thanks to its 285ppi resolution... colors on the Note pop just as they do on the GS II, that eye-pleasing contrast and saturation we've come to love from Samsung's AMOLED displays, and little vibrancy is lost when viewed from the side. However, color accuracy does start to wander a bit. This is indeed a PenTile display and so there are more green sub-pixels than any other color. This gives everything an ever-so slightly sickly tinge, especially when viewed off-angle..."

Samsung's Galaxy Note is a large Android v2.3 phone (or mini-tablet?) with a 5.3" Super AMOLED display with an HD resolution: 1280x800. Other specs include a dual-core 1.4Ghz processor, 8mp camera, touch display with pen input (it has a stylus). The phone is 9.65mm thick and weights 178 grams. The note is now shipping in Europe (£592 in the UK, without a contract).

Samsung Electronics to launch flexible OLED based products in 2012, probably start with phones

Samsung Electronics says that it plans to launch products with flexible OLED panels next year, probably starting with mobile phones, then followed by tablets and other portable devices. The company is actually hoping to introduce the products in the "earlier part of 2012".

This was reported before, although up until now Samsung said the plan is to launch flexible OLEDs in 2013 or 2014, so it's good to see they are advancing more quickly than they thought before. Samsung's flexible AMOLEDs will be fabricated on a plastic (Polyimide) substrate and will be able to withstand high temperature (up to 350-400 degrees). The displays can be bendable - but we assume that the first products will use them inside rigid glass cases - so it'll actually be "curved" displays and not flexible ones.

Qube - an OLED installation with over 1400 OSRAM Orbeos panels

Update: it turns out that Kaneka's installation at the Milano art show in April 2011 used 2,500 OLED lighting panels - which makes it the largest OLED lighting insatllation ever, and makes OSRAM's Qube pale in comparison... Thanks for tip Tomoko!

OSRAM unveiled a beautiful new OLED installation at the Qubique Berlin Tempelhof 2011 exhibition, which uses over 1,400 OSRAM round Orbeos panels. It was designed by Labme, OSRAM's new open source OLED lighting design platform.

I think this is the largest OLED lighting installation ever produced, replacing Philip's Living Shapes OLED wall installation which had 1,152 Lumiblade panels. But the amount of panels is still small compared to Mitsubishi's 6-meter OLED GeoGlobe which uses 10,362 PMOLED displays. Anyway, here's a nice photo of the Qube in the making:

Corning's new Lotus Glass is suitable for high-end OLED and LCD displays

Corning launched a new glass called Lotus Glass, which was developed for cutting-edge displays - such as OLEDs and next-gen LCDs (based on LTPS and Oxide-TFTs). Corning explains that the new glass has a high annealing point that delivers the thermal and dimensional stability required by these new high-performance displays. Lotus Glass has already been qualified and is now in production.

Lotus Glass's intrinsic stability means it can withstand the manufacturing thermal cycles better than conventional glass, and so enable tighter design rules needed in advanced backplanes (which are needed for high resolution and fast response time). It's good to see a new glass substrate from Corning, although we're still waiting for Corning's future flexible glass as shown in their "Day made of glass" video released a few months ago (which features future designs made with durable, transparent and even flexible glass displays):

Samsung SCH-W999

The SCH-W999 is the follow-up to Samsung's SCH-W899, and it too sports a clamshell design with dual AMOLED displays (two 3.5" 480x800 panels). Other features include a 1.5Ghz processor and a 5mp camera.

The SCH-W999 will be released in China for China Telecom soon.

Samsung SCH-i929

The SCH-i929 is a China-bound Android smart phone with a 1.5Ghz CPU, 4.5" 480x800 AMOLED display and a 8mp camera.

The SCH-i929 will be released for China Telecom soon.

Idemitsu Kosan opens a new Korean OLED materials manufacturing company

Idemitsu Kosan established a new OLED materials manufacturing company in South Korea today. The new company (called Idemitsu Electronic Materials Korea) will join Idemitsu current OLED production facility in Omaezaki, Shizuoka - and will supply materials to customers in Korea, Japan, Taiwan, Europe and other countries. Idemitsu says they see further expansion in the OLED industryin the coming years.

The new company will start production sometimes in 2012. It will have around 30 employees (5 transfered from Idemitsu Kosan) and will have an initial capital of 30 billion won (about $30 million USD).
