At CES 2013 Panasonic unveiled a 56" 4K (3840x2160) OLED TV panel prototype that was produced using an all-printing method. Back in January we assumed Panasonic were using SMOLED materials, but now Sumitomo Chemical revealed (as part of their 2013-2015 plan presentation) that this TV prototype used the company's PLED materials.

Panasonic has been working on OLED printing technologies for quite some time and back in 2009, they teamed up with Sumitomo to jointly-develop OLED TVs, based on Sumitomo's PLED materials and technology. I thought this partnership is not active anymore, but evidently I was wrong on that one.

Panasonic unveiled a 56" 4K (3840x2160) OLED TV panel prototype that was produced using an all-printing method. Panasonic calls this the "RGB all-printing method" and they say that all the organic materials were deposited using ink-jet printing. Panasonic says that their OLED panels deliver superb image quality, high contrast and fast response rate. The panels are efficient, ulta-thin and light weight. Panasonic considers OLED as a "promising option for next-generation displays".

Panasonic's panel uses a top-emission structure with a transparent cathode, which results in a more efficient panel (Sony's OLEDs use the same structure, this may be Sony's technology). The panel's TFT substrate was supplied by Sony (so it's probably an Oxide-TFT based panel) as part of the two companies collaboration. Interestingly, even though it seems that they use red, green and blue sub-pixels, Panasonic applied a color filter layer as well - to tune the emission color and achieve high color purity and "superb color reproduction".

Sumitomo Chemical is showing PLED lighting panels at the FPDI 2012 conference. Some of these panels are color tunable, I think it's the first time we see those kinds of panels from Sumitomo:

Back in March 2012 we posted an update on Sumitomo's OLED program. According to the company's roadmap, by 2015 they plan to produce PLEDs on plastic substraces which will feature between 20,000 and 30,000 hours of lifetime and 60-80 lm/W. These plastic based OLEDs will also be flexible.

Sumitomo Chemical has joined the Holst Centre's shared research program on Printed Organic Lighting and Signage. The program's aim is to develop new manufacturing processes that enable low-cost flexible OLEDs. Sumitomo will help the program's investigation of multi-layer solution processes for high-efficiency OLEDs, using the company's PLED materials.

Flexible OLED lighting prototype

Sumitomo will provide other program members access to its OLED materials - especially the emitting materials. Sumitomo will be able to use the program's expertise in order to optimize its own materials for low-cost production and flexible substrates.

Last week we reported that Sumitomo Chemical is planning to start mass producing OLED lighting panels later in 2012 based on their PLED technology in a ¥5-6 billion ($60-70 million) investement. Now Sumitomo finally announced that they plan to unveil panels at the L+B 2012 exhibition, and also unveiled a web page with lot's of info on their PLED lighting program. It seems that the company will commercial PLED panels for "decorative lighting" in 2013, and for general lighting in 2015.

In L+B2012 Sumitomo will show new PLED panels that are about 10 centimeters square each. There will be panels in sixty different colors, which are made using printing technology (all layers except the electrodes). The booth was designed by world-renowned Japanese lighting designer Motoko Ishii, with the theme The Colors of Japan The Colors of Harmony, in an innovative attempt to replicate—by means of lighting—the elegant and refined colors of ancient Japan in a modern day setting of a Japanese traditional tearoom. Here's what the booth will look like:

Update: Here's some official notice from Sumitomo on their PLED lighting plans...

There are reports that Sumitomo Chemical is planning to start mass producing OLED lighting panels. The company will start accepting orders next month, with mass production to begin later this year. Sumitomo will invest ¥5-6 billion ($60-70 million) in equipment.

Sumitomo will probably base their lighting panels on PLED materials. If indeed this report is true we'll probably hear something official soon.

According to new reports, Panasonic started to build a new 8.5-Gen OLED TV pilot production plant in Himeji, Japan. The company has already ordered some of the equipment. Panasonic's Himeji plant is currently producing LCDs (apparently it has a capacity of 810,000 monthly TVs).

Reportedly, the investment in this stage will not be large as this will be a small pilot line - Panasonic currently only wants to do some R&D and testing there. The company still needs to assess the business model. But its clear that the Japanese maker does not want to leave the emerging OLED TV business to its Korean competitors...

A few weeks ago we reported that Sumitomo Chemical began construction of a PLED material factory (which will be operational in 2012) in a several billion yen investment. These materials are aimed towards large panel (OLED TV) production. Today we have a new report that say that Sumitomo made a breakthrough in its PLED material technology - which will eventually enable production cost to be slashed by up to 50% (compared to SM-OLED based displays).

The annual output of their new Osaka plant will be enough to produce 4-5 million 40" OLED TVs. Sumitomo plans to offer these materials to TV makers in Japan, South Korea, and Taiwan. PLEDs (or Polymer-OLEDs, sometimes called PLED too) are OLED devices made from polymer (large-molecules) materials and are more easily adapted for printing (solution-processable) compared to Small-Molecule OLEDS (SM-OLEDs). Some companies believe that PLEDs are the best way to create large OLED panels using printing methods. You can read more about PLEDs here.

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).

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...

OLEDNet reports the Konica-Minolta plans to start mass production of flexible OLED lighting panels in 2010. Konica-Minolta is cooperating with GE on manufacturing technology. According to the report, Konica Minolta is using polymer materials and printing technologies. The materials are made by Sumitomo. The lifetime of Konica-Minolta’s products is estimated to be 3,000 hours or more with the brightness of 1,000 cd/m2.

We think that this is a bit optimistic... according to KM's own plans, the first plant is scheduled for March 2011. Just last month they re-iterated their plans to start making the flexible OLEDs in 2011, and we do not think this will qualify as 'mass production'. We also know that KM is using UDC's Small-Molecule Phosphorescent materials, but maybe they are also working with Sumitomo on Polymer based OLEDs.
