Earlier this month UBI estimated that Idemitsu Kosan's OLED material sales grew from around $50 million in 2014 to around $80 million in 2015. Idemitsu's OLED material shipment to LG are probably what's behind this large increase as LG is ramping up its OLED TV panel production

UBI: the OLED emitter material market grew 17% in 2015 as producers increase capacity and change material suppliers

According to UBI Research, the market for OLED emitting materials grew 17% from 2014 to 2015. Universal Display (the top supplier in terms of revenues), Dow Chemical and LG Chem saw a decrease in sales while Novaled, Idemitsu Kosan and Samsung SDI saw improved revenues.

Samsung Display is the largest OLED producer by far, and so when it changes suppliers it changes the whole market. UBI says that in 2015 Idemitsu Kosan, the second supplier in terms of revenue started delivering blue fluorescent emitters to Samsung Display, and also enjoyed the ramp-up in OLED TV production by LGD.

LGD in discussions to acquire Global OLED Technology

According to the Korea Times, LG Display is in talks to acquire Global OLED Technology (GOT), the IP holdings company that owns over 2,000 OLED related patents originally created by Kodak. GOT was formed in 2009 following LG's $100 million purchase of Kodak's OLED business unit.

LG Display already acquired the GOT shares owned by LG Electronics - which gave a value of $156 million to GOT. LGD now owns 65% of GOT, with the rest being owned by Idemitsu Kosan (33%) and LG Chem (2%).

Panasonic to withdraw from the OLED lighting market

Panasonic is reportedly going to withdraw from the OLED lighting market. The Japanese company cannot see earnings coming from this operation due to the high cost of production. Panasonic Idemitsu OLED lighting (PIOL, established in 2011 with Idemitsu Kosan) will be dissolved. Panasonic will turn all of its focus into LED lighting.

This is sad news and a bit of surprise as only a few weeks ago Panasonic demonstrated three new OLED lighting panels at a LED trade show in Tokyo, including the company's first flexible OLEDs. On the other hand, In December 2013 Panasonic also canceled their OLED TV joint development with Sony. So perhaps it makes sense for Panasonic to withdraw from OLEDs altogether.

Global OLED Technology says they prevailed in the Kodak lawsuit, assigned 3 more patents and Pioneer's OLED license

In December 2012, LG's Global OLED Technology (GOT) filed a lawsuit against Eastman Kodak, claiming that 18 of Kodak's patent actually belong to GOT. Kodak said these aren't related to OLEDs and so were not part of the 2009 deal (when GOT bought about 2,200 OLED patents and patent applications from Kodak). GOT also wanted to recover royalty payments from Pioneer that were paid to Kodak and not GOT (he Pioneer license was supposed to have been transferred to GOT but apparently Kodak wasn't able to obtain consent for the transfer).

Today GOT reported that the US court ordered Kodak to assign ownership of 3 patents to GOT (US patents #6,717,560, #6,892,014 and #6,999,138). This was a settlement agreed to by GOT and Kodak. Kodak will also assign the Pioneer license agreement to GOT, including all rights to receive royalty payments from Pioneer under the license.

Panasonic developed a 114 lm/W OLED panel - claims world's most efficient panel

Panasonic Corporation developed a white OLED lighting panel that is the world's highest luminous efficiency - 114 lm/W for a light-emitting area of 1 cm2. Panasonic also developed a larger panel (25 cm2) with 110 lm/W. The panels also feature long lifetime - over 100,000 hours (LT50) and a brightness of of 1,000 cd/m2. The panel thickness was less than 2 mm.

To achieve this high efficiency, Panasonic focused on an all-phosphorescent design (with an optimal stacked layer design) and new light extraction technology. Panasonic used a Built-up Light Extraction Substrate (BLES) by optimizing the arrangement of the film, glass and air to suppress light confinement in the OLED. This enable them to achieve about 2.5 times improvement in the light extraction efficiency, which is about 50% in the new panels. Panasonic says that in older technology the light extraction efficiency stayed below 40%. Panasonic says they hold 30 patents in Japan and 17 overseas - all related for this new development.
