New low-temperature curing conductive adhesive for OLEDs developed

Engineered Conductive Materials is introducing a new low-temperature curing conductive adhesive DB-1541-LTC, targeted for OLED and OPV panels. ECM says that the DB-1541-LTC can be cured as low as 100°C, but has a dispensing work life greater than 48 hours (measured as a 25% increase in viscosity), while maintaining optimized rheology for dispensing and excellent damp heat resistance and conductivity stability on tin, tin-silver and silver-plated ribbons.

The new adhesive features a rubber-like flexibility - good for flexible applications with high peel strength to withstand the stresses induced in reel-to-reel manufacturing processes.

Sony to buy all of AUO's OLED capacity for its mobile phones?

A few days ago it was reported that AUO is collaborating with Sony on OLED production , and today the Chinese Commercial Times reports that Sony will buy all of AUO's AMOLED production capacity in the near term. Sony will use AUO's 4.3" AMOLED panels in upcoming mobile phones. This contradicts earlier reports that HTC secured AUO's entire capacity.

AUO's original plan was to produce AMOLEDs in Q2 2011, but the company delayed this due to technical issues (apparently the company couldn't get the yields of the vacuum evaporation deposition of the organic layers high enough). It is suggested that Sony's engineers are assisting AUO with those technical issues.

11 arrested in Korea over AMOLED technology leak from Samsung to "local rival"

The Korean police announced today that they are investigating a case of key technology leaking from Samsung Mobile Display to a local rival firm. This technology is Samsung's Small Mask Scanning, used to produce AMOLED on large substrates. The local rival may be LG Display (Samsung's biggest AMOLED competitor) but this is strange as they are using a completely different front plane architecture (WOLED-CF) in their own large panel production and this technology does not require fine patterning.

11 people were arrested in the case - former and current researchers at SMD and employees of the rival firm. The main suspect is a 46 years old former researcher at SMD who now works at the rival company. The police suspects he received 190 million Won (about $168,000) for the secret data. He is also suspect of sharing the information with a Chinese display maker.

Japan Display to start producing OLED panels by March 2013

Japan Display (the new small/medium display maker that merged Sony, Hitachi and Toshiba's businesses) announced that it plans to start mass producing OLED displays for smartphones. First panel samples are expected by March 2013. In order to have an edge over Samsung, JD aims to achieve over 300 ppi and develop panels that are more efficient than Samsung's OLEDs. Analysts suggest that JD will try to secure Apple as a customer for their OLED panels.

Back in November there were reports that JD plans to accelerate OLED mass production with a $1.3 billion investment in OLED R&D (which probably includes pilot production plants), and later on invest a further $1.4 billion towards mass production. It was suggested that JD may convert their Mobara LCD plant (bought from Panasonic) to LTPS and later to AMOLED production.
