Researchers from Kyushu University's Center for Organic Photonics and Electronics Research (OPERA) developed a new TADF emitter molecule that is based on excited-state intramolecular proton transfer (ESIPT).

The researcher says that ESIPT can be used to design completely new TADF materials, which could enable researchers to achieve a high performance and long-lasting emitter structure, as a new material family may expand the molecule design possibilities. TADF from a ESIPT molecule has been reported previously - but the researchers say that this is the first demonstration of highly efficient TADF observed inside and outside of a device.

LG Display launches a new OLED lighting collaboration program, calling out to designers and product makers that look to create new products that utilize OLED lighting. LG will provide its OLED panels as needed, and may also offer financial support. Deadline for application is October 31st, 2017

The program has two categories, with the first one focusing on new products that utilize OLEDs lighting panels - which could be a lighting product or a non-lighting product. Note that LGD is not looking for "general lighting products" (luminaire or fixture) - it is looking for projects such as wearable devices that embed OLED lighting panels, integrated furniture, etc.

Idemitsu Kosan and LG Chem announced a new collaboration agreement that will allow both companies to use each other OLED material-related patents in certain areas.

Idemitsu and LG Chem hope that this collaboration and patent sharing agreement will accelerate the development of new high-performance OLED materials. Through this cooperative arrangement, both companies will strongly support the OLED business of LG Display - but will also offer the outcome of this collaboration to other display companies.

Following LGD's recent demonstration of a 77" flexible and transparent OLED display, the company has now decided (according to Business Korea, anyway) to start producing rollable large-area (55 to 75 inch) OLED TVs in 2020.

LGD will produce these rollable TVs in its upcoming P10 OLED fab in Paju. The P10 is LGD's most ambitious OLED fab - with a price tag of over $8 billion, it is expected to commence production in 2018, although it will take some time before mass production begins. The P10 will exclusively be used to produce OLEDs - both OLED TV panels (9-Gen or 10-Gen substrates, it seems LG did not decide yet) and small/medium flexible OLEDs.

Universal Display recently announced that it is accelerating OVJP R&D, and the company is looking to commercialize this technology with partners. UDC expects it to take a few years before OVJP can really be deployed in production. The company published the video below that shows off the technology and explains the basic principles and advantages.

OVJP stands for Organic Vapor Jet Printing, and the basic idea is to use a gas-stream based process that resembles ink-jet printing but one that uses evaporation OLED materials which outperform soluble ones. In an OVJP process, the OLED materials are evaporated into a carrier gas that delivers them to a jet engine for direct printing of patterned OLED layers. OVJP is intended for large-area OLED displays and can be scaled up to 10-Gen substrates according to UDC.

Sumitomo Chemical acquired CDT back in 2007, and since then the Japanese company has been developing it's P-OLED (polymer-based OLED) materials and technologies. While initially Sumitomo aimed to produce materials for displays, in recent years it has focused mostly on OLED lighting materials and even panel production.

A noted exception was Panasonic's OLED TV development project which used printing technologies and Sumitomo's P-OLED materials. But Panasonic terminated this project in 2013. We speculated that JOLED, which is based on Panasonic's technology (and other technologies as well), uses P-OLED materials in its prototypes, but we were not sure.

Korean news site DDaily posted an interesting article that states that LG Display is looking to replace the fluorescent OLED emitter used in its OLED TVs with a blue TADF emitter.

Following the introduction into LG's OLED TV production process, LG hopes to also use TADF materials in its small and medium OLED production. The report is a bit confusing, but it seems that LGD also aims to use its WOLED display in small and medium display formats - even for VR applications.
