Xi'an Manareco New Materials announced that it intends to invest around $10 million (76.4 million Yuan) in Idemitsu Kosan's China-based Idemitsu Electronic Materials. Following this investment, Manareco's stake at the company will rise to 20%. 

Xi'an Manareco says that Idemitsu plans to move most of its OLED material production to its China-based company. Manareco is a strategic material supplier to Idemitsu, and it hopes to expand its OLED intermediate business. In addition, the company is developing and supplying OLED stack materials (such as EIL, HIL, ETL and more).

Researchers from Korea's KAIST, ETRI, and Dong-A University propose a new stretchable OLED display architecture, based on a 3D form that includes hidden sections that act both as active emitting areas and interconnectors. The idea is that as the OLED display is stretched, these areas pop into place and add to the emitting area of the OLED. The areas are basically hidden pixels that are only used when the display stretches.

To create this OLED device, the researchers attached ultrathin OLED films to a 3D rigid island array structure through quadaxial stretching, enabling precise, deformation-free alignment. The researchers explain that a portion of the ultrathin OLED is concealed by letting it ‘fold in’ between the adjacent islands in the initial, non-stretched condition and gradually surfaces to the top upon stretching. 

The OLED Toolbox offers a wide array of resources, including guides, projections, analyses, content library and profound insights into the OLED industry and market. Never before has it been so easy to gain access to a complete OLED industry resource.

The OLED Toolbox can be beneficial for many use cases: tuning R&D and marketing efforts, training new employees, market intelligence, identifying partners and customers, optimizing budgets and more. 

As the OLED Toolbox is a whole new concept, the video above can help clarify its purpose, explain what it is all about, and provide details the use cases. Contact us now for more information, and to get samples from the Toolbox. 

Researchers from the University of Manchester, University of Cambridge and University of Eastern Finland, led by Dr. Alexander Romanov have developed a new deep-blue Carbene-Metal-Amide (CMA) OLED emitter material with promising operating lifetime.

The emitter is based on a a new CMA complex with a rigid amide donor, benzoguanidine. The researcher say that the new design unlocks bright charge-transfer deep-blue emission with 100% photoluminescence quantum yields. The excited state lifetimes of the new CMA complexes are among the lowest reported to date among all TADF emitters
(down to 213 ns), resulting in remarkably fast radiative rates of up to 4.7 × 10 6 s⁻¹ .
