Japan lifts its ban on the sale of several high-purity materials to South Korea

In 2019, following tensions between Japan and Korea, Japan's government decided to restrict some material exports to South Korea, including fluorinated polyimide, resist and high-purity hydrogen fluoride, materials required for OLED production.

The relations between the two countries are warming up now, and a few days ago the Japanese government decided to lift those restrictions, and the sale of these materials to Korean companies are now possible.

Researchers develop efficient and bright polariton-based OLED devices

Researchers at the University of St Andrews and the University of Cologne developed a polariton-based OLED device that offers angle-independent narrowband emission.

Polariton-Exciton quasiparticles are created when an OLED material is inserted into a high-quality microcavity. The researchers explain that by sandwiching the OLED device between two "mirrors", strong coupling and hybridization of light and matter can occur. This leads to the creation of the polariton particles.

Researchers developed a high performance, low-cost HIL material for solution-processed OLEDs

Researchers from Korea's Pusan National University have developed a new low-cost hole injection layer (HIL) material for solution-processed OLEDs, achieving higher efficiency and lifetime compared to the current state-of-the-art.

The new material is solvent-resistant (>99%) and thermally cross-linkable. The researchers used this material to create a solution-procssed red phosphorescent OLED device. The researchers placed the material between the ITO electrode and the HTL material, thus achieving photo-crosslinking of (poly-TPD) as HTL on top of crosslinked HIL.
