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.
Japan is the world's leader in production of these materials (about 90% of fluorinated polyimide) which makes it difficult for producers to find alternatives. This is good news for both LG Display and Samsung Display.
