Kyulux is led by a former Samsung executive; Its staff included engineers with experience both in South Korean display manufacturing companies and in Japanese companies that specialize in materials development. The startup aims to bring its technology to market by leveraging the expertise of specialists from both countries and extensive industry connections. The company’s organic light-emitting diode (OLED) material is called “Hyperfluorescence”, combining two technologies that provide high color purity and luminous efficiency – the latter meaning reduced energy consumption. No precious metals are required to produce this material.
Modern OLED materials often use phosphorescent compounds containing iridium – this rare metal has corrosion resistance and other unique properties; It is widely used in various industries from microchip manufacturing and electronics to aerospace. More than 80% of the world’s reserves are mined in South Africa, which poses risks to the stability of supply – eliminating iridium will help reduce material costs and improve supply chain reliability.
Kyulux continues to seek funding to bring the new material to market. To date, the company has attracted 8.5 billion yen ($53.8 million) in investments. Investors include LG, Samsung and SMBC Capital Partners. The company has also entered into a joint development agreement with LG Display – the parties are working on product evaluation and implementing other initiatives. Of the three primary OLED colors—red, green, and blue—the company plans to introduce its materials into green and red, with its technology expected to appear in final products around 2029. Among Kyulux’s partners is also the Japanese chemical manufacturer Nippon Soda; the company has now accelerated the creation of its own production base.
