Yonsei Professor Selected for Project to Develop Next-Generation Meta-Emitting Display Materials

Yonsei University professor Ahn Nam-young has been selected to lead a new research project aimed at creating light sources for highly immersive displays and next-generation extended reality.

The project, supported by South Korea's Ministry of Science and ICT and the National Research Foundation of Korea, will develop electrically driven meta-emitting materials. These materials are designed to generate light while directing it into a narrow angle, addressing a limitation of conventional light-emitting materials and devices, which spread light broadly.

The research team will combine light-producing materials with optical structures that control the direction of emission. It plans to design and synthesize a multi-exciton, multiphoton-emission material that can maintain efficiency at high brightness. Ultrafast spectroscopy will be used to examine quantum efficiency, optical gain and coherence, as well as the causes of emission losses at high brightness.

The team also plans to use optical simulations, quantum-mechanical modeling and nanoscale control of position and arrangement. Its ultimate goal is to create an electrically driven device that can serve as a practical display light source.

The project targets high efficiency in red, green and blue light, a divergence angle of about five degrees and brightness above 1 million candelas per square meter.
