Joint research team achieved major breakthroughs in Micro LED technology

Recently, a joint research team jointly established by the Institute of Physical and Chemical Technology of China Academy of Sciences, Jilin University, and the University of Science and Technology of China has achieved remarkable results in the research and development of Micro LED technology. The team successfully developed an innovative technology that used a graphene intermediate layer to achieve remote epitaxial growth of continuous crystalline perovskite films over an area of 4 square centimeters. A major breakthrough in this technology has effectively eliminated grain boundaries and achieved a pure out-of-plane orientation of the crystal.
通过此项技术，团队收获了一系列显著成果：电致发光效率（EQE）高达 16.1%，亮度达到 400000nit，同时实现了像素尺寸仅为 4μ m 的超高分辨率。The research results have built a new technology platform for epitaxial perovskites, which can monolithically integrate bright, efficient and uniform light emission characteristics with LED electronic devices, thus providing a basis for the manufacture of ultra-high pixel size of less than 10 m. Resolution Micro LED display laid a solid foundation.

At present, Micro LED, as the next generation display technology, is emerging in the fields of optical communications, augmented reality and virtual reality, and wearable devices, showing huge development potential. Metal halide perovskites are regarded as an ideal material choice for manufacturing high-brightness LED displays due to their efficient luminescent capabilities, long-range carrier transport properties and scalable manufacturing advantages. The technological innovation of this joint research team has injected new vitality into the further development of Micro LED technology, and is expected to promote greater technological leaps in related fields and play an important role in the future display technology market.
