A research team at Seoul National University (SNU) successfully grew a Micro LED array on a 100 nm-thick sapphire nano-membrane. The results were published on Scientific Reports on May 5, 2020. According to the published paper, the team, led by Euijoon Yoon of the Department of Materials Science and Engineering of SNU, designed the sapphire nano-membrane array to grow an array of multi-faced Micro LEDs sized 4 μm × 16 μm. With the method, the Micro LED chip singulation does not need to go through plasma etching process, leading to a better ext...

Micro LED as the innovative display technology is expected to replace TFT-LCD and OLED display in the near future with its high performance including high resolution, high contrast, self-emission, low power consumption and long life. However, the technology still encounter several bottlenecks. The most challenging one for researchers and manufacturers is the notorious mass transfer process which requires bonding RGB LED chips to display backplane accurately and efficiently. The task also needs to tackle the issues caused by different chip materials such as breakable...

Researchers from Taiwan’s National Chiao Tung University, China’s Xiamen University and SIJ Technology have developed a monolithic Micro LED which achieves full-color display. The study demonstrates that Micro LED full-color display can be realized without mass transferring and the result was published on Scientific Reports and Photonics Research. The team fabricated the Micro LED full-color display on monolithic epitaxial wafer by combining nanoring (NR) structure and atomic layer deposition. From previous study, the researchers have demonstr...
