According to foreign media reports, the Korean KAIST research team developed a low-cost production method for the flexible vertical blue thin-film Micro LED. A team led by Professor Lee Keon Jae Lee of the Department of Materials Science and Engineering developed a method for Thousands of blue gallium nitride (GaN) Micro LEDs are fabricated on plastic (thickness<2μm)阵列的一次性转移方法。
The blue GaN f-VLED achieves three times the optical power density (approximately 30 mW/mm2) compared to a lateral Micro LED. In addition, the team was able to reduce the heat generated by the equipment, thereby extending the useful life of the projection equipment by approximately 100,000 hours. .
This blue f-VLED can fit into skin types conformably with wearable devices, and even implanted into the brain. In addition, the research and development team said that the Micro LED can be stably supplied with power via wireless transmission.
Due to its very low power consumption, faster response speed and design flexibility, Micro LED is expected to replace AMOLED displays. However, to expand to larger displays and TVs, this manufacturing technology will need to be able to transmit millions of Red, Blue, and Green Micro LEDs.
Professor Lee pointed out: 'For future Micro LEDs, film transfer, high-efficiency device and interconnect innovations are all essential. We plan to display smart watch-sized full-color LED displays by the end of this year. '
