KAIST Developed Vertical Micro LEDs Applicable to Brain Science

South Korean researchers developed vertical micro LEDs. Micro LEDs have a shorter current path than horizontal thin film LEDs and, as such, emit less heat, have a lower resistance, and can achieve a higher level of optical efficiency. The Korea Advanced Institute of Science & Technology (KAIST) announced that its research team led by professor Lee Kun-jae designed its own equipment for the vertical LEDs and developed the flexible vertical micro LEDs by simultaneously transferring 2,500 thin film LEDs with a thickness of five micrometers to 80 micrometers. The newly developed technology can triple the optical efficiency of LEDs,
