Information
A Korean research team at KAIST has developed a soft vertical micro LED mass production technology.
A South Korean academic team has developed a soft vertical micro LED technology that can be placed in the brains of animals to control their movements with light.
The Herald Business reported that a research team led by Professor Lee Kin-jae of the Department of Life Sciences at the Korea Advanced Institute of Science and Technology (KAIST) has successfully developed a soft vertical micro LED technology that can be placed in the brains of animals to control their behavior with light.
The research team designed their own vertical LED device for mass production and successfully transferred 2,500 5~80um thin-film LEDs onto a plastic substrate with anisotropic conductive film (ACF) in parallel to form a soft vertical micro LED.
Vertical Micro LEDs have 3 times higher luminous efficiency than horizontal Micro LEDs and solve the heat problem of thin-film LEDs, extending their service life, improving resolution and increasing product reliability.
Optogenetics, the use of light to control brain nerves, has received much attention. The research team's research results can be selected to locally stimulate brain nerve cells, which can help to conduct precise brain analysis, produce high-resolution brain map and control nerve cells.
The team placed a soft micro LED with a luminous intensity of 30mW/mm2 into the brain of rats to stimulate nerve cells from the surface to the deep inner layers of the brain, thereby controlling the movement of the rats. The technology is low-heat, so it does not damage the animal's brain tissue and can be used as an invasive soft electronic system.
Li Jianzai has been working on micro LED technology since 2009 and has applied for more than 20 patents at home and abroad, and has published more than 40 papers in recent years as a corresponding author.
According to Li, the vertical micro LED and transfer packaging technology developed by his research team can be used in smartphones, mobile device displays and wearable lighting products where low power consumption is important, as well as in human brain science research, light therapy, biosensors and many other fields.
