Nobel Laureate Shuji Nakamura Upbeat about Outlook of Micro-LED, Laser Lighting, LiFi Technologies

In comparison to OLED, Micro LED does not require filters and polarizer while providing better brightness and superior energy efficiency with longer life time. Two fundamental and crucial challenges are confronting Micro LED technology. First, the size of LED chip impacts on external quamtum efficiency (EQE). The ultra-small chip size of Micro LED means tiny current spreading area and extremely high current density. Second, the sourcing technology, as well as picking and transfer technology of Micro LEDs. Laser lighting is being widely used in projectors, micro projectors, laser TV at 100” and above, laser automotive headlights. In comparison to LED headlights with full beam at 300 meters, laser headlights double the distance at 600 meters. In comparison to Wi- Fi, Li- Fi communication that adopts LED or laser technologies have better transmission capacity. Adding wireless communication and hand-held applications to lighting, say applications of smartphones, could open unlimited development. It’s projected that the market value of Li-Fi and visible light communication are to reach $115 billion by 2022. http://www.ledinside.com/
