2)Extended abstracts will be distributed to the people who registered for the LEDIA 2020.

3) LEDIA 2020 will provide presentation certificates to the authors who have registered for LEDIA 2020 by April 7, 2020.

4) All the keynote/invited talks will be cancelled, and their abstracts are not included in the extended abstracts.

5) We will not prevent resubmission your paper to another conference. If you wish to withdraw your paper, please contact us by April 7, 2020.


Light-emitting diodes (LEDs) and laser diodes (LDs) have been attracting much attention for the application to solid-state lighting. In order to meet the rapid increase in the application fields, the discussion opportunities between the device developers and material scientists are required. We are pleased to announce that the 8th Conference on Light-Emitting Devices and Their Industrial Application (LEDIA 2020) will be held at Pacifico Yokohama, Kanagawa, Japan, on April 21 - 23, 2020. LEDIA 2020 provides a platform for scientists and engineers to discuss progress and future trends in the rapidly advancing science and technology of wide bandgap semiconductors for LEDs and their applications. Their applications into visible and ultraviolet LEDs and laser diodes (LDs) are also included in the scope of this meeting. LEDIA 2020 is sponsored by Akasaki Research Center (ARC), Nagoya University.
