INTRODUCTION
Light-emitting diodes (LEDs) and laser diodes (LDs) havebeen attracting much attention for the application tosolid-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 7th
Conference on Light-Emitting Devices and Their
Industrial Application (LEDIA’19) will be held at Pacifico
Yokohama, Kanagawa, Japan, on April 23 - 25, 2019.
LEDIA’19 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. Theirapplications into visible and ultraviolet LEDs and laser
diodes (LDs) are also included in the scope of thismeeting. LEDIA’19 is sponsored by Akasaki ResearchCenter (ARC), Nagoya University.

SCOPE
LEDIA’19 covers the wide-bandgap semiconductors andLED/LD technologies in the following major topical fields;
Scope1
Scope2
Scope3
Scope4
Scope5
Scope6
Scope7
Scope8
Scope9Light-Emitting Diodes
Laser Diodes
Photodetectors and Solar Cells
Epitaxial Growths
Extended Wavelength Devices
Novel Fabrication Processes

Invited Talks: 25-minute talk + 5-minute discussion.
Contributed Talks: 10-minute talk + 5-minute discussion.

POSTER PRESENTATIONSIn addition to regular oral presentation sessions, poster
presentation session will be planned to stimulate detailed
explanation and discussion. The size of the poster board is
180 cm in a width and 210 cm in a height. We recommend
the authors to use A0 size (84.1 cm in a width, 118.9 cm ina height) paper/cloth to prepare their posters. Necessary
tools for pinning the posters will be provided. The shortpresentation of a few minutes will be planned prior to theposter session.

PAPER AWARD
A few papers will be selected for the “Paper Award” foryoung researchers. Around 10 papers will be nominated forthe award based on the program committee's ratings of theabstracts. The paper award will be judged from theirpresentations and announced at the closing to be held on
the last day. (April 25, Thursday).
