In this project division, we are engaged in research and development of Flat Panel Displays (FPD’s) and its peripheral technologies. Specifically speaking, FPDs currently working in our laboratory are "Organic light-emitting display" and “Micro-LED display.” We are also challenging aggressively to develop of a quite new display which the industry cannot challenge.

In addition, we are also conducting the research of organic electronics which are important technology to fabricate a large-area and flexible display. We pick up the promising organic materials and research the device structure and fabrication process to realize the display panels. Organic electronics is a fundamental technology which brings the drastic change in cost and function of the next generation display. It is possible for the chemical suppliers and equipment manufacturers to start at the first stage in the collaboration.

To create a display with new principle, wide range of knowledge from material to system is required. We are eager to collaborate with industry in a new aspect gathering the young and flexible wisdom in university.

KOINE Research Platform:Lit Space System

This research platform aims to build a bridge connecting humans and lighting space. We will return to the relationship between natural light and the human living environment, review the concept of lighting environment, and develop a new Human Lighting Space Technology. Regarding the relationship among health, quality of life and lighting illumination, from the building engineering to the neurophysiology, the fundamental theory of interdisciplinary in the humanities and sciences will be constructed, and finally the future lighting space which can activate and improve the living environment of the human being will be achieved.
