Photonic Systems

Prof. Reiji Hattori

In this project division, we are engaged in research and development of Flat Panel Displays (FPD’s) as a major pillar industry of Japan. Specifically speaking, FPDs currently working in our laboratory are "Electronic paper" and "Organic light-emitting 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.
