Laboratory summary

Optical devices, such as televisions and smartphones, play an important role in delivering information, such as images and movies.  Liquid crystal (LC), plasma, electroluminescence (EL), and electrochromic (EC) displays have been developed for display devices.  In these devices, various optical functional materials have been used; however, the mechanism in these materials that controls their optical properties is not clear.

In our laboratory, we develop optical devices related to LC, EL, EC, solar cells, etc.; we also design electronic circuits for optical measurement instruments and driving circuits for devices.

In addition, we are focusing on glow discharge plasma to improve device performance.  Plasma technology is used in various applications, such as microfabrication of integrated circuits and surface modification of materials.  To design high-performance electronic devices, it is essential to understand and control plasma chemistry and physics.  Specifically, we are developing a new plasma generator, and then attempting to achieve sophistication in these electronic devices for application in the fields of water treatment and packaging technology.

Computer systems that analyze such complex phenomena in electronics are also effective in analyzing various business data.  Therefore, we analyze various data by using statistics and machine learning tools (expert system tools, called artificial intelligence: AI), such as Excel and Python (Power BI, Orange, Geographic Information System: GIS).

The research and class subjects of our laboratory are summarized below.  Each research subject is conducted individually.  However, there is also extensive research, such as improving the function of the device with plasma, and analyzing the device optical properties, with a computer.

  1. Research on optical devices (liquid crystal, EL, EC, and aerial image displays)
  2. Research on plasma electronics–plasma technology (plasma generators and plasma applications)
  3. Research on computer systems (geographic information system, electromagnetic simulator, and aerial image display applications)

I hope that you can apply the “fundamentals of electronics” that you have learned in university lectures, seminars, and experiments to research subjects that cover optical device materials, plasma technology, and data analysis.
