Multi Functional Diodes

Mult Function Diode

We have developed a Multi Functional Diodes (MFD) which can be used as both the light emitting and receiving devices with a single device structure. MFDs are expected to be applied to the solar cells in the daytime and the lighting for plant factories in the evening.

Near InfraRed OLED

NIR-OLED
We are working on OLED research in the near-infrared region (700nm and above), which is called "optical window" and is expected to be applied to biometrics and food inspection due to its excellent biological transparency.
