The future society will be based on "the Metaverse", which is a fusion of the real world and the virtual world, and accordingly, the importance of hyper-realistic displays as a medium of virtual communication is increasing. To realize such immersive AR/VR near-eye displays, the development of high color-purity light emitters is indispensable to expand the color reproduction range of displays.

Direct Optical Patterning
It is important to selectively deposit the nanocrystal arrays onto the desired locations of thin-film devices or integrated (opto)electronic circuitry by using precise material-adapted patterning methods.

Stretchable Optoelectronics
Stretchable optoelectronics represents a key direction for next-generation devices, enabling electronic and photonic systems that can deform without losing functionality. By combining mechanical flexibility with stable optical performance, these systems open pathways toward wearable displays, electronic skin, and human–machine interfaces.

Optoelectronic Neuromorphic Devices
Our group is developing a new optical neuromorphic that processes image data efficiently using light and electrical signals. It uses colloidal semiconducting quantum dots and perovskite nanocrystals as a light-sensing layer, enabling on-chip learning and overcoming limitations of traditional computing.
