Reality Devices Research Division

  • Reality Display Device Research Group
    Reality Display Research Group has been researched holography technology for ultimate 3D display technology, backplane technology for driving various types of display panels, and reflective/transmittive display technology with EC (Electrochromic)/LC (Liquid Crystal) materials.

    There are many kinds of technology for visualization of 3D objects such as 3D display using binocular vision with glasses and holography with reconstruction of light waves. Holography has been known as the only technology which can provide natural 3D visualization of any objects without limitation. SLM (Spatial Light Modulator) is indispensible for generation of dynamic 3D images with electronic data. The criterion of SLM for wide viewing angle is very small pixel pitch which is less than 1 micron-meter. Light modulator device and backplane for driving light modulator which will be used for the SLMs with such a very small pixel pitch have been researched in our group.

    Display backplane has the role to driving light emitting or light modulating device according to the external electrical signal. TFTs (Thin-Film Transistors) are the major components of display backplane. Metal oxide semiconductor TFTs have been researched for the application of display backplane in our group. Very short channel (less than 1 micron-meter channel length) TFTs for holography applications, flexible TFTs on thin PI/plastic substrate for flexible or stretchable display/electronics, and transparent TFTs for transparent display or transparent sensor arrays. P-type oxide semiconductor TFTs and memory TFTs have been researched for future electronics including transparent electronics.

    EC (Electro-chromic) devices can adjust transmittance of light according to electronic signal. Smart windows and ECM (Electro-chromic Mirror) of cars are the main application of EC devices nowadays. Light shutters for transparent displays can be another application of EC device in near future. Camouflage and extremely small size light modulator will be candidates for the future applications. New materials and device structure applicable to EC device from large area light shutter to extremely small size light modulator have been researched in our group. Flexible thermo-electronic devices, wire-less energy transport device, and flexible sensor devices have been also researched as the application of display technology.

  • Flexible Device Research Group
    The Flexible Devices Research Group is conducting research on core technologies relevant to materials and element technologies, which are important in realizing next-generation flexible displays. In the short term, we are investigating and developing electrode, substrate, encapsulation, and light emitting structures which can be applied and integrated to realize ultrathin flexible lighting surface. In the long term, we are developing element technologies for skintronics.

    In this field mechanical compliance and stretchability of the substrate and the device comprising components strongly matter. As strategic topics of our research group, we are also exploring technologies for display for virtual and augmented reality. In particular, new light emitting structures and backplane technologies are being investigated for realizing high resolution and ultra-thin OLED microdisplay technologies.

    In addition, we provide various support activities such as evaluation of OLED emitting materials, and support for display security of small/mid size companies.
