N2 - To create a new sensing light source that is expected to expand its application, we conducted the research and development regarding a self-emissive near-infrared-OLED (NIR-OLED) microdisplay featuring a compact form factor and active drive as a new sensing light source. In order to realize a compact and multi-pixel active-drivable NIR-OLED microdisplay, we have developed a high-efficiency NIR-OLED material and a top-emission-type NIR-OLED device to drive it actively with a CMOS backplane on a silicon substrate. Finally, by integrating this material and device structure, we successfully demonstrated excellent characteristics with a pixel pitch of 7.8 μm, a peak wavelength of more than 900 nm, and external quantum efficiency (EQE) of approximately 1%. Through this study, we confirmed the possibility of realization a high-efficiency NIR-OLED microdisplay with a fine pixel array in principle, and it's expected to contribute to power consumption reduction and miniaturization as a new sensing light source to be apply for new value creation.
