抄録

In this study, we developed highly efficient pixelated near-infrared organic light-emitting diodes (NIR-OLEDs) featuring self-emission and small form factor, which are expected to expand applications of light sensing. To realize new NIROLEDs in which active-matrix drive is possible by multiple fine pixels, we established a highly efficient NIR-OLED material and top-emitting NIR-OLEDs with fine pixels. Excellent characteristics including pixel pitch of 7.8 μm, peak wavelength of more than 900 nm, and external quantum efficiency of approximately 1% were successfully demonstrated. In addition, we confirmed the feasibility of highly efficient NIR-OLEDs with fine pixels, which is expected to contribute toward miniaturized sensing light sources with low power consumption, and hence improved value.
