Development of Extremely High Efficacy White OLED with over 100 lm/W

Non-radiation mode of OLED device was reduced by optimizing the distance between emissive layers to the metal cathode. Light distribution of OLED and optical properties of a light outcoupling substrate based on high refractive index microstructures were adjusted to achieve the better combination of...

Zusammenfassung:Non-radiation mode of OLED device was reduced by optimizing the distance between emissive layers to the metal cathode. Light distribution of OLED and optical properties of a light outcoupling substrate based on high refractive index microstructures were adjusted to achieve the better combination of the OLED device with the substrate. Those advanced optical design decreased non-radiative evanescent mode and waveguide mode, and realized a white OLED device with quite high light outcoupling efficiency of at least 56 % and outstandingly high efficacy of 133 lm/W at 1,000 cd/m2.
