제안 방법
- In this paper, we performed analytical and experimental approach to improve the light outcoupling efficiency of conventional bottom-emitting and transparent-type OLED device by use of nanostructured dielectric mirrors (Bragg reflectors). After suitable OLED model was selected, we defined the microcavity structures.
- In this study, we have investigated the preciselycontrolled microcavity structure using SiO2andTiO2 multi-layers between the ITO layer and glass substrate resulting in the increased light extraction at least to the perpendicular direction of the substrate plane. Experimental data in thedevice using the designed microcavity structure was investigated in a close relation with the simulated properties.
- Spectral change of green and blue emission was expected to give the deeper color. The experimental design and characterization as well as the matching with simulated properties were performed for microcavityOLED for actual application.
이론/모형
- In this work, we have modeled and fabricated microcavity-enhanced OLED using the 1-dimensional distributed Bragg reflector model (DBR). Results show that simulated spectrum intensity of microcavity OLED increased more than 30% compared to the conventional OLED, by use of DBR with TiO2 and SiO2.
