| Summary: | 碩士 === 國立臺灣大學 === 光電工程學研究所 === 101 === Due to their various features and merits, flexible OLED displays are becoming more and more important. Yet, the low optical out-coupling efficiency of OLED devices is still an issue. There are some solution like reducing the quench effect, reducing the total internal reflection between substrate and air, and reducing the waveguilde modes…etc. Yet, some of them will change the OLED flexible feature. Recently, page in Nature Photonics provides a method to improve the optical out-coupling efficiency and keeps the OLED flexible feature. Here, we want to investigate their mechanism by simulation.
In this study, we based on their structures, we conducted a series of calculation. Our calculation indicates only a 1.455Xefficiency enhancement, much lower than their 2X enhancement. The discrepancy of the results may be due to improved electrical properties in their device structures, beyond the pure optical effects.
