| Abstract: | Abstract— Top‐emitting organic light‐emitting devices (OLEDs) have several technical merits for application in active‐matrix OLED displays. Generally, stronger microcavity effects inherent with top‐emitting OLEDs, however, complicate the optimization of device efficiency and other viewing characteristics, such as color and viewing‐angle characteristics. In this paper, using the rigorous classical electromagnetic model based on oscillating electric dipoles embedded in layered structures, the emission characteristics of top‐emitting OLEDs as a function of device structures will be analyzed. From comprehensive analysis, trends in the dependence of ewmission characteristics on device structures were extracted, and, accordingly, a general methodology for optimizing viewing characteristics of top‐emitting OLEDs for display applications will be suggested. The effectiveness of the analysis and the methodology was confirmed by experimental results. |
