Abstract

This paper investigates the internal physical mechanisms of undulated micro-cavity that controls the emission wavelength in organic light-emitting diodes (OLEDs). Finite-difference-time-domain method is applied to a previously manufactured OLED design featuring optical structure on a wavy over-coat layer. The emission spectrum of dipole oscillation is calculated with various amplitudes of undulation and emission angles. In addition, the guided mode of an undulated micro-cavity is analyzed compared with that of a flat micro-cavity.
