摘　　要：Considerable progress has been made in organic light-emitting diodes(OLEDs)to achieve high external quantum efficiency,among which dipole orientation has a remarkable effect.In most cases,the radiation of the dipoles in OLEDs is theoretically predicted with only one orientation parameter to match with corresponding experiments.Here,we develop a new theory with three orientation parameters to fully describe the relationship between dipole orientation and power density.Furthermore,we design an optimal test structure for measuring all three orientation parameters.All three orientation parameters could be retrieved from non-polarized spectra.Our theory provides a universal plot of dipole orientations in OLEDs,paving the way for designing more complicated OLED devices.
