Semi-transparent, colored organic light-emitting diodes (OLEDs) were demonstrated by comprising a microcavityembeddedstructure that uses an organic layer sandwiched between thin metal layers as the cathode.Without bias, the coloredOLEDs exhibited various colors depending on the metal/organic/metal cathode configuration, by means of internal interferenceeffects under ambient illumination. By varying the thickness of the organic layer, the transmittance and reflectanceof the colored OLEDs could be controlled. The influence of the microcavity cathode on the light-emitting performances ofOLEDs, such as the efficiencies and the electroluminescence spectra, was also studied.
