Achieving three-peak white organic light-emitting devices using wavelength-selective mirror electrodes

We report an effective approach based on wavelength-selective mirrors for implementing three-peak white-emitting organic light-emitting devices (OLEDs). Such three-peak white OLEDs have electroluminescence spectra matching better with the transmission spectra of typical color filters and thus give much enhanced color gamut for full-color OLED display applications. The wavelength-selective mirror uses the metal/dielectric stack that is compatible with the OLED fabrication.
