Top-emitting white organic light-emitting devices (TEWOLEDs) with 1D metallic–dielectric photonic crystal (1D MDPC) as an anode are investigated. A quasi-periodic 1D MDPC anode allowed for fabrication of multiple-peak TEWOLEDs. A two-peak or three-peak TEWOLED was obtained by simply adjusting the thickness of the dielectric layers in the MDPC. The efficiency of the TEWOLEDs are comparable to the corresponding bottom WOLED ( 11.1 cd A ) , which are 9.9 (two-peak device) and 9.4 cd A (three-peak device), respectively, and the contrast of the TEWOLEDs is about twice as high as the bottom device owing to the low reflection of the anode.
