    Abstract: An improved OLED includes an emissive layer disposed between a cathode and an anode where the emissive layer includes a multi-component host material and a phosphorescent emitter material. The host material includes at least a first host compound and a second host compound, where the first host compound is hole-transporting host compound having the general formula wherein R1, R2, R3, R4, R5, and R6 may be the same or different fluorine atom, chlorine atom, a deuterium atom, a cyano group, a trifluoromethyl group, a nitro group, linear or branched alkyl group (C1-C6), cyclo-alkyl group (C5-C10), linear or branched alkoxy group (C1-C6), cyclo-alkoxy group (C5˜C10), substituted or unsubstituted aromatic hydrocarbon group, substituted or unsubstituted aromatic heterocyclic group, substituted or unsubstituted condensed polycyclic aromatic group, r1, r4, r5=0, 1, 2, 3, or 4 r2, r3, r6;=0, 1, 2 or 3 n=0 or 1, and Ar1, Ar2, and Ar3 may be the same or different, substituted or unsubstituted aromatic hydrocarbon group, substituted or unsubstituted aromatic heterocyclic group, substituted or unsubstituted condensed polycyclic aromatic group, deuterium substituted aromatic hydrocarbon group, deuterium substituted aromatic heterocyclic group, or deuterium substituted condensed polycyclic aromatic group.

    Abstract: A first method comprises providing a plurality of organic light emitting devices (OLEDs) on a first substrate. Each of the OLEDs includes a transmissive top electrode. The plurality of OLEDs includes a first portion of OLEDs and a second portion of OLEDs that is different from the first portion. The first method further includes depositing a first capping layer over at least the first portion of the plurality of OLEDs such that the first capping layer is optically coupled to at least the first portion of the plurality of OLEDs. A second capping layer is deposited over at least the second portion of the plurality of OLEDs such that the second capping layer is optically coupled to the second portion of the plurality of OLEDs but not the first portion of the plurality of OLEDs.
