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.
