Non-common capping layer on an organic device

摘要

A first method comprises providing a plurality of organic light emitting devices (310-312) (OLEDs) on a first substrate (300). Each of the OLEDs (310-312) includes a transmissive top electrode (322). The plurality of OLEDs includes a first portion of OLEDs (310) and a second portion of OLEDs (311) that is different from the first portion. The first method further includes depositing a first capping layer (302) over at least the first portion of the plurality of OLEDs (310) such that the first capping layer (302) is optically coupled to at the first portion of the plurality of OLEDs (310). A second capping layer (303) is deposited over at the second portion of the plurality of OLEDs (311) such that the second capping layer (303) is optically coupled to the second portion of the plurality of OLEDs (311) but not the first portion of the plurality of OLEDs (310).
