NON-COMMON CAPPING LAYER ON AN ORGANIC DEVICE
First Claim
1. An apparatus comprising:
- a plurality of OLEDs, wherein each OLED comprises;
a first electrode;
a second electrode disposed over the first electrode; and
an organic electroluminescent (EL) material disposed between the first and the second electrodes;
a first capping layer, wherein the first capping layer is disposed over the second electrode of at least a 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; and
a second capping layer, wherein the second capping layer is disposed over the second electrode of at least a 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.

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.
