Patent ID: 11751455

Abstract:
An apparatus that includes a plurality of OLEDs provided on a first substrate is disclosed. Each OLED includes a first electrode, a second electrode disposed over the first electrode, and an organic electroluminescent material disposed between the first and the second electrodes. The apparatus also includes a first capping layer that 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. 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, and the second portion of the plurality of OLEDs is different from the first portion of the plurality of OLEDs.
