    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.

    Abstract: A mixture containing three different compounds that is useful as a stable co-evaporation source material for a vacuum deposition tool is disclosed. The mixture comprises a first compound; a second compound; and a third compound that are all organic compounds and have different chemical structures from each other and each has an evaporation temperature T1, T2, and T3, respectively, in the range of 150 to 350° C. T1, T2, and T3 differ from each other by less than 20° C. The first compound has a concentration C1 in the first mixture and a concentration C2 in a film deposited by evaporating the first mixture in a high vacuum deposition tool under a predefined deposition condition where |(C1-C2)/C1| is less than 5%.
