Abstract:
1. A first device comprising: a substrate; a plurality of OLEDs disposed on the substrate; wherein each OLED further comprises: wherein each of the plurality of OLEDs is commonly addressable; wherein the plurality of OLEDs comprises a first group and a second group; wherein each of the OLEDs in the first group of the plurality of OLEDs is patterned and electrically connected such that each OLED in the first group is driven at a first current density; wherein each of the OLEDs in the second group of the plurality of OLEDs is patterned and electrically connected such that each OLED in the second group is driven at a second current density that is different from the first current density; wherein at least one of the OLEDs in the first group of the plurality of OLEDs emits light having a first point on the CIE 1976 (L*, u*, v*) color space chromaticity diagram; wherein at least one of the OLEDs in the second group of the plurality of OLEDS emits light having a second point on the CIE 1976 (L*, u*, v*) color space chromaticity diagram; and wherein the difference between the first point and the second point has a duv value that is less than approximately 0.10.
