Abstract:
1. A first device comprising: a substrate; a first emissive region and a second emissive region, wherein the first emissive region and the second emissive region comprise a contiguous area, wherein light that is emitted by the first emissive region at normal incidence has a first point on the CIE 1976 (L*, u*, v*) color space chromaticity diagram; wherein light that is emitted by the second emissive region at normal incidence has 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 at least 0.01; a first electrode disposed over the substrate that extends across the first and the second emissive regions; an organic layer disposed over the substrate that extends across the first and second emissive regions, wherein the organic layer comprises the same emissive material across the first and the second emissive regions; and a second electrode disposed over the substrate that extends across the first and second emissive regions, wherein the second electrode includes a patterned layer of conductive material that is disposed in the first emissive region and is not disposed in the second emissive region.
