  • Publication number: 20110204337
    Abstract: There is provided an organic light-emitting diode luminaire. The luminaire includes a patterned first electrode, a second electrode, and a light-emitting layer therebetween. The light-emitting layer includes a first plurality of pixels having an emission color that is blue and a second plurality of pixels having an emission color that is yellow, the second plurality of pixels being laterally spaced from the first plurality of pixels. The additive mixing of the emitted colors results in an overall emission of white light.
