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; a second plurality of pixels having an emission color that is green, the second plurality of pixels being laterally spaced from the first plurality of pixels; and a third plurality of pixels having an emission color that is red, the third plurality of pixels being laterally spaced from the first and second pluralities of pixels.The additive mixing of all the emitted colors results in an overall emission of white light.
