A multi-color pixel array and method includes an organic active layer of a material emitting a first spectral distribution of visible light having a first color; a transparent conducting layer, each of which include portions that correspond to individual pixels and sub-pixels of the array; one or more pairs of electrodes for selectively energizing sub-pixel areas of the organic active layer to generate an emission of visible light of a first spectral distribution; wherein different sub-pixels within individual pixels of the array have different optical thicknesses based at least on corresponding sub-pixel portions of the transparent conducting layer having different optical thicknesses; and wherein at least one sub-pixel of has a selected color different from the first color due to at least one narrowed spectral band being selected out of the first spectral distribution as emitted light is coupled out of the display through the transparent conducting layer.
