1. A method to improve light extraction efficiencies, the method comprising:
providing a plurality of pixel structures, each pixel structure of the plurality of pixel structures having at least three subpixels; and
providing color conversion films over the plurality of pixel structures to convert light of one or more of the at least three subpixels for each pixel structure of the plurality of pixel structures,
wherein a first of the at least three subpixels has stacked first color conversion layer and second color conversion layer, a second of the at least three subpixels has one of the first color conversion layer or the second color conversion layer, and the third of the at least three subpixels has none of the first color conversion layer or the second color conversion layer.
