1. A full-color pixel arrangement for an OLED device, the full-color pixel arrangement comprising:
- a first sub-pixel comprising an emissive region of a first color and having a first optical path length;
a second sub-pixel comprising an emissive region of the first color, the second sub-pixel having a second optical path length different than the first optical path length;
a third sub-pixel comprising an emissive region of a second color;
wherein the full-color pixel arrangement comprises emissive regions of exactly two different colors.
