A device comprising:
- a layer having a light emissive area and a light non-emissive area;
- and
- a light-extracting feature disposed over the light non-emissive area;
- wherein the light-extracting feature comprises surface aberrations disposed over the light non-emissive area in the layer.
1 more element
A method comprising:
- providing a layer that supports a plurality of light-emitting elements, wherein the plurality of light-emitting elements are disposed at a pre-determined distance from each other;
- resulting in the formation of a plurality of light emissive areas, corresponding to the plurality of light-emitting elements on the layer and formation of a plurality of light non-emissive areas, corresponding to the pre-determined distance between the light-emitting elements in the layer;
- and
- disposing a light extracting feature so as to correspond with the plurality of light non-emissive areas on the layer;
- wherein the disposing a light-extracting feature comprises disposing surface aberrations over the plurality of non-emissive areas in the layer.
