Abstract: Embodiments of a local optic using quantum dots are described. A local optic includes an optical source on a substrate, a housing, and a film that includes quantum dots. The housing is designed to fit around the optical source and has a cross-sectional area along a plane parallel to a surface of the substrate. The film is designed to sit on top of the housing and has a substantially similar cross-sectional area to the cross-sectional area of the housing.
