Emissive display with printed light modification structures

A multi-color emissive display fabrication method, the method comprising:

• providing an emissive substrate comprising:
• a top surface, with a plurality of wells formed in the emissions substrate top surface, and a plurality of emissive elements populating the wells, each emissive element having a bottom surface with an electrical interface connected to an electrical contact on a well bottom surface;
• and,
• printing light modifier structures overlying the emissive element bottom surfaces, wherein the light modifier structures comprise a material selected from a group consisting of high refractive index polymer spheres, phosphors, and quantum dots (QDs).

An emissive display comprising:

• an emissions substrate comprising:
• a top surface;
• a plurality of wells formed in the emissions substrate top surface;
• a matrix of column and row conductive traces forming a first plurality of column/row intersections in the substrate, where each column/row intersection is connected to an electrical contact of a corresponding well;
• a plurality of emissive elements populating the wells, each emissive element having a bottom surface, a top surface overlying a well bottom surface, and a post extending from the emissive element bottom surface;
• printed light modifier structures overlying a plurality of the emissive element bottom surfaces.
