Abstract
A surface mount emissive element is provided with a top surface and a bottom surface. A first electrical contact is formed exclusively on the top surface, and a second electrical contact is formed exclusively on the top surface. A post extends from the bottom surface. An emissive display is also provided made from surface mount emissive elements and an emissions substrate. The emissions substrate has a top surface with a first plurality of wells formed in the emissions substrate top surface. Each well has a bottom surface, sidewalls, a first electrical interface formed on the bottom surface, and a second electrical interface formed on the bottom surface. The emissions substrate also includes a matrix of column and row conductive traces forming a first plurality of column/row intersections, where each column/row intersection is associated with a corresponding well. A first plurality of emissive elements populates the wells.
