Illumination assembly and method of making same

A method of making an illumination assembly, comprising:

• providing a thermally conductive substrate;
• forming a reflective dielectric layer on a major surface of the thermally conductive substrate;
• forming a patterned conductive layer on the reflective dielectric layer;
• providing at least one LED comprising a post;
• and
• attaching the at least one LED to the thermally conductive substrate such that the at least one LED is thermally connected to the thermally conductive substrate through the post and electrically connected to the patterned conductive layer.

A display, comprising;

• an illumination assembly, comprising:
• a thermally conductive substrate;
• a patterned conductive layer proximate a major surface of the thermally conductive substrate;
• a reflective dielectric layer positioned between the patterned conductive layer and the major surface of the thermally conductive substrate, wherein the reflective dielectric layer comprises at least one aperture;
• and
• at least one LED comprising a post that is attached to the major surface of the thermally conductive substrate through the at least one aperture of the reflective dielectric layer, wherein the at least one LED is thermally connected to the thermally conductive substrate through the post and electrically connected to the patterned conductive layer;
• and
• a spatial light modulator optically coupled to the illumination assembly, wherein the spatial light modulator comprises a plurality of controllable elements operable to modulate at least a portion of light from the illumination assembly.
