Claim 36:
37. A back emission display comprising:
a transparent substrate with a top surface;
a power interface layer having a bottom surface overlying the substrate top surface, a top surface with a plurality of first electrical contacts and a plurality of second electrical contacts, and a plurality of apertures formed between a top surface and the bottom surface;
an emission layer having a bottom surface overlying the power interface layer top surface comprising a plurality of sub-pixel regions, each sub-pixel region comprising a well overlying a corresponding aperture, a first conductive via electrically connected to a corresponding first electrical contact, and a second conductive via electrically connected to a corresponding second electrical contact;
a back emission micro-light emitting diode (microLED) occupying each well, having an emissive bottom surface overlying a corresponding aperture, a first electrode formed on a microLED top surface, and a second electrode formed on the microLED top surface;
a first electrical interconnect formed on an emission layer top surface electrically connecting each first conductive via to a corresponding microLED first electrode;
an insulating layer overlying the emission layer top surface and comprising a third conductive via electrically connected to a corresponding second conductive via on the emission layer top surface and a fourth conductive via electrically connected to a corresponding microLED second electrode;
a second electrical interconnect formed on an insulating layer top surface electrically connecting each third conductive via to a corresponding fourth conductive via; and,
wherein each first conductive via in the emissive layer is formed as a ring surrounding the well and overlying a corresponding first electrical contact.
