Abstract:
An emissive device includes a substrate having a substrate surface; a chiplet adhered to the substrate surface, the chiplet having one or more connection pads; a bottom electrode formed on the substrate surface, one or more organic or inorganic light-emitting layers formed over the bottom electrode, and a top electrode formed over the one or more organic or inorganic light-emitting layers; an electrical conductor including a transition layer formed over only a portion of the chiplet and only a portion of the substrate surface, the transition layer exposing at least one connection pad, the electrical conductor formed in electrical contact with the exposed connection pad and the bottom electrode; and an LED spaced from the chiplet and including a layer of light-emissive material formed over the bottom electrode and a top electrode formed over the light-emissive layer.
