Abstract
An optoelectronic device including a substrate with first and second opposite surfaces; and electrical insulation side elements extending from the first surface to the second surface and defining, within the substrate, first semi-conductive or conductive portions which are electrically insulated from each other. The optoelectronic device also includes, for each first portion a first conductive contact pad on the second surface in contact with the first portion and a set of light-emitting diodes resting on the first surface and electrically connected to the first portion. The optoelectronic device also includes a conductive, at least partially transparent electrode layer covering all the light-emitting diodes; an insulating, at least partially transparent encapsulation layer covering the electrode layer; and at least one second conductive contact pad electrically connected to the electrode layer.
