Abstract
An optoelectronic device including a substrate having opposite first and second surfaces; insulation trenches extending through the substrate, surrounding portions of the substrate and electrically insulating the portions from each other, each insulation trench being filled with at least one electrically insulating block and a gaseous volume or being filled with an electrically conductive element electrically isolated from the substrate; at least one light-emitting diode resting on the first surface for each portion of the substrate, the light-emitting diodes comprising wired, conical, or frustoconical semiconductor elements; an electrode layer covering at least one of the light-emitting diodes and a conductive layer overlying the electrode layer around the light-emitting diodes; and a layer encapsulating the light-emitting diodes and covering the entire first surface.
