Abstract
An optoelectronic device including a first integrated circuit that includes:—a substrate, having first and second opposite surfaces; and—groups of sets of light-emitting diodes resting on the first surface. The integrated circuit also includes:—in the substrate, first side elements for electrically insulating portions of the substrate around each set; and—for each group on the second surface, at least one first conductive contact, connected to the first terminal of the group, and one second conductive contact, connected to the second terminal of the group. The device includes a second integrated circuit containing:—third and fourth opposite surfaces; and—third conductive contacts, located on the third surface and electrically connected to the first and second conductive contacts. The first integrated circuit is attached onto the third surface of the second integrated circuit.
