Abstract
An optoelectronic device including: a first circuit including a substrate having first and second opposite faces, the first circuit having display pixels, each display pixel having, on the side of the first face, a first light-emitting diode having a first active region adapted to emit a first radiation and, extending from the second face, a second light-emitting diode having a second active region adapted to emit a second radiation, the surface area, viewed from a direction orthogonal to the first face, of the first active region being at least twice as big as the surface area, viewed from the direction, of the second active region; and a second circuit bonded to the first circuit on the side of the first light-emitting diode and electrically linked to the first and second light-emitting diodes.
