Abstract
An optoelectronic circuit including a substrate and display pixels, each display pixel having a first light-emitting diode adapted to emit a first radiation and a second light-emitting diode adapted to emit a second radiation, the first light-emitting diode having a planar structure and resting on the substrate and the second light-emitting diode having a tridimensional structure and resting on the first light-emitting diode or crossing at least partially through the first light-emitting diode.
