  • Patent number: 11264427
    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.

  • Publication number: 20210391500
    Abstract: Disclosed is an optoelectronic device including a substrate and at least two sub-pixels, each sub-pixel being adapted to emit a respective first radiation, the substrate, each sub-pixel including: at least one fin made of a first semiconductor material, the fin along a normal direction perpendicular to the substrate, each fin having a first lateral side; and a covering layer including one or several radiation-emitting layer, the covering layer extending on the first lateral side of each fin. The sub-pixels delimit a recess located between both sub-pixels, and a blocking structure being interposed between both sub-pixels in the recess, the blocking structure being adapted to prevent the first radiation emitted by a sub-pixel to reach the other sub-pixel through the blocking structure.

  • Publication number: 20210144824
    Abstract: optoelectronic circuit intended to receive a variable voltage containing an alternation of rising and falling phases. The optoelectronic circuit includes light-emitting diodes and a switching device capable of allowing or of interrupting the flowing of a current through each light-emitting diode. Each light-emitting diode is covered with a photoluminescent layer. The photoluminescent layer covering at least one of the light-emitting diodes includes at least one first luminophore having a first decay constant and at least one second luminophore having a second decay constant different from the first decay constant.

  • Publication number: 20200373461
    Abstract: An emitter adapted to emit a first radiation, said emitter having a substrate, and a mesa made of a first semiconductor material having a first bandgap value. The mesa has a superior side and a lateral side. A covering layer has one or several radiation-emitting layer(s) made of a second semiconductor material having a second bandgap value strictly inferior to the first bandgap value. Each radiation-emitting layer has a first portion corresponding to the superior side and a second portion corresponding to the lateral side. A first thickness is defined for the first portion and a second thickness is defined for the second portion, the second thickness being strictly inferior to the first thickness.

  • Publication number: 20200161285
    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.
