  • 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: 20210375834
    Abstract: A method for manufacturing an electronic device including the following steps: a) forming a wafer of electronic chips; b) fixing the wafer of electronic chips to a first support made of a stretchable material; c) removing and/or etching the wafer; and d) stretching the first support so as to move the chips away from one another.

  • Patent number: 11164506
    Abstract: A method of controlling an optoelectronic device including display pixels arranged in rows and in columns. The optoelectronic device further includes first electrodes, each connected to the display pixels of at least one row, second electrodes, each connected to the display pixels of at least one column, and a circuit for controlling the first and second electrodes. The method includes, in a first phase, the activation of the display pixels connected to one of the first electrodes and to one of the second electrodes by the following steps, simultaneously carried out: taking one of the first electrodes to a first potential, the other first electrodes being maintained at a second potential smaller than the first potential; and taking one of the second electrodes to a third potential smaller than the second potential, the other second electrodes being maintained at a fourth potential greater than the third potential and smaller than the second potential.

  • 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.
