摘要： An optoelectronic device includes a number of pixels, with each pixel including a lighting mechanism having at least one light-emitting diode capable of emitting an initial light beam, a light-conversion module having a plurality of conversion pads including at least one primary conversion pad and at least one secondary conversion pad. Each pixel includes a light-adjustment system configured to control at least one element chosen from a relative position between the lighting mechanism and the light-conversion module and the initial light beam. The action of the light-adjustment system is adapted so that the primary conversion pad and the secondary conversion pad emit a first light beam and a second light beam respectively, from the initial light beam, simultaneously or alternately in a predetermined sequence.

摘要： An optoelectronic device includes first and second light-emitting diodes, each LED having: a first semiconductor portion, with a first type of doping, having a wire-like shape along an axis and having side surfaces parallel to this axis; an active portion arranged at least partially on a top end of the first portion; and a second semiconductor portion, with a second type of doping, arranged at least partially on all or part of the active portion. The optoelectronic device further includes an electrically resistive layer having an electrical resistance that is higher than that of the active portion, covering at least all or part of the side surfaces of the first portion and all or part of the surface of the top end of the first portion not covered by the active portion. The resistive layers of the first and second LEDs are separated from one another.

摘要： An optoelectronic device including an array of axial light-emitting diodes. The light-emitting diodes each include an active area configured to emit an electromagnetic radiation having an emission spectrum including a maximum at a first wavelength. The array forms a photonic crystal configured to be able to form three resonance peaks amplifying the intensity of said electromagnetic radiation at at least second, third, and fourth wavelengths.

摘要： A display pixel including at least one light-emitting diode, a circuit for driving the light-emitting diode, and first, second, third, and fourth conductive pads. The driver circuit is powered with a first power supply voltage received between the first and second pads. The light-emitting diode is powered with a first binary signal, received between the third and second pads, and alternating between a second power supply voltage, greater than the first voltage, and a third voltage, smaller than the first voltage. The driver circuit is configured to determine a digital signal based on the values of a second binary signal on the fourth pad received during each of first pulses of the first binary signal at the third voltage and to control the light-emitting diode from the digital signal.
