  • Patent number: 11862093
    Abstract: A device including a display screen including display pixels arranged in rows and in columns, including a first row and a first column. The device further includes a display screen control circuit configured to, in a first mode, start the display of a first image on the first row and on the first column and, in a second mode, start the display of a second image on one of the rows different from the first row and/or on one of the columns different from the first column.

  • Patent number: 11552126
    Abstract: An optoelectronic device having a substrate and a plurality of sets of light-emitting diodes where each set includes a plurality of light-emitting diodes, a first lower electrode, a second upper electrode, an electronic component of an electronic circuit formed in a first portion of the substrate, on the side of the face of the substrate that does not bear the light-emitting diodes, and a first conductive means formed through the first portion and electrically connecting a first terminal of the electronic component to one amongst the first and second electrodes. The first conductive means of a given set is electrically-insulated from the first conductive means of the other sets.

  • Patent number: 11443686
    Abstract: A display screen including display circuits, each display circuit including a light-emitting diode, a controllable current source powering the light-emitting diode, and a control circuit capable of supplying a pulse-width modulated signal for controlling the current source from a periodic signal. The display screen further includes first electrodes coupled to the control circuits, a circuit for supplying a selection signal successively on each first electrode, and an oscillating circuit or oscillating circuits capable of supplying the periodic signals, the periodic signals being non-synchronous with the display circuit selection signals.

  • 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.
