  • METHOD FOR MANUFACTURING A COLOUR-CONVERSION OPTOELECTRONIC DEVICE, INCLUDING A STEP OF POLARISING AN ELECTRET LAYER IN A LOCALISED MANNER BY MEANS OF THE UPPER ELECTRODES OF THE DIODES
    Publication number: 20250081685
    Abstract: The invention relates to a method for manufacturing an optoelectronic device (1) including an array of diodes (D1, D2, D3) and an array of colour conversion portions (P1, P2), including the following steps: providing the array of diodes (D1, D2, D3), and the upper electrode layers (E1, E2, E3); depositing a dielectric layer (26) having a substantially zero surface potential; applying a potential difference between an electrode (2) and the first upper electrode layers (E1), resulting in the formation of first patterns (M1) with non-zero surface potential in the dielectric layer (26); producing the first colour conversion portions (P1), by contacting the dielectric layer (26) with a colloidal solution (S1) containing first photoluminescent particles (p1).

  • METHOD FOR MANUFACTURING A COLOUR CONVERSION OPTOELECTRONIC DEVICE, INCLUDING A STEP OF OPTICALLY FORMING SURFACE POTENTIAL PATTERNS IN AN ELECTRET LAYER
    Publication number: 20250056934
    Abstract: A method for manufacturing an optoelectronic device including an array of diodes and photoluminescent pads arranged opposite at least one diode, including making an electret layer over the array of diodes, by localized polarization or depolarization, optically, so as to form surface potential patterns; and making the photoluminescent pads, by contact of the electret layer with a colloidal solution containing photoluminescent particles, which are then deposited over the upper face of the electret layer opposite the predefined surface potential patterns, thereby forming the photoluminescent pads.

  • Acoustic attenuation panel comprising a front skin and a central structure
    Patent number: 11629644
    Abstract: An acoustic attenuation panel for a propulsion assembly includes an acoustic front skin having perforations, and a central structure formed from partitions arranged perpendicularly in order to make up cells, wherein the front skin and the central structure form the panel which is made as a single piece and is provided for directly covering a surface of an element of the propulsion assembly forming a rear skin which closes the cells of the central structure at the rear.
