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.
