Claim:
1. A method of manufacturing an optoelectronic device, comprising the steps of: (a) forming an array of light-emitting diodes, each light-emitting diode having a lateral dimension smaller than 30 μm; and (b) forming photoluminescent blocks opposite at least part of the light-emitting diodes, each photoluminescent block comprising semiconductor crystals having an average size smaller than 1 μm, dispersed in a binding matrix, wherein step (a) comprises manufacturing an optoelectronic circuit comprising the light-emitting diodes and wherein step (b) comprises forming non-through openings in a substrate, forming the photoluminescent blocks in some of the openings, bonding the substrate to the optoelectronic circuit and thinning the substrate to expose the photoluminescent blocks.
