Abstract (en)
[origin: WO2020084226A1] Method for manufacturing an optoelectronic device (10), comprising the steps of: forming a substrate (11) having a support face (111); forming a first series of first areas (131, 131a) suitable for forming all or some of the light-emitting diodes (13), forming a second series of second areas (151, 151a) on the support face (111) which are suitable for forming a light confinement wall element (152) capable of forming a light confinement wall (15), the second areas (151, 151a) being distinct from the first areas (131, 131a), the second areas (151, 151a) defining sub-pixel areas (14) between them; forming, from the first areas (131, 131a), light-emitting diodes (13); forming, by the same technique as in the previous step, from the second areas (151, 151a), light confinement wall elements (152), concomitantly with all or some of the light-emitting diodes (13) formed inthe previous step.
