Claim 17:
18. The controlling method according to claim 17, wherein each optical system comprises an optical lens configured so as to be traversed by at least part of the light beams likely to be emitted by the primary and secondary sub-pixels which it covers while ensuring their optical transformation in order to emit at the output a transformed light beam at least in part made directional in a main direction and in which the optoelectronic device comprises at least one collimation angle changing element configured to act on at least one of the optical systems so as to selectively place its optical lens among a plurality of distinct optical configurations where the angle formed between the main direction and the substrate varies from one optical configuration to another optical configuration, the controlling method being such that the phase comprises a step e), implemented before step c), including actuating the collimation angle changing element so as to vary the angle formed between the main direction and the substrate at least once so as to place the optical lens successively in at least two distinct optical configurations.
