Abstract (en)
[origin: WO2020136348A1] The invention relates to an optoelectronic device (10) comprising a plurality of pixels (11), each pixel including a lighting mechanism (222) comprising at least one light-emitting diode (111) capable of emitting an initial light beam (121), a light-conversion module (600) comprising a plurality of conversion pads including at least one primary conversion pad (11a) and at least one secondary conversion pad (11b). Each pixel comprises a light-adjustment system configured to control at least one element chosen from a relative position between the lighting mechanism (222) and the light-conversion module (600) and the initial light beam (121). The action of the light-adjustment system is adapted so that the primary conversion pad (11a) and the secondary conversion pad (11b) emit a first light beam (124a) and a second light beam (124b) respectively, from the initial light beam (121), simultaneously or alternately in a predetermined sequence.
