Claim 16:
17. A method for controlling an optoelectronic device configured to emit light, in particular to display images, or to capture light, in which the optoelectronic device comprises:
at least one set of primary pixels where each primary pixel is arranged on a free surface of a substrate and comprises at least one primary sub-pixel capable of emitting a primary light beam on the side opposite the substrate,
at least one set of secondary pixels where the secondary pixels are arranged on the free surface of the substrate alternately with the primary pixels so that each primary pixel is adjacent to at least one secondary pixel and each secondary pixel comprises at least one secondary sub-pixel capable of emitting a secondary light beam on the side opposite the substrate,
a set of optical systems where each optical system is arranged so as to be able to cover, on the side opposite to the substrate, both the entirety of a pixel belonging to one of the sets of pixels selected from the set of primary pixels and the set of secondary pixels and at least part of the sub-pixels of at least one of the adjacent pixels belonging to the other of the sets of pixels, each optical system being configured to act optically on all or part of the light beams likely to be emitted by the sub-pixels belonging to the pixels that it covers, the total number of pixels of the sets of primary and secondary pixels being greater than or equal to twice the number of optical systems contained in the set of optical systems,
at least one displacement mechanism making it possible to apply a sequential relative movement between the set of optical systems and the sets of pixels in a predetermined sequence,, the controlling method comprising, for the implementation of said predetermined sequence, a phase repeated periodically over time and comprising the following steps:
a) controlling said at least one displacement mechanism in a manner allowing each optical system to be placed in a first position in which the optical system simultaneously covers all of the primary sub-pixels of one of the primary pixels and part of the secondary sub-pixels of at least one of the adjacent secondary pixels or in a second position in which the optical system simultaneously covers all of the secondary sub-pixels of one of the secondary pixels and part of the primary sub-pixels of at least one of the adjacent primary pixels,
b) acting on the primary pixel or the secondary pixel of which all the sub-pixels are covered by the optical system following step a) so as to place it in a first light configuration in which all of the sub-pixels which compose it emit a light beam,
c) controlling said at least one displacement mechanism in a manner allowing to displace each optical system to place it either in the second position if the optical system occupied the first position following step a), either in the first position if the optical system occupied the second position following step a), or in a third position in which the optical system simultaneously covers part of the primary sub-pixels of one of the primary pixels and part of the secondary sub-pixels of at least one adjacent secondary pixels, and
d) acting either on the primary pixel or the secondary pixel whose all the sub-pixels are covered by the optical system following step c) so as to place it in the first light configuration in which all the sub-pixels that compose it emit a light beam, or at the same time on at least one primary pixel whose primary sub-pixels are covered by the optical system following step c) so as to place it in a second light configuration in which at least one of the primary sub-pixels covered by the optical system emits a light beam and on at least one secondary pixel whose secondary sub-pixels are covered by the optical system following step c) so as to place it in a second light configuration in which at least one of the secondary sub-pixels (KO covered by the optical system emits a light beam.
