ABSTRACT:
The fabrication method comprises a step of exposing at least one organic diode to a gas, before packaging of the device, to form a plurality of randomly distributed black spots by impairment. Increasing the exposure time enables the size of the black spots to be increased, also randomly. The surface distribution of the black spots, visible by electroluminescence, enables an object associated with this distribution to be identified in reliable manner.
