Abstract
An optoelectronic device including at least an emissive component including at least a first electrode, a second electrode, and an emissive element disposed between an emissive face of the optoelectronic device and the second electrode, a photodetector component such that the second electrode of the emissive component is disposed between the photodetector component and the emissive element. The emissive component and the photodetector component are superimposed one above the other, and the second electrode has at least one hole passing through it, disposed vertically in line with at least a part of a detection surface of the photodetector component and/or a part of the detection surface of the photodetector component is not disposed vertically in line with the second electrode and form a ring located at the external edges of the detection surface of the photodetector component.
