Description

Device and method for mitigating diffraction effects of an electronic device having a plurality of optoelectronic components RELATED APPLICATIONS The present application claims the benefit of priority from U.S. provisional patent application No. 63/578,758, filed on 8/2023, the contents of which are incorporated herein by reference in their entirety. Technical Field The present disclosure relates to electronic devices having a display panel and a plurality of optoelectronic components, and in particular to mechanisms for mitigating diffraction effects when such optoelectronic components exchange light through at least one transmissive region of the display panel. The display panel may be one of and include a layered semiconductor device, which in some non-limiting examples may be an optoelectronic device having a plurality of (sub) pixel emission regions, each comprising a first electrode and a second electrode separated by at least one semiconductive layer. Background In an optoelectronic device such as an Organic Light Emitting Diode (OLED), at least one semiconductive layer including an emissive layer may be disposed between a pair of electrodes, such as an anode and a cathode. The anode and cathode may be electrically coupled to a power source and generate holes and electrons, respectively, that migrate toward each other through the at least one semiconductive layer. When a pair of holes and electrons combine, the emissive layer may emit light in the form of photons. An OLED display panel, such as an Active Matrix OLED (AMOLED) panel, may include a plurality of pixels, each pixel further including a plurality of sub-pixels, including but not limited to one of three and four. In some non-limiting examples, various sub-pixels of a pixel may be characterized by at least one of three and four different colors including, but not limited to, R (red), G (green), and B (blue). Each (sub) pixel may have an associated emissive region comprising a stack of an associated pair of electrodes and at least one semiconductive layer between the electrodes. In some non-limiting examples, each sub-pixel of a pixel may emit light, including but not limited to photons, having an associated wavelength spectrum characterized by a given color, including but not limited to one of R (red), G (green), B (blue), and W (white). In some non-limiting examples, the (sub) pixels may be selectively driven by a drive circuit comprising at least one Thin Film Transistor (TFT) structure within a substrate electrically coupled to a conductive metal line, in some non-limiting examples, electrodes and at least one semiconductive layer deposited on the substrate. In some non-limiting examples, various coatings (layers) of such panels may be formed by vacuum-based deposition processes. In an AMOLED panel, a (sub) pixel may emit light when a voltage is applied between the anode and cathode of the (sub) pixel. By controlling the voltage applied between the anode and the cathode, the emission of light from each (sub-) pixel of such a panel can be controlled. In case a common cathode is provided across a plurality of (sub-) pixels, the voltage across the anode and the cathode in each (sub-) pixel may be controlled by adjusting the voltage of the anode. In some non-limiting examples, adjacent anodes may be spaced apart in a lateral orientation and at least one non-emissive region may be provided therebetween. In some non-limiting examples, such a panel may be housed in an electronic device, including but not limited to a mobile user device, such as a smart phone. In some non-limiting examples, such an electronic device may include an optoelectronic component that at least one of emits and receives light, including but not limited to a camera for capturing an image of light emitted from outside the electronic device. In some non-limiting examples, such user devices may include a mechanism for biometric authentication of the user prior to allowing the user to gain access to the user device. Such a mechanism may involve a facial identification system in which a grid of points of Infrared (IR) light are projected onto a user's facial surface, including but not limited to projection in a grid by an IR emitter, such as a point projector. The system captures an image of the projected point on the surface, including but not limited to through an IR camera, and generates a map therefrom. The generated graph may be compared to a reference graph and if there is sufficient correspondence between them, the user device may be unlocked, allowing the user to access its hardware and associated software. In some non-limiting examples, the facial identification system may include a flood illuminator for illuminating IR light at the facial surface of the user. While in some non-limiting examples at least one of the at least one optoelectronic component (including but not limited to a camera) and the component of the facial recognition system (including but not limited t
