    Abstract: Configurations for display stacks of an electronic device and methods for mitigating crosstalk are disclosed. The display stack may include a transceiver module, which may be located under or behind the display. The transceiver module may include a transmitter module, which may provide polarized light from the transmitter that may suppress module crosstalk. The transceiver module also may include a receiver module, which may include polarization control elements and an analyzer for differentiating between a target signal and a crosstalk signal. The polarization control on both the transmitter module and receiver module sides may suppress the crosstalk signals, which may be due to the reflections between and within the elements of the display stack and resulting from positioning the transceiver module behind the display.

    Abstract: A device includes a display stack and an optical receiver. The display stack includes a set of opaque elements defining a translucent aperture. The translucent aperture extends through the display stack. The optical receiver is spaced apart from and behind a back surface of the display stack. At least one micro-optic element is formed on the back surface of the display stack, between the display stack and the optical receiver. The at least one micro-optic element includes a micro-optic element having a focal point located within the translucent aperture. The optical receiver is configured to receive light through the translucent aperture and the at least one micro-optic element.

    Abstract: A light-emitting device includes a semiconductor substrate, a surface-emitting semiconductor light source on the semiconductor substrate, a monolithic first dielectric, and a second dielectric. The monolithic first dielectric is transparent to light emitted by the light source and includes first and second micro-lenses adjacent an aperture of the light source and having axes parallel to and offset from an axis of a beam of light emitted by the light source, and a saddle-shaped lens over the aperture of the light source. The saddle-shaped lens connects the first and second micro-lenses and reshapes the beam of light emitted by the light source to have a high aspect ratio. The second dielectric is transparent to light emitted by the light source and encapsulates a light emission surface of the saddle-shaped lens. The second dielectric has a higher refractive index than the monolithic first dielectric.

    Abstract: An electronic device may include an optical proximity sensor system. The optical proximity sensor system may be a transreflective optical proximity sensor system having a light emitter that emits light into a light-emitting region and a light detector that detects light in a light-detecting region. Control circuitry in the device can use the transreflective optical proximity sensor system to detect objects in an object detection region formed where the light-emitting region and light-detecting region overlap. The electronic device may be a pair of headphones in which housing structures such as housing walls define ear cup cavities. Speakers may be provided in the ear cups of the headphones to provide sound to the ear cup cavities. The transreflective optical proximity sensor system can detect the presence of a user's ear in an ear cup cavity.

    Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. To determine whether the light emitter has caused these artifacts, a display light sensor under the display may measure backside light leakage from the display. Based on the measured backside light leakage, the display light sensor or control circuitry may determine whether artifacts in the display exceed a predetermined acceptable artifact range. If the artifacts exceed this range, the artifacts may be mitigated. To mitigate the artifacts, the light emitter and/or the display may be adjusted. For example, the timing and/or dosage of the light emitter, the acceptable artifact range, and/or the timing of display content may be adjusted. In this way, the display light sensor may be used to form a closed-loop system to determine whether artifacts are present in the display and to mitigate those artifacts.

    Abstract: In some embodiments, a display stack includes a set of light-emitting elements, and a display backplane that includes a set of conductors and is electrically coupled to the set of light-emitting elements. A conductor in the set of conductors has a length, and a curved edge extending along at least a portion of the length. In some embodiments, a display stack includes a set of light-emitting elements; a set of transistors, electrically coupled to the set of light-emitting elements; and a set of conductors, electrically coupled to the set of transistors. The set of transistors may be electrically coupled to the set of conductors at a set of conductive pads. A plurality of conductive pads in the set of conductive pads is coupled to a single conductor in the set of conductors. The single conductor approaches different conductive pads in the plurality of conductive pads at different angles.
