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.

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: An optical sensing system includes a transmitter side and a receiver side, and is configured to be positioned below a display of an electronic device. The transmitter side includes a light emitter, a temperature sensor, and a photodiode. The receiver side includes a photodiode and a temperature sensor. The optical sensing system includes an application-specific integrated circuit that leverages the temperature sensors, the photodiodes, and one or more signal filters such as a high-pass filter to perform multiple field calibrations of the optical sensing system, thereby improving accuracy and precision thereof.

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.
