Abstract: An electronic display may include an ambient light sensor (ALS) located beneath an active area to sense ambient light above the active area. The ALS may have multiple response channels to perform fast sensing integration, which is synchronized with blanking periods of a pixel on the active area. An emission mask and a heat map may be generated for the ALS and used to generate a calibrated heat map for the ALS. The calibrated heat map of the ALS is used with display content to calculate a crosstalk compensation for the ALS.

Abstract: A head-mounted device may have a gaze tracking system and an optical sensor. The gaze tracking system may include a camera, ambient light sensor, or other optical sensor to determine an angle/direction of a user's gaze. The optical sensor may be a camera, directional color ambient light sensor, or other optical sensor. After determining the user's gaze, the optical sensor may be used to determine the color of an external object in the direction of the determined angle/direction. For example, the color of the external object may be determined in response to an input from the user, such as a button press, a voice command, or a blink. The determined color may be used as an input color in a virtual space or on another device.

Abstract: An electronic device may include a housing and relative humidity sensor in the housing. The relative humidity sensor may include an optical layer, a relative humidity-sensitive layer coupled to a surface of the optical layer, a light emitter that emits light into the optical layer, and a light detector that detects light that has reflected within the optical layer and off of the relative humidity-sensitive layer. The relative humidity may be determined based on the light detected by the light detector. The optical layer may be a layer with angled edges, a prism, a Bragg reflector, or a waveguide. A reference light detector and/or a temperature sensor may be included in the relative humidity sensor, and measurements from these additional sensors may be used in determining the relative humidity. In this way, an optical relative humidity sensor may be formed in the electronic device.

Abstract: An electronic device may include an ambient light sensor or other semiconductor sensor. The sensor may produce signals in response to light incident on the electronic device and therefore incident on the sensor. In some cases, components within the electronic device, such as infrared components, or external light sources may interfere with the operation of the sensor. Therefore, the sensor may include a filter that transmits at least a portion of visible light while blocking infrared light. Because light may be incident on the electronic device from a variety of angles, a diffuser in the sensor may scatter the light into a desired angular distribution. To ensure that infrared light is blocked regardless of the angle of the incident light, the filter may include both thin-film dielectric layers and metal layers. The metal layers may be interleaved with the thin-film dielectric layers.
