    Abstract: An electronic device may have a display. The display may have light-emitting diode pixels or other pixels. Due to aging-induced degradation of the pixels, the output intensity and color of the pixels may vary over the lifetime of the display. Control circuitry in the device may use an ambient light sensor to measure ambient light and stray display light. The display light measurements may be used in monitoring aging effects so that the control circuitry can compensate for aging-induced pixel degradation. Display light measurements may be made over a sequence of image frames. The image frames in the sequence of frames may include white and black frames or frames of different colors interleaved with black frames. Different frame intensities may be used during measurements of stray display light to gather gamma curves for the display.

    Abstract: Systems, methods, and computer-readable media for managing comfort states of a user of an electronic device are provided that may train and utilize any suitable comfort model in conjunction with any suitable environment data when determining a predicted comfort state of a user at a particular environment (e.g., generally, at a particular time, and/or for performing a particular activity).

    Abstract: A display may include pixels (such as light-emitting diode pixels) that are susceptible aging effects (burn-in). To help avoid visible artifacts caused by burn-in during operation of the display, compensation circuitry may be used to compensate image data for the display. An optical sensor may be included behind the pixels to directly measure pixel brightness levels. The optical sensor may provide optical sensor data from testing operations to the compensation circuitry. The optical sensor may gather data during burn-in testing operations. During the burn-in testing operations, pixel groups including both high-usage pixels and low-usage pixels may sequentially emit light while the optical sensor gathers data. Brightness differences between the high-usage pixels and low-usage pixels may be used to characterize pixel aging in the display and compensate image data to mitigate visible artifacts caused by burn-in. The optical sensor may also gather data during global brightness testing operations.

    Abstract: An electronic device may have a display with an array of pixels configured to display images for a user. The electronic device may have an ambient light sensor for gathering ambient light information. A set of the pixels may overlap the ambient light sensor so that ambient light measurements may be made on ambient light passing through the set of pixels. Control circuitry in the electronic device may control light transmission through the set of pixels so that different light transmission levels can be used in different ambient light conditions. Directional light measurements may be made by moving transparent pixels dynamically across the surface of the display overlapping the light sensor and/or by using pixelated light modulators to vary the angle of light rays measured by the ambient light sensor.

    Abstract: A device such as a computer stylus may have a color sensor. The color sensor may have a plurality of photodetectors each of which measures light for a different respective color channel. The color sensor may also have one or more light-emitting devices. Control circuitry may use the light-emitting devices to illuminate an external object while using the photodetectors to measure reflected light to determine the color of the external object. The electronic device may have a housing with an elongated shaft. The shaft may have a tip and an opposing end. The tip may be configured to emit electromagnetic signals that are detected by a touch sensor in a touch sensitive display. The color sensor may be located at the end opposite the tip, may be located at the tip, or may be optically coupled to the tip using a light guide.

    Abstract: An electronic device such as a portable electronic device may include a single-shot alignment-free spectrometer with no moving parts. The spectrometer may include a diffractive member, such as a grating, an aperture, and an image sensor that generates data in response to incident light. The diffractive member may diffract the incident light based on its wavelength and angle of incidence, and the aperture may further encode the light. The data generated by the image sensor may be used by control circuitry in combination with correlations between spectrometer measurements and known light profiles to determine the wavelength and angle of incidence of the light. These correlations may be determined using a deep neural network. Control circuitry may adjust one or more settings of the electronic device based on the wavelength and angle of incidence, or may use the wavelength and angle of incidence to determine information regarding an external object.
