Abstract: Automatic display brightness adjustments may be made by an electronic device based on ambient light sensor data. Proximity sensor data from a light-based proximity sensor, from nearby capacitive sensor electrodes in a touch screen, or from other proximity sensing components may be used to determine whether the ambient light sensor is being shadowed by a hand or other external object. Ambient light sensor data associated with blocked sensor conditions can be suppressed. A transient event filter may be used to remove spikes from ambient light sensor data. A display brightness baseline may be adaptively adjusted. Short changes in ambient light level may result in corresponding momentary adjustments to display brightness. Longer changes in ambient light level may be associated with persistent changes in the display brightness baseline.

Abstract: An electronic device may include a display and display control circuitry. The display may be calibrated to reduce color non-uniformity in the display. Display calibration information may be obtained during manufacturing and may be stored in the electronic device. The display calibration information may include color-specific, intensity-specific, location-specific correction factors. During operation of the display, display control circuitry may receive pixel data to be displayed by each pixel in the display. The pixel data may include color information and intensity information for each pixel. Based on the color information for each pixel, the intensity information for each pixel, and the location of each pixel in the display, the display control circuitry may determine a color-specific, intensity-specific, location-specific correction factor to apply to the pixel data for each pixel. Adapted pixel data may be supplied to each pixel in the display.
