Abstract: Scalable color balancing techniques for processing images to be presented on displays are described. One technique includes receiving ambient light color information from an ambient light sensor and input image data to be presented via a display coincident with receiving the ambient light color information. The display may have a first white point at a time prior to receiving the input image data. The technique may include determining a second white point for the display based on the input image data and the ambient light color information. The first and second white points may differ from each other. The technique may also include generating one or more chromatic adaptation transforms (CATs) based on the white points. Output image data may be generated based on applying the one or more CATs to the input image data. The output image data may be presented via the display. Other embodiments are described.

Abstract: An electronic device may be provided with a display having a backlight with light sources of different colors. The electronic device may include a color ambient light sensor that measures the color of ambient light and control circuitry that adjusts the color of light emitted from the backlight based on the color of ambient light. The light sources may include at least first and second light-emitting diodes that emit light having different color temperatures. The control circuitry may adjust the intensity of light emitted from the first light-emitting diode relative to the intensity of light emitted from the second light-emitting diode to produce a backlight color that more closely matches the color of ambient light. The first and second light-emitting diodes may include an ultraviolet light-emitting diode die and a blue light-emitting diode die that are mounted in a common semiconductor package.

Abstract: An electronic device may include a peripheral conductive housing sidewall with an integral ledge extending towards the device interior. A display cover layer may be supported by the integral ledge. A slot antenna may be formed from a slot in the integral ledge. The integral ledge may be mounted to a surface of a substrate and coupled to a conductive rear housing wall by a conductive layer extending over an additional surface of the substrate. The sidewall may include a vertical portion extending from the ledge to the rear wall. The slot antenna may be fed via near-field coupling using a conductive patch that is located within the slot at the surface of the substrate. The conductive layer, rear housing wall, and vertical portion may form a cavity for the slot antenna. The conductive layer may isolate the slot from interference with a battery, display circuitry, or other components.

Abstract: An electronic device may be provided with a display, display control circuitry that operates the display, and a color ambient light sensor that gathers ambient light information. Display color cast may be adjusted based on the ambient light information. When the color of ambient light is within an acceptable range of colors, the color cast of the display may be adjusted to more closely match the color of ambient light. When the color of ambient light is outside of the acceptable range of colors, display control circuitry may determine an adjusted ambient light color that is within the acceptable range. The adjusted ambient light color may have the same color temperature as the measured ambient light color. After determining an adjusted ambient light color that is within the acceptable range, the color cast of the display may be adjusted to more closely match the adjusted ambient light color.

Abstract: One embodiment describes an electronic display. The electronic display includes display driver circuitry that displays at least a first image frame and a second image frame on the electronic device using a first display pixel and a second display pixel. The electronic display also includes touch sensing circuitry that detects user interaction with the electronic display. A timing controller of the electronic display determines at least a first insertion time for a first intra-frame pause for the first image frame and a second insertion time for a second intra-frame pause for the second image frame. The first and second intra-frame pauses are periods where the display driver circuitry is pauses rendering of image data to allow the touch sensing circuitry to detect user interaction. The insertion times for the first and second intra-frame pauses are varied from one another. The timing controller inserts the first intra-frame pause during rendering of the first image frame at the first insertion time and inserts the second intra-frame pause during rendering of the second image frame at the second insertion time.
