    Abstract: An electronic device may be provided with a display. The display may include a backlight having an array of locally dimmable light sources. Control circuitry may provide control signals to the backlight to produce light at different brightness levels. When the brightness level is below a threshold, the control circuitry may use pulse-width-modulation control signals to control the light sources in the backlight. When the brightness level is above the brightness threshold, the control circuitry may use analog control signals to control the light sources in the backlight. The control circuitry may adjust the threshold to achieve different dimming ranges for different brightness settings. A low brightness setting, for example, may have a lower threshold and lower dimming range than a high brightness setting, which may help produce darker darks when the display operates in a low brightness setting.

    Abstract: Systems, methods, and computer readable media that improve the gamut size for a multi-layer display. Various embodiments receive a color input value indicative of a target display color associated with an input image and determine a color saturation value for the received color input value. Based on the color saturation value, a drive value for a monochromatic modulation panel and a drive value for a color modulation panel may be determined. The various embodiments can then drive the monochromatic and color modulation panel according to the drive values. The monochromatic modulation panel is not modulated until the color modulation panel is driven to full illumination.

    Abstract: Parameters of a display may be adjusted in response to accessing a time value corresponding to an electronic device that includes the display. A brightness value of the display may be adjusted based on the time value to maintain a display characteristic value within a predefined range and below a threshold. The display characteristic value may be independently controllable by one of the brightness or the color temperature of the display. A set of red green blue (RGB) color values of the display may be adjusted independent of the adjustment to the brightness value to maintain the display characteristic value within the predefined range and below the threshold while maintaining the brightness value of the display. In some examples, the RGB color values of the display may be adjusted at approximately the same time as the adjustment of the set of RGB color values of the display is performed.

    Abstract: An electronic device may include a display and control circuitry that operates the display. The control circuitry may be configured to daltonize input images to produce daltonized output images that allow a user with color vision deficiency to see a range of detail that the user would otherwise miss. The daltonization algorithm that the control circuitry applies to input images may be specific to the type of color vision deficiency that the user has. The daltonization strength that the control circuitry applies to the image or portions of the image may vary based on image content. For example, natural images may be daltonized with a lower daltonization strength than web browsing content, which ensures that memory colors such as blue sky and green grass do not appear unnatural to the user while still allowing important details such as hyperlinks and highlighted text to be distinguishable.
