Abstract: A device may include an electronic display having a backlight that generates light and multiple display pixels that modulate the amount of generated light emitted from the electronic display based on compensated image data. The backlight may include multiple illuminators that generate the light, and a first color component illuminator may have a slower response rate than a second color component illuminator. The device may also include image processing circuitry that generates the compensated image data by compensating input image data for a color shift associated with a change in brightness of the backlight and the slower response rate of the first color component illuminator. The input image data may be compensated by increasing first color component pixel values of the input image data relative to second color component pixel values of the input image data, and the compensated image data may be output to the electronic display.

Abstract: Systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

Abstract: An image display device and method are described for displaying an image distributed over plural display tiles. The image display device has a plurality of backlight light sources for illuminating plural display tiles. Contiguous zones of at least one image pixel are defined in each display tile such that each zone has at least one associated backlight light source. In particular for each edge zone of each display tile a backlight brightness driving level is determined based on brightness level target values of pixels of the edge zone and based on brightness level target values of pixels of at least one other zone of another display tile adjacent to the edge zone.

Abstract: An electronic device may be provided with a display. The display may be configured to display standard dynamic range image content and high dynamic range image content at the same time. The control circuitry may dynamically adjust an amount of headroom for the high dynamic range image content to avoid washing out the standard dynamic range image content. For example, the control circuitry may reduce the amount of headroom available for high dynamic range image content with high average pixel luminance levels and low screen coverage. The headroom may be increased as the average pixel luminance levels decrease and/or as screen coverage increases. Different high dynamic range images that are displayed at the same time may be assigned different amounts of headroom (e.g., different peak brightness levels) based on average pixel luminance values, screen coverage, whether or not the content is within an active window on the display, etc.
