  • Patent number: 11929040
    Abstract: A user interface display may have a display and may have a backlight that lights the display. The display may implement pixels to generate colors and images. The display may be backlit. The backlight may use pixels having emitters to generate different color backlighting. In various instances, the display or the backlight or both may include a deep blue emitter. The blue emitter may be used in combination with red and green pixels elements to generate different colors. By implementing deep blue emitters rather than conventional blue (e.g., cyan) emitters, the effects of cyan light on a viewer's circadian rhythm may be limited or eliminated. Moreover, by implementing deep blue emitters, the effects of cyan light on a viewer's circadian rhythm may be varied, while the colors and images are reproduced for viewing without introducing significant color distortion.
