Abstract
A color display device (210, 310, 410) includes a backlight (214, 414) that cyclically emits first, second, and third component color backlighting in turn over a cycle period. The cycle period repeats at a cycling frequency (f) that exceeds a maximum human visual response frequency. A liquid crystal display (LCD) (112, 312, 412) generates a first display during the first component color backlighting, a second display during the second component color backlighting, and a third display during the third component color backlighting.
