Abstract (en)
A color display comprises a backlight (152) and a display panel (150) for modulating the backlight output. The backlight comprises portions of four different colors, wherein the intensity of each color is independently controllable. The use of four colors enables more efficient color backlight device to be used in preference to less efficient color devices. For example, the backlight portions can comprise three non-white colors (84,86,82) and white (80). White light generation (with current technology) is more efficient than the generation of other colors.
