White light source for LCD backlight

An apparatus for backlighting a liquid crystal display, the apparatus comprising:

• a color mixing optical fiber for mixing red green and blue light in the color mixing fiber to produce white light, the color mixing optical fiber having a first end adapted for receiving red green and blue light and a second end adapted for delivering the white light;
• means for directing red green and blue light into the first end of the color mixing optical fiber;
• and
• means for conducting the white light out of the second end of the color mixing fiber to the liquid crystal display.
