The blue color of Zenith and some other monochrome LCD displays is caused by the
backlight. These displays use an electroluminescent panel behind the entire LCD screen,
and it gives off a blue light. Most current LCD displays use flourescent tubes either
behind or on the sides of the displays, with a variety of optical diffusers. Flourescent
tubes, of course, give off white light.
