ABSTRACT:
A monochromic, multi-color and full-color cold cathode fluorescent display (CFD), comprises of some shaped white or multi-color or red, green blue color cold cathode fluorescent lamps (CCFL), reflector, base plate, temperature control means, luminance and contrast enhancement face plate, shades and its driving electronics. CFD is a large screen display device which has high luminance, high efficiency, long lifetime, high contrast and excellent color. CFD can be used for both outdoor and indoor applications even at direct sunlight, to display a character, or graphic and video image.
