Neon lamps primarily rely on excitation of gas molecules to emit light; CCFLs use a discharge in mercury vapor to develop ultraviolet light, which in turn causes a fluorescent coating on the inside of the lamp to emit visible light. Cold-cathode fluorescent lamps were used for backlighting of LCDs, for example computer monitors and television ...
