Cold Cathode Florescent Lamps (CCFLs) provide the light that most LCDs use to produce an image. Sometimes technology transitions are subtle and take place over many years. More often than not they are dramatic, sudden, and absolute.... especially in display technology. Sam Matsuno of DisplaySearch, first came to prominence when he described the tipping point when LCDs would not only start replacing CRTs but that the transition would proceed rapidly. In notebook technology, the transition from the market being 80% monochrome to being 95% color only took about 9 months. (The transition from 4:3 to 16:10 followed a similar path.) Color LCDs reached a tipping point where there ceased to be any cost advantage to monochrome. Now we may have just such a tipping point in LCD backlights.
