摘要：The rapid development of consumer electronics and trend of reducing the size and weight of power supplies is becoming more and more important. The development of flat panel display technology, liquid crystal display (LCD) panels have become common. As the LCD panels are transmissive displays, they need backlight illuminations. To date, cold cathode fluorescent lamps (CCFLs) have been widely used as the backlight source for large LCD panels to provide the backlight illuminations. They are considered to be one of the best backlight sources when considering factors such as cost, efficiency, and uniformity ratio of illumination.
