About CCFL Controllers IC
CCFL controllers provide control functions for the direct-drive inverters that are used to operate cold cathode fluorescent lamps (CCFL). A CCFL lamp consists of a phosphor- coated glass cylinder with cathodes at each end. Cold cathode light is used mainly for CCFL backlight or edge-lighting of liquid crystal flat panel displays (LCFPD). With a CCFL controller, the lamp filament does not require preheating and the electrodes in the bulb are maintained at low temperatures. CCFL inventers and CCFL capacitors are important parts of CCFL controllers. A CCFL inverter is the cold cathode lighting source used to drive the CCFL lamp. A CCFL capacitor allows the output voltage from the transformer to be applied to the electrodes.
