Thread Starter 
So, I know very little about circuits but... Why do CCFL backlights need inverters?

Something that piqued my interest consisting my monitors inverter just died.

A CCFL inverter is an electrical inverter that supplies alternating current power to a cold cathode fluorescent lamp (CCFL). CCFLs are often used as inexpensive light units in electrical devices powered by direct current, such as batteries. CCFL inverters are small, have switchover efficiency over 80%, and offer adjustable output of light. They are widely used for backlights for LCDs, or for rear lighting in advertising signs.

Basicall it inverts(converts) the AC(alternating current) power to DC(direct current) power for the CCFL
