The disclosed embodiments provide a method and apparatus for optimizing power efficiency in liquid crystal displays. A microprocessor or embedded microcontroller associated with circuit control modules eliminates redundancy by allowing a single inverter to equalize the intensity of illumination for an array of multiple CCFLs. The microcontroller optimizes power management by continuously sensing the operating currents of every lamp and automatically adjusts for variations in illumination of individual lamps by parallel switching of capacitance that ensures an equal current is applied to each lamp. The microcontroller produces the appropriate control signals and executes a digital servo control algorithm to modify the currents for carrying out the luminance adjustments.
