Abstract
A method for driving the backlight unit of the liquid crystal display includes: comparing the strength of a soft start signal with a predetermined signal through a comparator circuit, and generating a first comparison signal or a second comparison signal according to the comparison result; outputting a first frequency from a frequency modulation circuit according to the first comparison signal; and increasing the rising rate of the output voltage of a boost converter according to the first frequency. Therefore, the rising rate of the output voltage is increased, thereby solving the screen-flickering problem.
