摘要
A method of driving a light source driving circuit includes: applying driving signals, each having a reference frequency different than the reference frequency of other driving signals, to respective color light sources, each emitting a color light; generating a sensing signal based on a sensed mixed light emitted from the color light sources; filtering the sensing signal based on the reference frequency of each of the driving signals; generating color signals corresponding to each of the color light sources based on the filtered sensing signal; outputting light quantity control signals based on the color signals; and controlling a duty ratio of each of the driving signals based on the light quantity control signals to apply the driving signals, each having the controlled duty ratio, to the color light sources to control a quantity of the color light emitted from each of the color light sources.
