Abstract: A method of driving a light-source module includes adjusting a frequency of a boosting switching signal based on a dimming signal which controls luminance of a light-emitting diode (“LED”) string of the light-source module, where the LED string comprises a plurality of LEDs connected to each other in series, and controlling a main transistor in response to the boosting switching signal to transfer a driving voltage to the LED string.
