Abstract:
A method of driving a light source includes receiving an alternating current (“AC”) voltage from outside, generating a first direct current (“DC”) voltage based on the AC voltage, generating a second DC voltage, corresponding to a difference between a driving voltage of a light source part and the first DC voltage, based on the first DC voltage, and outputting a sum of the first DC voltage and the second DC voltage to the light source part
