Abstract:
A method of driving a light source includes; converting an externally supplied direct current voltage into a first alternating current voltage, boosting the first alternating current voltage to a second alternating current voltage having a higher voltage than the first alternating current voltage, turning on the light source using the second alternating current voltage, detecting an arc noise detection voltage by adding arc noise generated from a high voltage terminal of the light source and arc noise generated from a low voltage terminal of the light source, and blocking the high voltage from being provided to the light source based on the detected arc noise detection voltage.
