Abstract
A method of driving a light source apparatus includes inverting a direct current voltage to generate a first alternating current voltage, transforming the first alternating current voltage into a second alternating current voltage having a voltage level that is greater than a voltage level of the first alternating current voltage, compensating a driving alternating current voltage based on the second alternating current voltage to generate a compensated driving alternating current voltage such that a substantially equal current flows through each light emitting string of a plurality of light emitting string included in the light source apparatus, and rectifying the compensated driving alternating current voltage to apply a driving voltage to the light emitting strings.
