Method of driving light source and display apparatus for performing the method

A display apparatus comprising:

• a display module;
• and
• a light source module which supplies light to the display module to display an image,
• wherein the light source module comprises:
• a light source part including a plurality of light emitting strings and which supplies the light to the display module;
• an inverter which inverts a direct current voltage to generate a first alternating current voltage;
• a transformer which transforms the first alternating current voltage into a second alternating current voltage and outputs the second alternating current voltage;
• a compensator which compensates 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 the plurality of light emitting strings;
• and
• a rectifier which rectifies the compensated driving alternating current voltage and applies a driving voltage to the light emitting strings.
