<p>PURPOSE: A light emitting diode driver is provided to be cost-effectively manufactured by providing current balancing between light emitting diode strings. CONSTITUTION: A light emitting diode driver includes first light emitting diode strings(103), second light emitting diode strings(104), a first rectifier(107), a second rectifier(108), and a balancing part(105). The first rectifier rectifies a first direction current of an alternating current voltage and supplies the rectified current to the first light emitting diode strings. The second rectifier rectifies a second direction current of the alternating current voltage and supplies the rectified current to the second light emitting diode strings. The balancing part is located between the light emitting diode strings in order to balance the current of the light emitting diode strings.</p> |
