An apparatus and a method for driving a backlight are provided to reduce the number of light emitting diode drivers and light emitting diode driving controllers by simultaneously driving a plurality of light emitting diode strings by using a multi-output transformer. A plurality of light emitting diode strings(136-1~136-n) includes a plurality of light emitting diodes arranged in series and connected with each other. A transformer unit transforms an input voltage to supply a plurality of driving voltages to the plurality of light emitting diode strings. A light emitting diode driving unit supplies the generated driving voltages to the plurality of light emitting diode strings. |
