Abstract

A backlight unit includes a light source part including a light-emitting diode array, a DC/DC converter, a driving current controller, and a reference voltage variable part. The backlight unit is operated in a first mode or a second mode. The driving current controller controls a driving current flowing through the light-emitting diode array to have a first current level during the first mode and controls the driving current flowing through the light-emitting diode array to have a second current level during the second mode. The reference voltage variable part applies a first reference voltage to the driving current controller during the first mode and applies a second reference voltage to the driving current controller during the second mode.
