摘要： A backlight unit includes light source groups, a converter, a compensator, a detector and a protector. Each of the light source groups includes a light source, and the converter boosts an input voltage to a driving voltage that is supplied to the light source groups. The compensator is connected to the light source groups and compensates a deviation between currents fed back to the compensator from each of the light source groups. The detector is connected between the compensator and the light source groups and detects a maximum voltage from among feedback voltages fed back to the compensator from each of the light source groups. The protector is connected to the detector and receives the maximum voltage, and compares the maximum voltage to a reference voltage to generate a compared result. The protector outputs a protection signal to the converter based on the compared result.
