摘要： A backlight unit includes a driving circuit, a plurality of light source strings, and an error detector. The driving circuit outputs a driving voltage. Each of the light source strings includes a plurality of light sources and receives the driving voltage through input terminals of the light source strings to generate a light. The error detector is connected to output terminals of the light source strings and senses voltages between the input terminals and the output terminals of the light source strings to detect an error in the light sources using a first voltage and a second voltage. The first voltage is a voltage difference between a maximum and a minimum of the sensed voltages and the second voltage is obtained by dividing one sensed voltage of the sensed voltages by a number of the light sources of a light source string from which the one sensed voltage is sensed.
