摘要： A light source apparatus includes a plurality of light source parts, a power supply part, a current selection part and a current control part. The plurality of the light source parts are connected in parallel and the power supply part provides power to a first terminal of each of the light source parts. The current selection part selects the current level of one of the light source parts as a reference current level. The current control part adjusts the levels of the currents flowing through the light source parts to be substantially equal to the reference current level. Selection of the light source part that provides the reference current level is dynamically changed.

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.
