摘要:
A backlight assembly includes; a plurality of light source strings which receive a driving voltage to generate a light, a driving circuit including a channel terminal commonly connected to output terminals of the plurality of light source strings and which receives a feedback voltage through the channel terminal to control the driving voltage according to the feedback voltage, and a current detection circuit connected to the output terminals of the plurality of light source strings to receive currents from the plurality of light source strings and which turns off the driving circuit when at least one of the received currents is larger than a predetermined reference current.
