Abstract: The present disclosure relates to a backlight unit, a display device, and a driving method. A sensing MUX circuit senses a voltage of a first light emitting node and a voltage of a second light emitting node, and then, detects whether a first light source connected between the first light emitting node and the second light emitting node is defective, whereby it is possible to specify and detect a defective light source.
