Abstract
A backlight unit includes a light source module including a first connection pin and a second connection pin electrically connected to the first connection pin, a power converter which provides a driving voltage to the light source module, a connector which receives a first enable signal via a first signal line and provides a second enable signal via a second signal line and a driving circuit which controls a generation of the driving voltage from the power converter in response to the second enable signal. When the connector is electrically connected to the first and second connection pins, the first enable signal is transmitted to the first connection pin via the first signal line and the connector, and the second enable signal from the second connection pin is provided to the driving circuit via the connector and the second signal line.
