摘要： A backlight unit includes a DC-DC converter that converts a first voltage to a second voltage in response to a driving pulse signal and a driving controller that outputs the driving pulse signal in response to an over-current control signal to control a reference voltage and a level of the second voltage. The driving controller controls the reference voltage in response to the over-current control signal such that the reference voltage increases prior to the second voltage by a predetermined time when the second voltage needs to be increased. In addition, the driving controller controls the reference voltage in response to the over-current control signal when the second voltage needs to be decreased such that the reference voltage decreases later than the second voltage by the predetermined time.

摘要： A backlight unit includes a power converter which generates a light driving voltage in response to a voltage control signal with a first level, a plurality of light emitting strings, wherein each of the light emitting strings receives the light driving voltage through a first end thereof, and a controller which generates the voltage control signal. The controller is connected to a second end of at least one of the light emitting strings and detects a level of a signal at the connected second end to detect an operation state of the light emitting strings. The controller generates the voltage control signal with a second level to stop the power converter from generating the light driving voltage when the operation state of the light emitting strings is in an abnormal state.
