Patent ID: 8106877

Claim:
A driving apparatus of a liquid crystal display device, comprising: a driving controller that reduces or restores a duty ratio of a driving control signal which controls a generation of a driving current of a backlight assembly in accordance with whether a predetermined enable signal is applied or not; a master inverter that reduces or restores a level of a driving current of the backlight assembly in accordance with a duty ratio of a driving control signal from the driving controller; a slave inverter that reduces or restores a level of a driving current of the backlight assembly in accordance with a duty ratio of the driving control signal; and a current limiting circuit that applies the predetermined enable signal to a ground or the driving controller in accordance with a phase of feedback currents from the master inverter and the slave inverter, wherein the predetermined enable signal is supplied to the driving controller when an output signal of the master inverter and a output signal of the slave inverter have the same phase, and wherein the predetermined enable signal is not supplied to the driving controller when the output signal of the master inverter and the output signal of the slave inverter have the different phase.
