Patent ID: 7692621

Claim:
A liquid crystal display device comprising: a liquid crystal display panel including a liquid crystal interposed between two substrates, and a plurality of gate lines; and a backlight assembly having i) a signal synchronism part for detecting a gate line to which a gate driving signal is applied and generating an inverter control signal, ii) an inverter for receiving the inverter control signal to generate a lamp driving signal, and iii) at least two lamps parallel disposed under the liquid crystal display panel to be turned on or off in response to the lamp driving signal, wherein the inverter control signal generated from the signal synchronism part is a signal for turning off a portion of the lamps to stop supplying light to the liquid crystal corresponding to the gate line to which the gate driving signal is applied during a predetermined period of arranging the liquid crystal, after the gate driving signal is applied to the corresponding gate line, wherein the backlight assembly supplies the liquid crystal display panel with light continuously during one frame.
