Patent ID: 6906691

Claim:
An LCD device, comprising: a liquid crystal panel having a plurality of pixels; a backlight for supplying light; a timing control circuit for generating a gate clock signal and a plurality of control signals, sensing whether or not data to be displayed in said liquid crystal panel is toggled, and generating a control signal for controlling a brightness of said backlight according to sensed results; a gray scale voltage generating circuit for generating a plurality of gray scale voltages corresponding to said data to be displayed in said liquid crystal panel in response to said gate clock signal; a gate driving circuit for scanning the pixels of said liquid crystal panel a row at a time in order, in response to the gate clock signal; and a source driving circuit for generating liquid crystal driving voltages corresponding to the data to be displayed in said liquid crystal panel in response to the gray scale voltages and the control signals, and outputting generated liquid crystal driving voltages to said liquid crystal panel.
