A scanning backlight type LCD(Liquid Crystal Display) and a driving method thereof are provided to set the on/off periods of plural backlights differently, thereby removing the motion blur of an image. An LCD panel(100) displays an image. A driving driver(120) is connected with an external system, receives a control signal and a data signal and drives the LCD panel. The driving driver also analyzes the degree of the motion blur of the data signal and controls the plural backlight lamps as plural logically divided block units. A backlight unit(140) includes plural back light lamps, turns on/off the backlight lamp according to the control of the driving driver and supplies the light beam to the LCD panel by plural block units. A power member(150) supplies the driving power to the LCD panel, the driving driver and the backlight unit. The driving driver includes an interface(122) connected with the external system and for transmitting the control signal and the data signal. An image analyzing member is connected with the interface, compares the difference of the data signal by frames, analyzes the degree of the motion blur and supplies the result to the backlight unit. A timing controller(124) is connected with the image analyzing member and generates the gate and data control signal. Gate and data drivers(126,128) are connected with the timing controller and drive the LCD panel. A reference voltage generating member(129) is connected with the power member and supplies the plural reference voltage to the data driver. |
