1. A method for driving an LCD device capable of controlling a viewing angle comprising:
- driving the LCD device in an fringe field switching (FFS) mode during a frame frequency period to obtain a wide viewing angle; and
driving the LCD device in both the FFS mode and a viewing angle control (VAC) mode during the frame frequency period by dividing the frame frequency period, thereby obtaining a narrow viewing angle.
