Patent ID: 7477272

Claim:
A driving method for displaying a normal mode signal in a wide mode liquid crystal display (LCD) device, for displaying an analog video signal having a horizontal back porch input to the wide mode LCD device as a normal mode, the method comprising: outputting a source start pulse (SSP) signal; latching pixel data for a black display by using a main clock signal having a first period synchronized to the SSP signal; first skipping latch of the pixel data for the black display during a first transition period of the video signal by using a clock enable signal disabled at the first transition period of the video signal; latching pixel data corresponding to a normal mode by using a modulated clock signal having a second period that is longer than the first period, and outputting the latched pixel data; and second skipping latch of the pixel data corresponding to a normal mode during a second transition period of the video signal by using the clock enable signal disabled at the second transition period of the video signal.
