Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel having a predetermined number of columns of data electrodes, a predetermined number of rows of scanning electrodes, pixels each being mounted at an intersection of each of said data electrodes and each of said scanning electrodes, common data electrodes each operating as a facing electrode of each of said pixels; a data driving section to write corresponding pixel data to each of said data electrodes based on a video signal strobe signal provided for every one horizontal period and to drive said liquid crystal panel with AC (Alternating Current) current in a predetermined manner based on a polarity inversion control signal provided for every one horizontal period; a gate driving section to output a scanning signal that synchronizes to a vertical synchronizing signal provided for every one vertical period and to drive each of said scanning electrodes in a predetermined order based on a vertical drive clock signal provided for every one horizontal period; and a control unit to output said video signal strobe signal and said polarity inversion control signal to said data driving section based on a video signal and to output said vertical synchronizing signal and said vertical drive clock signal to said gate driving section; wherein said one vertical period includes a blank period and a display period, and wherein said control unit provides a horizontal synchronizing signal stop period setting mode which sets a delay period in which outputting of a horizontal synchronizing signal comprising said video signal strobe signal and said vertical drive clock signal is delayed by X horizontal periods at least one time (X being a real number which is greater than zero) during said display period in said one vertical period, and shortens said blank period by a length of time equal to said delay period in said one vertical period.
