Abstract:
A liquid crystal display module comprising:a liquid crystal display panel having data lines, gate lines and liquid crystal cells each connected to one of said data lines and one of said gate lines; and a plurality of data line drive apparatuses, provided at an edge of said liquid crystal display panel and connected by a cascade connection to each other, for driving said data lines, each of said data line drive apparatuses comprising: a plurality of voltage followers; a plurality of output pads each connected to one of said data lines; a plurality of first switches each connected between one of said voltage followers and one of said output pads; a plurality of second switches each connected between two of said output pads; first and second charge neutralization pads, said second charge neutralization pad being connected to a most-downstream one of said output pads; and a third switch connected between said first charge neutralization pad and a most-upstream one of said output pads, said first, second and third switches being turned OFF, ON and ON, respectively, by a first state of a strobe signal, said first, second and third switches being turned ON, OFF and OFF, respectively, by a second state of said strobe signal, said first charge neutralization pad of one of said data line drive apparatuses being electrically connected to said second charge neutralization pad of another of said data line drive apparatuses upstream of said one of said data line drive apparatuses, said second charge neutralization pad of one of said data line drive apparatuses being electrically connected to said second charge neutralization pad of another of said data line drive apparatuses downstream of said one of said data line drive apparatuses.
