ABSTRACT:
A liquid crystal panel driving method and apparatus for a dot-inversion system is adaptive for constantly maintaining a voltage applied to each liquid crystal cell, wherein a ‘n−1’th(n≧2) cell of adjacent pixel cells is charged and then a nth cell thereof is charged for a shorter time period than the ‘n−1’th(n≧2) cell. Accordingly, the liquid crystal cells positioned adjacent to each other receive video signals having the same polarity during a different time period. Therefore, the liquid crystal cells positioned adjacent to each other to receive video signals having the same polarity can be coupled with an equal voltage.
