Patent ID: 7928947

Claim:
A liquid crystal display device comprising: a liquid crystal panel including a plurality of first and second pixel cells supplied with data of the opposite polarities to display a picture; and at least one pre-charging unit to electrically connect a first one of the first pixel cells and a first one of the second pixel cells to each other just prior to a period of supplying the data to the first ones of the first and second pixel cells, and to electrically disconnect the first ones of the first and second pixel cells from each other for a period of supplying the data to the first and second pixel cells; a data driver supplying alternately a positive polarity data and a negative polarity data to data lines every two periods; a dummy gate line firstly driven in each frame period; wherein the liquid crystal panel includes a plurality of gate and data lines, wherein the gate lines cross the data lines; wherein the first one of first pixel cells is positioned at one side of an odd-numbered data line of the data lines, a second one of first pixel cells is positioned at the other side of the odd-numbered data line, and the first and second ones of the first pixel cells are connected to the odd-numbered data line in common, wherein the first one of second pixel cells is positioned at one side of an even-numbered data line of the data lines, a second one of second pixel cells is positioned at the other side of the even-numbered data line, and the first and second ones of the second pixel cells are connected to the even-numbered data line in common, wherein the first pixel cell positioned at one side of the odd-numbered data line and the second pixel cell positioned at one side of the even-numbered data line are connected to a first gate line of the gate lines in common, and wherein the first pixel cell positioned at the other side of the odd-numbered data line and the second pixel cell positioned at the other side of the even-numbered data line are connected to a second gate line of the gate lines in common; wherein a first pre-charging unit among pre-charging units is positioned in a first pixel row; wherein the first pre-charging unit positioned in the first pixel row is controlled by the dummy gate line.
