Patent ID: 7425942

Claim:
A liquid crystal display apparatus comprising: pixels including red, green and blue color pixels arranged in a direction along a data line; gate line groups, each gate line group having a set of two gate lines electrically connected to each other, and each gate line crossing the data line; a data driver that drives the data line, wherein the data driver supplies data to the data line; a gate driver that drives the gate line groups; and a timing controller that controls the data driver and the gate driver, the timing controller having at least one line memory that temporarily stores data supplied to the data driver; wherein the timing controller includes three line memories to store red data, green data and blue data supplied to the liquid crystal display; wherein the timing controller modifies a data enable signal supplied to the timing controller to generate a modified data enable signal having period that is ⅓ of the horizontal period; wherein the data stored in the line memory is supplied to the data driver every one period of the modified data enable signal; wherein the gate driver sequentially supplies a first and a second gate pulse to each of the gate line groups; wherein the first gate pulse supplied to an i+1th gate line group is overlapped with the second gate pulse supplied to an ith gate line group in a portion of the period; wherein the first gate pulse has a pulse width that is narrower than the second gate pulse; wherein, when the second gate pulse is supplied to the ith gate line group and the first gate pulse is supplied to the i+1th gate line group, a second thin film transistor (TFT) is turned-on by the second gate pulse supplied to the ith gate line group and a first TFT is turned-on by the first gate pulse being provided via the turned-on second TFT, to thereby supply designated data to a color pixel connected to the first TFT, and when the first gate pulse supplied to the i+1th gate line group is off and only the second gate pulse is supplied to the ith gate line group, a third TFT formed in the ith gate line group is turned-on, to thereby supply designated data to a color pixel connected to the turned-on third TFT.
