Patent ID: 7450098

Claim:
A liquid crystal display comprising: a liquid crystal panel assembly including a plurality of gate lines, a data line intersecting the gate lines, and a plurality of pixels connected to the gate lines and the data line; a signal controller configured to receive image data and a synchronization signal from an external device, process the image data and generate control signals for displaying the image data; a voltage generator configured to generate a plurality of gray voltages and a gate voltage for driving the panel assembly; a gate driver configured to sequentially scan the gate lines by applying the gate voltage, each scanning being performed in a horizontal period including a first sub-period and a second sub-period following the first sub-period; a master data driver configured to sequentially apply to the data line one of the data voltages selected from the gray voltages corresponding to the image data, wherein each application is performed in the second sub-period of a present horizontal period; and a slave data driver configured to store the data voltage applied to the data line in the second sub-period of the present horizontal period and apply the stored data voltage to the data line in the first sub-period of a next horizontal period.
