Abstract:
1. A liquid crystal display, comprising: a liquid crystal panel including a plurality of gate lines, a plurality of data lines intersecting the gate lines, and a plurality of pixels provided near the intersections of the gate lines and the data lines; a timing controller receiving image data and synchronization signals from an external graphics source, performing format conversion for the image data and generating control signals required for driving the liquid crystal panel; a voltage generator generating gray voltages and gate voltages required for the liquid crystal panel; a gate driver sequentially scanning the gate lines of the liquid crystal panel by unit of one horizontal scanning period based on the gate voltages; and a data driver arranges the image data from the timing controller corresponding to the data lines of the liquid crystal panel, selecting the gray voltages corresponding to the image data, and applying the selected voltages the pixels connected to the scanned the gate lines through the data lines, wherein the data driver reverses the polarity of the gray voltages to be applied to the data lines of the liquid crystal panel by a predetermined number of rows, and biases the data lines to a voltage with a predetermined level before outputting the gray voltages to the pixels in each scanned row.
