Abstract:
1. A liquid crystal display (LCD) having a multi-frame inversion function, comprising: a timing controller having a multiframe inversion driving portion for modulating a reversal (REV) signal that designates a polarity of a data voltage for switching the polarity of liquid crystals on an LCD panel with respect to a common electrode voltage, thereby generating a modulated REV signal; a gate driver for generating a gate driving voltage; a data driver for generating a data driving voltage based on the modulated REV signal received from the timing controller; and an LCD panel having a plurality of gate lines, a plurality of data lines, a plurality of switching elements each formed in an area surrounded by the gate lines and the data lines and connected to the gate lines and the data lines, and a plurality of dot electrodes connected to the switching elements and operated in response to the switching elements, wherein inversion drive repeats in a period of p frames based on the gate driving voltage and the data driving voltage, and the inversion is performed by shifting down by every line in a period of one as the frame changes, and a plurality of REV signals have sequential 1/p phase differences.
