Patent ID: 7817122

Claim:
A method of driving a liquid crystal display (LCD) panel, comprising: applying a common voltage to a common electrode of the LCD panel, the LCD panel including a liquid crystal (LC) cell including a pixel electrode; sequentially applying a gate signal voltage to a gate line of the LCD panel; alternately applying a first data signal voltage and a second data signal voltage to a data line every a frame, wherein the first data signal voltage and the second data signal voltage have an opposite polarity each other; applying a first compensation voltage to the pixel electrode for a first period of a present frame, wherein the first period is the high level state of the gate signal voltage; applying a first data signal voltage for a second period of a present frame after the applying the first compensation voltage to the pixel electrode, wherein a voltage difference between the first compensation voltage and the common voltage is greater than a voltage difference between the first data signal voltage and the common voltage; and applying a second compensation voltage different from the first compensation voltage to the pixel electrode during a third period of the present frame after applying the first data signal voltage to the pixel electrode and before a next frame following the present frame, wherein the second data signal voltage is applied to the data line from the third period of the present frame, wherein the second compensation voltage has an opposite polarity of the first data signal voltage and the second compensation voltage is applied to a data line before applying the next gate signal voltage for the next frame, wherein the second compensation voltage has an absolute value greater than the second data signal voltage.
