Abstract:
1. A liquid crystal display, comprising: a liquid crystal display panel comprising a plurality of pixels, each pixel comprising a switching element, a liquid crystal capacitor comprising a first electrode and a second electrode, and a storage capacitor comprising a third electrode and a fourth electrode, wherein the first electrode and the third electrode are commonly electrically connected to the switching element; a driving voltage generator generating a common electrode voltage, wherein the common electrode voltage is distorted into a common electrode distortion voltage which is applied to the second electrode of the liquid crystal capacitor; a distortion detector receiving the common electrode voltage and outputting the common electrode distortion voltage in response to the common electrode voltage; and an offset voltage generator receiving the common electrode distortion voltage from the distortion detector and outputting an offset voltage based on an AC component of the common electrode distortion voltage to the fourth electrode of the storage capacitor, wherein the offset voltage is out of phase with respect to the common electrode distortion voltage.
