LIQUID CRYSTAL DISPLAY AND METHOD OF DRIVING THE SAME

摘要

A liquid crystal display includes: a signal controller configured to receive an input image signal corresponding to a gray from the outside, and an image signal corrector configured to correct the input image signal. The image signal corrector is configured to shift a first input image signal value corresponding to a black gray by a first value based on a common voltage, is configured to shift a second input image signal value corresponding to a halftone gray by a second value based on the common voltage, and is configured to shift a third input image signal value corresponding to a white gray by a third value based on the common voltage. The first value and the second value are larger than a kickback voltage of each of the black gray and the halftone gray, and the third value is the same as a kickback voltage of the white gray.

1. A liquid crystal display, comprising:
a signal controller configured to receive an input image signal corresponding to a gray from the outside; an image signal corrector configured to correct the input image signal to generate a data input signal; and a data driver configured to supply a data voltage corresponding to the gray based on the data input signal, wherein the gray includes a black gray, a white gray, and a halftone gray between the black gray and the white gray, wherein the image signal corrector is configured to shift a first input image signal value corresponding to the black gray by a first value based on a common voltage, the image signal corrector is configured to shift a second input image signal value corresponding to the halftone gray by a second value based on the common voltage, and the image signal corrector is configured to shift a third input image signal value corresponding to the white gray by a third value based on the common voltage, and wherein the first value and the second value are larger than a kickback voltage of each of the black gray and the halftone gray, and the third value is the same as a kickback voltage of the white gray.
