Abstract

A liquid crystal display includes a plurality of pixels; an image signal modifier comparing a previous image signal and a current image signal, modifying the current image signal based on the comparison result to generate a first modified image signal, calculating an average modified value, and modifying the first modified image signal into a second modified image signal based on the average modified value; and a data driver supplying a data voltage corresponding to the second modified image signal to the pixel.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2005-0117583 filed with the Korean Intellectual Property Office on December 5, 2005, the contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a liquid crystal display and a correction method for its image signal. Background technique [0004] A liquid crystal display (LCD) includes a pair of panels having field generating electrodes and a liquid crystal (LC) layer having dielectric anisotropy interposed between the two panels. The field generating electrodes generally include a common electrode and a plurality of pixel electrodes arranged in a matrix connected to switching elements such as thin film transistors (TFTs) supplied with data voltages. A pair of field generating electrodes and a liquid crystal layer form a liquid crystal capacitor. The strength of the electric field determines the ori...
