LIQUID CRYSTAL DISPLAY AND DRIVING APPARATUS THEREOF

摘要

A signal controller of a liquid crystal display includes a logic circuit correcting n-bit source image data inputted from an external device into m-bit first corrected data, and a multilevel graying unit converting the m-bit first corrected data into second corrected data with a bit number equal to or less than n bits. A data driver outputting data voltages corresponding to the second corrected data from the signal controller is provided. The signal controller classifies the source image data into at least two sections and corrects the source image data into the first corrected data based on gamma correction data predetermined by gamma characteristics of the source image data for each of the at least two sections.
