LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: A liquid crystal display is provided to minimize a deterioration effect in the picture quality by analyzing data of a particular pattern and compensating a common voltage according to an analyzed result. CONSTITUTION: A liquid crystal panel includes a plurality of pixels in which a plurality of gate lines and a plurality of data lines are arranged. A gate driver(110) successively drives a plurality of gate lines. A data driver(120) offers data signals to a plurality of data lines. A common voltage generation unit(140) supplies a common voltage to the liquid crystal display panel. A data analysis unit(160) analyzes a change of data levels in a particular pattern.
