Abstract

A method of driving a liquid crystal display to eliminate stripe-shaped noise when a picture screen is displayed on an enlarged viewing area includes dividing a liquid crystal into a plurality of blocks, and setting widths of scanning pulses for a gate electrode pair supplied with the same data differently for each block, wherein the gate electrode pair includes first and second gate lines.
