Abstract
A method and apparatus for driving a liquid crystal display panel results in minimizing the deterioration of picture quality caused by a variation in the gate low voltage. A liquid crystal cell matrix is defined by intersections between gate lines and data lines. In the apparatus, a gate driver applies a gate high voltage to the gate lines in a corresponding first period, a first gate low voltage independent from other gate lines to the gate lines in the next second period, and a second gate low voltage depending on other gate lines to the gate lines in the next third period.
