摘要： 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.

摘要： A gate driving method and apparatus for a liquid crystal display panel is disclosed that minimizes deterioration of picture quality caused by a variation in a gate low voltage. A liquid crystal cell matrix is defined by intersections between gate lines and data lines having corresponding thin film transistors. A gate driver applies a gate high voltage, which is at least equal to the turn-on voltages of the thin film transistors, to the gate lines in a corresponding period, and applies an independent gate low voltage to the gate lines divided into a plurality of blocks as turn-off voltages of the thin film transistors in each block.
