Abstract

A low power gate driver circuit of a thin film transistor-liquid crystal display (TFT-LCD) recycling an electric charge, which controls the switching device, positioned between each of gate lines, and recycles the electric charge by discharging the electric charge which is charged in a capacitor of a gate line to a capacitor of another gate line, thereby capable of reducing energy which a gate driver consumes.
