Abstract
A liquid crystal display device includes a gate driving shift register having symmetrically split circuit portions by which each of plural gate lines is dually driven from both ends of the gate line during ripple-through scanning of rows of the LCD device. The LCD device includes a timing controller generating an output enable signal and a gate clock, where the timing controller adjusts a timing of a load signal for deciding a data output timing point when data will be loaded into a currently activated display row. The data output timing point is a function of a delay measuring feedback signal that is used to measure the cumulative delays of the sequentially connected stages of the shift register.
