ABSTRACT:
A driving method of an LCD device adapted to improve the quality of pictures is disclosed. The driving method includes: deriving a frame detection signal from a data enable signal and a data clock signal; simultaneously deriving a start signal and a first gate clock signal from the frame detection signal and the data clock signal; and deriving a second gate clock signal from the first gate clock signal and the data clock signal. The first gate clock signal is identical with the start signal in a start time point of enable interval.
