Disclosed is an improved gate line driver and method for a liquid crystal display. The method includes: receiving a horizontal synchronous Fh signal; and producing at least two non-overlapping gate line pulses during each period of the Fh signal. A first way to produce the gate line pulses is to: produce a gate shift clock GSC signal having a frequency f(GSC) at least twice as great as the frequency of the Fh signal f(Fh) such that f(GSC)>/=f(Fh); and provide one gate line pulse during each period of the GSC signal. A second way to produce the gate line pulses is to: produce a gate shift clock GSC signal having a frequency f(GSC) the same as the frequency of the Fh signal f(Fh) such that f(GSC)=f(Fh); move a pulse through a plurality of shift registers according to the GSC signal; logically combine, e.g., by ANDing, the GSC signal and the sequence of shift register pulses to provide one of the gate line pulses during each period of the Fh signal; and logically combine, e.g., by ANDing, the inverted GSC signal and the sequence of shift register pulses to provide another one of the gate line pulses during each period of the Fh signal.
