Liquid Crystal Display and Gate Driving Circuit Thereof
First Claim
1. A gate driving circuit comprising:
- a circuit unit having a plurality of stages dependently connected to each other to output a gate clock pulse or a gate clock bar pulse as a gate driving signal for each of the gate lines in response to a single start pulse; and
a line unit having a start pulse line receiving the start pulse to provide the received start pulse to an input terminal of each of a first odd-numbered stage and a first even-numbered stage of the stages,wherein output terminals of the stages are connected to the gate lines, respectively.

Abstract
A liquid crystal display and a dual gate driving circuit therefor wherein the number of signal lines are reduced by sharing a start pulse and an output signal of a dummy stage. The liquid crystal display includes a timing controller generating an output enable signal, a gate clock, and a signal start signal in response to an external input signal, a level shifter generating a gate clock pulse and a gate clock bar pulse in response to the output enable signal and the gate clock and generating a single start pulse in response to the start signal and the gate clock, and first and second gate driving circuits outputting the gate clock pulse or the gate clock bar pulse as a gate driving signal to the plurality of gate lines in response to the single start pulse.
