Abstract:
There is provided a method of driving a gate line, a gate drive circuit for performing the method, and a display apparatus having the gate drive circuit. In the method, a plurality of gate signals, generated from a plurality of shift registers connected to a plurality of gate lines, is applied to the gate lines. An output of the gate signals is blocked during a vertical blanking interval, and then a gate off voltage is applied to the gate lines. Therefore, an output signal of the gate drive circuit may maintain a gate off voltage during a vertical blanking interval in which a clock signal is not applied to a gate drive circuit.
