US 2013/0278570 A1 · GATE DRIVING CIRCUIT AND DISPLAY APPARATUS HAVING THE SAME

Abstract

A gate driving circuit includes first to n-th gate clock lines, first to m-th selection lines, a holding control line, a voltage line and a plurality of stages. The first to n-th gate clock lines transfer first to n-th gate clock signals. The first to m-th selection lines transfer first to m-th gate selection signals. The holding control line transfers a holding control signal. The voltage line transfers a gate-off voltage. The stages outputs a plurality of gate signals, each stage outputs a high voltage of a gate clock signal as a gate-on voltage of a gate signal in response to a high voltage of a gate selection signal, and outputs the gate-off voltage in response to a high voltage of the holding control signal.
