Gate driving circuit and electroluminescent display using the same

An electroluminescent display comprising:

• pixels connected to gate lines;
• and
• a gate driving circuit to supply a gate signal to at least one of the gate lines, and composed of a plurality of stages connected to each other in a cascading way,
• wherein an nth (n is a positive integer) stage of the gate driving circuit comprises:
• a Q1 node charging unit to charge a Q1 node to a turn-on voltage using a first and a second clock signal,
• a pull-up transistor to apply a turn-on voltage to an output terminal in response to a voltage of the Q1 node,
• a pull-down unit to control the output terminal to output a turn-off voltage in response to a voltage of a QB1 node;
• and
• a node controller to control the voltage of the QB1 node to a level opposite to a level of the voltage of the Q1 node,
• wherein the Q1 node charging unit comprises:
• a first charging unit to charge the voltage of the Q1 node to a turn-on voltage using the second clock signal, and
• a second charging unit to charge a Q2 node, coupled to the Q1 node, using the first clock signal in a section where the Q1 node has a turn-on voltage,
• wherein the node controller comprises:
• a QB2 node controller to apply a turn-on voltage of the first clock signal to a QB2 node in response to a voltage of a QP node, and
• wherein the QB2 node controller further comprises:
• a second capacitor connected between the QP node and the QB2 node;
• and
• a QP node controller connected between a QB2 node of a (n-1)th stage and the QP node.
