GATE DRIVING CIRCUIT AND ELECTROLUMINESCENT DISPLAY DEVICE USING THE SAME

Abstract:

A gate driving circuit includes a plurality of stages that are dependently connected, wherein an n-th one of the stages (n being a natural number) comprises a node controller for controlling voltages of set and reset nodes, a scan signal generator controlled in accordance with the voltages of the set and reset nodes, thereby outputting a scan signal to a scan line of a display panel, and a reference voltage/high-level supply power output unit controlled in accordance with the voltages of the set and reset nodes, thereby outputting a reference voltage or a high-level supply voltage to a reference voltage line of the display panel.
