Stage circuit and emission control driver using the same

摘要

A stage circuit including an output unit for supplying first or second power source to an output terminal is disclosed. The stage circuit may comprise a bidirectional driver for respectively supplying signals supplied to first and second input terminals, a first driver, and a second driver. The second driver controls the output unit to output the second power source to the output terminal without any voltage loss, corresponding to a second clock signal.
