Stage circuit and scan driver using the same

摘要

A stage circuit includes a first driver, a second driver, a first output unit and a second output unit. The first driver controls voltages of first and second nodes, according to a first power source, a start signal or a carry signal of a previous stage supplied to a first input terminal, a first clock signal supplied to a second input terminal, and a second clock signal supplied to a third input terminal. The second driver controls a voltage of a third node, according to the first power source, a start signal or a carry signal of a previous stage supplied to a first input terminal, a carry signal of a next stage supplied to a fourth input terminal, and the voltage of the second node.
