Abstract:
A gate driver includes first and second stages. Each of the first and second stages includes an output circuit which outputs a scan signal, a carry signal and an inverted carry signal based on voltages of first and second nodes, a first input terminal, a second input terminal, a third input terminal, a first output terminal, and a second output terminal. The first stage further includes a first input circuit which controls the voltages of the first and second nodes thereof based on a start pulse and a signal supplied to the second input terminal. The second stage further includes a second input circuit which controls the voltages of the first and second nodes thereof based on a first carry signal and a first inverted carry signal, and a signal supplied to the second input terminal. The second stage is dependently connected to the first stage.
