Abstract:
A scan driver includes active stages. Each active stage includes a first transistor that resets a control node, a second transistor that transfers a previous carry signal to the control node, a third transistor that transfers a scan clock signal to a scan output node, a first capacitor electrically connected between the control node and the scan output node, a fourth transistor that transfers a first low voltage to the scan output node, a fifth transistor that transfers a carry clock signal to a carry output node, a sixth transistor that electrically connects the control node to the carry output node, and a seventh transistor that transfers a second low voltage to the control node.
