Abstract
A stage of a scan driver includes: a first driving controller for controlling a voltage of a first node and a voltage of a second node; a second driving controller for controlling a voltage of a first driving node, based on a sensing-on signal, a next carry signal, a first control clock signal, a second control clock signal, the voltage of the first node, and a voltage of a sampling node, and controlling a voltage of a second driving node, based on the voltage of the sampling node and the voltage of the first driving node; an output buffer for outputting a carry signal, the first scan signal, and the second scan signal; and a coupling controller. The second driving controller maintains the voltage of the first driving node as a gate-off voltage in response to the voltage of the second driving node and a third control clock signal.
