Abstract

A stage and a scan driver having the same. The stage outputs a scan signal and a sensing signal to a scan line and a sensing line, respectively. The stage includes a first controller configured to control a voltage of a sensing node and a driving node based on first to third control signals and a carry signal of the stage and another stage connected to the stage, a second controller configured to control a voltage of an inversion driving node based on a first carry clock signal, the voltage of the driving node, and the third control signal, and a first output buffer configured to output a second carry clock signal or a second low potential power as the carry signal in correspondence with the voltage of the driving node and the inversion driving node.
