A scan signal driver includes: stages to sequentially output scan signals in an active period, and to selectively output sensing signals in a vertical blank period. At least one of the stages includes: a sensing control circuit to supply a gate-on voltage to a sensing control node in response to a holding control signal during the active period, and to output the gate-on voltage of the sensing control node in response to a selectively input line select signal during the vertical blank period; an output node control circuit to supply the gate-on voltage to a pull-up node when the gate-on voltage of the sensing control node is output during the vertical blank period; and an output circuit to output a scan clock signal as a sensing signal to one of scan signal lines when the gate-on voltage is supplied to the pull-up node during the vertical blank period.

Scan signal driver and display device including the same

A scan signal driver includes: a plurality of stages configured to be driven by dividing a first frame period into a display period and a sensing period, and to sequentially output scan signals at the display period, wherein each of the plurality of stages comprises: an output control circuit; and a memory control circuit, wherein the scan driver is configured to: irregularly set a specific stage of the plurality of stages at a display period every frame; control the specific stage to: store a voltage by using the memory control circuit; and output a sensing signal by using the stored voltage at a sensing period, and the memory control circuit includes: a second memory transistor configured to electrically connect an M node with an I node; and a third memory transistor configured to electrically connect the output control circuit with the I node.
