Scan signal driver and a display device including the same

A scan signal driver, comprising:

• a plurality of stages for outputting scan signals and sensing signals,
• wherein a first stage among the stages is connected to a first scan signal line and a first sensing signal line, and
• wherein the first stage comprises:
• a first output unit configured to output a scan clock signal input to a first scan clock terminal to the first scan signal line as a first scan signal and to output a sensing clock signal input to a first sensing clock terminal to the first sensing signal line as a first sensing signal when a pull-up node has a gate-on voltage;
• and
• a sensing controller configured to apply the gate-on voltage to the pull-up node during a vertical blank period of a frame period when a sensing control signal of the gate-on voltage is input to a sensing control terminal during an active period of the frame period.

A display device, comprising:

• a display panel comprising data lines, scan signal lines and sensing signal lines, and pixels connected to the data lines, the scan signal lines and the sensing signal lines;
• a data driver for applying data voltages to the data lines;
• and
• a scan signal driver comprising a plurality of stages for applying scan signals to the scan signal lines and applying sensing signals to the sensing signal lines,
• wherein a first stage among the stages is connected to a first scan signal line and a first sensing signal line, and
• wherein the first stage comprises:
• a first output unit configured to output a scan clock signal input to a first scan clock terminal to the first scan signal line as a first scan signal and to output a sensing clock signal input to a first sensing clock terminal to the first sensing signal line as a first sensing signal when a pull-up node has a gate-on voltage;
• and
• a second output unit configured to output a carry clock signal input to a first carry clock terminal as a first carry signal to a carry output terminal when the pull-up node has the gate-on voltage,
• wherein the first stage is connected to a second scan-signal line and a second sensing signal line, and
• wherein the first output unit is configured to output another scan clock signal input to a second scan clock terminal to the second scan signal line as a second scan signal, and to output another sensing clock signal input to a second sensing clock terminal to the second sensing signal line as a second sensing signal when the pull-up node has the gate-on voltage.
