Claim 0:
1. A display device comprising:
a first pixel comprising a first scanning transistor coupled to a first scan line and a first data line and a first sensing transistor coupled to a first sensing line;
a second pixel comprising a second scanning transistor coupled to the first scan line and a second data line and a second sensing transistor coupled to a second sensing line; and
a sensor, the sensor comprising:
a first sensing channel connected to the first sensing line through a first switch and including a first sampling capacitor; and
a second sensing channel connected to the second sensing line through a second switch and including a second sampling capacitor,
wherein, during a first period, the first sensing channel stores a first sampling signal in the first sampling capacitor while the first switch is turned on, and the second sensing channel stores a second sampling signal in the second sampling capacitor while the second switch is turned off.
