Claim 10:
11. The sensing circuit of claim 7, wherein, in the first sampling period, a first line selection signal, the sampling signal and the reference signal have an active level, and a second line selection signal and the channel connection signal have an inactive level,
wherein the first line selection switch is turned on in response to the first line selection signal having the active level, the first sampling switch and the second sampling switch are turned on in response to the sampling signal having the active level, the first sensing voltage of the first sensing line is applied to the first electrode of the sampling capacitor through the first line selection switch and the first sampling switch, and the initialization voltage is applied to the first electrode of the reference capacitor through the second sampling switch, and
wherein the first reference switch and the second reference switch are turned on in response to the reference signal having the active level, the reference voltage is applied to the second electrode of the sampling capacitor through the first reference switch, and the reference voltage is applied to the second electrode of the reference capacitor through the second reference switch.
