Claim 17:
18. A driving method of a sensor device including first sensors and second sensors forming capacitance with the first sensors, comprising:
generating a first frequency signal and a second frequency signal having different frequencies;
supplying first driving signals based on the first frequency signal to first sensors of a first group among the first sensors and simultaneously supplying second driving signals based on the second frequency signal to first sensors of a second group among the first sensors; and
simultaneously receiving sensing signals from the second sensors,
wherein each two or more first sensors of the first group forms each of first sub-groups, and a first sensor of another group is not located within the first sub-groups,
wherein each two or more first sensors of the second group forms each of second sub-groups, and a first sensor of another group is not located within the second sub-groups, and
wherein the first sub-groups and the second sub-groups are alternately arranged.
