Claim 0:
1. A sensor device comprising:
first sensors;
second sensors forming capacitance with the first sensors;
a multi-frequency generator generating a first frequency signal and a second frequency signal having different frequencies;
a sensor transmitter 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
a sensor receiver 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, a first sensor of another group is not located within the first sub-groups, and a first sensor of another group is located between the first sub-groups.
