1. An input sensing device, comprising:
a sensor that includes a plurality of first electrodes and a plurality of second electrodes; and
a sensor driver that operates in a first sensing mode and a second sensing mode,
wherein, during the first sensing mode, the sensor driver generates a first sensing signal by transmitting transmission signals to the sensor and receiving first reception signals from the sensor,
wherein, during the second sensing mode, the sensor driver generates a second sensing signal by transmitting the transmission signals to the sensor and receiving second reception signals from the sensor, and
wherein the sensor driver selects one of a plurality of compensation maps based on the first sensing signal, compensates the second sensing signal based on the selected compensation map, and outputs a compensated sensing signal.
