Abstract: An input sensing device includes 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. During the first sensing mode, the sensor driver generates a first sensing signal by transmitting transmission signals to the sensor and receiving reception signals from the sensor. During the second sensing mode, the sensor driver generates a second sensing signal by transmitting the transmission signals to the sensor and receiving the reception signals from the sensor. The sensor driver selects one of a plurality of compensation maps based on the first sensing signal, compensates for the second sensing signal based on the selected compensation map, and outputs the compensated sensing signal.
