Abstract
A sensor device of the disclosure includes first sensors, second sensors forming a capacitance with the first sensors, and a sensor driver configured to transmit driving signals to the first sensors and receive sensing signals from the second sensors. The sensor driver simultaneously transmits driving signals to at least two first sensors during a first period and does not transmit driving signals to the rest of the first sensors during the first period, and the sensor driver transmits an offset signal to at least one of the second sensors during the first period and receives the sensing signals from at least two of the second sensors other than the at least one of the second sensors during the first period.
