Abstract
A sensor device includes: first sensors; second sensors which forms a capacitance with the first sensors; and a sensor driver which transmits driving signals to the first sensors through first sensor lines, and receives sensing signals from the second sensors through second sensor lines. The sensor driver sequentially transmits the driving signals to the first sensors, and transmits, during each period of transmitting the driving signals, an offset signal, which is identical in frequency to and different in phase from the driving signals, to at least one selected from first sensors which does not receive the driving signals among the first sensor. The sensor driver sets at least one selected from a slew rate and a voltage level of the offset signal to a value different from a corresponding value of a corresponding driving signal.
