1. A sensor device comprising:
a sensor panel including sensors arranged in a matrix form and sensor lines electrically connected to the sensors one-to-one; and
a sensor driver configured to receive sensing signals from the sensors through the sensor lines,
wherein the sensor driver is configured to simultaneously receive a first sensing signal from a first sensor using a first reference signal and a second sensing signal from a second sensor using a second reference signal,
wherein the first reference signal and the second reference signal have a same waveform, a phase of the second reference signal is different from a phase of the first reference signal, and
wherein a phase of the second sensing signal is different from a phase of the first sensing signal.
