1. A display device, comprising:
a display panel comprising pixels;
a sensor layer overlapping the display panel and comprising sensors; and
a sensor driver configured to transmit a driving signal to the sensors and receive sensing signals from the sensors, wherein:
in a first mode, the sensor driver is configured to transmit a first driving signal to the sensors to detect a first sensing area where a touch occurs, and,
in a second mode, the sensor driver is configured to transmit a second driving signal to at least a portion of the sensors corresponding to a second sensing area different from the first sensing area,
wherein the first driving signal and the second driving signal are different from each other in voltage magnitude.
